  • Amount, currency, and operation number arrive correctly.

Move to production

After approval, request production credentials and keys. Change the environment script and URLs in a controlled release, keep signature validation enabled, and run a final low-value test.
Do not reuse integration credentials, keys, or URLs in production.
