# 90037: Broadcast has too many 'CorrelationId' items

Log Type: APPLICATION

Log Level: ERROR

## Description

This error occurs when your Broadcast request includes more `CorrelationId` values than the API accepts.

### Possible causes

* Your request includes too many `CorrelationId` items.
* Your application adds duplicate or repeated `CorrelationId` values to the same Broadcast request.
* Your request-building logic appends `CorrelationId` values in a loop and exceeds the allowed request limit.

### Possible solutions

* Reduce the number of `CorrelationId` values you send in a single Broadcast request.
* Remove duplicate `CorrelationId` entries before you submit the request.
* Split large Broadcast operations into multiple requests so each request stays within the accepted limit.
* Review the code that builds your Broadcast payload and make sure it only adds the `CorrelationId` values you intend to send.
* If you are building a new notifications workflow, use Programmable Messaging for SMS notifications. For push notifications, integrate directly with APNs or FCM. Notify is deprecated.
