Multisig contract transaction via api/apps

[wottpal]

Hey,

I have a set of scripts for composing & executing contract transactions via contract.tx.method. But my current contract is governed by a multisig, which means certain tx's need to be performed on behalf of that. I know how to initiate & approve multisig tx's in polkadot-js/apps – but not withinapi/api-contract.

My idea was to (a) initiate it in my scripts as I usually would, export the call data (as hex or bytes), and use this to (b) approve it in polkadot-js/apps (doesn't need to happen within the script). But I neither know how to do (a) on behalf of a multisig nor do I know (b) how to export the call data.

It would be awesome to get some help on this, @jacogr.
