A webhook is a way for an app to provide real-time information to other applications. A webhook delivers data to other applications as it happens, meaning you receive data immediately. This is in contrast to APIs, which are typically queried for data on a regular basis.
To use a webhook, you must provide a URL to which the webhook can deliver its data. This URL is called the “callback URL” and this is where the webhook sends its data when an event occurs.
Let’s say you have an app that tracks mentions of your brand on social media. You can use a webhook to receive real-time notifications every time someone mentions your brand on Twitter. To do this, you would provide the Twitter API with the callback URL for your webhook, and the API would then send a notification to the webhook every time a tweet containing your brand’s name is posted.
Webhooks are typically used to enable real-time communication between apps, but they can also be used to automate workflows and perform other tasks. For example, you could use a webhook to trigger an automatic response to a customer’s email when they sign up for your mailing list.
Webhooks are a powerful tool for building integrations and automating workflows and are often used in conjunction with APIs to enable real-time communication between different applications.
