You need a valid API Key to send requests to the API endpoints. You can get your key by clicking on this link.
Response to every request is sent in JSON format. In case the API request results in an error, it is represented by an "error": {} key in the JSON response.
The request method (verb) determines the nature of action you intend to perform. A request made using the GET method implies that you want to fetch something from Postman, and POST implies you want to save something new to Postman.
The API calls will respond with appropriate HTTP status codes for all requests. Within Postman Client, when a response is received, the status code is highlighted and is accompanied by a help text that indicates the possible meaning of the response code. A 200 OK indicates all went well, while 4XX or 5XX response codes indicate an error from the requesting client or our API servers respectively.
