We want to add an option (another category) to our customers who work with hp printers on their website, so their customers will be able to design a wallpaper on hp wallart website and then will make an order of it on our customer's e commerce website, we provide websites and mobile apps to print shops and looking for an outsource developer to do some of the work on that project.
We are looking for someone who will build us the oauth integration with hp In a way that it will be on a server that will serve all of our customers, kind of a "black box" that will know how to communicate with our websites and with hp.
It will know what details to get and post in order to redirect users from the e commerce website to the hp wallart designer tool,
then when the user will finish his designing there it will know from where he was coming and what details to send back in order to complete the order in the e commerce shopping cart.
When the user goes back to the cart and pay a pdf or something that hp exports will be send to the website's company somehow.
The api and integration is oauth, hp wants the website owner to be the provider of the authentication..
I "printed to pdf" the api guide from hp wallart website [url removed, login to view] because in order to access their guides online you have to be registered, so it is attached.
I am attaching a zip with php files that they give as an example for the oauth (they have a .net one as well if needed) and a flow diagram that explains the logic process as well.
