Business Profile API allowlisting & quota issue for automated review replies across 31 GBP locations

Google Cloud Cloud Foundations & Onboarding

Hello everyone,

We manage 31 verified Google Business Profile locations under one organization account for our brand.

We are currently building an internal n8n workflow to automatically manage and reply to customer reviews received daily across our multiple Google Business Profile locations.

Our workflow is intended to:

  • Fetch incoming reviews

  • Organize review activity across all locations

  • Help automate operational review reply workflows for our owned business profiles

While configuring the Google Business Profile APIs, we started receiving this error:

429 - Quota exceeded for quota metric ‘Requests’ and limit ‘Requests per minute’ of service ‘mybusinessaccountmanagement.googleapis.com’

When we checked Google Cloud Console, the quota for “My Business Account Management API” shows 0.

What we have already done:

  1. Enabled the required APIs in Google Cloud

  2. Created OAuth credentials

  3. Built the n8n integration workflow

  4. Submitted a quota increase request

  5. Received a response that quota increase was denied because the Cloud Project is not yet allowlisted

  6. Submitted the official “Application for Basic API Access” form

  7. Received a support case confirmation from Google

One thing that confused us during the API application process:
The form only allowed selecting one business profile, even though our organization manages 31 verified locations under the same brand account.

What we are trying to understand:

  • Is the 429 quota exceeded error expected before allowlisting approval?

  • Does Google review API access at the organization/account level even if only one representative business profile is selected?

  • Is there anything else we should configure or verify while waiting for allowlisting approval?

Important clarification:

  • We are only managing our own verified business locations

  • This is an internal operational workflow

  • We are not building public tools, scraping systems, or unauthorized automation platforms

Any guidance from developers or businesses who have gone through the GBP API allowlisting process for multi-location organizations would be greatly appreciated.

Thank you.
