# Connect HelloSign and OpenAI

When **New Signature Request** fires in [HelloSign](https://apiant.ai/connections/hellosign), your agent runs **Create message** in [OpenAI](https://apiant.ai/connections/openai), or **New file** in OpenAI 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 OpenAI 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.

Connecting OpenAI and HelloSign lets a team put document work and model work on the same track. A new signature request in HelloSign can hand its documents to OpenAI for a written summary, an embedding or a moderation check, and a file uploaded to OpenAI can go straight out for signing in HelloSign.

Questions

## HelloSign and OpenAI, answered

###

### Can the agent read the actual contract text from HelloSign into OpenAI?

HelloSign returns a download URL for the documents of a signature request as a PDF, and that URL is what gets passed on to OpenAI. From there an OpenAI step such as sending the model a message can work with the document content you supply.

###

### Will reminders only go to signers who still have not signed?

Yes, the agent can look up the signature request in HelloSign first and send the reminder only when the request is still pending. It tests every scenario, including a request that is already complete, before the setup goes live.

###

### 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 OpenAI when something happens in HelloSign?

Any of OpenAI's 69 actions, including Content moderation, Create embedding, Create assistant and Create chat completion. Your agent maps the data both ways and tests every scenario before it ships.

###

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

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

###

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

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 OpenAI 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.
