On the 29th of June 2020, Instagram deprecated the last of its current Instagram API endpoints that 3rd party applications have been using to display photos from Instagram.
This means that any application that has not switched to the new API will no longer have access to display Instagram photos and will most likely display the error message from Instagram: "This endpoint has been retired".
At SnapWidget we switched over to the new API at the beginning of 2020 and fully support both personal and business Instagram accounts.
To switch over to SnapWidget, follow our detailed guide on creating your Instagram widget, and then install it on your site.
