Sign in to the [Crave Business Manager](https://partners.craveup.com). 2. Open **Settings → Developer → API Keys**. 3. Click **Generate Key**, give it a descriptive name (for example, `storefront-sdk-staging`), and confirm. 4. Copy the key immediately—once you leave the page it cannot be viewed again. Add the key to each request header: ```http GET /merchant/crave-collective Host: api.craveup.com X-API-Key: ``` ### Best practices - Store keys in environment variables or a secrets manager; never commit them to source control. - Use separate keys for staging and production so they can be rotated independently. - If a key is exposed, revoke it from the dashboard and generate a fresh one right away. contact: name: Crave Support email: support@craveup.com servers: -
