GET v4/products - Read All

The Products API is used to retrieve and query the VitalSource catalog, which has more than a million titles available. Users can choose specific requests to filter results and also configure paging on how many records are returned per page. With this API you get access to data used by VitalSource to distribute, sell and link content including links to additional resources to retrieve other metadata for use within a users own commerce system.

Best Practice: When creating your catalog on your eCommerce site, utilize the kind and format attributes to display the kind of title (ex: Book, Online Resource or Online Resource Bundle) and the format of the content (ex: ePub or Page Fidelity).

Note: When an item is no longer distributable in your catalog, the distributable attribute will return false for 10 days, then will be dropped off the response.

You can request one to many of these response groups separated by a comma.

Response Descriptions - prices

Each product in a client's catalog can have many prices. Each price has the following attributes:

type Prices have "types," such as digital list price or print list price. When to use which price type as your selling price is dependent on your company's agreements with VitalSource or your direct agreements with publishers. Please work with your assigned customer success manager
value Price in decimal format
currency Supported ISO-4217 currency code By default, the endpoint returns all prices in all currencies for each of the "basic" price types. Individual API keys can be configured to receive additional price types as determined by business need. If a client has any custom pricing, a price type of distributor-price will be returned as an additional price element. 

Note: Not all products and variants have prices in every price type or currency. If you specify a currency the endpoint returns all prices with the specified currencies for the products a client can distribute. If there are no prices in the currency specified you'll receive empty price information.

discount_codes The discount code that can be applied to this product, if applicable
territory Comma separated country codes based on the ONIX 3.0 standard (which is based on the ISO 3166-1 standard). If present, the given price is only relevant to transactions in the stated territories and can not be transacted at that price outside those regions. If empty, you may assume the price is good worldwide.


Response Descriptions - price types

digital-list-price This is the general price from the publisher to a distributor. Your company may or may not add mark-up, depending on your business terms.
print-list-price This is the price the publisher has set for the print product, which can be used for comparison purposes. e.g. "Digital price saves 20 percent over the publisher's list price for the print book."
distributor-price This is a custom price given to your company by the publisher. If present, it supersedes the digital list price.
This is a fixed price to consumer set by the publishers. Your company must transact at this price. No markup or discount on this price is allowed.
catalog-price The catalog price is regenerated weekly from the digital list price. It is designed to reduce intra-week pricing variations and to quantize when those changes happen. This price is designed for brick-and-mortar stores that have to manage physical shelf price tags. Note: Available upon request
ia-agency-price This is a fixed price to student when an institution is purchasing for its inclusive-access program. Your company will not transact at this price. Note: visible to publishers only
inclusive-access-price This is the price to bookstore for products delivered through Inclusive Access programs and Equitable Access programs (unless an equitable-access-price exists, applicable to EA programs only). Typically, the bookstore marks up this price. Note: Requires signing an IA and/or EA agreement.
equitable-access-price This is the price to bookstore for products delivered through Equitable Access programs only. Note: Requires signing an EA agreement.
print-on-demand-price This is the price to purchases an on-demand copy of the digital resource. This purchase has to happen within the VitalSource ecosystem, but may be useful for your company to track. Note: Available upon request
publisher-unique-price This is a "special" price that can have different meanings to different publishers. Your company will not transact at this price. Note: visible to publishers only
recommended-retail This is a to-consumer purchase price good only in VST-powered e-commerce stores. (This is the "store price" in Manage.) Note: visible to publishers only
