If you're store is built on Shopify your best option is to integrate directly with Marpipe and manage your advertising feeds through the platform.
Installing the Shopify App
First, open feed settings and select Shopify as the feed source
This will take you to the Shopify app store page for the Marpipe plugin. Make sure you are logged into the correct account and click install.
After installing the app you will be redirected back to Marpipe and may be prompted to select an account if you belong to more than one.
After continuing, the system will start to pull in your Shopify data and build the source feed in Marpipe.
Once the upload is complete you will see the window change to show your store name.
If you already had a source feed you will need to click the button to fully replace the existing source feed with the Shopify integration. If this is the first feed in the account you are already good to go.
Now you can go the Inspect source feed section and see all of the source feed data that has been automatically mapped.
