When you receive a blockchain deposit, you can use the txNotify API call to check if there is a travel rule message that matches the transaction details.
​
​What is txNotify?
​txNotify is an API endpoint used by the beneficiary VASP to check if an incoming blockchain deposit has a matching travel rule message.
​

How does txNotify work?
When txNotify is called, an initial search is performed to identify Travel Rule data associated with the exact same transaction hash and destination address. If a match is found, the result will point to the existing Travel Rule transfer. However, if there is no match, a new travel rule transfer will be created with the status of incomplete. If the originator VASP is identified based on the originator wallet address, Notabene will automatically send a request to them to provide the missing data. In cases where the originator VASP is not identifiable in the network, additional data may be collected from the beneficiary end user.
