How to connect.
-
Open your project, or start a new one from the dashboard.
-
Open the workspace menu and choose Connectors, then pick GatewayAPI.
-
Paste the keys and save. Your preview restarts, and your app can use the service from then on.
Then ask for the feature
- “Text a delivery update to each customer”
- “Send an SMS code at sign-in”
What happens to your keys.
- Each key is saved as a private setting of your project, under the name shown above.
- The AI that builds your app sees only the names. It writes code that reads each key by name, and never the value.
- The values reach your preview and your published app, and never the chat, the code or the logs.
- Open Connectors in your project to replace a key or disconnect the service. Publish again so your live app uses the change.
Service names and logos belong to their owners; Crisp is not affiliated with them. A service changes its keys and pages now and then. Found something out of date? Tell us and we will correct it.
Ask for the feature, and Crisp builds it with GatewayAPI.
