I'm having a weird issue with an endpoint. This is an existing SS 1.0 endpoint that's been working fine for a couple years, suddenly a few weeks ago it started returning 405 errors, specifically: "Error 405--Method Not Allowed The method specified in the Request-Line is not allowed for the resource identified by the Request-URI. The response MUST include an Allow header containing a list of valid methods for the requested resource." The input into the endpoint hasn't changed, and I'm not sure where I should be specifying the allowed request It's just doing a post of an XML payload that looks like this: '<?xml version="1.0" encoding="utf-8" ?><request type="addTrialSubscription"> <customer internalID=""> <id>74000</id> <firstName>Example</firstName> <lastName>Customer</lastName> <phone></phone> <email>example@customer.net</email> </customer> <item internalID="441"> <leadSource>172343</leadSource> <numOfDays>1</numOfDays> <endDate>7/15/2017</endDate> </item> </request>'
