invokeurl marinetraffic

Hello friends. I can't find the error in this call, and it returns "null". Does anyone know what could be happening?

I have tried the call writing it by hand and it works perfect. Obviously XXX to not expose the API key.

// API key for PS07 Single Vessel Positions API

api_key = "XXX";

// Query parameters for API call

shipid = 758977;

timespan = 2880;

msgtype = "simple";

protocol = "json";

// Make API call and get response

response = invokeurl("https://services.marinetraffic.com/api/exportvessel/" + api_key + "/v:1/shipid:" + shipid + "/timespan:" + timespan + "/protocol:" + protocol + "/msgtype:" + msgtype);

info response ;
