What can your agent do in US Global Mail when something happens in Square?
Any of US Global Mail's 16 actions, including Update folder, Update mail item, Add address and Add folder. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from US Global Mail to Square?
Yes. When something happens in US Global Mail, your agent can act in Square too. This page covers both directions: US Global Mail's triggers and Square's actions are listed here as well.
Do I have to build a connector for Square or US Global Mail?
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 Square and US Global Mail 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.
