Hi there! You would need to write custom code to integrate the bookstore’s API with the WooCommerce REST API. An API is essentially an interface for interacting with an application via another application. So the bookstore has an API, and WooCommerce has an API, and you need to build the “connector” to get these two APIs to talk to each other, taking the data that the bookstore sends and giving it to WooCommerce in a way that it understands.
This is a fairly complex development topic. I’m going to leave it open for a bit to see if anyone is able to chime in to help you out.
I can also recommend the following places for more development-oriented questions:
- WooCommerce Slack Community: https://woocommerce.com/community-slack/
- WooCommerce FB group: https://www.facebook.com/groups/advanced.woocommerce/
For just uploading the products by hand, there are a few ways you can do that. Since it sounds like manually entering everything is off the table, you could use a product importer like our built-in Product CSV Importer and Exporter. This would allow you to enter the product data into a spreadsheet and then upload that, which might be easier than writing an API interface.
We haven’t heard back from you in a while, so I’m going to mark this as resolved. Feel free to start a new thread if you have any further questions!
