What is a Webhook?
The Complete Guide
for Business Owners
No jargon. No code required. Learn exactly what webhooks are, why every modern business needs them, and how to use tools like Zapier and Make to automate your entire operation — in plain English.
What is a Webhook? (Plain English)
A webhook is an automatic notification that one app sends to another the instant something happens. It's how modern apps talk to each other in real time — without any manual intervention.
The classic analogy: imagine you're waiting for a parcel. You could stand at the window and check every 5 minutes (that's an API poll). Or you could get a text message the moment the driver is outside (that's a webhook).
Webhooks are the backbone of modern business automation. Every time Stripe confirms a payment, Shopify processes an order, or a form is submitted on your website — a webhook can instantly trigger a chain of actions across your entire tech stack.
How a Webhook Works
Webhook vs API: What's the Difference?
Your app asks for data whenever it needs it. Like calling a restaurant to check if your table is ready.
- ✅ Good for on-demand data retrieval
- ✅ You control when requests happen
- ❌ Inefficient for real-time events
- ❌ Wastes resources with constant polling
The other app sends you data the moment something happens. Like the restaurant texting you when your table is ready.
- ✅ Real-time, instant notifications
- ✅ Efficient — only fires when needed
- ✅ No wasted API calls
- ❌ Requires an endpoint to receive data
6 Real-World Webhook Use Cases
Here's how UK businesses are using webhooks right now to save hours every week and eliminate manual data entry.
E-commerce Order Notifications
When a customer places an order on Shopify, a webhook instantly fires to update your inventory system, send a confirmation email, and notify your warehouse — all in under a second.
Shopify → Webhook → Inventory DB + Email + SlackPayment Confirmations
Stripe sends a webhook the moment a payment succeeds or fails. Your website can immediately unlock premium content, send a receipt, or flag a failed payment for follow-up.
Stripe → Webhook → Unlock Access + Send ReceiptCRM Lead Capture
When someone fills in your contact form, a webhook pushes the lead directly into HubSpot, assigns it to a sales rep, and triggers a follow-up email sequence — no manual data entry.
Contact Form → Webhook → HubSpot + Email SequenceBooking System Sync
A new appointment in Calendly triggers a webhook that adds the event to Google Calendar, sends a reminder SMS, and updates your client database simultaneously.
Calendly → Webhook → Google Calendar + SMS + DBSocial Media Automation
When you publish a new blog post, a webhook fires to automatically share it on LinkedIn, Twitter/X, and Facebook — and logs the post in your content tracker.
Blog CMS → Webhook → LinkedIn + Twitter + TrackerAI Workflow Triggers
A new customer review on Google triggers a webhook that sends the text to an AI model for sentiment analysis, then routes positive reviews to your testimonials page and flags negative ones for your team.
Google Reviews → Webhook → AI Analysis → ActionBest Webhook Tools: Zapier vs Make vs n8n

Zapier
The market leader with 7,000+ app integrations. If the app you use has a webhook, Zapier almost certainly supports it. The interface is the most intuitive of the three — most automations take under 10 minutes to set up.
Make.com
Formerly Integromat, Make has the best visual workflow builder in the market. You can literally see your data flowing between apps. At $9/mo for 10,000 operations, it's 5–10× cheaper than Zapier for the same workload.
n8n
The open-source option. Self-host on your own server for completely free, unlimited workflows. Ideal for technical teams who want full control. The cloud version starts at $20/mo. Has the best AI/LLM integration of the three.
How to Set Up Your First Webhook in 30 Minutes
A step-by-step guide using Make.com (our recommended tool for beginners). No coding required.
Sign up for Make.com
Create a free account at Make.com. The free tier gives you 1,000 operations per month — enough to test and run basic automations.
Sign up for Make free →Create a new Scenario
Click 'Create a new scenario'. This is Make's term for a workflow. You'll see a visual canvas where you'll build your automation.
