# `VALIDATION_FAILED` The request is invalid

Source: https://checkslip.com/en/problems/validation-failed

- **HTTP status**: `400`
- **Credit**: No credit taken

## Meaning

The body, query or path does not match the API. Unreadable JSON, a missing required field, or a value of the wrong type or format.

## Fix

Read `errors[]`. Its `pointer` (RFC 6901) names the field and `code` the reason. Fix it and send again (resending unchanged gives the same result).
