But when execution from the workflow (including API key + password) I get this error message.
[0007] W3730 : Error resolving the URL : Error connecting with SSL.
[0007] HTTP Client Input: W1603 : Plugin failed - 10:51:14 (elapsed time: 00:00:00.018)
I would surmise that the server is expecting a TLS encryption level that’s not supported by the HTTP Client Input task.
You will probably have to use a script instead.
Something like:
var http = new ActiveXObject("Microsoft.xmlhttp");
http.open("GET","https://api.mailjet.com/v3/REST/message?CustomID=00056678_",false);
http.send();
var fso = new ActiveXObject("Scripting.FileSystemObject");
var responseFile = fso.createTextFile(Watch.GetJobFileName(), true);
responseFile.writeLine(http.responseText);
responseFile.close();
Notes:
This code is untested, I wrote it off the top of my head, so you’ll probably have to tweak it.
The code overwrites the current job file.
No authentication is provided. If Mailjet supports basic authentication, then you can simply change your URL to use a format like https://username:password@api.mailjet.com/...
