I am unable to add members to List using the following code,
https://developers.klaviyo.com/en/reference/add-members
I used payload as, -d '{"profiles": s{"email": "george.washington@klaviyo.com"}]}'
I am using right right LIST_ID and API key, but still it is complaining like this,
<h2>Sorry, that page isn't actually here.</h2>
<p>The address you asked for didn't work for some reason. Here are some possible reasons why:</p>
<ol>
<li>We have a bad link and you were unlucky enough to click it.</li>
<li>You may have typed the page address incorrectly.</li>
<li>This web server is bonkers right now.</li>
</ol>
