## Which one, for what

### Docusign (B)

Good for: Teams whose company already uses Docusign and needs an agent to send envelopes from templates, embed signing and track status with a full audit trail.

Ahead on:
- Payments & pricing, 30 against 25

Watch for: health.docusign.com lists 34 incidents since 9 July 2026, including a two-hour NA4 disruption on 30 July and email notification failures from 25 to 30 September

### Dropbox Sign (B)

Good for: An agent that sends a prepared PDF or a saved template for signature from one company account and tracks it to completion by webhook or polling, with the signed PDF and audit trail at the end.

Ahead on:
- Reliability, 75 against 57
- Schema & documentation, 88 against 70

Watch for: No idempotency keys found in the docs or the spec, so a retried send can create a second signature request

## Verdicts

**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.

**Dropbox Sign.** A public OpenAPI 3.0.3 spec, llms.txt, six official SDKs and a free test mode let an agent build the whole flow before paying. Production sends need a paid plan from $900 a year, the API key has full account access, and no idempotency keys were found in the reviewed documentation.

## Before you call either

### 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

### Dropbox Sign

1. Send `test_mode=true` while building. Test requests are free, watermarked and not legally binding, and are limited to 10 requests a minute
2. Don't blind-retry a send after a timeout. No idempotency key exists, so list requests by `metadata` or title first to check whether it was created
3. Authenticate with HTTP Basic, the API key as username and an empty password. Keep the key out of URLs, although the docs show that form
4. Answer every webhook with HTTP 200 and the body `Hello API Event Received`, and verify `event_hash`. Ten consecutive failures clear the callback URL
5. Treat a 200 from cancel as queued only. Confirmation arrives later as a `signature_request_canceled` event
