# BuildTokenSwap

### Description

This endpoint returns the transaction detail that is needed to perform the actual swap, based on information obtained in the **Get Exchange Rate** endpoint. This endpoint will build a transaction for you, which afterward you or your user needs to execute. Each item in the response array needs to be taken, enriched with the relevant signing method and submitted against the endpoint:\ `/api/transactions/execute`
