Using secret key

To configure this credential, you'll need:

• A Host

• A Secret Key

The credential connects to your project using the Supabase Data API, which must be enabled. You can check and enable it in your project's Data API settings.

To generate your secret key:

1. In your Supabase account, go to the Dashboard and create or select a project for which you want to create an API key.

2. Go to Integrations > Data API and copy the Project URL. Enter it as your n8n Host, omitting the /rest/v1 path at the end (use https://your_project.supabase.co, not https://your_project.supabase.co/rest/v1).

3. Go to Project Settings > API Keys to see the API keys for your project.

4. Create or reveal a secret key and enter it as your n8n Secret Key. Refer to Understanding API keys for more information.

Existing credentials that use a legacy service_role secret keep working, but Supabase is phasing out legacy API keys. Replace the legacy secret with a new secret key before legacy keys are disabled at the end of 2026.
