How do I import a large number of subscription options into my store?

TODO: Write ourselves an import in subscriptions and detail how to use the command line to import a given csv file. Related, document API adding.

The easiest solutions here will be writing a custom importer that fits your specific store setup. You can review the user manual from page 32 onward for ways to use PHP, REST/SOAP, or GraphQL to handle these solutions.

Why can't we import the data via Magento's own product import?

The way that we must handle subscription information is rather complex. While we did try and allow for the use of Magento's importer, it has not been successful for various reasons. We recommend using a script to parse your CSV file to import using one of the methods as noted above in the user manual.
