Posting to Instagram requires the use of the GAIN Notify app. This companion app is required to seamlessly post content directly to Instagram with just a tap when content is scheduled. Instagram does not offer a sanctioned API that allows GAIN to automatically publish content. So, the GAIN Notify app alerts you when it's time to post content and allows you to post with just a few taps directly from your iPhone.
Important: an Instagram post will not show up on the app until it's time to publish the post, per the publish date you set. So, a post is scheduled for tomorrow at 10 am, it will only show up on the app at that hour and not before.
A post showing up on GAIN Notify does not depend on a previous post being published or not, it only depends on the scheduled date/time.
Setting up the Gain Notify App to Receive Notifications
To download the app go to the App Store and type GAIN Notify.
Login to your GAIN account using your credentials.
Note: GAIN Notify supports 1Password manager to log in to the app.
After you're signed-in, allow GAIN Notify to push notifications, otherwise, you will not be notified when new content is ready to be published, by selecting OK. Then it will want to confirm again so select Allow.
Pending and Posted tabs
If no posts ready to publish are available, the empty Pending tab will read: "No posts ready to publish. Login to your GAIN account and get notifications when there's Instagram to publish."
When content is available they will be on this tab waiting to be manually posted. (See below image).
The Posted tab will include all the content that you've already posted to Instagram.
Time to post
When it's time to post, you will receive a push notification on your phone and an e-mail reminder. Make sure to allow push notifications for GAIN Notify app on your phone.
