What to Do If You Get a 400 Session Invalid Error

Seeing a 400 Session Invalid error when trying to connect to the Hummingbirds platform? No worries — this usually points to a temporary Meta (Instagram/Facebook) issue and can typically be fixed in just a few steps.

1. Log out of Instagram on your device.

2. Log back in to Instagram.

3. Go to your Instagram settings and remove Hummingbirds from your Websites & Permissions.

   • You can find this under: Settings > Security > Apps and Websites

4. Log out of Instagram again.

5. Return to the Hummingbirds platform and try reconnecting your Instagram account.

We know it’s a bit of a process, but the good news is: you should only need to do this once.
