Questions
openHandwerk and PostStack, answered
What can start an automation from openHandwerk?
Any of openHandwerk's 4 triggers in the catalog, including New Appointment, New Calendar Category, New Customer and New Project. Describe the moment in plain language and your agent picks the right one.
What can your agent do in PostStack when something happens in openHandwerk?
Any of PostStack's 31 actions, including Send an email, Send broadcast, Send emails in batch and Update a contact. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from PostStack to openHandwerk?
Yes. When something happens in PostStack, your agent can act in openHandwerk too. This page covers both directions: PostStack's triggers and openHandwerk's actions are listed here as well.
Do I have to build a connector for openHandwerk or PostStack?
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 openHandwerk and PostStack 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.
