# Connect HelloSign and Mailjet

When **New Signature Request** fires in [HelloSign](https://apiant.ai/connections/hellosign), your agent runs **Remove Contact from List** in [Mailjet](https://apiant.ai/connections/mailjet), or **New Contact** in Mailjet to **Get Signature Request Files** in HelloSign. Describe the whole flow and it is built, tested on every scenario and kept running.

What the catalog holds today. Ask for anything missing and your agent reads the API documentation and adds it.

## What do you want HelloSign and Mailjet to do together?

Give your AI client this address.

`https://mcp.apiant.ai`

One connection does both: ask your client to act in an app once, or have it build an automation that keeps running. Any client that takes a remote MCP server. Nothing to install. Create your free account, then sign in once in your browser.

### Set it up in your client

### Claude Code

Run this in the directory you want to work in.

`claude mcp add --transport http -s project apiant-ai https://mcp.apiant.ai`

Start Claude Code there, approve the server, and sign in in the browser page it opens.

[Claude Code guide (opens in a new tab)](https://apiant.ai/docs/mcp/claude-code)

### Claude, web and desktop

Open Customize, then Connectors, then Add custom connector, and paste the address. On Team and Enterprise an owner adds it first.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Cursor

Add the address to your MCP configuration as a server URL. Cursor signs you in in your browser.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Zed

Open Settings, then AI, then MCP Servers, then Add Server, then Add Remote Server.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Codex and the ChatGPT desktop app

Open Settings, then MCP servers, then Add server, and choose Streamable HTTP. From the terminal, Codex takes the address with its own add command and then signs you in.

[Setup guide (opens in a new tab)](https://apiant.ai/docs/mcp)

### Any other MCP client

Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.

Mailjet holds your contact lists and sends the mail; Dropbox Sign (HelloSign) handles the paperwork. Joining them means a signature request can create or update the right Mailjet contact and move them between lists, and a contact landing in a Mailjet list can trigger the agreement they need to sign.

Questions

## HelloSign and Mailjet, answered

###

### Can a signer become a Mailjet contact automatically?

Yes. A new signature request in HelloSign can trigger Create Contact in Mailjet, then Add Contact to List and Manage Contact Data to store details like the agreement date. The agent tests every scenario before it goes live, including contacts that already exist.

###

### What can start an automation from HelloSign?

Any of HelloSign's 1 trigger in the catalog, including New Signature Request. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in Mailjet when something happens in HelloSign?

Any of Mailjet's 16 actions, including Remove Contact from List, Create Contact, Create Contact List and Create Contact Property. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can it also run from Mailjet to HelloSign?

Yes. When something happens in Mailjet, your agent can act in HelloSign too. This page covers both directions: Mailjet's triggers and HelloSign's actions are listed here as well.

###

### Do I have to build a connector for HelloSign or Mailjet?

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 HelloSign and Mailjet without building an automation?

Yes. With your AI client connected to APIANT, ask it to do something in either app 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.
