Add specific Stripe customers to corresponding Mailer Lite group

Hi,

I would like to create an automation where if someone buys a specific product of mine using a Stripe payment link, it automatically adds them to a corresponding MailerLite Group.

I’m having trouble creating the correct module for stripe. Every time I try to run a test, the data doesn’t go through to make.com to move it to the second module (mailerlite).

Any advice would be appreciated!

Thank you,
Becca
