# API Key Settings

> Create, copy, and revoke credentials for programmatic trading through the Funding Perpetuals REST API.

[Open API Key settings](https://fundingperpetuals.com/settings?section=api-keys)

## Create a key

Enter a recognizable name, then select **Create API Key**. Copy the secret when
it appears. Funding Perpetuals stores only its cryptographic hash, so the full
key cannot be shown again.

Each key has read and trading access to every challenge account you own. You
can hold up to five active keys. Use separate names for separate trading
clients so you can revoke one integration without interrupting another.

<Warning>
  Store API keys like passwords. Never commit one, print it in logs, include it
  in a URL, or embed it in browser or mobile application code.
</Warning>

## Revoke a key

Select **Revoke**, review the confirmation, then select **Revoke API Key**.
New requests using that key stop authenticating immediately. A request already
in flight may still finish.

For request examples, authentication rules, and endpoint schemas, read the
[developer API quickstart](/quickstart).
