Magento Go enables you to integrate your web store with other Web-based applications using web services. Web services are services that share information across networks using standards-based technologies.
In other words, customer, catalog, and sales information can be shared with other Web-based services to help create a more integrated set of tools for your business.
Web services pull information from your web store with the Magento Core API—or the application programming interface. The Magento Core API consists of all the parameters, or particular data requests, that other web services can access from your web store.
Check out a complete reference of the Magento Go API.
When you are integrating third-party web services with your Magento Go store, they must have permission to access your web store data. You can do this by creating a web service user and role.
NOTE: This is optional—selecting a resource will allow full access. Click Save Role.
Once you have a user with a configured role setup, you are ready to integrate third-party web services with the Magento Go platform.
To ensure that it works, fire up your browser and go to your web store. Loading a page from your web store will run the scripts at least once, activating the scripts.
If you experience problems, make sure the code you inserted is corrected and that you have cleared your browser cache before re-accessing your web store.
