# 19024: Invalid channel input

Log Type: APPLICATION

Log Level: ERROR

## Description

The request body for a Conversations API operation contains an invalid `channel` value or is missing required channel-related input. Twilio could not process the request because the submitted parameters do not match the expected format or allowed values.

### Possible causes

* The request is missing a required field for the channel you are trying to create or configure
* The `channel` value is invalid for the Conversations resource you are using
* A channel-specific field contains an invalid value or format
* The request includes duplicate parameters or conflicting channel configuration
* The request body structure does not match the expected Conversations API schema

### Possible solutions

* Review the request body and confirm that all required parameters are present
* Verify that the `channel` value is supported for the Conversations API resource you are calling
* Check each channel-related parameter for valid formatting, spelling, and accepted values
* Remove any duplicate fields or conflicting channel configuration from the request
* Compare your request against the Conversations API reference and update the payload before retrying
