When connecting your Instagram account, make sure to use your Instagram login details.
Do not use your Facebook login.
💡 Important: you must have a Professional or Business Instgram account. Personal Instagram accounts cannot connect to 3rd party apps.
Connecting Multiple Instagram Accounts
You do not need a separate Blotato account for each Instagram account -- connect them all under one Blotato login.
Click Login with Instagram in Settings. On the Instagram consent screen, click the three dots (···) in the top right corner, then choose Switch account to log into the other Instagram account and connect it. The new account is added alongside your existing one -- it does not replace it.
If Instagram keeps logging into your first account instead of switching, use an incognito window: log out of both Instagram and Facebook, open an incognito window, log into only the second Instagram account, then log into Blotato and click Reconnect. See the general Connecting Multiple Accounts Per Platform guide for details.
If Meta says the Your activity off Meta technologies setting is missing, follow Activity from Other Businesses connection steps, then reset and relink Instagram in Blotato.
Error: 400 Session Error Connecting Instagram Account
IMPORTANT: Sometimes, your IG account connected successfully even though you see the 400 error. Before attempting solutions below, check if you can make a test Instagram post.
Fix #1:
Open incognito Chrome browser
Log out of all other Instagram accounts
Log into the 1 Instagram account you want to connect
Then log into Blotato
Reconnect your account
Fix #2:
I've seen some people fix this by simply waiting a few hours and connecting again. This means it's an Instagram issue, and there's not much I can do on the Blotato side.
Fix #3: If above doesn't work, go to Instagram settings > connected apps > remove Blotato > connect again. Fix #4:
Finally, if all else fails, one last thing is make sure in Instagram settings:
Settings > Sharing and Reuse > Allow People to Share Externally > Website Embeds is toggled on.
Error: HTTP 500 When Connecting Additional Instagram Accounts
If your first Instagram account connects but each additional account fails with "HTTP ERROR 500" right after you log into Instagram, that error page comes from Instagram's own servers, not Blotato. Instagram could not finish the authorization step, so the first account went through and the rest did not.
Fix:
Log out of both Instagram and Facebook completely, not only Instagram. Instagram authorizes through Facebook, so a stale Facebook session blocks the next connection.
Open an incognito Chrome window.
Log into only the one Instagram account you want to add.
Then log into Blotato and click Reconnect.
Connect your accounts one at a time, waiting a moment between each.
This is an Instagram-side error, so waiting a few hours and retrying also resolves it in many cases.
Error: Account Isn't Eligible When Connecting Instagram
If you switched to a Professional or Business Instagram account but still get an "account isn't eligible" error when you try to connect, reauthorize Instagram and remove the "messaging" permission on the consent screen.
Go to Settings > Social Accounts and click Reconnect on Instagram.
On the Instagram permissions screen, uncheck the messaging permission.
Leave the rest of the permissions checked and finish connecting.
This unblocks publishing, but it also turns off every messaging feature on the account:
Reading and sending Instagram DMs. See Messages API.
Private replies to comments.
DM automations, including any automation already live on the account.
Instagram usually reports "account isn't eligible" while the switch to a Professional or Business account is still settling. Wait 24 hours, then reconnect with the messaging permission checked to restore those features.
Error: "The session has been invalidated because the user changed their password"
If a post fails with "Could not publish on Instagram: Error validating access token: The session has been invalidated because the user changed their password or Facebook has changed the session for security reasons", the Instagram access token expired. This comes from Instagram/Meta, not Blotato. It happens when you changed your Instagram or Facebook password, or when Meta ended the session for security (a new-device login, a suspicious login, or pending terms).
Fix:
Go to Settings > Social Accounts and click Reconnect on Instagram.
Log into the Instagram account you want and finish the consent screen.
The new token replaces the invalidated one, and posting works again.
Instagram Auto-Share to Facebook
If you have Instagram's built-in setting enabled to auto-share posts to Facebook, that setting still works when posting through Blotato. Blotato posts to your Instagram account via the Instagram API, and Instagram applies its own crossposting rules the same as any other post.
