Integration
Connect eSignatures and Stax
When Contract Signed fires in eSignatures, your agent runs Create Customer in Stax, or List Payment in Stax 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 Stax 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
Claude Code
Run this in the directory you want to work in.

Paste the address where the client asks for a remote MCP server URL, and name the server apiant-ai where it lets you. APIANT's skills reach the client over the same connection.

Questions
eSignatures and Stax, 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Any of eSignatures's 4 triggers in the catalog, including Contract Signed, Contract Withdrawn, Signer Declined Signature and Signer Viewed Contract.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 Stax when something happens in eSignatures?
Any of Stax's 17 actions, including Create Customer, Create Item, Create Scheduled Invoice and Update customer. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Stax to eSignatures?
Yes. When something happens in Stax, your agent can act in eSignatures too. This page covers both directions: Stax's triggers and eSignatures's actions are listed here as well.
Do I have to build a connector for eSignatures or Stax?
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 Stax 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.
