# Invalid content digest

- **Code:** `invalid_content_digest`
- **Status:** 400
- **If this was an order:** This request bought nothing
- **Send it again unchanged?** No — change something first
- **.NET SDK:** `AnisApiException`

## What it means

Reserved. Anis does not send this code today: a body that does not match its `Content-Digest` is answered `invalid_credentials`.

## What to do

- Handle it like [`invalid_credentials`](https://developers.anis.ly/errors/invalid-credentials.md) if you ever receive it.
- Compute the digest over the exact bytes you send, and check that no proxy re-encodes request bodies.

## Example

The body of the refusal. Its `type` is the address of this page.
