Multiple Actions for Custom Phone and Email Provider Triggers

We are deprecating the ability to create more than one action per tenant for actions supporting custom phone or email providers and introducing a maximum limit of one action in the respective triggers:

• custom-phone-provider
• custom-email-provider

This limitation applies to the Management API create an action endpoint (POST - /api/v2/actions/actions) and can impact integrations performing direct API calls and tools like the Auth0 Deploy CLI, the Auth0 Terraform Provider, or the Auth0 CLI.

We have provided additional information and timelines for enforcing this change across tenants through a dashboard and support center notification.
