In this tutorial you will learn how to get an Instagram session ID, which is required to automatically import Instagram user posts into WordPress by means of the CyberSEO Pro plugin. The process will be demonstrated for Chrome browser, which is the most popular one today. Actually almost the same procedure will work for Firefox and other similar browsers.
First of all make sure you are logged in to an Instagram account.
Now open Instagram in Chrome and click Ctrl+Shift+I to open the Developer Tools and navigate to the “Application” (“Storage” in Firefox) tab. There you will see your Instagram session ID. Double click on it and copy its value.
Now simply paste it into the “Instagram session ID” box on the CyberSEO Pro “Accounts” page.
Save the changes and you are set to go. The only thing you need is to add a new Instagram user channel to CyberSEO Pro, just add its regular URL the same way you syndicate RSS feeds. E.g. https://www.instagram.com/hbo/
Your session ID will be valid for all the time you are logged into Instagram, so don’t logout. If you don’t want to use your personal Instagram account for these purposes, just register a new dedicated one.
