Integrations

Plays nicely with everything.

Your CRM starts the contract, MySign gets it signed, and the sealed copy files itself back where it belongs. Connect the tools your business already runs on, including your AI assistant.

The stack

Your tools, already covered.

Documents flow in from the systems where work starts, and signed copies flow back to the systems where records live. Nobody re-keys anything.

CRM & practice management

A deal moves stage, the contract goes out. When it's signed, the record updates itself.

Salesforce HubSpot Clio

Accounts & finance

Approvals signed and statuses updated without anyone leaving the ledger.

Xero Sage QuickBooks

Storage & documents

Completed documents and their audit certificates file themselves in the right folder.

SharePoint Google Drive NetDocuments

Chat & notifications

A message the moment something's signed. No inbox-refreshing required.

Slack Teams

And everything in between.

Zapier bridges MySign to thousands more apps, and webhooks let you wire up anything with an HTTP endpoint.

AI · MCP server

Enterprise

Your AI assistant can handle the paperwork.

Connect Claude, Copilot or any MCP-compatible assistant to MySign through our Model Context Protocol server. Ask for a contract in plain English. Your AI fills the template, addresses the envelope and reports back when it's signed, while you get on with real work.

  • Assistants act through API keys you issue, and revoke
  • Every envelope keeps its full audit trail, whoever sent it
  • Included in the Enterprise plan, alongside the API

For developers

One API. Every workflow.

No proprietary connectors, no waiting-list roadmap. An open REST API and webhooks that work today, so any integration you can describe is one you can build.

01

Trigger from any tool

An API call creates the envelope, from your CRM, your practice system or a Zap. Documents in, on demand.

02

MySign does the chasing

Routed to the right signatories, tracked in real time, reminders sent automatically, with the full audit trail maintained throughout.

03

The signed copy comes home

Completion webhooks push the sealed document and its certificate back to your systems. Filed, recorded, next step triggered.
