Implement [FossaPay operation] in [language/framework].

Use this documentation as the source of truth:
- [link to concept or guide]
- [link to endpoint reference]

Requirements:
- Keep x-api-key and webhook secrets server-side.
- Use https://api-production.fossapay.com/api/v1.
- Parse the standard status/statusCode/message/data envelope.
- Preserve decimal precision for money and token values.
- Treat processing states as non-terminal.
- Reconcile ambiguous writes before retrying.
- Do not invent fields, endpoints, statuses, or rate limits.
