# Revocation status

Credentials can be revoked or unrevoked, and as such they contain a revocation status so that verifiers/issuers can check if the credential is still valid. Once a revocation registry has been created and credentials issued with it, you can check the revocation status. Verifiers will do this automatically.

## Get revocation status

To check if an id is revoked or not, you can check its status with the registry id (`regId`) and revocation id (`revId`).

### Parameters <a href="#get-revocation-status-parameters" id="get-revocation-status-parameters"></a>

<table data-full-width="false"><thead><tr><th width="118">Name</th><th width="106">In</th><th width="117">Type</th><th width="130">Required</th><th>Description</th></tr></thead><tbody><tr><td>regId</td><td>path</td><td><a href="https://github.com/docknetwork/knowledgebase-docs/blob/main/developer-documentation/dock-api/index.html.md#schemahex32">Hex32</a></td><td>true</td><td>Revocation registry id.</td></tr><tr><td>revId</td><td>path</td><td><a href="https://github.com/docknetwork/knowledgebase-docs/blob/main/developer-documentation/dock-api/index.html.md#schemahex32">Hex32</a></td><td>true</td><td>Credential revocation id.</td></tr></tbody></table>

## Get revocation status witness

The accumulator witness is utilized by the holder to generate a proof, which combines the witness with their revocation id associated with the credential id (`revId`) and the accumulator associated with the registry id (`regId`), allowing the verifier to validate the credential's status without directly accessing the revocation id on the blockchain.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.truvera.io/truvera-api/revocation-status.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
