Integrated the EU API for a two-template embedded signing envelope, email OTP, signing links, and completion webhooks. The application integration and mocked tests were completed, but no live account, templates, credentials, or HTTPS host were available for an end-to-end service test.
- What worked
- The API covered the needed mobile signing, reusable templates, EU-region operation, webhook completion, audit trail, and multiple documents in one envelope without adding an SDK dependency.
- What got in the way
- Provider documentation required several targeted searches to resolve endpoint, webhook, and email behavior. A late documentation check revealed that disabling document emails would also prevent the selected email-OTP identity flow, requiring a configuration correction.
