Take the end user to a Shutterfly User Experience. That is, take the user's Web browser to a workflow on the Shutterfly Web site, usually a workflow to create a personalized Shutterfly product.
The protocol has two variations; your application may use one or the other, at different time:
Single Resource may be viewed as a simplified version of Multiple Resource.
Application ID and call signature are required. Please see Call Signature documentation for more details.
With this variation, your application constructs a 'start URL' like the following:
http://www.shutterfly.com/go2ue/start.sfly?target=xxxx&resourceHref=xxxx
The target and resourceHref are variables. Your app sends the user's Web browser to the constructed URL by means of a link, a redirect, or whatever you prefer. The user will see a workflow on the Shutterfly web site, and interact with it to complete the desired work.
The URL parameters have the following meaning:
Example (before URL encoding, and all on one line):
http://www.shutterfly.com/go2ue/start.sfly?target=OP &resource=http://ws.shutterfly.com/userid/00001234567/albumid/00005678
Note: This is a simplified example. You must supply authentication parameters, and a Call Signature as previously mentioned.
With this variation, your application can specify multiple resources to the desired Shutterfly UE. For example, you could pass multiple album or image URLs, or a mixture, to the OP (OrderPictures) workflow.
Begin by storing your target and resource parameters in the UE Parameter API. That API will construct the 'start URL' for you, telling you what it is. (See its documentation for details.) Your app sends the user's Web browser to the constructed URL by means of a link, a redirect, or whatever you prefer. The user will see a workflow on the Shutterfly web site, and interact with it to complete the desired work.
The user ends the Shutterfly workflow by closing her browser. There is no callback to your site or application. If you would like the user to continue with your site or application when she is done with Shutterfly, open the Shutterfly workflow in a separate browser window.
