Step by step tutorial for leveraging JSON-RPC API?

Question

I've tried several methods to access json-rpc api for multichain but hit a hurdle every way I go. Has anybody come across a clean tutorial for how to integrate this?

For instance when I tried to follow the steps here (which I assumed was ok due to multichain being backward compatible with bitcoin-core): https://www.youtube.com/watch?v=ARL_PvDEBtU, I could not connect to my chain and received either 401 or 403s despite having allowed rpcallowip=0.0.0.0. Or does anybody have sample code leveraging one of the recommended wrappers (preferably php or javascript)? Just quite out of options

Answer 1

You need to set rpcallowip=0.0.0.0/0 if you want to allow connections from anywhere (not recommended for any real deployments).

You can also try the libraries people have created (in many languages) for using the MultiChain API - they are listed at the bottom here: http://www.multichain.com/developers/
