Create thousands of discount codes for AppSumo in FluentCart

This query connects to the FluentCart REST API and creates a hundred 100% discount codes at one go.

Execute this query multiple times to create the 10.000 codes required to run an AppSumo campaign.

You must provide:

The username and application password to connect to the FluentCart REST API, via variables $wpUsername and $wpApplicationPassword
The FluentCart store's domain, via variable $fluentCartDomain
The product variation(s) to be redeemed by that code, via variable $productVariationIDs

The generated discount code will be a random string. You can prepend a string to the code (via variable $codePrefix), indicate how long the code will be (via variable $codeLength), and customize the name of the discount code (via variables $discountNamePrefix and $firstRecordNumber) to search for it in the FluentCart dashboard.

Collect all the newly-created discount codes by providing a $postId, then all codes will be appended at the end of that post.
