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.

Docusign

The eSignature REST API has public Swagger and OpenAPI files on GitHub, OAuth 2.0, a free developer sandbox and Connect webhooks, and the MCP server reached general availability on 30 September 2026. Production needs a paid plan from $50 a month and a Go-Live review, and the status site lists 34 incidents since 9 July 2026.

Before you call either

Adobe Acrobat Sign

  1. Call the base URI endpoint first and cache api_access_point. Each account lives on one shard such as api.na1.adobesign.com, and other hosts answer INVALID_API_ACCESS_POINT
  2. Request only the scopes the task needs, with the :self modifier. :account lets the token act for every user in the account
  3. On 429 wait the seconds in Retry-After or retryAfter. Retrying sooner resets the timer on accounts created after 20 May 2025
  4. Don't poll. An identical GET repeated past the plan's threshold returns 429. Subscribe to webhooks, or send If-None-Match with the ETag
  5. Create agreements in DRAFT state, check them, then move to IN_PROCESS. No idempotency key exists, so check before re-sending a failed POST /agreements

Docusign

  1. Call /oauth/userinfo once after sign-in, cache base_uri and the account ID, and send every eSignature call to that host under /restapi/v2.1
  2. Create and send an envelope in one Envelopes:create call with status set to sent. Docusign asks for five calls or fewer per envelope
  3. Subscribe to Connect or set eventNotification for status. Polling one envelope more than once every 15 minutes is flagged and can fail the Go-Live review
  4. Set transactionId on envelope creation so a retry after a lost response can find the envelope. The ID is valid for seven days
  5. Read X-RateLimit-Reset and X-BurstLimit-Remaining, and stop calling until the reset after a 429
