Webwrite isn't meeting my needs for POSTing data to a RESTful web service, so I decided to go with the lower level matlab.net.http.RequestMessage functionality, which sometimes works, but setting the Header with my authorization token sometimes fails depending on the token I get.
URL = 'https://api.tdameritrade.com/v1/accounts/1234567890/orders'; r = matlab.net.http.RequestMessage; r.Method = 'Post'; r.Header(1).Name = "Authorization"; r.Header(1).Value = "Bearer " + token; % Token is long and changes periodically. **Usually** Matlab throws error
token = "zgzMa4kOwPmVxbQ3tp0unIp4JIXv1Hzh7fzRs3JmQbTnPVFeXX7oF2pJH+3gL4KYEfXFIuiL7IKHOJRUdxe0HXnU0yN+Gn9cZUyU/eovZVyG4kVTqu47hyDnNkq0C1gShWhBtWcvI8uKjzHjGMJP8Ot2Gjhbw3/l6YfQe3q3PBQ+6wLsSV7gHBm406PukLdql7schTpvrqLi8h308G7OIVrTJB2oXgqfIVGGDYbQNuw6iGamxJUqOZ8Fv8PeRapG92iT8B1p1sW5LFq5Vpu6N2pFgkhoSilmW0aZ+aq03R9V8FYFsZ30/jrNqSxllf3WFELkVYlJlGNOvudzIzJwANcfcl4UzvDYpduN33lOarpIK3a17tRlsjIimtgiLhyxEYlUnVLiuwI5l1+9tkJ0HjC3asEL6kWj+ysW5gx36YWyb8tbhOz5I5wFkqGkcjZNJjUQ12Ou4+DVG/tCwhCHwJOR+x8imWbZqTcDwNRMKyQkn1CXSY463Ycxf3XE6boRBkK2OtAQ/m4Q276i26HhRGjuMFfDW1fzCrrXy23zERVAkAo9t100MQuG4LYrgoVi/JHHvlwCIoz+tGIgiaHeuLUSTR/PGs5RLwaXaMkRXixdeWNw5qOODbq9fsFHe0zBCweEkN8CK5Uxa3+FXv3OtlJUDZ8Pytum96pRkgDPvib1n2sDmtV0DgHc1q2zJqfitAcfS3lmIYPx7RcGBHJV/jn1Ojp6mcN9tu0C8S7u/Mk4gqV+dwkdLIICRGe3u2ASbsX6j16Nrbv+XHy9sxQRVh0eWpvLppM0ICBlSxrZ6qr/d6pYqn505fB6gICX0D+326pFZF/fgcyLnfGjCaHv9v5qMv0LTNooGYZ5BguM4IZGOCts4h+/zm3wGCchBczi3BWh/AXw+fNro1TOAkGDdzshZs6GyBoo52vziYR319E/pep9qDs0talrh1OJGnOOquBhnqY9ej2kzQdDtf3sBxQjSXn3JEIlAcszSCQbPDwwrr5sPDMWuhHsgbuU1+CIGOPEKiL0zi57fne5zTjAvMBov8/FWmCULZ+dEGRiBfdqK4OJMyZn8Kpcq+oN2JYSOBcE+c/6Y3XrOjW/8D1U+Hvb2sYhWk/f1hYh2AHDO2dwlbCoRtPipQ==212FD3x19z9sWBHDJACbC00B75E"
Note that I can set the header with webwrite and successfully use the RESTful service that way, but unfortunately the response when using webwrite is empty and I need the info that gets returned from the non-webwrite approach described above.

URL = 'https://api.tdameritrade.com/v1/accounts/1234567890/orders';
r = matlab.net.http.RequestMessage;
r.Method = 'Post';
genericHeader = matlab.net.http.field.GenericField('Authorization',"Bearer " + token); % This bypasses Matlab value validation
r.Header = genericHeader; % Assign to RequestMessage. Fortunately, the RequestMessage class accepts generic header objects
r.Body(1).Data = order; % trade/order to POST
response = r.send(URL); % Works like a charm and output contains the info I need.
I hope this helps someone else out there.
