Hey everyone, I’m pretty new to n8n and APIs but I’m trying to automate LinkedIn publishing, however when I try to add LinkedIn credentials, I get this error of the string being too long? I don’t think there’s anything I can change from my side so I’m wondering if anyone knows if this is an existing bug/knows a workaround for this?
32 characters sounds likely.
Are you sure you don’t have a space either on the end or at the start of the secret key?
Yes, and I also found news of LinkedIn increasing their Client Secret to up to 50 characters (LinkedIn Talent Solutions Release Notes - LinkedIn)
I’m also having this issue! Even if I take the first 32 characters, I still get the error message. Must be a bug.
I’m having this issue, too. Definitely a bug…
Hi everyone,
Thanks for bringing this up!
We might not have updated on our end after Linkedin made their changes.
Taking a look and I’ll get back to you on this

Small update:

It’s waiting to be reviewed and should likely be out with the next version

When is the next version going to be released - to latest and the stable release? Wanting to test out LinkedIn functionality and can’t do that until this fix is available.
It will be released on Monday to as the next label it will then become latest / stable the Monday after.
Thank you!

I can confirm that it now works, though you need to ensure you turn off both Organisation Support and Legacy in the LinkedIn credential for it to work for some reason.

It all depends on what you are doing, legacy is for the older LinkedIn app version which is still valid and organisation support is for posting as a business page.
