correct authentication is 

Hello, i’m trying to do like the example here : https://developers.klaviyo.com/en/reference/create_profile

But i always get a 401 even if i send my authorization like above. See my screenshot

Hi @bproulx!

There’s essentially 3 likely causes of this issue, if you are certain the authentication statement is correctly formatted:

1. There’s a typo in the private API key.
2. The API key does not have the correct scope. (for example, READ permissions is not sufficient to create a profile)
3. If you are trying to make a server-side request (like Create Profile) on the client-side, which would elicit a CORS error. For client-side requests, you could use this endpoint instead:
   • Create Client Profile

Best,
