    I made an online Webhook Tester▲43

    Hi HN! Last year, I built LocalCan app in which you can develop apps using .local domains and Public URLs. Although it allows for testing webhooks too, I wanted to give back and create a free online tool specifically for that purpose! And so, I've made Webhook.cool Simply use your unique webhook URL to send any webhook to it from services like Shopify, Slack, Mailchimp, Trello, GitHub, PayPal, Discord, and Jira. Give it a try and let me know how if you have any feedback.
