Klaviyo api trouble with api connector (works fine in postman)

Hello.
I’m having trouble running this one POST call to Klaviyo api with JSON body. All other calls without a body works fine. Also this post call works fine in postman.

POST https://a.klaviyo.com/api/v2/list/{LIST_ID}/subscribe
parameter: api_key: pk_4f9d94c6e2f07f40754fa53613yy17953e

JSON Body object
{
“profiles”: [
{
“email”: “george.washington@example.com
}
]
}

Hi @niklasf I’m experiencing the same issue. Did you ever solve this?

Hello! Yes, i solved it.

The API key should be directly in the url.

As so: https://a.klaviyo.com/api/v2/list/yourlistid/subscribe?api_key=pk_12938812983891284578
