   Msgdrop – Test emails, webhooks and 2FA using a simple API▲5

   Hey HN crowd, I'll spare the marketing speak and talk straight and honest here which I think most of you will appreciate. I was on a team not too long ago where we needed to test emails from an automated test run. Think of the stuff like magic login links, verification links, etc. Normally when we had such cases then these user journeys were tested manually by our QA engineers and this always bugged me a lot. None of the tools which we found on the internet really convinced us. They were either completely open and wholly insecure or only accessible through a UI and very cumbersome to use.…

    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.
