Upload product feeds from partner sites via API in WordPress

There is a website, a course aggregator, you need to upload information on courses to it, here is detailed documentation https://my.advcake.com/stat/api-feed-info on feeds.

Commodity feed - an updatable array with courses and information on them in Json or XML formats

Recapping:

1. There are already products on the site, but nothing has been updated for two years. You need to upload what is already on the site to the table, combine with the necessary feeds, update by key (product ID)

2. In addition, now the products are displayed as regular products, they need to be changed to partner (in WooCommerce there is such a category of goods, you can also update the type of goods through unloading and subsequent import)

3. Next, set up periodic updating of the database of partner products by API (every three days).

4. In the WordPress admin panel, configure the import of new feeds via the link (inserted the link and imported)

5. Configure HTML parsing from landlords (links to landing pages can also be uploaded via API) and their subsequent unification.
