Connect CallRail to Vapi
When Outbound Call Completed fires in CallRail, your agent runs Create Call in Vapi. 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.
Build solutions, not workarounds.
What do you want CallRail and Vapi to do together?
Ask the assistant
Connect your AI client
Give your AI client this address.
https://mcp.apiant.aiOne 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.

Questions
CallRail and Vapi, answered
What can start an automation from CallRail?
Any of CallRail's 5 triggers in the catalog, including Outbound Call Completed, SMS Received, Form Captured and Phone Call Started. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Vapi when something happens in CallRail?
Any of Vapi's 21 actions, including Create Call, Create Chat, Update Call and Update phone number. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Vapi to CallRail?
Vapi has no triggers in the catalog today, so automations start in CallRail. If you need the other direction, ask: your agent reads Vapi's API documentation and adds it.
Do I have to build a connector for CallRail or Vapi?
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 CallRail and Vapi without building an automation?
Yes. With your AI client connected to APIANT, ask it to do something in Vapi 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.
