# 70002: Bad request

Log Level: ERROR

## Description

Twilio could not parse the request because the request body or parameters are not in the expected format. This error usually occurs when you send malformed JSON, provide a value with the wrong data type, or submit a request that does not match the API's expected schema.

### Possible causes

* The request body contains invalid JSON
* A parameter value uses the wrong data type, such as sending a string where an integer is required
* The request includes malformed or unsupported parameter formatting
* The request body does not match the expected structure for the API endpoint
* The `Content-Type` header does not match the payload format you sent

### Possible solutions

* Validate the request body before you send it and make sure the JSON is well formed
* Confirm that every parameter uses the expected type and format for the endpoint you are calling
* Review the endpoint documentation and make sure the request body matches the required schema
* Verify that the `Content-Type` header matches the payload format, such as `application/json` for JSON requests
* Log the outgoing request in your application so you can inspect the exact payload and headers being sent
* If you build the request manually, use an official Twilio helper library when possible to reduce formatting errors
