Hello,
You used the wrong URL. Here is the valid instruction: https://xtemos.com/docs/basel/faq-guides-2/setup-instagram-api/
Our Instagram WPBakery element has two options to get media from your account on Instagram:
Scrape – simply scrapes the page on the web and parses all the images. This method is outdated and may be blocked by Instagram now.
AJAX – similar to the first one but images are parsed on the frontend side. Works for now but probably will not be allowed in the future.
We are releasing a new update soon and add the features with the recent version and update the documentation accordingly.
Best Regards
