public final class SendTransaction extends APIServlet.APIRequestHandler
Sends a transaction to some peers. Similarly to BroadcastTransaction, the purpose of SendTransaction is to support client side signing of transactions. Unlike BroadcastTransaction, does not validate the transaction and requires adminPassword parameter to avoid abuses. Also does not re-broadcast the transaction and does not store it as unconfirmed transaction. Clients first submit their transaction using CreateTransaction without providing the secret phrase.
In response the client receives the unsigned transaction JSON and transaction bytes.

The client then signs and submits the signed transaction using SendTransaction

The default wallet implements this procedure in nrs.server.js which you can use as reference.

SendTransaction accepts the following parameters:
transactionJSON - JSON representation of the signed transaction
transactionBytes - raw bytes composing the signed transaction bytes excluding the prunable appendages
prunableAttachmentJSON - JSON representation of the prunable appendages

Clients can submit either the signed transactionJSON or the signed transactionBytes but not both.
In case the client submits transactionBytes for a transaction containing prunable appendages, the client also needs to submit the prunableAttachmentJSON parameter which includes the attachment JSON for the prunable appendages.

Prunable appendages are classes implementing the Appendix.Prunable interface.
