Questions

What can the AI do in Firma.dev?

The AI can list and read signing requests, templates and workspaces, including recipients, fields, audit trails and signed documents. It can create templates from a PDF or DOCX, update and duplicate them, create and send signing requests, edit unsent ones, resend signing emails and cancel requests.

Does the AI see my Firma.dev API key?

No. Your Firma.dev API key is encrypted at rest and never shown to the AI. After you save it, it is not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with tracking only. Sending and resending emails signers, and cancelling a request cannot be undone, so those tools can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Firma.dev account.

Can I test without sending real documents?

Yes. Your Firma.dev dashboard has a live key and a test key. The test key creates watermarked test documents and uses no credits, so you can try the connection first and switch to the live key later.
