Let’s face it—the term “webhook” doesn’t exactly scream “user-friendly.” It sounds more like something you’d call IT about, hoping they can fix it before your laptop catches fire.

Webhook meme

But here’s the good news: webhooks are way less complicated than they sound! 

They’re actually a genius way to take the grunt work out of scheduling. If you’re juggling too many tools and drowning in admin tasks, webhooks can connect everything for you. 

In this article, we’ll break down all the key info you need to understand about webhooks and how to use them in scheduling automation. By the time you’re done reading, you’ll be a webhook pro—and (dare we say it) maybe even a fan.

What are webhooks?

Our goal for this section is to take you from “afraid to ask Andy” to “excited (about webhooks) Andy.” 

Ready?

To start, picture this: You’re running a busy café, and every time someone orders a meal, you have to run to the kitchen and tell the chef what to make. Exhausting, right?

Now instead, imagine that order instantly being sent to the kitchen without you lifting a finger. That’s essentially what a webhook does—but for your software!

Webhooks are a way for different apps to share information automatically when triggered. They basically let completely separate tools talk to each other. 

For example, when someone books an appointment using your scheduling tool, a webhook can instantly send that info to another app you use, like your calendar, email, or CRM. It’s like a helpful messenger delivering updates for you.

How do webhooks work?

Here’s a quick overview, using a booking app as an example:

  1. Something happens: Let’s say a client books a meeting with you.
  2. The webhook notifies another app: Your online scheduler sends a webhook to Trello.
  3. The other app takes action: Trello gets the message and automatically creates a task to prepare for the call, complete with key client details and a checklist for pre-meeting research—all without any copying, pasting, or manual updates on your part!

How webhooks enhance scheduling automation

Now that you know what webhooks are and how they work, you might be asking yourself—why should I care? Because webhooks can take your scheduling workflow from clunky to cutting-edge.

Let’s break it down:

1. Connecting scheduling tools to other systems

Webhooks make it easy to sync your scheduling software with other tools you use daily. For instance:

  • Connect your scheduling tool to a CRM like HubSpot to automatically log client meeting notes or new client details.
  • Send appointment updates directly to team channels in Slack to keep your team in the loop of new bookings.
  • Create new tasks in project management tools like Trello or Asana whenever a booking is made so your team knows what needs to be prepped.

2. Trigger-based automation

Webhooks can trigger helpful actions whenever something happens in your scheduling tool, saving you hours of manual work. Here are a few examples:

  • Generate an invoice automatically: When a booking is confirmed, trigger an invoice in QuickBooks, Xero, or FreshBooks.
  • Segment customers for future marketing: If a first-time client books, tag them in your email marketing platform for targeted follow-up emails.
  • Update employee schedules: If a new meeting is booked, you can update the internal schedule in your HR system via a webhook.

Real-world examples of webhooks in action

1. Real estate agencies: Keep your CRM and team in sync

Imagine you’re a real estate agent juggling multiple property viewings and client meetings. Webhooks make it easy to stay organized. For example:

  • A client books a property tour on your real estate scheduling app.
  • A webhook instantly sends the booking details (name, email, time, and location) to your CRM, automatically creating or updating the client’s record.
  • Another webhook notifies your team on Slack or via email about the new booking, ensuring everyone is on the same page.

2. Healthcare providers: Charge a no-show fee

For clinics, therapists, and other healthcare providers, missed appointments can be an expensive problem.

In fact, each missed visit costs roughly $185, and with some practices reporting patient no-show rates as high as 80%, the revenue loss can quickly add up. Not to mention, you’ll be able to help less patients.

Here’s how webhooks can help:

  • A patient books an appointment through your medical services scheduling software and agrees to the no-show and cancellation policy you included on your booking form.
  • If they don’t show up, a webhook automatically charges a no-show fee through Stripe.
  • This helps minimize no-shows and ensures your practice doesn’t lose revenue in case of missed appointments.

3. Service-based businesses: Automate invoicing and payments

If you run a service-based business—like consulting, personal training, or event planning—webhooks can streamline how you handle payments and invoices. For example:

  • A client books a session through your professional services scheduling software.
  • A webhook sends the booking details to your invoicing software (e.g., QuickBooks or Xero), automatically generating an invoice for the client.
  • If you use a payment processor like Stripe, another webhook triggers when the client pays, marking the invoice as "paid" in your system and sending the client a receipt.

