Integration
Connect eSignatures and Harvest
When Contract Signed fires in eSignatures, your agent runs Create Contact in Harvest, or New Client in Harvest to Add Signer in eSignatures. 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 eSignatures and Harvest 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.
Set it up in your client

Questions
eSignatures and Harvest, answered
What can start an automation from eSignatures?
Any of eSignatures's 4 triggers in the catalog, including Contract Signed, Contract Withdrawn, Signer Declined Signature and Signer Viewed Contract. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Harvest when something happens in eSignatures?
Any of Harvest's 12 actions, including Create Client, Create Contact, Create Project and Create Task. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Harvest to eSignatures?
Yes. When something happens in Harvest, your agent can act in eSignatures too. This page covers both directions: Harvest's triggers and eSignatures's actions are listed here as well.
Do I have to build a connector for eSignatures or Harvest?
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 eSignatures and Harvest 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.
