Account budgets control what an account can spend over a specific period of time
by defining budget properties like spend limit, start time, and end time. They
must point to one of the account's billing setups, to indicate which specific
Payments account will be billed. You can create, update, and remove the
[`AccountBudget`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudget) in the Google Ads API by sending
[`AccountBudgetProposal`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal) objects.

[`AccountBudget`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudget) objects represent the end result of applying
proposals. After a proposal is approved, its changes (subject to any
adjustments) will result in the creation of a new account budget or an update to
an existing one. This depends on the [`proposal_type`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal#proposal_type) specified
in the request.

| [`AccountBudgetProposalType`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalTypeEnum.AccountBudgetProposalType) | Description |
|---|---|
| [`CREATE`](https://developers.google.com/google-ads/api/docs/billing/account-budgets#create) | Creates a new account budget, which must be approved before use. |
| [`UPDATE`](https://developers.google.com/google-ads/api/docs/billing/account-budgets#update) | Modifies an existing account budget. |
| [`END`](https://developers.google.com/google-ads/api/docs/billing/account-budgets#end) | Sets an account budget's end time to the current time. |
| [`REMOVE`](https://developers.google.com/google-ads/api/docs/billing/account-budgets#remove) | Removes an account budget prior to its start time. |

> [!IMPORTANT]
> **Key Point:** [`AccountBudgetProposal`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal) objects are reviewed by Google prior to being applied. Reviews are typically completed in less than one hour; however, you should ensure that budgets are approved well in advance of their requested start time.

The following sections describe the behavior of each proposal type.

## Create an account budget proposal

Creating a new account budget lets you control a customer's spending
behavior. Use the [`AccountBudgetProposalService`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalService) to create a
new [`AccountBudgetProposal`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal). You should set
[`proposal_type`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal#proposal_type) to [`CREATE`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalTypeEnum.AccountBudgetProposalType#create) to specify
that a new budget should be created. Refer to the [management](https://developers.google.com/google-ads/api/docs/billing/account-budgets#management)
section of this guide for other operations.

Remember to use a billing setup with a Payments account where you have write
access. Refer to the [billing setup guide](https://developers.google.com/google-ads/api/docs/billing/billing-setups) for
details.

The following example demonstrates how to create a new budget proposal.


### Java

```java
private void runExample(GoogleAdsClient googleAdsClient, long customerId, long billingSetupId) {
  // Creates an AccountBudgetProposal. This will be reviewed offline by Google Ads, and if
  // approved will become an AccountBudget.
  AccountBudgetProposal proposal =
      AccountBudgetProposal.newBuilder()
          .setBillingSetup(ResourceNames.billingSetup(customerId, billingSetupId))
          .setProposalType(AccountBudgetProposalType.CREATE)
          .setProposedName("Account Budget (example)")

          // Specifies the account budget starts immediately.
          .setProposedStartTimeType(TimeType.NOW)
          // Alternatively you can specify a specific start time. Refer to the
          // AccountBudgetProposal
          // resource documentation for allowed formats.
          //
          // .setProposedStartDateTime("2020-01-02 03:04:05")

          // Specifies that the budget runs forever.
          .setProposedEndTimeType(TimeType.FOREVER)
          // Alternatively you can specify a specific end time. Allowed formats are as above.
          // .setProposedEndDateTime("2021-02-03 04:05:06")

          // Optional: sets notes for the budget. These are free text and do not effect budget
          // delivery.
          // .setProposedNotes("Received prepayment of $0.01")

          // Sets the spending limit to 0.01, measured in the Google Ads account currency.
          .setProposedSpendingLimitMicros(10_000)

          // Optional: sets PO number for record keeping. This value is at the user's
          // discretion, and has no effect on Google Billing & Payments.
          // .setProposedPurchaseOrderNumber("PO number 12345")
          .build();

  // Creates an operation which will add the new AccountBudgetProposal.
  AccountBudgetProposalOperation operation =
      AccountBudgetProposalOperation.newBuilder().setCreate(proposal).build();

  try (AccountBudgetProposalServiceClient accountBudgetProposalServiceClient =
      googleAdsClient.getLatestVersion().createAccountBudgetProposalServiceClient()) {
    // Sends the request to the Account Budget Proposal Service.
    MutateAccountBudgetProposalResponse response =
        accountBudgetProposalServiceClient.mutateAccountBudgetProposal(
            String.valueOf(customerId), operation);

    System.out.printf(
        "Account budget proposal created: %s.%n", response.getResult().getResourceName());
  }
}
      
```

