We received the “[IMMEDIATE ACTION REQUIRED] Breaking Retell AI API change” email about deprecated Phone Number API fields. The email says log analysis indicated recent use of deprecated APIs by our organization, but doesn’t specify which calls or agents are affected.

We’ve audited our codebase and [Make.com](http://Make.com) integrations and can’t identify which API calls are using the deprecated fields. We also have the Apr 3 model deprecation coming and want to make sure we’re not running any of those either.

Could someone from the Retell team check our account and tell us specifically which API calls, agents, or phone numbers are flagged? That would let us fix the right thing instead of guessing.

Thank you for your reply. We have reviewed the provided documentation, but we are still unable to pinpoint the specific deprecated API calls within our account. The email we received indicates usage, but without further details, we’re unable to identify and rectify the issue. Could you provide guidance on which API calls, agents, or phone numbers are flagged for deprecation so we can address them?

Hi @retellai

I checked with our team, and it looks like this change is being rolled back. There’s no action required from your side at the moment.

Best regards
