We are consuming a REST API from Salesforce and made a HTTP PATCH call from the Integration Server to Salesforce.
However, we observed that Salesforce received a GET request instead of PATCH. On increasing the logging level within IS, we observed that Salesforce initially sent back a HTTP 301 status code and following redirection, the method got changed to GET while making the call to the new URL.
I read on one of the knowledge center articles that this has been handled in IS version 10.0 and up but we are using 10.3 and facing this issue. Does anybody have a solution or workaround for this?
