Hello everyone,

I'm facing an issue while trying to connect my LinkedIn developer app to Odoo (Social Marketing module).

-I have already successfully connected Facebook and YouTube — they are working perfectly.

-My LinkedIn developer app is verified with a company page.

-OAuth2 credentials (Client ID, Secret) are correctly configured.

-The required API permissions have been requested and approved.

-The redirect URI is set (although I’m not 100% sure if it’s completely correct).

-I tested the LinkedIn OAuth2 flow manually with Postman, and it worked correctly, meaning I was able to get the access token without issues.

However, when I try to connect LinkedIn, I first get the "Bummer, something went wrong" message, and then it redirects to an error:

"An error occurred while trying to link your account. LinkedIn did not provide a valid access token."

📌 Extra note:

• Instagram integration also shows small issues.
• X (Twitter) integration has problems too, but I'm focusing on LinkedIn first.

Does anyone know what could be causing this?

Is it a permission scope issue? a redirect URI mismatch? something with LinkedIn's app review?

Any guidance would be appreciated!

Thanks a lot!
