Endpoint URL
Copy the webhook endpoint from WordPress and use it as the destination in the system you want to test.
Simple Webhook Tester for WordPress
Test webhooks directly in WordPress.
Receive webhook requests, inspect payloads and headers and see what an external system actually sends — directly inside WordPress.
Freeware WordPress plugin by KuuraStack.
See the actual request
Give the source system an endpoint and inspect what arrives.
Simple Webhook Tester creates a webhook endpoint in WordPress. Send a request to it from another system and inspect the captured request in the WordPress admin.
Receive the request
Trigger the webhook in the source system and let WordPress capture the incoming request.
Inspect the data
Review the payload, headers and request details instead of guessing what the external system is sending.
No test server required
Find out what the source system really sends.
Point the webhook at WordPress, trigger the event and inspect the captured request before building the final integration.
Request details
Inspect more than the payload.
Useful webhook debugging often depends on the metadata around the request as much as the JSON inside it.
Request information
- Arrival time
- Event information
- Payload size
- Returned HTTP status
HTTP details
- HTTP headers
- Content-Type
- Sender IP
- User-Agent
Signature information
Configure a signing secret when the source supports signed webhooks and inspect whether signature verification succeeds.
Raw JSON
See the payload exactly as it arrived.
Inspect the raw JSON instead of relying only on a formatted summary of the request.
This makes it easier to understand field names, nesting, IDs, arrays and other details before mapping the data into another system.
Unknown payloads
You do not need to know the structure in advance.
Simple Webhook Tester can be used when documentation is incomplete or when you simply want to verify what the source application actually sends.
Trigger the webhook first. Inspect the structure afterwards.
Testing workflow
From endpoint to inspected request.
1. Copy the endpoint
Install and activate the plugin, open Simple Webhook Tester and copy the generated endpoint URL.
2. Configure the source
Add the endpoint to the external application and configure an optional signing secret when required.
3. Trigger and inspect
Trigger the source event and inspect the captured request inside WordPress.
Useful for
Debug webhook integrations before connecting the final destination.
Simple Webhook Tester is not tied to one plugin or external service. If a system can send a webhook, the endpoint can help you inspect it.
WordPress plugins and forms
Test webhook output from WordPress plugins, forms and ecommerce workflows.
Apps and APIs
Inspect webhook requests from custom applications, APIs, CRM systems and other external services.
Automation workflows
Verify the request before routing it into an automation platform, CRM, ERP or another production integration.
Before the integration
Understand the payload before you start mapping it.
Test the source request first, then build the Make, Zapier, n8n, CRM, ERP or custom integration around data you have actually seen.
Signature verification
Check signed webhook requests.
When the source system signs webhook requests, configure the signing secret and use Simple Webhook Tester to verify the signature as part of the test.
This helps confirm both the payload and the security mechanism before implementing the final receiver.
Debug Report
Create useful diagnostic information when troubleshooting.
Debug information can help when a webhook behaves differently than expected or when another developer needs to understand the captured request.
A Debug Report may contain personal, confidential or otherwise sensitive information from the webhook payload or request metadata. Always review it before sharing.
Works with Answer Builder
Inspect detailed WordPress form webhooks.
Answer Builder can send structured webhook data containing form and response information, questions and answers, person or company data, calculations, file metadata and other submission details.
Simple Webhook Tester provides a practical way to inspect that data while developing or debugging the receiving workflow.
