A naming error was identified in the BudgetPerDayMinimumErrorDetails message of V21 of the Google Ads API, where the field minimum_budget_amount_micros was incorrectly labeled as minimum_bugdet_amount_micros. This mistake has been rectified in V22, and a retroactive correction for V21 will take effect on October 15th, 2025, coinciding with the V22 release.
For users of the officially supported client libraries, the transition will be seamless, but an upgrade will require code modifications to reflect the corrected field name. Users employing the Google Ads API with the REST transport layer must ensure their code references the field correctly. For further inquiries, users can connect via the Google Advertising and Measurement Community Discord server.
