Questions
Stripe and EchtPost Postcards, answered
Can a postcard be sent automatically when someone pays in Stripe?
EchtPost Postcards lists actions for creating a contact, reading a contact and checking your credit balance, so the Stripe payment can create or look up the recipient. The card itself is still sent from EchtPost once the contact is in place.
What if the Stripe customer has no address on file?
The agent can read the full record with Get Customer first and only create the EchtPost Postcards contact when an address is present. It tests every scenario, including customers with a missing address, before the setup runs on live payments.
What can start an automation from Stripe?
Any of Stripe's 11 triggers in the catalog, including New Customer, New Invoice, New paid charge and New Refund. Describe the moment in plain language and your agent picks the right one.
What can your agent do in EchtPost Postcards when something happens in Stripe?
Any of EchtPost Postcards's 3 actions, including Create Contact, Get Balance and Get Contact. Your agent maps the data both ways and tests every scenario before it ships.
Can it also run from EchtPost Postcards to Stripe?

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.
What happens when something fails?

Is there a free plan?
Yes. Every plan includes the agent, including free, and building from your own AI client spends no assistant credits.
