Before you get started:
Pinterest ingests your data source once every 24 hours and does NOT support scheduling or on-demand ingestion.
A maximum of 5 million products per account can be processed
Only one data source is allowed per business account
Starting from your Sales & Orders account:
Navigate to the Feed Tool>Feeds
Scroll down to File Feeds
If you don't have your Pinterest catalog created yet, select it from the drop down menu and then click Generate files. Please allow for anywhere from 5 minutes or more to have the file generated
IMPORTANT: Pinterest will only accept a CSV file so that is the only type available for copying.
From your Pinterest business account:
Before continuing on, be sure to have claimed your Website URL with Pinterest by going to https://www.pinterest.com/settings/claim/.
Click on Add data source
Paste the catalog/feed file URL generated by Sales & Orders into the field designated in the next step
Note that S&O file URLs are NOT password protected
Be sure to select CSV as the file type
Finish by clicking Create Pins
It is important to note that Pinterest will first Validate your catalog.
Additionally, it will take Pinterest anywhere from 1 to 2 days or potentially longer to review your catalog.
