Integration
Connect SendGrid and Stax
When New bounce fires in SendGrid, your agent runs Create Customer in Stax, or List Payment in Stax to Create or update contact in SendGrid. 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
SendGrid and Stax, answered
What can start an automation from SendGrid?
Any of SendGrid's 4 triggers in the catalog, including New bounce, New global suppression, New or updated recipient and New suppressed email. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Stax when something happens in SendGrid?
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 SendGrid?
Yes. When something happens in Stax, your agent can act in SendGrid too. This page covers both directions: Stax's triggers and SendGrid's actions are listed here as well.
Do I have to build a connector for SendGrid 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 SendGrid 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.
