Connect FreshBooks to Newton
When New Bill fires in FreshBooks, your agent runs Compute absolute value in Newton. 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.

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
FreshBooks and Newton, answered
What can start an automation from FreshBooks?
Any of FreshBooks's 16 triggers in the catalog, including New Bill, New Client, New Credit Note and New Estimate. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Newton when something happens in FreshBooks?
Any of Newton's 15 actions, including Compute absolute value, Compute area under curve, Compute cosine and Compute inverse cosine. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Newton to FreshBooks?
Newton has no triggers in the catalog today, so automations start in FreshBooks. If you need the other direction, ask: your agent reads Newton's API documentation and adds it.
Do I have to build a connector for FreshBooks or Newton?
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 FreshBooks and Newton 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.
