 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.

 ## 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.

-Sending an Opt-out API request is similar to SMS as described in the [Azure Communication Services Postman Tutorial](https://learn.microsoft.com/azure/communication-services/tutorials/postman-tutorial) with the difference of endpoints for OptOut Actions (Add, Remove, or Check) and body.
