Why is the Instagram integration not working?

​

First, check the connection method

Instagram can be connected using the following two methods. If the connection fails, the items to check differ depending on the chosen method.

1. Log in directly to Instagram (recommended)
   • Requirements: An Instagram professional account (Business or Creator) and permission to access NoimosAI
   • You can use features necessary for daily Instagram operations such as creating and publishing posts, responding to comments and DMs, checking mentions, and insight analysis.
2. Log in via Facebook Page
   • Requirements: An Instagram Business account linked to a Facebook Page, and the necessary permissions for the Facebook profile, Facebook Page, and Instagram business assets
   • If you want to use hashtag search, retrieve information from other professional accounts, or use posts with product tags, log in via the Facebook Page.

An Instagram professional account is an account switched to Business or Creator type. You cannot connect with a personal account, so please switch to a professional account in the Instagram app before connecting. NoimosAI recommends direct login to Instagram because it simplifies connection settings. If you see a Facebook login screen or screens to select Facebook Pages or business assets, you are proceeding with connection via Facebook Page. In that case, please check from the “Checklist for verification via Facebook Page” section on this page.

​

If you cannot log in directly to Instagram

Since direct login to Instagram does not use Facebook Pages or business assets, the following four items should be checked:

1. Confirm in the Instagram app that the target account is Business or Creator.
2. If you are logged into another Instagram account in your browser, log out and log back in with the account you want to connect.
3. Check the access items displayed on the authentication screen and allow access to NoimosAI.
4. Close the authentication screen and retry connecting by logging in directly to Instagram from NoimosAI’s integration screen.

If an error related to Facebook Pages appears, you are starting connection via Facebook Page instead of direct Instagram login. Return to NoimosAI and select the direct Instagram login method.

​

Checklist for verification via Facebook Page

If you connect Instagram via Facebook Page and the account does not appear or cannot connect, please check from the top in order. Even if Facebook integration is complete, it does not necessarily mean the conditions required for Instagram integration are met.

​

Connection procedure via Facebook Page

The Meta authentication screen displayed during Instagram integration varies depending on your Facebook login status and past connection history. Please check the instructions that match the screen displayed. Multiple confirmation screens may appear consecutively.

​

Confirm the state before connection

Confirm that the Instagram account is a Business account and linked to the Facebook Page used in NoimosAI. Also confirm that Allow access to Instagram messages in Inbox is enabled in Facebook Page’s Settings > Linked Accounts > Instagram.

​

Start connection in NoimosAI

Open the Instagram integration screen in the target workspace’s Integrations and select the method to log in via Facebook Page.

​

Confirm the Facebook profile used via Facebook Page

Here, confirm the Facebook profile that grants the Meta permissions required for Instagram integration to NoimosAI. This does not register the Facebook profile itself as the Instagram connection destination.

​

If asked to log in to Facebook or select a profile

If you are not logged into Facebook or multiple profile information remains in the browser, a login or profile selection screen will appear. Log in with or select a profile that has access permissions to the Facebook Page linked to the Instagram account you want to connect. If managed via Business Portfolio, use a profile with access to both the Facebook Page and Instagram account.

​

If “Continue as [Name]” is displayed

If you are logged into Facebook, a screen may appear asking if you want to continue authentication with the current profile. Confirm that the displayed profile has the necessary access permissions and click Continue as [Name]. To use a different profile, click Log in with another account.

Both Facebook login and Continue as [Name] are operations to confirm the profile used. After that, depending on the connection status, a screen to select assets or use previous settings will appear.

​

Check past connection settings via Facebook Page

After confirming the profile, if there are settings previously authorized to NoimosAI remaining in Meta, a screen may appear asking whether to continue using the previous settings.

​

To use the same settings as last time

Click Continue. The range of Facebook Pages, Instagram accounts, and business assets previously authorized to NoimosAI will be reapplied. If you previously authorized multiple pages or Instagram accounts, the entire permission range will be reapplied. It does not automatically select one asset.

​

To review or change authorized assets

Click Edit Settings. You can review and reselect the Facebook Pages, Instagram accounts, and business assets to allow access to NoimosAI.

If you select Continue, previous settings will be reapplied and the screen to select Facebook Pages or Instagram accounts may not appear. If you want to review or change the assets to connect, select Edit Settings.

​

Select assets to authorize to NoimosAI

If connecting for the first time or if you selected Edit Settings on the previous screen, select Instagram accounts, Facebook Pages, and business assets.

1. Click Get Started.

2. Select the Instagram profile you want to connect.

3. If the Instagram screen opens, choose whether to save login information in the browser or not. Selecting either option proceeds to the next screen.

4. Select the Facebook Page to authorize access to NoimosAI.

5. Click Continue to allow access to the selected Facebook business assets.

6. Select the access permissions for the Instagram account and click Continue.

7. Confirm that the target Instagram account, Facebook Page, and business assets are selected, then click Save.

8. Click Done to return to NoimosAI.

Common errors via Facebook Page

​

When “Sorry, something went wrong” is displayed

If the Meta authentication screen shows “Sorry, something went wrong. We’re working to fix it as soon as possible,” an error occurred in Meta’s connection process. This message is not an error from NoimosAI. Common causes include:

• Temporary authentication error on Meta’s side
• Allow access to Instagram messages in Inbox is off on the Facebook Page
• Conflicting Facebook login information or cookies remaining in the browser
• Logged into multiple Facebook accounts simultaneously
• Access permissions for the target page or Business Portfolio assets are not correctly recognized by Meta
• Instagram and Facebook Page were connected just now and the connection status is not yet reflected in screens or authentication
• Past business integration permissions granted to NoimosAI do not match the current page and permission configuration

Please retry in the following order:

1. Open Facebook Page’s Settings > Linked Accounts > Instagram and confirm the target Instagram account is connected and Allow access to Instagram messages in Inbox is on. If off, turn it on and complete any requested access permissions.
2. Close the authentication screen and restart Instagram integration from NoimosAI.
3. If not improved, log out from Facebook and log back in only with the Facebook personal account that has access to the target page.
4. Log into NoimosAI and Facebook in a browser incognito window and retry connection.
5. Check NoimosAI connection in Facebook’s Settings & Privacy > Settings > Business Integrations. If old permissions remain, delete NoimosAI and reconnect, selecting pages and permissions again.
6. If still not resolved, wait 10–30 minutes and try connecting again.

​

When “Invalid request / Invalid redirect URL” is displayed

Even if this message appears on the Meta authentication screen, the cause is not necessarily only NoimosAI’s redirect URL settings. The combination of permissions for Instagram, Facebook Page, Facebook personal account, and Business Portfolio may not be valid on Meta’s side, preventing authentication. First, check the checklist above to confirm the target Instagram is linked to the correct Facebook Page, Allow access to Instagram messages in Inbox is on, and the Facebook personal account used for connection has access to both the page and Instagram. If the error message says “Instagram Business profile linked to Facebook Page not found,” the main causes are:

• Instagram is not linked to the Facebook Page
• The linked Instagram is a personal account
• The link between Instagram and Facebook Page is not yet confirmed on Meta’s side
• Allow access to Instagram messages in Inbox is off

Please check account type, Facebook Page linkage, and pending link confirmation according to the checklist above.

​

If you still cannot connect

If you cannot connect after trying the checks for the selected connection method, please share the following information with support:

• Exact error message
• Team name and workspace name
• Instagram account name
• Selected connection method
• Facebook Page name if connecting via Facebook
• Screenshots of the failed steps
