Connect FreeAgent to Retell AI
When New Bank Transaction fires in FreeAgent, your agent runs Add Agent in Retell AI. 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 FreeAgent and Retell AI to do together?

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
FreeAgent and Retell AI, answered
What can start an automation from FreeAgent?
Any of FreeAgent's 6 triggers in the catalog, including New Bank Transaction, New Contact, New Invoice and New or Updated Contact. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Retell AI when something happens in FreeAgent?
Any of Retell AI's 27 actions, including Create Knowledge Base, Create Retell LLM, Update Agent and Update Call. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Retell AI to FreeAgent?
Retell AI has no triggers in the catalog today, so automations start in FreeAgent. If you need the other direction, ask: your agent reads Retell AI's API documentation and adds it.
Do I have to build a connector for FreeAgent or Retell AI?
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 FreeAgent and Retell AI 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.
