Unable to add members to LIST through API using Go

Hi @ragch577,

Thanks for sharing this with our community.

First, can you ensure you are using your private API key for this request?

Also, make sure that you're specifying the content type in your API call. If you're sending Klaviyo data, this will be a POST request. Also, please ensure that you are specifying the payload as JSON in the header.

Here's an example curl request using the V2 Lists API members endpoint:

curl -X POST \
  https://a.klaviyo.com/api/v2/list/LISTID/members \
  -H 'Content-Type: application/json' \
  -d '{
 "api_key": "private_key",
 "profiles": [
  {

      "email":"testing@yahoo.com"



  }

 ]

}'

If you’re still having trouble, can you send over the full payload (redacting all sensitive information including your API key, email address and phone number) and any additional errors you are seeing?
