# Connect Relatel to OnceOnly

When **New Call** fires in [Relatel](https://apiant.ai/connections/relatel), your agent runs **Add event** in [OnceOnly](https://apiant.ai/connections/onceonly). 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 Relatel and OnceOnly 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.

Questions

## Relatel and OnceOnly, answered

###

Any of Relatel's 4 triggers in the catalog, including New Call, New message, New Smiley and New voicemail. Describe the moment in plain language and your agent picks the right one.

###

### What can your agent do in OnceOnly when something happens in Relatel?

Any of OnceOnly's 11 actions, including Add event, Add policy, Add tool and Check & Lock. Your agent maps the data both ways and tests every scenario before it ships.

###

### Can it also run from OnceOnly to Relatel?

OnceOnly has no triggers in the catalog today, so automations start in Relatel. If you need the other direction, ask: your agent reads OnceOnly's API documentation and adds it.

###

### Do I have to build a connector for Relatel or OnceOnly?

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 Relatel and OnceOnly 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.
