How do you connect an app that has no native integration?
You connect any other app through the BoldSign API. Your developers send documents from code and embed signing in your product. Webhooks report each change to a document.
- Developers
eSignature API
Send, track, and download documents from your own code, with SDKs for .NET, Node.js, Python, Java, and PHP.
See the eSignature API - Developers
Embedded signing
Show the signing page inside your own website or app, so customers sign where they already are.
See embedded signing - AI agents
BoldSign MCP
Connect Claude, ChatGPT, or your own AI agent to prepare and send documents for people to sign.

Why choose BoldSign for connected signing
BoldSign keeps signing inside the tools your team already uses. The full record stays with every signed copy.
-
Signers need nothing new
Signers open the link and sign in any browser, with no BoldSign account or app to install.
-
The record travels with the file
Cloud storage integrations file the audit trail and signer attachments alongside each completed document.
-
Updates arrive as they happen
BoldSign webhooks and Zapier triggers fire as soon as a document changes, so no one has to check.
-
Test before you go live
Build and test API, Zapier, and Power Automate workflows in a free sandbox before real documents go out.
Limits and costs to know before you connect apps to BoldSign
Each BoldSign integration starts on a set plan, and two of them cost extra. Prices are in USD.
| Integration | Plan it starts on | Extra cost |
|---|---|---|
| Xero | Growth plan, $5 per user a month | $5 per organization a month |
| HubSpot | Business plan, $15 per user a month | None |
| Dropbox, Google Drive, and OneDrive | Business plan, $15 per user a month | None |
| Salesforce | Business plan, $15 per user a month | $10 per user a month on the Business plan$21 per organization a month on the Premium plan |
| Zapier and Power Automate | Enterprise API plan, from $30 a month with 40 envelopes | None; $0.75 per envelope after the first 40 |
For HubSpot and cloud storage together, the Business plan covers both with no extra cost.

Questions about eSignature integrations
What is an eSignature integration?
An eSignature integration links a signing tool to another app. Documents then move between them without copy and paste. With BoldSign, you send, track, or store documents from the app you already use. See every BoldSign feature.
Does BoldSign integrate with Microsoft apps?
Yes. BoldSign connects to Power Automate and OneDrive. It also supports single sign-on through Microsoft Entra ID.
Can I send documents for signature from my CRM?
Yes, from Salesforce or HubSpot. You send from a CRM record, fill fields from its data, and see the signing status there. The Salesforce integration shows each step.
Do I need a developer to use these integrations?
No, not for the eight native integrations. You build Zaps and Microsoft flows without writing code. Connecting another app through the BoldSign API needs a developer.
Are documents signed through an integration legally binding?
Yes. Signatures you collect with BoldSign are legally binding under the ESIGN Act, UETA, and eIDAS. That holds whether you send from BoldSign, a CRM, or an automation.
Bring signing into the apps you already use
Start a BoldSign trial, connect your first app, and send a document from it.