### C#

```c#

    AccountBudgetProposalServiceClient proposalService =
        client.GetService(Services.V26.AccountBudgetProposalService);

    // Create an AccountBudgetProposal. The proposal will be reviewed offline by Google Ads,
    // and if approved will become an AccountBudget.
    AccountBudgetProposal proposal = new AccountBudgetProposal()
    {
        BillingSetup = ResourceNames.BillingSetup(customerId, billingSetupId),
        ProposalType = AccountBudgetProposalType.Create,
        ProposedName = "Account Budget (example)",

        // Specify the account budget starts immediately
        ProposedStartTimeType = TimeType.Now,

<br />

> [!NOTE]
> **Note:** Only one active account budget is allowed per customer. To create a new account budget, any existing budget must have an end date that's *before* the start date of the new budget.

In account budget proposal requests,
[`proposed_start_date_time`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal#proposed_start_date_time) and
[`proposed_end_date_time`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal#proposed_end_date_time) are always in the customer's
account timezone; you cannot specify a timezone. The
[proposed spending limit](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal#proposed_spending_limit_micros) is always measured in
the account's currency; specify this using "micro" units, so $1.00 = 1,000,000
micros.

Optionally, you can include a purchase order number which will show next to
these charges on the invoice. This does not have any effect on budget delivery.

### Remove a pending account budget proposal

You can remove an entire pending budget proposal by sending an
[`AccountBudgetProposalOperation.remove`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalOperation#remove) request
with an account budget proposal resource name. However, note that budget
proposals are usually applied within minutes.
Java

```
AccountBudgetProposalOperation operation = AccountBudgetProposalOperation.newBuilder()
  .setRemove(ResourceNames.accountBudgetProposal(customerId, accountBudgetProposalId))
  .build();

// Send request to Google Ads API (not shown).
```
C#

```
AccountBudgetProposalOperation operation = new AccountBudgetProposalOperation()
{
    Remove = ResourceNames.AccountBudgetProposal(customerId, accountBudgetProposalId)
};

// Send request to Google Ads API (not shown).
```
PHP

```
$accountBudgetProposalOperation = new AccountBudgetProposalOperation();
$accountBudgetProposalOperation->setRemove(ResourceNames::forAccountBudgetProposal($customerId, $accountBudgetProposalId));

// Send request to Google Ads API (not shown).
```
Python

```
account_budget_proposal_service = client.get_service('AccountBudgetProposalService')
account_budget_proposal_operation = client.get_type('AccountBudgetProposalOperation')
account_budget_proposal_operation.remove = (
    account_budget_proposal_service.account_budget_proposal_path(
        customer_id, account_budget_proposal_id
    )
)

# Send request to Google Ads API (not shown).
```
Ruby

```
operation = client.operation.remove_resource.account_budget_proposal(client.path.account_budget_proposal(customer_id, account_budget_proposal_id))

# Send request to Google Ads API (not shown).
```
Perl

```
my $account_budget_proposal_operation =
  Google::Ads::GoogleAds::V26::Services::AccountBudgetProposalService::AccountBudgetProposalOperation
    ->new({
      remove => Google::Ads::GoogleAds::V26::Utils::ResourceNames::account_budget_proposal(
          $customer_id, $account_budget_proposal_id
        )
    });

