**Requirements:** a Stripe account (section 2). 1. Go to the Stripe **Dashboard** and open **Developers → API keys** (`dashboard.stripe.com/test/apikeys` in test mode). 2. Click **Create restricted key**. 3. You can start from a preconfigured permission set or start with none — choose to start with none so you give only the three minimum permissions. 4. Give it a recognizable name in the **Key name** field. 5. Mark exactly these three permissions — no more: | Resource | Permission | What the connector uses it for | | --- | --- | --- | | Payment Links | Write | Generating and cancelling the payment link ("Generate a payment link"/"Cancel a payment link" actions). | | Checkout Sessions | Read | Checking a payment's status ("Check a payment's status"). | | Webhook Endpoints | Write | Registering the automatic notice that confirms when a payment resolves (panel action from section 5). | 1. Click **Create key** and complete the two-factor verification Stripe sends you. 2. Click the key value to copy it — Stripe only shows it in full this first time. Verified against Stripe's official documentation (`docs.stripe.com/keys` and `docs.stripe.com/keys/restricted-api-keys`, checked on September 5, 2026).
