Step 1: Create an Infusionsoft custom field in Infusionsoft for your data to get mapped to in Revenue Conduit. Here is Infusionsoft's documentation on how to perform this task http://help.infusionsoft.com/userguides/get-started/create-custom-fields/create-custom-fields
Step 2: Map the custom field created in Infusionsoft to the Revenue Conduit admin portal here https://admin.revenueconduit.com/users/login. Once your logged in you can click on the Infusionsoft tab and then on the Field to Field sync tab. Underneath the dropdown for the store fields, select the field from your store you would like to map. Under the Infusionsoft field, select the field that you created in Infusionsoft for the store data to be deposited and then click add.
Step 3: To see where the field will reside, you can select any contact record page in Infusionsoft and go to it. In the top row of blue tabs, you will see one titled Custom Fields. If you click on the custom fields you will see all the fields you created in step 1 and this is where the information will reside.
