REST API

The API package manages matrix headers, product-condition rows and direct customer assignments.

composer require mageb2b/pricesystem-productcustomermatrix-api:*
php bin/magento setup:upgrade
php bin/magento cache:flush

Resource	Base endpoint
Matrix header	`/V1/pricesystem/productcustomermatrix`
Product condition	`/V1/pricesystem/productcustomermatrixattribute`
Customer assignment	`/V1/pricesystem/productcustomermatrixcustomer`

Each resource supports:

GET /:id for one record;
GET /search with Magento search criteria;
POST to create;
PUT /:id to update;
DELETE /:id to remove.

Create the matrix header before its condition and customer rows. During synchronization, remove or update child rows deliberately so stale conditions do not continue matching products.

Use a Magento integration with the Product-Customer Matrix ACL resources. Calculated price operations are documented under Pricesystem REST.
