DocuSign alternative with a compatible API
Docuflex is an original e-signature implementation built to be a drop-in-shaped alternative for teams that already think in DocuSign eSignature terms. The concepts, the lifecycle and the API ergonomics line up, so a migration is mostly renaming the base URL and the auth header.
Docuflex is not affiliated with, endorsed by, or derived from DocuSign, Inc. This page describes functional equivalence only; it makes no claims about DocuSign's current features or pricing.

Concept map
| If your integration uses | In Docuflex |
|---|---|
| Envelope | Envelope (same name, same draft/sent/completed/voided lifecycle) |
| Recipients with routingOrder | Recipients with routingOrder; nine types including signer, cc, certified delivery, in-person signer, agent, editor, intermediary, notary, witness |
| Tabs (signHereTabs, dateSignedTabs, textTabs ...) | Tabs with a type field: signature, initial, date_signed, text, checkbox, radio_group, dropdown, ssn, attachment and more; coordinates as page fractions |
| Templates | Templates with roles and tabs, instantiated into envelopes |
| Bulk send | Bulk send lists and batches |
| Connect | Connect: HMAC-SHA256 signed webhooks with retries, delivery log and replay |
| Embedded signing (recipient view, clientUserId) | POST .../envelopes/{id}/views/recipient with clientUserId; short-lived URL |
| JWT grant | OAuth2 jwt-bearer grant with the same shape; plus authorization-code with PKCE and plain API keys |
| Certificate of Completion | Certificate of Completion PDF plus a machine-readable JSON summary and a public /verify endpoint |
| Idempotency / pagination | Idempotency-Key on every POST and PUT; offset and cursor pagination |
What is different
- Tab coordinates are fractions of the page (0 to 1) rather than points, so they are resolution-independent.
- Every error has one envelope shape with a requestId; every response carries rate-limit headers.
- Audit events are hash-chained and append-only, enforced by database triggers; integrity can be re-verified by anyone with the envelope id, without trusting a PDF viewer.
- Notary, clickwrap, web forms and workflows exist as feature-flagged scaffolds and are off in production today.
Migration checklist
- Create an account at docuflex.net/sign-up and an API key (or register an OAuth client and use the jwt-bearer grant).
- Point your client at
https://api.docuflex.net/v1/accounts/{accountId}and sendx-api-key. - Convert tab positions to page fractions. Keep
documentIndex/recipientIndexsemantics. - Re-create templates and Connect configurations; verify webhook signatures with HMAC-SHA256.
- Run the quickstart in the API reference against one real document and confirm with
GET /v1/verify/{envelopeId}.
