+# Opt-Out management overview
+The Opt-Out Management API enables Azure Communication Services customers 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. The responses are stored and 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](https://learn.microsoft.com/en-us/azure/communication-services/concepts/sms/sms-faq#how-does-azure-communication-services-handle-opt-outs-for-short-codes.md) page. 
+
+## Opt-Out management API
+We are extending opt-out management by enabling ACS customers to manage the Opt-Out database via an API. This API provide the ability to add, remove, or check opt-out entries, effectively overriding the automatic management.
+Key features included:
+
+- **Maintaining an Opt-Out List:** The API maintains a centralized list of opt-out requests, enabling businesses to easily add, remove, and check for individuals who have opted 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 should be sent to individuals who have opted out.
