refers to the general technology of how Web-based systems talk to each other. </p> <p>In short, many systems (for example, a payment platform and a customer management system) communicate with each other by sending Web requests back and forth, for example, from <code>https://paymentsys.example</code> to <code>https://customersys.example/register-payment</code> and vice-versa.</p> <p><a

<p>Webhook.site is a tool for building software that not only use webhooks but other types of communication, either by allowing developers to inspect the data that's being sent via a webhook, but also helps users create workflows that respond to and interact with webhooks from various systems.</p> <p>When visiting <a href="https://webhook.site">Webhook.site</a>, users instantly get a free, unique, random URL and e-mail address. Everything that's sent to these addresses are shown instantly. With this, users can test and debug Webhooks and HTTP requests, as well as create workflows using the <a href="/custom-actions.html">Custom Actions</a> graphical builder or <a href="/webhookscript.html">WebhookScript</a>, a simple scripting language, to transform, validate and process HTTP requests in a variety of ways – without setting up and maintaining your own infrastructure.</p> <p>Webhook.site is a <a href="https://datacvr.virk.dk/enhed/virksomhed/41561718">registered corporation</a> in Denmark since August 2020.</p> <h3 id="company-information">Company information<a class="headerlink" href="#company-information" title="Permanent link">¶</a></h3> <p>Webhook.site company stats as of Feburary 2025:</p> <ul> <li>300.000+ monthly unique users</li> <li>2300+ subscribed customers</li> <li>460 million HTTP requests per day</li> </ul> <p>Webhook.site is operated by Webhook ApS (VAT ID: DK41561718).</p> <p>Address: Skibsbyggerstræde 20 5. th, 5000 Odense, Denmark.</p> <p>Company director: <a href="https://simonfredsted.com">Simon Fredsted</a>.</p> <p><a href="https://support.webhook.site">Contact information</a>.</p> <h2 id="what-are-some-common-uses-for-webhooksite">What are some common uses for Webhook.site?<a class="headerlink" href="#what-are-some-common-uses-for-webhooksite" title="Permanent link">¶</a></h2> <ul> <li>Receive Webhooks without needing an internet-facing Web server</li> <li>Creating advanced workflows/automations that run when a URL is requested or an email is received</li> <li>Use Webhook.site as an intermediary or gateway, proxying and forwarding requests and being able to see what was sent in the past</li> <li>Send Webhooks to a server that's behind a firewall or private subnet</li> <li>Transforming Webhooks into other formats, and re-sending them to different systems</li> <li>Connect different computer systems or APIs that aren't compatible</li> <li>Building contact forms that e.g. send emails</li> <li>Instantly build APIs without needing infrastructure</li> </ul> <p>The following video is a quick demo of Webhook.site Custom Actions is used to set up a workflow to post updates from a news page to an X/Twitter account automatically.</p> <p><center><iframe width="100%" height="440" src="https://www.youtube.com/embed/wg08ny5bh9w" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe></center></p> <h2 id="why-should-i-pay-for-a-webhooksite-subscription">Why should I pay for a Webhook.site subscription?<a class="headerlink" href="#why-should-i-pay-for-a-webhooksite-subscription" title="Permanent link">¶</a></h2> <ul> <li>URLs never expire (free URLs expire after 7 days)</li> <li>No limit on the amount requests, emails, DNSHooks a URL can receive (free URLs accept a max of 100)</li> <li>The data sent to your URLs is protected in your account</li> <li>Custom aliases for your URLs (https://webhook.site/my-alias)</li> <li>You can manage your URLs with our Control Panel</li> <li>Unlimited e-mail support</li> <li>Features like Custom Actions, CSV Export and Schedules</li> <li>Higher rate limits on API endpoints</li> </ul> <p><a href="https://webhook.site/register">Click here to create a Webhook.site subscription</a>.</p> <h2 id="is-my-data-private">Is my data private?<a class="headerlink" href="#is-my-data-private" title="Permanent link">¶</a></h2> <p>Yes. Per default, all URLs associated with a paid Webhook.site subscription are protected with login. Additionally, users can decide exactly how much (or little) data Webhook.site stores, either by amount of requests/emails, how long a URL stays active or other criteria, like the content of a request or email.</p> <p>For users of the free version of Webhook.site, as the free version operates without a login, data is accessible to anyone who knows the ID of the URL.</p> <h2 id="can-i-use-webhooksite-for-production-workloads">Can I use Webhook.site for production workloads?<a class="headerlink" href="#can-i-use-webhooksite-for-production-workloads" title="Permanent link">¶</a></h2> <p>Yes.

(If you want to store data permanently, you can use Custom Actions to transfer data to a storage provider like AWS S3 or Dropbox.)</p> <p>For free users of Webhook.site (URLs not associated with an upgraded account), the URL stops accepting new requests and emails after a limit of 100 requests or emails.
