I need to set the Bearer Token field to 'Authorization : "Bearer <token>"' to pull data from an API however I have not been able to set this value. I have tried using the weboptions() function, but the HeadersFields field will not accept strings -- it appears to only accept numeric-type.
r= weboptions;
r.HeaderFields = 'Authorization : "Bearer <token>"';
This gives an error (r2019a). What's wrong with this statment?

You should add brackets:
'HeaderFields',{'Authorization', ['Bearer ' token]});

You can make a request using Bearer token base authentication using the following code.
function [resp, a, req] = webread2(URL,Message,BearerToken)
MyBody = matlab.net.http.MessageBody(Message);
MyHTTPOptions = matlab.net.http.HTTPOptions();
Request = matlab.net.http.RequestMessage;
Request.Method = 'POST';
Request.Header = matlab.net.http.HeaderField('Content-Type','application/json','Authorization', ['Bearer ' BearerToken]);
Request.Body = MyBody;
uri = matlab.net.URI(URL);
[resp, a, req] = Request.send(uri,MyHTTPOptions);
end
