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.

If the error persists or you need help along the way, please reach out to the Hummingbirds HQ team. We’re happy to help and really appreciate your patience! 💛
