If the word webhook makes your brain say, “That’s IT’s problem,” you’re not alone.

Most marketers avoid them because they sound too technical, full of code, APIs, and things we’d rather not break.

However, once you understand what they do, webhooks become one of the simplest and most powerful tools for lifecycle automation.

Today’s issue breaks it down simply:

  • What a webhook really is (in plain English)

  • How to safely test one in Braze

  • And a step-by-step guide to create your own blank webhook for QA

💡 Note: The screenshots and steps in this guide use Braze for clarity, but the same concept applies to any marketing automation platform, like Salesforce Marketing Cloud, HubSpot, Iterable, or Klaviyo.
Once you understand how a blank webhook works, you can replicate this setup in nearly any tool.

How to Create a Blank Webhook in Braze (for Testing and QA)

Deep Dive

What’s a Webhook?

A webhook is just a bridge that lets Braze talk to another system automatically.

When something happens (like a user signing up or completing a purchase), Braze can instantly “ping” another app with that info - like saying:

“When X happens here, tell Y over there.”

“Hey, Stripe, this customer just bought something - update their payment record.”

“Hey, Slack, send a message to the #sales channel, a new signup came in.”

No manual export. No waiting. Instant data flow.

Step-by-Step: How to Create a Blank Webhook in Braze

1. Navigate to the Webhook Composer

Go to Messaging → Campaigns → Create Webhook (or just add a Webhook step inside a Canvas).

2. Compose a Webhook from Scratch

Click “Compose Webhook from Scratch.”

In the Webhook URL field, enter: 

<https://braze-images.com/spacer.gif>

This Braze-owned URL safely returns a 200 OK response - perfect for testing.

3. Set HTTP Method

Choose GET.

It requests data instead of sending it, keeping your test clean and non-intrusive.

4. Add Headers (Optional)

If your real webhooks use authentication or custom headers, you can add them here to validate the setup.

Example: 

Content-Type: application/json
X-Braze-Test: true

5. Review Delivery Logs

Send a test or trigger the webhook via Canvas.

  • Status: “Sent” or “200 Success” or “200 OK”

  • Response: Empty but successful

If you see all these, your logic is solid.

  • A guaranteed safe URL with 100% uptime

  • A quick “success” signal to confirm timing

  • No risk of touching live data or APIs

Pro tip:

You can save your webhook as a template too. Templates > Webhook Templates. Once its saved, you can easily pull them in your canvases when needed.
