Getting error "{"fault":{"faultstring":"The Service is temporarily unavailable","detail":{"errorcode":"messaging.adaptors.http.flow.ServiceUnavailable"}}}" When tried to run the API using APIKey.
What's the response when you don't provide API key? Can you trace the proxy and see requests hitting it?
can you open trace and check? The error seems because of some different reason.
The 503 error you are seeing is indicative of something other than a bad APIKey.
Faults for bad API key validation errors can be found here.
Thanks for the response. Issue resolved. As my API wasn't deployed over the web network.
