I am having trouble getting my data feed into the data source for the catalog. I have followed the procedures and keep getting the message: Catalogs doesn't support HTML files. I uploaded the .csv file onto a page on my website accessible to download with a button. Still getting the error message. Please help.
You'll need to host your own data source on an FTP/SFTP server or with an HTTP/HTTPS direct-download link. This needs to be accessible by a user-agent, and cannot require IP or SSH key whitelisting. If you're using a direct download link, there cannot be any extra navigation required for Pinterest to access the file.
Hope you were able to solve it! Let me know if you have any further questions.
