Webhooks & API Access

Webhooks let external systems notify EventHex when events happen (like payment completions). This page covers payment webhook setup and API access for developers.

Payment Webhooks

Payment gateways use webhooks to confirm transaction outcomes. EventHex automatically configures webhooks for supported payment providers.

Stripe Webhooks

When you connect Stripe, EventHex automatically creates webhook endpoints in your Stripe account. These webhooks notify EventHex when:

A payment succeeds
A payment fails
A refund is processed
A subscription changes

Check Webhook Status:

Go to Settings → Payment and look for the webhook status indicator. A green checkmark means webhooks are active and receiving events.

Razorpay Webhooks

For Razorpay, configure the webhook URL in your Razorpay dashboard:

https://api.eventhex.ai/webhooks/razorpay/{your-event-id}

Set up the webhook to send notifications for:

payment.captured
payment.failed
refund.processed

Webhook Logs

EventHex logs all incoming webhook events for debugging:

Timestamp — when the webhook was received
Source — which payment provider sent it
Status — success or failure
Payload — the raw webhook data

Use webhook logs to troubleshoot payment issues. If a customer says they paid but their registration isn’t confirmed, check the webhook logs for their transaction.

API Access

EventHex provides API endpoints for developers who need to integrate with external systems.

Common API Use Cases

Pull registration data into your own analytics platform
Sync attendee lists with external CRM systems
Build custom registration flows
Automate badge printing with external hardware

Authentication

API requests require authentication via API keys or OAuth tokens. Contact EventHex support to request API access for your organization.

Troubleshooting

Issue	Solution
Payments not reflecting in EventHex	Check webhook status in Payment settings. Re-create webhook if status shows error
Webhook delivery failing	Verify the webhook URL is correct in your payment provider’s dashboard
Duplicate payment entries	Check webhook logs for duplicate delivery — configure idempotency on your payment provider
Razorpay webhook not working	Ensure the webhook URL includes the correct event ID and the webhook secret matches
