You can use the Merchant Accounts API to programmatically create and manage merchant accounts, users and sub-accounts.
If you're a third-party provider, you can use the Merchant Accounts API to create an interface where merchants can sign up and manage their account information.
Get started
To get started, create your first merchant account.
To verify if your merchant account is ready to use with the Merchant API, see Verify your account's connection to Merchant API.
For more information about the Merchant Accounts API, see the Account reference documentation.
