URL and Json Issue

HI All.
I am making a webservice call out and I am getting the following reponse which I am not able to fix.

The body has the following reponse{"error": "Invalid Parameters supplied."}

If I  direclty type URL with Parameters in the Browser then it gets me data

{"data":[{"rh":65,"pod":"d","lon":-82.69343,"pres":1008.5,"timezone":"America\/New_York","ob_time":"2021-04-17 21:16","country_code":"US","clouds":75,"ts":1618694160,"solar_rad":425.4,"state_code":"FL","city_name":"Hudson","wind_spd":0.89,"wind_cdir_full":"west-southwest","wind_cdir":"WSW","slp":1009.2,"vis":5,"h_angle":60,"sunset":"23:57","dni":831.43,"dewpt":21.7,"snow":0,"uv":3.24984,"precip":0,"wind_dir":254,"sunrise":"11:01","ghi":608.39,"dhi":103.24,"aqi":52,"lat":28.36445,"weather":{"icon":"c02d","code":802,"description":"Scattered clouds"},"datetime":"2021-04-17:21","temp":28.9,"station":"C9863","elev_angle":37.99,"app_temp":31.7}],"count":1}

However,After constructing the same URL in the code I get the following error 

The body has the following reponse{"error": "Invalid Parameters supplied."}

So basically it looks like an issue with my URL.How do I fix it?

Here the rest link from the service supplier

Base URL.


Followwing is the Api Key


and I am passing Hudson as the city.


Here is my URL which I constructed in the code:-

String k='b3dbd1fd17094d04adab62cb4e9b8d23'; 

            String MapUrl=''+city+'& Key'=+k;
However,it gives me an error when I run code.

Can somebody help me in fixing this URL.

Hi Nitin,

I have tried running a test with the endpoint shared above in a dev org and following code should work fine for you:
Http http = new Http();

HttpRequest request = new HttpRequest();




HttpResponse response = http.send(request);

Ensure you have added following URL in remote site settings in Salesforce setup:

You can also make use of Named Credentials in Salesforce.
