A data source (also known as a product catalog, product feed or data feed) is a file with a list of your products and their corresponding attributes structured in a specific way. This file is processed daily to dynamically create Pins from your products. Read more about how a data source works and maintaining a data source in this Help Center article under Data Source Overview.
I uploaded my feed, but it says that the required fields are missing, but I see them there. What's wrong?
The required fields listed in our Help Center under Required fields must be 100% identical. Make sure to check that all letters are lowercase, underscores should be where they are and there are no extra spaces in your column headers.
My feed says 'Under Review' or 'Rejected'. How can I appeal for my catalog?
Why are the filters from the Product Groups greyed out in the UI?
Make sure you create product groups using filters that will always be in your data source. For example, if you create a product group using the brand filter, make sure the brand field of your data source is in use. If the filters you apply to a product group are not sent in the data source, that product group will have a product count of zero. View this Help Center article for more information.
