Integrating Perl with web services using webhook functionality

I’m trying to connect my Perl script to various web apps using webhooks. I’ve heard this method can save me from dealing with individual APIs for each app. My goal is to send JSON data via POST and then process the response.

Here’s the code I’ve written so far:

my %info = (
    user_id => '9876',
    username => 'JohnDoe',
    contact => '[email protected]',
    mobile => '9876543210',
);
my $info_ref = \%info;

my $client = HTTP::Tiny->new();
my $encoded_data = $client->www_form_urlencode($info_ref);
my $result = $client->post_form($endpoint, $encoded_data);

However, I’m running into an error: ‘Usage: $client->www_form_urlencode(DATAREF)’. Can someone help me figure out what I’m doing wrong? I’m not sure if I’m encoding the data correctly or if there’s an issue with how I’m sending the POST request.

I’ve encountered similar issues when working with webhooks in Perl. The problem lies in how you’re encoding and sending the data. For JSON payloads, you should use the JSON module instead of www_form_urlencode. Here’s a more effective approach:

use JSON;
use HTTP::Tiny;

my $json = encode_json(%info);
my $client = HTTP::Tiny->new();
my $response = $client->post($endpoint, {
content => $json,
headers => {‘Content-Type’ => ‘application/json’}
});

This method properly encodes your data as JSON and sets the correct Content-Type header. It’s crucial for most webhook implementations. Remember to handle the response appropriately, perhaps using decode_json if you’re expecting a JSON response. Let me know if you need any clarification on this approach.

u might wanna try using the JSON module instead of www_form_urlencode. it’s better for sending JSON data. here’s a quick example:

use JSON;
my $json = encode_json(\%info);
my $response = $client->post($endpoint, {
    content => $json,
    headers => {'Content-Type' => 'application/json'}
});

this should work better for webhooks. good luck!

I’ve worked with Perl and webhooks before, and I can see where you’re running into trouble. The issue is with how you’re handling the JSON data. Instead of using www_form_urlencode, you should be using the JSON module to properly encode your data.

Here’s what I’d suggest:

use JSON;
use HTTP::Tiny;

my $json = encode_json(\%info);
my $client = HTTP::Tiny->new();
my $response = $client->post($endpoint, {
    content => $json,
    headers => {'Content-Type' => 'application/json'}
});

This approach properly encodes your data as JSON and sets the correct Content-Type header, which is crucial for most webhook implementations. Don’t forget to handle the response too - you might want to use decode_json if you’re expecting a JSON response back.

Also, make sure you have the JSON module installed. You can do this via CPAN if you haven’t already.

Let me know if you run into any other issues!
