Brian,
Please see my comments in the same order:
- No API at this time. Please note this feature is a temporary workaround until we release our versioning feature. We are a bit behind as it was planned by end of July. We are still targeting that date, but we had a couple of other upgrades that might impact that date. I will keep you posted on this.
- No API's right now. Would you please elaborate on the use case. I am very curious to understand this "batch jobs" use cases.
- Not exactly sure what you mean by "Add script from an external storage". How do you even do this without the API is one question and also would you please elaborate on what is it that you are trying to expedite or do.
- API usage is depending on a user. Please elaborate on any needs that you may have so we can help find a solution.
