Setup guide (opens in a new tab)Documenso handles the signing and Resend handles the email. Joining them means every point in a document's life, created, opened, signed, rejected or cancelled, can drive what happens in Resend: a contact created, a segment updated, a scheduled email cancelled or a message sent to the right person. The agent builds the flow, tests every scenario and keeps it running.

- Verify Domain
Asks Resend to re-check the DNS records for one of your sending domains and start verifying it. Verification runs in the background, so the domain shows as pending until it finishes.
No trigger or action matches that. Ask your agent to add it: it reads the API documentation and builds what you describe.

Questions
Documenso and Resend, answered
Can the flow check whether a signer is already in Resend before adding them?
Yes. The agent can retrieve the contact in Resend first and only create a new one when nothing comes back, then add that contact to the segment you name.
Does this work in both directions?
No. Documenso provides the triggers, such as a document being completed, rejected or cancelled, and Resend provides the actions, such as sending an email or updating a contact. Nothing flows from Resend back into Documenso.
What can start an automation from Documenso?
Any of Documenso's 7 triggers in the catalog, including Document Cancelled, Document Completed, Document Opened and Document Rejected. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Resend when something happens in Documenso?
Any of Resend's 28 actions, including Cancel Email, Remove Contact From Segment, Retrieve Contact and Send Batch Emails. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Resend to Documenso?
Resend has no triggers in the catalog today, so automations start in Documenso. If you need the other direction, ask: your agent reads Resend's API documentation and adds it.
Do I have to build a connector for Documenso or Resend?
No. Both are in the catalog with their triggers and actions. You describe the automation; your agent builds it, tests every scenario and keeps it running.
Can my AI client use Documenso and Resend without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in Resend once and it runs that action on the spot. Ask for an automation and your agent builds it, tests every scenario and keeps it running. One connection covers both.
What happens when something fails?
Your agent works that out for you. It plans the failure paths along with the happy path, then tests every scenario before it ships.
Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
