The Opt-Out Management API enables you to manage opt-out requests for SMS messages. It provides a self-service platform for businesses to handle opt-out requests, ensuring compliance with regulations and protecting customer privacy. Currently, opt-out handling includes configuring responses to mandatory opt-out keywords, such as STOP/START/HELP and others. The responses to these keywords are stored as part of program/campaign brief. The list of opted-out numbers is maintained in the Azure Communication Services Opt-Out database. This database management is automatic. The Opt-Out database contains entries added when a recipient sends an opt-out keyword. An entry includes the fields: Sender, Recipient, and Country. If a recipient opts back in, the corresponding entry is deleted. To learn more about how opt-out is handled at Azure Communication Services, read our FAQ page.

Opt-Out management API

We're extending opt-out management by enabling you to manage the Opt-Out database via an API. This API allows adding, removing, or checking opt-out entries, overriding the automatic management. Key features include:

• Maintaining an Opt-Out List: The API maintains a centralized list of opt-out requests, enabling businesses to easily add, remove, and check individuals opting out of SMS communications.
• Enforcing Opt-Out Preferences: The API integrates with the opt-out list to ensure that preferences are respected. No SMS messages will be delivered to individuals who opt out.
