How To Buy
We will go through the entire process and buy an item via API. In particular, we will buy a 'Brainstorm' Magic: the Gathering card from the 'Commander 2018' expansion set. We will:
- Find the Product
- Add the Product to the Cart
- Purchase the Cart
You can also use our How to buy Postman Collection .
The 'Commander 2018' expansion set has id 8.
You can look for expansion set ids by searching on the table below, or you can use our
GET https://api.cardtrader.com/api/v2/expansions
endpoint.
Find Product
We call GET https://api.cardtrader.com/api/v2/marketplace/products?expansion_id=8
to get the list of Products for sale. The 'Commander 2018' expansion set has id 8.
The result json is an object grouped by blueprint id. Each object is an array of Products. Search in the json for the specific Product you want to buy. Each Product has its own price, condition, vendor, available quantity, and so on.
Here we will buy the Product with id 110419919.
This is the Product we are looking for - a near mint, English, 'Commander 2018' Brainstorm for 40 cents.
If you know that the Brainstorm card is the blueprint with id 327, you can also directly fetch the products using that blueprint_id. Use blueprint_id=327 as parameter.
You can get the list of blueprints and the ids by using this API call.
