  currency: 'usd',

Best Practices

Keep SDKs updated - We release fixes and new features regularly. Check for updates monthly.
Use server-side SDKs for secrets - Never put your secret API key in frontend code.
Handle errors - Always wrap SDK calls in try/catch and handle errors gracefully.
Use TypeScript types - Our JavaScript SDK includes full TypeScript definitions.
Test in sandbox - Use test API keys during development.

ClapPay CLI

Our command-line tool helps with development and testing:

npm install -g @clappay/cli
