publishfrom VS createrawsendfrom commands

Question

I want to apply steps of normal blockchain process mentioned in https://www.multichain.com/developers/external-key-management/  [create transaction - sign transaction - broadcast transaction ] but somehow I am confused of using commands publishfrom or createrawsendfrom in the first step [creation].

Answer 1

If you want to use an external private key, you cannot use the publishfrom API, because this builds and signs the transaction in a single step, which is not possible if the private key is not in the node's wallet. Instead you should use the createrawsendfrom API as explained in that tutorial.