Adding webhooks to your scheduling workflow: A step-by-step guide

Ready to finally add webhooks to your scheduling setup? The steps are pretty simple:

1. Find a webhook-friendly scheduling tool

The first step is the easiest—make sure the scheduling software you’re using supports webhooks. Here’s a quick hint: YouCanBookMe (YCBM) is one of those tools!

Thank God I found YouCanBookMe because it really had every feature that I needed. Other booking platforms only let you do things on their site, but YouCanBookMe was way ahead of the others because it offered webhooks."

- Juan Gartner, Co-founder of Test Drive

2. Choose the actions that will trigger your webhook

Triggers are the events in your online scheduler that “fire off” a webhook. Think of these as the moments when you want a certain action to happen. Some common triggers include:

  • New booking created: When a client schedules an appointment.
  • Reminder sent: When a reminder is sent to a client.
  • Booking canceled: When someone cancels their appointment.
  • Booking finished: After someone finishes an appointment.

3. Decide where you want the webhook to send the data

Webhooks need a “destination”—a place where the data will be sent so it’s not just floating around going nowhere fast. This destination is called the webhook endpoint or URL.

The destination could be:

  • Your CRM (like Salesforce or HubSpot) to update client records.
  • A notification tool (like Slack) to alert your team.
  • Your email platform to trigger automated emails.

Bonus How do you find or create your webhook endpoint or URL?

  • If you’re sending info to another tool, like Slack or a CRM, check the app’s settings or documentation for webhook URLs. Most tools will have instructions ready for you!
  • If you’re using an automation tool like Zapier for webhooks, simply create a new Zap, select “Webhook” as the trigger, and Zapier will give you a unique URL to use.

4. Customize the payload

“Customize the payload” sounds daunting (and kind of odd, to be honest), but it just means choosing what information the webhook will send. 

For example, when someone books an appointment, the payload might include:

  • The client’s name and email address.
  • The date, time, and location of the booking.
  • Any custom notes or questions they filled out on your booking form.

Most scheduling tools let you choose what information gets sent when the webhook is triggered. This information is sent via JSON, which stands for JavaScript Object Notation.

Don’t know what JSON is? No worries, here’s a bite-sized 🍕overview:

JSON is simply a way to send data so that computers and software can easily understand it. 

It includes keys (a.k.a. labels) and values (a.k.a. the actual data).

Examples of JSON keys:

  • “Name”
  • “Email”
  • “Date”

Examples of JSON values:

  • “John Doe”
  • “johndoe@example.com”
  • “January 31, 2025”

In YouCanBookMe, you’ll often find pre-filled JSON already set up for you. This means you don’t have to start from scratch—just modify it to fit your needs or use it as is!

Here’s an example of JSON straight from YCBM:

{ "startsAt": "{START-LOCAL-DATE}", "endsAt": "{END-LOCAL-TIME}", "timeZone": "{TIMEZONE}", "firstName": "{FNAME}", "email": "{EMAIL}" }

This simply means the webhook will send info about the meeting start and end time, timezone, booker’s first name, and their email address. Easy.

💡 Note: The information in your webhook is completely customizable based on the details you collect in your booking form.

For example 👉 if you’ve set up custom fields like "Phone Number" or "Appointment Type," your webhook can include those too. YouCanBookMe uses shorthand codes to pull this info, so your webhook will always send the exact details you need—nothing more, nothing less.

5. Test your webhooks

So you made it through creating your first webhook, congratulations! Now it’s time to test it to make sure everything’s working as it should.

How to test your webhooks:

  • Use a free webhook testing tool like Webhook.site or RequestBin. These tools generate a temporary URL that you can use as your webhook destination.
  • Make a test booking in your scheduling tool, then complete the action you’ve chosen to trigger the webhook (like rescheduling or canceling the booking). After that, check the testing tool to see if it received the data correctly.
  • If everything looks good, replace the test URL with your actual webhook endpoint.
