Virtuemart/Checkfront Integration

Checkfront is an online booking platform primarily targeted at adventure experiences, rentals and accommodations. I would like to integrate products from multiple Checkfront accounts into a single Virtuemart store so that customers can purchase products from multiple companies in a single payment. If possible, I would like the following functionalities: 1. Checkfront account holders should be able to add their own products to the master VM store (the VM store will be set up as multi-vendor). Preferentially the product details, fields, variables, content etc. will be created in VM automatically, but if necessary these could be set up manually instead. 2. Products in the VM store should list accurate inventory levels as shown in the Checkfront accounts. This is mandatory as there can be no opportunity for a customer to purchase a product through VM that isn't actually available in the relevant Checkfront account. Additionally, upon starting the booking/reservation procedure the inventory should be held for a short period of time to prevent overbooking of product. 3. When a product is purchased in VM a matching reservation for the product should be created automatically within the related Checkfront account and trigger the automatic Checkfront functionalities (i.e. notifications). 4. Any modifications/cancellations that are made to a booking in Checkfront should be reflected in the VM reservation. Payment for purchased products does not need to be passed to the Checkfront account holders. This will be managed separately. Only customer details/variables, inventory, status etc. will need to pass between VM and Checkfront. Please review the available Checkfront API information here: [login to view URL]
