Betting bot for customers

[Sid7]

I am looking to create a bot that places bets for customers based on pre-defined criteria.

What's not clear to me is how authentication would work, since the betting process is automated. i.e. I don't want the customer to place any bets manually.

Easiest solution is for my server side application to store customer's Betfair credentials locally, but no sane customer would want that.

Is there a standard protocol for this kind of requirement?

Any pointers would be greatly appreciated.

Thanks.
