        content: '<Info>

          * The Cohort Sync API only matches users already present in MoEngage based on the User ID (`uid`) provided in the request. This API does not create new users.

          * This API endpoint does not currently support Team-level scoping. All segments generated using this call will be assigned to the Default Team automatically.

          * Please note that this API does not support updating cohorts created on the dashboard or via [File Segment API](https://www.moengage.com/docs/api/file-segments/create-file-segment).

          </Info>


          #### Rate Limits

          Please adhere to the following limits:

          * **Frequency:** 300 requests per minute.

          * **Payload Structure:** One payload per request (each payload can contain multiple UIDs).

          * **Size Limit:** The payload size cannot exceed **128KB**.


          #### User Resolution

          The Cohort Sync API resolves existing users in MoEngage based on predefined user identifiers:

          * **Identifier:** We primarily rely on the **User ID** (`uid`) provided in the request payload.

          * **Matching:** This must match the Unique User ID set in MoEngage (typically available for registered or logged-in users).

          * **Profile Association:** Each Unique User ID corresponds to a single user profile. Even if a user is logged in across multiple devices, the devices are associated with that single user profile.
