This is my first time posting here. I am an experienced Database Programmer but have done very little with web programming. We have a customer's website that gives a list of possible sales with an Accept button next to each one. The company that accepts the sale first gets it. I would like to write something that reads the line of the sale and if the line matches our criteria automatically click the accept. We already have competitors that are doing this. I don't know where to start to going about having a button on website I do not host to be clicked. I can see the button runs a javascript on the click event from viewing the source but I don't know how I can use that since I do not host that site.

If this isn't the best place for this topic let me know where I might be able to find help with this.
