I have an approved Advertising API inside my Linkedin App so the "r_basicprofile", "r_1st_connections_size" scopes are granted.
I am looking for the number of the connections of the user which based on the document could be get via /rest/connections/{id} endpoint.
When I get the access token ( put it in the header of the get request) then I want to reach https://api.linkedin.com/rest/connections/{id}{I think id of the inkedin user and can be retrieve via r_basicprofile} I get the following error:
{"message":"Key parameter value 'XXXXXX' is invalid","status":400}
Where I assumed the id can get via r_basicprofile is "XXXXXX" which it looks it is not right. Anyone knows what I need to replace for {id}?
According to the LinkedIn documentation, you don't need to specify a user id in the call. Instead, just use an access token that was granted by the user whose connections you want to query (e.g. for the user with id 'XXXXXX').
