Chaingateway Webhooks is a service that allows you to receive real-time notifications for blockchain events, such as incoming and outgoing transactions, by sending POST requests to your specified endpoint whenever relevant events occur.

An Instant Payment Notification (IPN) is a message sent by Chaingateway to your specified endpoint whenever a relevant blockchain event occurs, such as an incoming or outgoing transaction. This allows you to receive real-time updates and take immediate action based on the event data.

To set up a webhook, you need to create a secure endpoint on your server that can receive POST requests. Then, you can use the Chaingateway dashboard or API to create a webhook and specify the URL of your endpoint along with any desired filters for the events you want to receive notifications for.

You must supply url (public endpoint) and at least one of from or to. Additional optional filter arguments are contractaddress, token_id, and type (ETH/ERC20/ERC721 for Ethereum, and similarly for other chains).

Each POST includes id, webhook_id, from, to, blocknumber, datetime, tokenid, type, contractaddress, txid, amount, and other bookkeeping fields so you have everything to reconcile payments.

Every delivery is signed with X-Signature (HMAC SHA-256 over txid + your secret, Base64). Failed calls retry for 72 hours and appear in the delivery log so you can replay or alert; test events help validate your handler during development.

No. The webhook service calls your public endpoint over the open internet—just ensure your firewall allows incoming traffic without IP whitelisting.

Use the Chaingateway dashboard to send test events to your endpoint, allowing you to verify that your handler processes the payload correctly before going live.

Use the X-Signature header to verify that incoming requests are genuinely from Chaingateway. This signature is generated using HMAC SHA-256 with your secret key, ensuring that only authorized events are processed by your endpoint.
