Transaction request

Transaction request API specification

Generate 🔓

To create a transaction request as a dApp, you will need to provide a sign in token and a transaction.

A partial transaction is a transaction with the TransactionSkeletonType format specified in the library Lumos. You need to attach the necessary fields that you want your transaction to have so that it can be processed by the API.

Each transaction request has 7 days to be signed or rejected before it expires.

Remember that to create a transaction request successfully you need to provide a signed sign in token. If the provided token is not signed your request will be rejected.

This is a protected call which uses API authentication. See how to implement it in API authentication section.