# Send request to Google Ads API (not shown).
```

If you made a mistake with the original proposal, you can resubmit the
proposal as an `UPDATE` operation. Refer to
[Update an existing account budget](https://developers.google.com/google-ads/api/docs/billing/account-budgets#update).

## Retrieve existing account budgets

The following Google Ads Query Language (GAQL) query fetches all of the existing account budgets
in an account:

    SELECT
      account_budget.resource_name,
      account_budget.id,
      account_budget.name,
      account_budget.status,
      account_budget.billing_setup,
      account_budget.approved_spending_limit_micros,
      account_budget.approved_spending_limit_type,
      account_budget.proposed_spending_limit_micros,
      account_budget.proposed_spending_limit_type,
      account_budget.adjusted_spending_limit_micros,
      account_budget.adjusted_spending_limit_type,
      account_budget.approved_start_date_time,
      account_budget.proposed_start_date_time,
      account_budget.approved_end_date_time,
      account_budget.approved_end_time_type,
      account_budget.proposed_end_date_time,
      account_budget.proposed_end_time_type
    FROM
      account_budget

> [!IMPORTANT]
> **Key Point:** `approved_start_date_time` will always be null for the account budgets created before 2019. Use `proposed_start_date_time` instead.

Fields that encapsulate the account budget's start time, end time, and
spending limit have multiple variants with prefixes such as `proposed` and
`approved` that allow for comparing the values that were initially proposed with
those that were approved. The spending limit has additional fields with the
`adjusted` prefix to indicate the current spending limit in effect after any
adjustments were applied to the approved amount.

An account budget's approved spending limit can be adjusted over time to
reflect various credits for things like budget overdelivery, invalid click
activity, and promotional coupons. More information
[about account budgets](https://support.google.com/google-ads/answer/7054229) and
[account credits and adjustments](https://support.google.com/google-ads/answer/1704323)
can be found in the Google Ads Help Center.

Any new account budgets pending approval, along with any existing account
budgets that have updates pending, will also populate the
[`pending_proposal`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudget#pending_proposal) nested message, whose subfields can be
selected in a GAQL query (such as
[`account_budget_proposal`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudget.PendingAccountBudgetProposal#account_budget_proposal), queried as
`account_budget.pending_proposal.account_budget_proposal`, for the resource
name of the associated [`AccountBudgetProposal`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal)
object).

## Manage existing account budgets

After you create an account budget for a customer, you can use the
[`AccountBudgetProposalService`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalService) to manage the budget
parameters. The most common management operations are to update the
`proposed_spending_limit_micros` and `proposed_end_date_time` fields. For a
complete list of the mutable fields, refer to the
[`AccountBudgetProposal`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal) reference documentation.

You have the option of updating an existing account budget or creating an
entirely new budget; both are shown here.

### Update an existing account budget

You can update the existing account budget fields by sending
[`AccountBudgetProposal`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal) objects with
[`AccountBudgetProposalType`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalTypeEnum.AccountBudgetProposalType) set to `UPDATE`. Note that you
must also indicate the fields being updated in the operation's `update_mask`
argument.

The following snippet demonstrates how to update the proposed spending limit
for an existing account budget.
Java

```
AccountBudgetProposal proposal = AccountBudgetProposal.newBuilder()
  .setProposalType(AccountBudgetProposalType.UPDATE)
  .setAccountBudget(accountBudget.getResourceName())
  .setProposedSpendingLimitMicros(
    accountBudget.getProposedSpendingLimitMicros() + increaseAmount)
  .build();

AccountBudgetProposalOperation operation = AccountBudgetProposalOperation.newBuilder()
  .setCreate(proposal)
  .setUpdateMask(
      FieldMask.newBuilder().addAllPaths(Arrays.asList("proposed_spending_limit_micros")).build())
  .build();

// Send request to Google Ads API (not shown).
```
C#

```
AccountBudgetProposal proposal = new AccountBudgetProposal()
{
  ProposalType = AccountBudgetProposalType.Update,
  AccountBudget = accountBudget.ResourceName,
  ProposedSpendingLimitMicros = accountBudget.ProposedSpendingLimitMicros + increaseAmount
};

AccountBudgetProposalOperation operation = new AccountBudgetProposalOperation()
{
  Create = proposal,
  UpdateMask = new FieldMask()
  {
    Paths = { "proposed_spending_limit_micros" }
  }
};

// Send request to Google Ads API (not shown).
```
PHP

```

### Account budget chaining

As an alternative to updating the existing budget, Google Ads lets you chain
multiple account budgets to run in succession. In the following example, a
customer has different spending limits each month.
![Diagram showing a chain of account budgets with different spending limits each month.](https://developers.google.com/static/google-ads/api/images/account-budget-chaining.png) Example of account budget chaining.

