REST API Postman collections (Spot)
Postman is a popular API test environment that allows implementing and testing REST API endpoints.
Postman provides the HTTP networking to connect to the REST API, allows the HTTP headers and GET/POST data to be customised, and allows for custom code to be executed using a JavaScript variant.
Predefined implementations can be imported into Postman via collections (essentially a JSON file containing the configuration and code for each API endpoint).
The following are sample Postman collections for our spot REST API:
Note that the above collections are intended as a demonstration of API usage, hence they do not implement every possible input parameter. Additional endpoints and parameters can be added to the collections by reviewing the appropriate API documentation and using the provided endpoints/parameters as examples.
For quick reference, the following is an example of the JSON content within a Postman collection:
