Webhook Payload Generator
Generate webhook payloads with HMAC signatures for Stripe, GitHub, Slack, Shopify, Twilio, SendGrid, Discord and more
What Webhook Payload Generator does
The Webhook Payload Generator on Inventive HQ is a developer utility that creates realistic JSON or XML payloads for simulating events across major platforms like Stripe, GitHub, Slack, Shopify, Twilio, SendGrid, and Discord. Users select a target service, and the tool populates the required fields into a structured format, allowing them to construct sample data bodies that mimic live events without writing code. The generator also supports adding cryptographic HMAC signatures, which helps validate that integrations will correctly process incoming webhook data. This makes it useful for testing, debugging, and documenting how different services handle incoming events.
How to use the Inventive HQ Webhook Payload Generator
- 1
Choose the target platform from the service list to populate required fields

Paste the payload into your webhook receiver to simulate the event
Best for
Developers and testers who need to quickly simulate webhook events or validate integrations without writing custom code or sample data.
Limitations
- Results are estimates based on platform defaults
- No unit or format conversion between JSON and XML
- HMAC generation requires user-provided secrets
Webhook Payload Generator FAQ
- Can I generate payloads for platforms not listed in the dropdown?
- The tool supports major platforms like Stripe, GitHub, Slack, Shopify, Twilio, SendGrid, and Discord. Payloads for unsupported services would need to be constructed manually using the blank JSON template.
- Is the generated HMAC signature guaranteed to match my webhook secret?
- The tool generates an HMAC using the secret you provide. It will match your integration as long as the same secret and payload content are used on your server.
- Do I need to install anything to use the webhook payload generator?
- No installation is required. The tool runs entirely in your browser, and you can generate and copy payloads instantly from the website.
- Can I export the payload as a file or save it for later use?
- The interface allows you to copy the generated JSON or XML output to your clipboard. There is no built-in save or export feature within the tool.
