I try to create a PUT API call but I am not able to authorize my call.
username = 'APIDionSimi';
password = '****';
s.id = "e37b35dd-4aca-4ecb-8972-55c3a27a8b11";
data = jsonencode(s,PrettyPrint=true)
% data = jsondecode(s,Prettyprint=true);
body = matlab.net.http.MessageBody(data);
% authorizationField = matlab.net.http.field.AuthorizationField("APIDionSimi","NOgp!3808")
contentTypeField = matlab.net.http.field.ContentTypeField('application/json');
% autho = matlab.net.http.Credentials("Username","APIDionSimi","Password","NOgp!3808")
header = [contentTypeField]
method = matlab.net.http.RequestMethod.PUT;
uri = "https://apps.reeleezee.nl/api/v1/4a2dfa57-ff9a-400b-9c3a-b6a3beafd597/salesinvoices/fa19e531-ca5f-4682-b62a-f95d80175440"
request = matlab.net.http.RequestMessage(method,header,body);
resp = send(request,uri)
I tried several options without succes. Anyone who can help?

@Dion Theunissen - are you observing errors? Can you show the expected API format that you need to follow?

Hi Dion,
I understand that you’re trying to make a "PUT request" but are facing an issue in setting the Authorization headers.
You can do this using “HTTPOptions” class and “Credentials” class in in MATLAB. Here is a code snippet to help you with the same –
import matlab.net.http.*;
% Set the username and password for authorization
username = 'loremipsum';
password = '****';
% Specify the URI (URL) for the API call
uri = "<your_url_here>";
% Specify the HTTP method as PUT
method = RequestMethod.PUT;
% Create the content type field for the header
contentTypeField = field.ContentTypeField('application/json');
header = [contentTypeField];
% Create the credentials for authorization
credentials = Credentials('Username', username, 'Password', password);
% Set the HTTP options and assign the credentials
options = HTTPOptions;
options.Credentials = credentials;
% Create the data to be sent in the request body
s.id = "e37b35dd-4aca-4ecb-8972-55c3a27a8b11";
data = jsonencode(s, 'PrettyPrint', true);
body = MessageBody(data);
% Create the request message with the specified method, header, and body
req = RequestMessage(method, header, body);
% Send the request to the specified URI with the options
resp = send(req, uri, options)
Here are the links to the documentation of some the above-mentioned classes:
  1. "Credentials" class: https://www.mathworks.com/help/matlab/ref/matlab.net.http.credentials-class.html
  2. "HTTPOptions" class: https://www.mathworks.com/help/matlab/ref/matlab.net.http.httpoptions-class.html
I hope this helps!
Thanks & regards,
