Integration
Connect Harvest and Sender
When New Client fires in Harvest, your agent runs Unsubscribe Email in Sender, or New Group in Sender to Create Contact in Harvest. 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 Harvest and Sender 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
Harvest and Sender, answered
What can start an automation from Harvest?
Any of Harvest's 16 triggers in the catalog, including New Client, New Contact, New Expense and New Invoice. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Sender when something happens in Harvest?
Any of Sender's 10 actions, including Create Campaign, Add group, Add Subscriber to Group and Add / Update Subscriber. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Sender to Harvest?
Yes. When something happens in Sender, your agent can act in Harvest too. This page covers both directions: Sender's triggers and Harvest's actions are listed here as well.
Do I have to build a connector for Harvest or Sender?
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 Harvest and Sender 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.
