Im trying to register an endpoint but i get a notification saying that my format\_type is Invalid.

```auto

INVALID: unsupported format_type

```

I am setting it as

```auto

json/post

```

Any help here would be appreciated.

Thanks

Can you show your code for invoking it. I suspect the arguments aren’t getting passed correctly.

Im using the golang library. But the fields are the same. If there a way to check on the server, how it received the request? My code is below.

```auto

	response, err := flightaware.DefaultLocalAPIClient.RegisterAlertEndpoint(
		basicAuth.NewContext(context.Background()),
		&flightaware.RegisterAlertEndpointRequest{
			Address: "http://requestb.in/swvaqhsw",
			FormatType: "json/post",
		},
	)

```

It would be easier if you enable verbose debugging to see how the request is being serialized. The capitalization of the arguments in your source code does not match our documentation/wsdl, so I hope your library is responsible for adjusting the output request to match our expectations.

Capitialization is just a part of the the conversion from wsdl to golang. So it should not be a problem. I am infact having this problem with the register endpoint call, have been making the FlightInfo call all day and its been giving me the appropriate response.

Can you confirm whether this line is using URL encoding or JSON encoding? It really needs to be GET-style form variables, or POST using application/x-www-form-urlencoded.
