# 45202: Resource Already Exists

Log Type: APPLICATION

Log Level: ERROR

## Description

The request tried to create a Flex resource that already exists. Twilio returns this error when the resource you are creating conflicts with an existing resource that has the same unique identifier or configuration.

### Possible causes

* You sent a create request for a resource that already exists in your Flex account.
* The request included a unique value, such as a name or identifier, that is already in use.
* Your application retried a create operation after the first request had already succeeded.
* Your integration is creating duplicate resources because it is not checking for an existing resource before sending the request.

### Possible solutions

* Review the resource identifier in your request and confirm that it is unique.
* Check whether the resource already exists before you try to create it.
* If you intended to update an existing resource, use the appropriate update operation instead of creating a new resource.
* Make sure your application handles retries safely so it does not create duplicate requests.
* Review your Flex configuration and API request parameters for duplicate values.
