Pabbly Subscription Billing Webhook is not working correctly with MailerLite


Your Task History ID
Hi! I hope you are great.

I am experiencing some issues in my workflow: When a successful payment is made on PSB for a specific Plan, the customer's email is added in a specific group on MailerLite.
Everything is working on the tests made on Pabbly Connect interface. But when I try to made more tests creating new test sales on my product. There is an error that occurs. I share my webhook URL: https://connect.pabbly.com/workflow/sendwebhookdata/IjU3NjUwNTZlMDYzZjA0MzA1MjY1NTUzNTUxM2Ei_pc
And I attach some images that reflect better this situation.

And here there are more details about the failed intents:

Can you please tell me what to do?

Hi @alexco888,

By using the 'Mailerlite: Search Subscriber' action event, I can see that you don't have any subscribers in Mailerlite with this email address. Since this subscriber is not present in your Mailerlite account, it cannot be assigned to a group.

I suggest using the 'MailerLite: Create Or Update Subscriber' action event as the second step of your workflow. This will help you create a subscriber in Mailerlite using the details captured from the PSB trigger response, which you can then assign to a group in the third step.
