Complete Webhook Details

Complete the required details like webhook URL, Contract Address(es), and 'Events'.

For the Events field, we are able to parse any arbitrary contract event, however you must input the event exactly as written in your smart contract. For example, for detecting transfer events you would input: Transfer(address indexed from, address indexed to, uint256 amount) with the indexed keyword. You can find an example of general event types here for common use cases along with Sequence specific ones.

Once your desired fields are input, select Add Webhook.
