Questions
PostGrid Print & Mail and 3Dsellers, answered
What can start an automation from PostGrid Print & Mail?
Any of PostGrid Print & Mail's 4 triggers in the catalog, including New Cheque, New Contact, New Letter and New Postcard. Describe the moment in plain language and your agent picks the right one.
What can your agent do in 3Dsellers when something happens in PostGrid Print & Mail?
Any of 3Dsellers's 14 actions, including Create Product, Create Product Category, Update Product and Generate Order Invoice. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from 3Dsellers to PostGrid Print & Mail?
3Dsellers has no triggers in the catalog today, so automations start in PostGrid Print & Mail. If you need the other direction, ask: your agent reads 3Dsellers's API documentation and adds it.
Do I have to build a connector for PostGrid Print & Mail or 3Dsellers?
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 PostGrid Print & Mail and 3Dsellers 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.
