Verdicts
Adobe Acrobat Sign
The REST API has OAuth 2.0 scopes that can be limited to one user, a group or the account, Retry-After on throttled calls and a free Developer Edition. Adobe calls its own SDKs obsolete, the newest dated API change is November 2025, and API plans are sold through sales with no public price.
PandaDoc
The public OpenAPI spec lists 133 operations and reached version 8.21.0 on 2 October 2026, and the hosted MCP server, with OAuth and dynamic client registration, is open to every plan including Free. The status page records three incidents affecting document creation, sending or the API between 15 July and 6 September 2026, and writes have no idempotency keys.
Before you call either
Adobe Acrobat Sign
- Call the base URI endpoint first and cache
api_access_point. Each account lives on one shard such asapi.na1.adobesign.com, and other hosts answerINVALID_API_ACCESS_POINT - Request only the scopes the task needs, with the
:selfmodifier.:accountlets the token act for every user in the account - On 429 wait the seconds in
Retry-AfterorretryAfter. Retrying sooner resets the timer on accounts created after 20 May 2025 - Don't poll. An identical GET repeated past the plan's threshold returns 429. Subscribe to webhooks, or send
If-None-Matchwith the ETag - Create agreements in
DRAFTstate, check them, then move toIN_PROCESS. No idempotency key exists, so check before re-sending a failedPOST /agreements
PandaDoc
- Wait for
document.draftbefore sending. Creation is asynchronous and a new document stays indocument.uploadedfor a few seconds - Match the region. Accounts on app.pandadoc.eu use api.pandadoc.eu and mcp.pandadoc.eu, and the global hosts reject them
- Check for an existing document before retrying a create. There's no idempotency key and each production create uses a usage credit
- Retry 409 after a pause and back off on 429. A sandbox key allows 10 requests a minute per endpoint
- Don't rely on webhooks alone. Failed deliveries aren't retried, so poll the status endpoint as a fallback
