Use Paddle in your Crisp app.
Payments with tax handled by the merchant of record.
Sell one-off products and subscriptions through Paddle checkout, with sales tax and VAT worked out, collected and filed by Paddle. The app can list prices, open checkout, and react when a payment or renewal lands.
What you need.
Create the keys in your Paddle account and paste them in. Each one is saved under the name shown, and your app reads it by that name.

How to connect.

Then ask for the feature

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 Found something out of date?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 Paddle.
