Connect D4Sign to your tables.

Documents, signers and signature status (API v1). In AITIZER, D4Sign becomes an action column: map a few cells to the request, and every row can call it. Manually, on a schedule, when a row changes, or through an AI agent.

What you can automate with D4Sign

How it works

Add the credential once

Paste your D4Sign key in Special Fields. It is encrypted and stays on the server.

Map cells to the request

Pick a D4Sign endpoint for a column and link each placeholder to a column of your table.

Run it any way you like

Per row, on all rows, when a row changes, every night, or as a tool for an AI agent on web, WhatsApp or Telegram.

Prompts you can paste into the composer

Add a column that validates each row with D4Sign
Enrich every new contact with D4Sign data automatically
Build a data-quality dashboard powered by D4Sign

The Vibe Coding composer creates the tables, the D4Sign column, the screens and the login. You keep the code and your data exports anytime.

Frequently asked questions

Do I need a D4Sign developer account?

You need D4Sign credentials (an API key or token) from your own D4Sign account. Paste them once in AITIZER; they are encrypted and injected server-side, never exposed to the browser.

Can an AI agent use D4Sign?

Yes. Any Special Field request can be given to an AI agent as a tool. The agent decides when to call D4Sign, with the permissions you set per table.

What does a D4Sign integration cost on AITIZER?

Integrations are included in every plan, including Free (2 Special Fields) and Starter and up (unlimited). You only pay D4Sign for its own usage.
