Verify your account's connection to Merchant API

If you have an existing merchant account, you can use the API explorer in the reference documentation to verify that your account is ready to use with the Merchant API.

1. Find your merchant-ID in the top of Google Merchant Center.
2. In the API Explorer for the accounts.products.regionalInventories.list method, do the following:
   1. Enter your merchant ID in the merchantId field.
   2. In the Credentials section, select Google OAuth 2.0 and API key.
   3. Click Execute.
   4. If prompted, sign in with the Google Account associated with your Google Merchant Center account.

If your merchant account is set up correctly, the request succeeds and returns an HTTP response code 200. If you just created a new account, the accounts.products.regionalInventories.list method doesn't return any products.

Next, use a client library to request access to other merchant accounts, or use a service account to authorize API access to your own account.
