Production

All API requests should be made to this base URL. Use your live API key (sk_live_...) for production requests.

Test

Authentication

Include your API key in the Authorization header as a Bearer token with the format: Authorization: Bearer sk_test_1a2b3c4d5e6f

API Key Types:

• Test keys (sk_test_...) - For development and testing, won't process real charges

• Live keys (sk_live_...) - For production use, processes real transactions

Best Practices:

• Never share your API keys publicly or commit them to version control

• Use environment variables to store keys securely

• Rotate your keys regularly

• Use test keys during development and integration

Keep your API keys secure. Anyone with your live key can process payments on your account.
