D4Sign API: documents, signers and e-signature with AI agents
The D4Sign API lets you upload documents, build the list of signers, send for signature and track status, with a legally valid audit trail. D4Sign is a Brazilian e-signature service, used by companies in Brazil for sales contracts, hiring and terms. Access is through a token and a cryptographic key generated in the dashboard, with a test environment.

What an iTeam agent does with the D4Sign API
Service contract
The agent generates the contract from the template with CRM data and sends it to the customer after legal approves.
Digital onboarding
The HR agent sends the hiring documents and reminds the candidate until the signature is complete.
Pending-items board
The agent lists documents waiting for signature for more than a few days and alerts the owner.
Archiving
When a document is complete, the agent downloads the signed file and records it in the ERP or the customer folder.

iTeam vault

Questions about the D4Sign API
Is the D4Sign API free?
It depends on the plan. API access and document volume are tied to the D4Sign plan, so check the current terms.
Do I need to code to use the D4Sign API with iTeam?
Not necessarily. iTeam's HTTP tool reads the API documentation and learns the endpoints, and the deployment team sets up credentials, permissions and tests with you.
Does the D4Sign API have a webhook?
Yes. You can register a URL to receive document event alerts, such as a completed signature, and the agent continues the process from there.
