# invalid_request

**HTTP status:** 400 (Bad request)

**Title:** Invalid request

## Cause

A field of the request is missing, has the wrong type or breaks a limit, or the body has a field that does not exist. The `param` of the answer names the first field that failed and the `detail` says which rule it broke.

## How to fix it

Correct the field named in `param` as the detail says, then send the request again.

Set the parameter named below and send the request again.

Every error carries `requestId` and the `Request-Id` header. Send it when you write to support.
