Connect Act-On to OnceOnly
When New Contact fires in Act-On, your agent runs Add event in 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.
Build solutions, not workarounds.
What do you want Act-On and OnceOnly 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
Act-On and OnceOnly, answered
What can start an automation from Act-On?
Any of Act-On's 2 triggers in the catalog, including New Contact and New or Updated Contact. Describe the moment in plain language and your agent picks the right one.
What can your agent do in OnceOnly when something happens in Act-On?
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 Act-On?
OnceOnly has no triggers in the catalog today, so automations start in Act-On. 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 Act-On 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 Act-On 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.
