Overview

Use this method to initiate the Travel Rule SDK, allowing the user to submit all required fields for a Travel Rule transaction.

Upon a successful request, the system will generate a token and a WebSDK link. If the Travel Rule is not applicable to the transaction, the system will return an error response.

📘
Note
The generated token can be used for WebSDK integration.
