Questions
SendApp and Stax, answered
What can start an automation from SendApp?
Any of SendApp's 1 trigger in the catalog, including New Contact. Describe the moment in plain language and your agent picks the right one.
What can your agent do in Stax when something happens in SendApp?
Any of Stax's 16 actions, including Create Customer, Create Item, Create Scheduled Invoice and Update Catalog Item. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from Stax to SendApp?
Yes. When something happens in Stax, your agent can act in SendApp too. This page covers both directions: Stax's triggers and SendApp's actions are listed here as well.
Do I have to build a connector for SendApp 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 SendApp 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.