This can be achieved by creating three
[`AccountBudgetProposal`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposal) objects and sending each
[`AccountBudgetProposalOperation`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalOperation) to the
[`AccountBudgetProposalService`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalService) in a separate
`MutateAccountBudgetProposal` request (since
`MutateAccountBudgetProposalRequest` accepts a single `operation` per call).

The following snippet demonstrates the creation of such a chain using an
existing billing setup.
Java

```
AccountBudgetProposal proposalMay = AccountBudgetProposal.newBuilder()
  .setBillingSetup(ResourceNames.billingSetup(customerId, billingSetupId))
  .setProposalType(AccountBudgetProposalType.CREATE)
  .setProposedName("May budget")
  .setProposedStartDateTime("2027-05-01 00:00:00")
  .setProposedEndDateTime("2027-06-01 00:00:00")
  .setProposedSpendingLimitMicros(1_000_000_000L)
  .build();

AccountBudgetProposalOperation operationMay = AccountBudgetProposalOperation.newBuilder()
  .setCreate(proposalMay)
  .build();

AccountBudgetProposal proposalJune = AccountBudgetProposal.newBuilder()
  .setBillingSetup(ResourceNames.billingSetup(customerId, billingSetupId))
  .setProposalType(AccountBudgetProposalType.CREATE)
  .setProposedName("June budget")
  .setProposedStartDateTime("2027-06-01 00:00:00")
  .setProposedEndDateTime("2027-07-01 00:00:00")
  .setProposedSpendingLimitMicros(5_000_000_000L)
  .build();

AccountBudgetProposalOperation operationJune = AccountBudgetProposalOperation.newBuilder()
  .setCreate(proposalJune)
  .build();

AccountBudgetProposal proposalJuly = AccountBudgetProposal.newBuilder()
  .setBillingSetup(ResourceNames.billingSetup(customerId, billingSetupId))
  .setProposalType(AccountBudgetProposalType.CREATE)
  .setProposedName("July budget")
  .setProposedStartDateTime("2027-07-01 00:00:00")
  .setProposedEndDateTime("2027-08-01 00:00:00")
  .setProposedSpendingLimitMicros(1_000_000_000L)
  .build();

AccountBudgetProposalOperation operationJuly = AccountBudgetProposalOperation.newBuilder()
  .setCreate(proposalJuly)
  .build();

```

Note the use of [`AccountBudgetProposalType.CREATE`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalTypeEnum.AccountBudgetProposalType#create)
on each proposal. This will create three distinct budgets, rather than updating
the same budget three times.

### Terminate account budgets

Account budgets can be ended while active, and removed entirely prior to
starting or while pending approval.

#### End the active account budget

The active account budget cannot be removed. However, you can set the end time
to the current time. The simplest way to achieve this is to send a proposal with
[`AccountBudgetProposalType.END`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalTypeEnum.AccountBudgetProposalType#end).

