Create Transactions

To programmatically create a transaction, call the Create Transaction API by sending a POST request to the /api/v1/transactions endpoint.

In the request, specify the origin vault of the transaction, the designated signer (api_signer for programmatic transactions), the type of the transaction, and the details of the transaction.

Request signing

Since creating a transacton is a sensitive operation, it requires signing the request. The following examples demonstrate how to create and sign a basic bitcoin transfer in different programming languages. Learn more about request signing.
