HEY ! i AM STARTING OUT IN N8N , BUT HAVE BEEN STRUGGLING WITH CREATING CREDENTIALS FOR LINKED IN , i HAVE TRIED SOLVING IT BY READING THROUGH THE DOCS BUT THE LATEST UPDATE WHERE IT DOESN’T TAKE CLIENT id AND SECRET FOR STANDARD CONNECTION IS NOT WORKING FOR ME.
Describe the problem/error/question
I am trying to connect to LinkedIn in and build a post automation , hence using the linked in create a post node. However , when I try to create new credential and connect my account it gives an unauthorized_scope_error.
I have configured my linked in developer API correctly ,
-
Share on Linkedin and Sign In with LinkedIn using OpenID Connect is added
Image -
My Client Secret and Client Id is enabled
-
Redirect Link is added
Image
4) Scope for personal posting also enabled.
Image
Additionally to test if my LinkedIn developer API is setup correctly , I have made a test automation using HTTP request to post in linked in and it is working perfectly to post it , however I am unsure how to attach an image while posting and hence would need the linked in node for that.
I have added the HTTP request workflow in the workflow section.
What is the error message?
Received following query parameters: {“error”:“unauthorized_scope_error”,“error_description”:“Scope “openid” is not authorized for your application”,“state”:“eyJ0b2tlbiI6IkNzMzk3TzUyLXBQZmxCZzRnaEdJRmRVV3JfNmJDV1ZCZVFCdyIsImNpZCI6InRCRHlIaUdmVjlteHhtcUgiLCJjcmVhdGVkQXQiOjE3NjMzNDkxNTczMjMsInVzZXJJZCI6IjhmNGNmODE3LTM5MzctNGZmMS1iNDA2LTI4OTQyYzNiYjk1OSIsImhvc3QiOiJ0Y2FpYXVhZy5hcHAubjhuLmNsb3VkL3Jlc3QifQ==”}
workflow/screenshots/recording
This is a credential creation problem and I do not have a working workflow with link in node , however as mentioned earlier I have built a workflow using HTTP request and here’s that-

Sharing step by step screenshot of trying to enable the linked in credentials.
Step 1 : Create a new linked in node and clicked on create new credentials -
Step 2 : Unchecked Organisational Support and Legacy , clicked on connect an account
Image
Error -
Alternate Step 2 : I have tried keeping Legacy On and the connect my account , then the pop up asks me to login and Allow N8n permissions , on allowing it does show Connection Successfull -
Step 3: Now , the person field should have my name in it but it doesn’t show , so in expression I mentioned the Name and when I put a text and click on execute , I get a 403 error , which n8n suggest is due to credential problem.

End Note
Thanks for looking into this , my understanding is that n8n is picking up the client secret and client id from somewhere , but it’s best if we are able to mention the client id and secret on the standard credentials page so that there is down time when he client id and secret has to be changed.
Suggestions are welcome , if I am doing anything wrong here,
