## What to do if your operation isn't supported

If this node doesn't support the operation you want to do, you can use the [HTTP Request node](/integrations/builtin/core-nodes/n8n-nodes-base.httprequest.md) to call the service's API.

You can use the credential you created for this service in the HTTP Request node:

1. In the HTTP Request node, select **Authentication** > **Predefined Credential Type**.
2. Select the service you want to connect to.
3. Select your credential.

Refer to [Custom API operations](/integrations/builtin/custom-api-actions-for-existing-nodes.md) for more information.
