User-defined HTTP callbacks When something happens, ping this URL with this data Examples: When something sells, ping this URL When someone reverses a charge, lock their account Trigger a build of the website when the content changes Then someone buys a shirt, generate a shipping label and save it to the DB 07:57 - Sending End Can be a great way to hook two services together 09:13 - Receiving End Often you will be the one that accepts the webhook ping In this case, you set up an endpoint 11:00 - Payloads Almost all will send a JSON body that you parse out The method send is variable 11:51 - Auth On the receiving end of a webhook, you often get a token which you can then ping the service with. It will tell you if that request was legit or not. On the sending end, you can often set up headers with auth - same with the method Can be a replacement for a serverless function 13:18 - Testing webhooks Can be a pain in the ass ngrok - expose locally localtunnel Insomnia Postman Stripe has a great VS code extension Snipcart has an awesome dashboard Will also tell you when one failed webhook.site https://expose.dev/ IFTTT Zapier Tweet us your tasty treats!
