## Send your first API call

<Steps>
  <Step title="Set a permission group">
    Define which vaults and operations the API key can access. See [Permission groups](/knowledge-base/platform/developers/permission-groups).
  </Step>

  <Step title="Create an API key">
    Generate a key assigned to the permission group. See [API keys](/knowledge-base/platform/developers/api-keys).
  </Step>

  <Step title="Sign your requests">
    Sensitive endpoints require an Ed25519 signature in addition to the API key. See [Request signing](/knowledge-base/platform/developers/request-signing).
  </Step>

  <Step title="Send the request">
    Include your API key in the `Api-Access-Key` header on every request. Add `Api-Signature` and `Api-Timestamp` on sensitive endpoints.

    ```bash theme={null}
    curl -X GET \
      'https://api.anchorage-staging.com/v2/apikey' \
      -H 'Api-Access-Key: <YOUR_API_KEY>' \
      -H 'Api-Signature: <YOUR_API_SIGNATURE>' \
      -H 'Api-Timestamp: <SOME_TIMESTAMP>'
    ```
  </Step>
</Steps>
