A new charge, customer, subscription or refund in Stripe can record a purchase event in LettrLabs or add the buyer to your address book, and Stripe lookups let you fill in the customer name and address first.

No, LettrLabs only offers actions here, so every scenario begins with a Stripe trigger such as New Charge, New Customer, New Subscription or New Refund. From there the agent runs LettrLabs actions like Send Purchase Event or Add Address Book Entry. ### ### How does the buyer's address reach LettrLabs? Stripe triggers often carry only an ID, so the agent uses Get Customer, Get Charge or Find Customer by Email to pull the name, email and address on file. Those details are then passed into Add Address Book Entry or Send Purchase Event. ### ### 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 LettrLabs when something happens in Stripe? Any of LettrLabs's 5 actions, including Add Address Book Entry, Delete Conversion, List Conversions and Send Purchase Event. Your agent maps the data both ways and tests every scenario before it ships. ### ### Can it also run from LettrLabs to Stripe? LettrLabs has no triggers in the catalog today, so automations start in Stripe. If you need the other direction, ask: your agent reads LettrLabs's API documentation and adds it. ### ### Do I have to build a connector for Stripe or LettrLabs? 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 Stripe and LettrLabs 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.
