​
Webhook Overview

Bolta asynchronously sends tax invoice and cash receipt issuance and cancellation results to your registered webhook URL. Delivery timing differs by product - see the product page for details. Events are delivered as JSON via HTTP POST. For security reasons, only HTTPS communication is supported.
For webhook URL setup, see the Webhook Connection Guide. The test and live environments must be registered separately.

​
Firewall Settings

If the server that receives webhooks runs a firewall, add the IP address below to your inbound allowlist. It applies to both the test and live environments.

Event Types by Product

Each product page carries the payload examples, field descriptions, and delivery timing.

​
When a Webhook Does Not Arrive

Check any event you have not received with the status API. Use Retrieve Tax Invoice for tax invoices and Retrieve Cash Receipt Status for cash receipts.

​
Checking Webhook Logs

You can review the success/failure history of sent webhooks in the Developer Center > Event Logs.
