In my sample data I’m using an email address that is associated with a customer, but I also tried using a known email address associated with an existing customer. In both cases the test is saying “Nothing could be found for the search.”
I tried the “Help me fix it,” option which seems to have some information that I can’t see (or it is making things up?) but either way, Zapier says it is sending information in the query and Stripe is not finding that information. What am I missing here?
Hi
Welcome to the Community.
If Zapier can't find a customer in Stripe, ensure the email format is correct and try a different email tied to an active Stripe customer. Verify the customer's status in Stripe and reconnect your Stripe account to Zapier if needed. Also, ensure sample data matches a Stripe customer during testing.
Let us know if you have further questions.
Hi
Try testing with the Zap turned ON, then check your Zap Runs history details to see the DATA IN/OUT for each step to help you trace and troubleshoot: https://zapier.com/app/history/
Post screenshots of the Zap Runs data if you need more help.
