Please note that RDFI ACH, Wire Transactions, Internal Transactions and Card Transactions are transactions that cannot be created by the API as by the very nature of the transaction, the user accounts receive them vs create them via the API.
Go to Transaction Object Details to see all the required and optional body parameters allowed during transaction creation. Following are a few examples of various types of transactions and how to create them:
Create Transactions between Nodes

Creating SRN Transactions
SRNs allow you to transfer funds from a CRYPTO-US account to an external wallet address. Currently, Synapse only supports bitcoin, ethereum and ethereum_dai. 
SRN stands for System Resource Name. Here it's being used to define an external payment address that is not created or managed by Synapse. Currently it stands for bitcoin and ethereum wallet addresses, but later can be used for payment gateways like PayID.
