Use a Straddle SDK to call the API from your application. Choose your language, install the package, and follow its client setup example.

​
Install your SDK

Each language reference covers request methods, response types, authentication, and error handling.
Install the package for a TypeScript or JavaScript application:
Open the TypeScript setup guide or API reference.

​
Configure your application

Load your sandbox API key in your backend process and pass it to the SDK client. Set the API base URL to https://sandbox.straddle.com. The setup guide for each language shows the client options and supported environment variables. For SaaS and marketplace integrations, include the account context required by each operation. See the account-scope table for the Straddle-Account-Id rules.

​
Build with your coding agent

The Straddle integration workflow helps your coding agent choose an SDK, implement your payment flow, and test it in sandbox. For an existing integration, choose a task from the skill catalog.