The following snippet demonstrates how to end an existing account budget.
Java

```
AccountBudgetProposal proposal = AccountBudgetProposal.newBuilder()
  .setProposalType(AccountBudgetProposalType.END)
  .setAccountBudget(accountBudget.getResourceName())
  .build();

AccountBudgetProposalOperation operation = AccountBudgetProposalOperation.newBuilder()
  .setCreate(proposal)
  .build();

// Send request to Google Ads API (not shown).
```
C#

```
AccountBudgetProposal proposal = new AccountBudgetProposal()
{
  ProposalType = AccountBudgetProposalType.End,
  AccountBudget = accountBudget.ResourceName
};

AccountBudgetProposalOperation operation = new AccountBudgetProposalOperation()
{
  Create = proposal
};

// Send request to Google Ads API (not shown).
```
PHP

```
$accountBudgetProposal = new AccountBudgetProposal([
  'proposal_type' => AccountBudgetProposalType::END,
  'account_budget' => $accountBudget->getResourceName()
]);

$accountBudgetProposalOperation = new AccountBudgetProposalOperation();
$accountBudgetProposalOperation->setCreate($accountBudgetProposal);

// Send request to Google Ads API (not shown).
```
Python

```
account_budget_proposal_operation = client.get_type('AccountBudgetProposalOperation')
proposal = account_budget_proposal_operation.create
proposal.proposal_type = client.get_type('AccountBudgetProposalTypeEnum').AccountBudgetProposalType.END
proposal.account_budget = account_budget.resource_name

# Send request to Google Ads API (not shown).
```
Ruby

```
operation = client.operation.create_resource.account_budget_proposal do |proposal|
  proposal.proposal_type = :END
  proposal.account_budget = account_budget.resource_name
end

# Send request to Google Ads API (not shown).
```
Perl

```
my $account_budget_proposal =
  Google::Ads::GoogleAds::V26::Resources::AccountBudgetProposal->new({
    proposalType => END,
    accountBudget => $account_budget->{resourceName}
  });

my $account_budget_proposal_operation =
  Google::Ads::GoogleAds::V26::Services::AccountBudgetProposalService::AccountBudgetProposalOperation
    ->new({create => $account_budget_proposal});

# Send request to Google Ads API (not shown).
```

This is equivalent to updating an account budget by setting the end
date time to [`TimeType.NOW`](https://developers.google.com/google-ads/api/reference/rpc/v26/TimeTypeEnum.TimeType).

#### Remove an approved account budget before its start time

If you proposed an account budget to start in the future, you can remove it
entirely prior to the start time by sending an
[`AccountBudgetProposalType.REMOVE`](https://developers.google.com/google-ads/api/reference/rpc/v26/AccountBudgetProposalTypeEnum.AccountBudgetProposalType#remove)
proposal type.

The following snippet demonstrates the removal of an existing future account
budget.
Java

```
AccountBudgetProposal proposal = AccountBudgetProposal.newBuilder()
  .setProposalType(AccountBudgetProposalType.REMOVE)
  .setAccountBudget(accountBudget.getResourceName())
  .build();

AccountBudgetProposalOperation operation = AccountBudgetProposalOperation.newBuilder()
  .setCreate(proposal)
  .build();

// Send request to Google Ads API (not shown).
```
C#

```
AccountBudgetProposal proposal = new AccountBudgetProposal()
{
  ProposalType = AccountBudgetProposalType.Remove,
  AccountBudget = accountBudget.ResourceName
};

AccountBudgetProposalOperation operation = new AccountBudgetProposalOperation()
{
  Create = proposal
};

// Send request to Google Ads API (not shown).
```
PHP

```
$accountBudgetProposal = new AccountBudgetProposal([
  'proposal_type' => AccountBudgetProposalType::REMOVE,
  'account_budget' => $accountBudget->getResourceName()
]);

$accountBudgetProposalOperation = new AccountBudgetProposalOperation();
$accountBudgetProposalOperation->setCreate($accountBudgetProposal);

// Send request to Google Ads API (not shown).
```
Python

```
account_budget_proposal_operation = client.get_type('AccountBudgetProposalOperation')
proposal = account_budget_proposal_operation.create
proposal.proposal_type = client.get_type('AccountBudgetProposalTypeEnum').AccountBudgetProposalType.REMOVE
proposal.account_budget = account_budget.resource_name

# Send request to Google Ads API (not shown).
```
Ruby

```
operation = client.operation.create_resource.account_budget_proposal do |proposal|
  proposal.proposal_type = :REMOVE
  proposal.account_budget = account_budget.resource_name
end

# Send request to Google Ads API (not shown).
```
Perl

```
my $account_budget_proposal =
  Google::Ads::GoogleAds::V26::Resources::AccountBudgetProposal->new({
    proposalType => REMOVE,
    accountBudget => $account_budget->{resourceName}
  });

my $account_budget_proposal_operation =
  Google::Ads::GoogleAds::V26::Services::AccountBudgetProposalService::AccountBudgetProposalOperation
    ->new({create => $account_budget_proposal});