Add a Webhooks trigger
Click the '+' button, search for 'Webhooks', and select 'Custom webhook'. Click 'Add' and copy the unique URL Make generates for you.

Go to the app that will send the webhook (e.g., Stripe, Shopify, your contact form). Find its webhook settings and paste Make's URL. Send a test event.
Add your action modules
Back in Make, click '+' after the webhook trigger to add actions — update a Google Sheet, send an email, add a row to your CRM, post to Slack. Chain as many as you need.
Test and activate
Run a test to verify data flows correctly. Check each module's output. When everything looks right, toggle the scenario to 'Active'. Your automation is live.
Webhook FAQs
What is a webhook in simple terms?
A webhook is an automatic message that one app sends to another when something happens. Think of it like a doorbell — instead of constantly checking if someone is at the door (polling), the doorbell rings (webhook) the moment someone arrives. When an event occurs in App A, it instantly sends data to App B without any manual action.
What is the difference between a webhook and an API?
An API is like a phone call — your app dials out to request information whenever it needs it. A webhook is like a text message — the other app proactively sends you data the moment something happens. APIs are 'pull' (you request data), webhooks are 'push' (data is sent to you automatically). Webhooks are more efficient for real-time events; APIs are better for on-demand data retrieval.
Do I need to be a developer to use webhooks?
Not anymore. Tools like Zapier, Make (formerly Integromat), and n8n provide no-code/low-code interfaces that let non-technical business owners set up webhooks without writing a single line of code. You simply connect apps, define the trigger event, and set the action — the tool handles all the technical plumbing.
What is the best webhook tool for small businesses in the UK?
For most UK small businesses, Zapier is the easiest starting point — it has 7,000+ integrations and a simple interface. Make.com (formerly Integromat) offers better value at scale with its visual workflow builder. If you have technical resources or want to self-host for cost savings, n8n is the most flexible option.
How much does it cost to set up webhooks for my business?
The webhook infrastructure itself is free — it's built into most modern apps (Stripe, Shopify, HubSpot, etc.). The cost comes from the automation platform you use to receive and process webhooks. Zapier starts at $19.99/mo, Make.com at $9/mo, and n8n is free if you self-host. For most small businesses, Make.com's free tier (1,000 operations/month) is sufficient to start.
Are webhooks secure?
Yes, when implemented correctly. Most webhook providers (Stripe, Shopify, GitHub) sign their webhook payloads with a secret key, allowing you to verify the request is genuine. You should always validate webhook signatures, use HTTPS endpoints, and implement rate limiting. Platforms like Zapier and Make handle much of this security automatically.
What happens if a webhook fails?
Most webhook providers implement retry logic — if your endpoint is unavailable, they'll retry delivery multiple times over several hours. Zapier, Make, and n8n also have error handling and logging built in, so you can see failed webhook deliveries and replay them manually. It's important to return a 200 HTTP status quickly to acknowledge receipt.
Can webhooks help my business save time?
Significantly. A typical small business that manually copies data between apps (CRM, email, accounting, inventory) spends 5–10 hours per week on repetitive data entry. Webhooks automate this entirely. Businesses using automation tools like Zapier or Make report saving 10+ hours per week and eliminating data entry errors.
What is the difference between Make.com and Zapier for webhooks?
Both support webhooks natively. Zapier is simpler and better for straightforward one-to-one automations. Make.com has a visual canvas that makes complex multi-step workflows easier to design and debug — it's particularly powerful for webhook-triggered workflows that branch into multiple paths based on conditions. Make.com is also significantly cheaper at scale.
How do I get started with webhooks for my business?
Start by identifying a repetitive manual task that involves moving data between two apps. Sign up for Make.com (free tier) or Zapier, create a new scenario/zap, choose 'Webhooks' as your trigger, and copy the generated URL into your source app's webhook settings. Test with a real event, then activate. Most simple webhook automations take under 30 minutes to set up.
