Trying the sample application from this article link and I'm getting the error - "invalid client credentials". Tested everything with Postman and all looks good, however, I noticed in the apigee trace that it is sending client_secret= (with no value). Checked the zip file in the article and I didn't see where I'm suggesting this int he XML ;(
Any ideas? On Salesforce if I pass the client secret all works and if I pass not client secret or just client_secret= I get the same error. Not sure how I can fix this - do I have control over this?
Seems like an issue on Salesforce - grant_type=password shouldn't require a client_secret I believe...
Thanks!
