Need to add new users to list, API doku very weak on list usage explaination

Question

Greetings.First off, it’s hard to get an account started here, if you’re developer for a company that does not want you to use the main account (which I can totally understand, honestly). Ok so I need to add email / firstname / lastname / phone / country to a list automatically when the user stated to opt in to newsletter / ads per mail/phone in a thírd party shop. I keep getting stuck in the API documentation and clues that I find on the internet simply don’t seem to work. I search for existing profiles:Response: {"detail":"There is no profile matching the given parameters"}None found, I’d need to make one most likely. (how?) My best bet: send it straight forward to the list api / members api / …Response: {"detail":"profiles is a required parameter."}Note: It’s absolutely set, I even get that message when I POST the ORIGINAL example data. This is kinda mudfart as it ruins my entire weekend with the kids. Please help me, thanks!!!

I got it to work. I suspect a misstake in the headers I previously sent with cURL.Also Api v1 used base64 encoded data which I had hardcoded in the sender

Hello @JunkMedia,Thanks for sharing your feedback with the Klaviyo Community!I think it would be really helpful if you could share the calls you’re making to better see what the issue may be.To add contacts to a Klaviyo list via Klaviyo’s API, you’ll want to be hitting the subscribe endpoint as explainedin theSubscribe Profiles to Listas part of the List API. In addition, if you were actually trying to redirect customers from an existing signup form to a Klaviyo list, you can actually set up a redirect as explained in theHow toRedirectExistingSignupFormsto KlaviyoHelp Center article.I hope this helps!David
