Hello, I am trying to subscribe users to a Klaviyo list by sending data to the API via webhook. I think the issue is in the payload, but I’m not sure exactly what it should look like.


I’m fairly confident I have the endpoint right, and I have set this up with other email marketing platforms so I know the source of the webhook works. I’m hoping someone can show me an example or a template of what my payload should look like - it just needs to send first name and email address to the list.

Hello @Alex Tucker , would you like to share the endpoint and payload that you are sending? As well as any error you are getting? You should redact any sensitive data like api keys. We should have working examples for all endpoints in our api docs:
