Teams search "pandadoc integration" when they need contracts to move without manual upload loops. Atlas does not ship a marketplace connector for every CRM. The supported pattern is your middleware calling POST /api/envelope plus webhooks back to your stack.
Share: Trigger in your app, review_url for ops, webhook when signed.
Reference flow
- Your integration fires on stage change or form submit
- POST /api/envelope with PDF or DOCX
- Store review_url for human Send (or template auto_send when trusted)
- Verify X-Atlas-Signature on lifecycle webhooks
- Update CRM or billing on envelope.signed
Create example
curl -X POST https://atlaswork.ai/api/envelope \
-H "Authorization: Bearer $ATLAS_API_KEY" \
-H "Content-Type: application/json" \
-H "Idempotency-Key: pandadoc-integration-create" \
-d '{
"document_url": "https://cdn.example.com/order.pdf",
"webhook_url": "https://your-server/webhooks/atlas",
"metadata": {"client_reference_id": "ext-123"},
"parties": [{"email": "signer@example.com", "name": "Signer", "role": "Customer"}]
}'
Pass Idempotency-Key derived from your external record ID so retries do not duplicate envelopes.
Webhook verification
Atlas POSTs lifecycle events with HMAC in X-Atlas-Signature. Verify with your API key before you update downstream systems.
Handle at least envelope.sent, envelope.signed, envelope.voided, and envelope.declined.
Agent alternative
If the caller is Claude, ChatGPT, or Cursor, use Atlas MCP instead of custom middleware for ad-hoc sends.
Production hardening
Always pass Idempotency-Key derived from your external record ID. Retries must not create duplicate envelopes.
Poll fields_status before send on ad-hoc creates. Sending while detection is pending returns 409.
Store envelope_id on your CRM or billing row before you mark the deal as contract sent.
Sequential signing
Atlas signs in order. Multi-party deals need party tokens on each sign URL.
Each signer sees only their fields when tokens are present.
Template branch
When legal trusts a standard order form, save an Atlas template and call POST /api/templates/{id}/send with prefill from PandaDoc properties.
Trusted templates can auto-send. First-time shapes still deserve review_url.
Error handling
402 when credits exhausted. 409 on fields_version mismatch. 400 on malformed parties.
Log envelope_id on every create for support traces.
Staging checklist
- Create with two-page PDF or DOCX
- Open review_url and confirm fields
- Send to a mailbox you control
- Sign on mobile once
- Verify webhook and signed PDF download
Security review questions
Confirm data residency, retention after cancel, and subprocessors on email delivery with your security team.
Redact signer email in production logs if policy requires.
Pilot metrics
Track time from trigger to first signed PDF, webhook latency p95, and support tickets per hundred automated sends.
Five free sends at /signup validate PandaDoc wiring before finance approves paid credits.
Ops handoff
Document which team owns webhook verification, which owns template updates, and which owns signer support during pilot week.
Keep rollback steps in the runbook until three production-like envelopes complete without manual fixes.
When PandaDoc native wins
Keep PandaDoc when sales builds proposals inside PandaDoc daily and finance expects quote analytics there.
Pilot Atlas on one finished-PDF workflow before you rip out PandaDoc seats company-wide.

FAQ
Does Atlas replace native PandaDoc e-sign? Only when your documents are PDF or DOCX from your product and you want usage-priced API sends.
Credits? One per envelope sent. Drafts and detection are free.
PDF and DOCX? Both supported on create.

Middleware pattern
PandaDoc bundles editor, pricing tables, and signing in one UI. Teams search "pandadoc integration" when they already have PDFs in their product and only need the signing step.
Your app owns document generation. Atlas owns detection, review, send, sign, and signed PDF storage.
- CRM stage change triggers middleware.
- POST /api/envelope with document_url and parties.
- Ops reviews fields once per template family.
- Webhook updates CRM on signed.

Templates for repeat PandaDoc shapes
After legal approves a layout in review, save as Atlas template. Repeat sends use POST /api/templates/{id}/send instead of re-uploading editor exports.
Production checklist
Always pass Idempotency-Key on POST /api/envelope. Retries from automation must not duplicate envelopes.
Upload PDF or DOCX via multipart when bytes live on disk. Use document_url when the file sits on object storage.
Poll fields_status before send. Sending while detection is pending returns 409.
Set webhook_url at create. Verify X-Atlas-Signature HMAC with your API key before CRM updates.
Atlas signs in order on multi-party envelopes. Each sign_url needs ?t=<token>. See sequential signing.
OpenAPI: /openapi.json. MCP tools: /mcp. Full REST map: e-signature API.
Error handling
402 when credits exhausted. 409 on version mismatch or send while fields pending. 400 on malformed parties.
Log envelope_id on every create for support traces.
