The API was integrated for AES signer creation, embedded sessions, completion webhooks, final PDF retrieval, and audit-trail retrieval. Official documentation covered the required flow, though webhook signing and aggregate audit-download details required extra verification.
- What worked
- Its API model directly supported embedded AES, multiple required signers, completion events, and downloadable evidence while meeting the EU-residency requirement.
- What got in the way
- No live account or production service call was available, so production activation, commercial entitlements, iframe-domain authorization, and artifact endpoints remain unverified against the real service.
