Create script

Below you can see an example of script written in Perl language, but you can use your favourite language.

#!/usr/bin/perl -w

use strict;
use warnings;
use JSON qw( decode_json );


my $url = "https://jsonplaceholder.typicode.com/todos/1";


my $curl=`curl -s '$url'`;
# { "userId": 1, "id": 1, "title": "delectus aut autem", "completed": false }

my $decoded = decode_json($curl);


my $title = $decoded->{'title'};
print "SET VARIABLE RESULT_TITLE \"$title\"\n";

my $userId = $decoded->{'userId'};
print "SET VARIABLE RESULT_USERID \"$userId\"\n";

The script can be used as reference for your needs and remember to set properly the result of the cURL command:

print "SET VARIABLE <CHANNEL_VARIABLE> \"<VARIABLE>\"\n";
