Can I see requests and responses in various cases?
Yes. The API docs have an Examples section with real request/response pairs:
- Standard SCT.
- SCT Inst.
- SDD CORE FRST.
- SDD CORE RCUR.
- SDD B2B.
- Errors (400, 401, 422, 429, 5xx).
- Webhooks.
Each example comes with the equivalent curl and Python/Node snippet.
Conclusion
To handle edge cases, copy the example closest to yours and adapt.
