In order for StoreYa to launch Google Shopping and Remarketing campaigns for your Magento store, we will need you to provide us with API credentials, so we can generate the relevant feeds for you.
Before creating an API user, one needs to create an API role.
Login to the Magento Admin Panel and navigate to System > Web Services > SOAP/XML-RPC - Roles.
This page lists the current API roles. If there are none listed yet, click on Add New Role.
Every role needs a name. This can be anything. Just make sure it is descriptive enough for you.
Select "All" or "Custom" and then click on the "Save Role" button on the right.
ii. Step two: Create a new API User
Once your role is created, you can add a user that makes use of this role.
Click: System> Web Services> SOAP/XML-RPC - Users
Click "Add new user" (on your right hand side)
The fields First Name, Last Name and Email just need to be filled in with any value you like. Make sure the User Name and Api Key are secure enough.
Once finished, click "Save user" on the right;
Click "User Role" on the left;
Choose the role created earlier;
Click "Save User" on the right;
Now you should be able to see a green alert on the left, stating that the user has been saved. In order to use the API you have just created, you will need to provide us only with the API username and the API Key.
