How to integrate another webstie in to yours..

Hi, Im looking for a solution to manage vehicle inventory on a website.. I would like to be able to integrate craigslist, ebay motors, backpage, and autotrader on my website, so that once you have a vehicle in the database you can then send them to multiple places with one click of a button to possibly all of the mentioned above. I want to make it where you can manage and market from one platform...Can someone give me some advice or a direction to start as far as programming this.
Thanks

 

the problem is that some of the platforms require exclusivity

 

What do you mean by that?

 

I think exclusivity means only I can show my contents and nobody else. Some people use RSS feeds to pull contents from other sites. I prefer to go for RSS feeds if a site allows for it.

 

That you cannot list your item on their site whilst its listed elsewhere. Given bids are binding on eBay, how can you list an auction on ebay and also list it for sale directly on CraigList? If the item receives bids on eBay and it subsequently sells on CraigsList prior to the eBay auction closing your are legally bound to the sale on eBay even though you no longer own the vehicle having sold it via CL

 

I think the original poster wants to link to the entry on other sites, instead of having the user create a new entry which causes the kind of legitimate issue you brought up. That's what I understood.
