This error comes from Concur and can be due to several reasons i.e:
Concur is sending creates for duplicate profiles
There is an outage on Concur's side
Missing permissions on client Concur site
Ensure that all required permissions are present in the client Concur site. The TMC must set a user with Web Services Administrator permission on the site. This permission needs to be assigned directly to the user and not by groups.
Request XML dumps from Umbrella support to deliver to Concur ( or ask support if they can see the cause of the error based on the XML)
Try manually resaving the profile in Faces after some time to see if the profile is pushed through
HTTP/1.1 403 Forbidden
There is something wrong with the credentials like refresh token or Config ID
Please check the refresh token and ConfigID on the company side
