Hi there,
I need your support due to an error conecting to Send in Blue Platform using the optin-form add-on in my website template. I'm using the Tixon template, and I've already tryed several approaches but it gives always the same error "Some problem occurred, please try again.".
I've followed the steps and filled the API fields and List ID as you can check. Can you please help me on this? Please Check the images in attachment.
Thank you in advance,
Luís Ferreira
