How do I connect Facebook and Instagram to the Social inbox?

In Marketing > Social inbox create your gym's Meta app, save its App ID and Secret, then press Connect Facebook and choose your Page. Instagram comes with it.

Where: Marketing > Social inbox

Who can do this: Owners

The Social inbox brings the comments on your Facebook Page and Instagram into one place. Connecting takes a one-time setup.

Before you begin

The Social inbox must be switched on for your gym by NinjaHQ.
An owner does the connecting. You need the Facebook account that is an admin of your gym's Facebook Page.
Your Instagram should be a professional account linked to the Page.

Steps

Open Social inbox. Under 1. Your gym's Meta app, open How to create it.
Go to developers.facebook.com/apps and sign in with the Facebook account that is an admin of your Page. First time: press Get started to register as a developer (it is free).
Press Create app. Name it something like "Your Gym Social Inbox" and choose the use case Manage everything on your Page.
In the app add Facebook Login for Business (or Facebook Login) and Instagram.
Under Facebook Login > Settings, paste the address shown in the steps into Valid OAuth Redirect URIs and save.
Under App roles > Roles, add every person who will press Connect as an Administrator or Tester. Leave the app in Development mode.
Under App settings > Basic, copy the App ID and App secret into the boxes on the Social inbox page and press Save. The secret is like a password: never email or post it.
Under 2. Connect your accounts press Connect Facebook (or Connect Instagram). One Facebook sign-in connects both. Choose your gym's Page and its Instagram account when Facebook asks.
If you have more than one Page, pick Which Page is your gym and press Use this Page.

What you'll see

Your comments appear on the Comments tab within a few minutes. Connected accounts are listed at the top with when they were last checked.

If Facebook ends the connection (a password change, or its periodic security check), a red notice appears with Connect Facebook again. A weekly email also reminds the owner.

Troubleshooting

"Facebook didn't finish connecting". Check the redirect address, and that you are an Administrator or Tester of the app.

"That Facebook account doesn't manage any Pages". Sign in with a Page admin and tick the Page and its Instagram when Facebook asks.

No Instagram came with the Page. Link your professional Instagram account to the Page, then connect again and tick Instagram.

To disconnect. Open Connection at the bottom and press Disconnect. Old comments stay.

Questions

I do not see Social inbox in my menu.

It is switched on for each gym by NinjaHQ. If the page says it is not switched on for your gym yet, ask NinjaHQ.

Why does it ask me to create an app?

Facebook and Instagram let a business read and answer comments only through an app registered with Meta. Until NinjaHQ's own app is approved by Meta, your gym uses its own. It takes about ten minutes, once.

Does my Instagram need to be special?

It must be a professional account (Business or Creator) linked to your Facebook Page.
