social_post_instagram
Social Post Instagram is a expansion of the Social Post Module. It provides the logic to publish content on Instagram via the Instagram Graph API and the module View Bulk Operations
What you need for the module to work:
A working Meta app where you configure Settings and Configurations for 'Facebook login for Business'
For more information: https://www.drupal.org/project/social_post_facebook
A private/keys dictionary, where a instagram.key file is stored.
A Facebook Site where your instagram account is linked to.
Once that is all setup, you can go to your site, go to configuration, Social API settings and Autoposting settings. You should see the social_post_instagram module.
Now click the 'Instagram' tab.
There you should be able to configure you Instagram App settings.
When you are finished you can navigate to Sitewide Account and add your Instagram Account.
Everything is setup now.
You can now use our build in "Post To Instagram" Action via the module View Bulk Operations
With that you are able to select which Picture/Pictures you want to post.
