User flow begins with fetching quotes, which returns a list of quotes for the given input and output assets, along with the steps involved in the transaction. Quotes are by default sorted via best output and contains a scores object and tags to determine fastest/cheapest/best output routes.
After fetching quotes, you can create a transaction using the selected quote by passing in the routeId of the quote.
Call this api with routeId and stepId of individual steps to get the transaction data to execute.
After user signs and submits the transaction on chain, check the status of the transaction by passing in the signature hash of the transaction.
You can also check the status of a transaction using WebSockets. This can provide faster and almost realtime updates on the status of a transaction.
Note: this feature is in active development and will be generally available soon. Contact us to get access to this feature.
A simple 1 step endpoint is being worked on where a request directly gives you a single quote in response along with array of transaction data to execute to complete the transaction
