APIs​

Retrieve JSON data for analysis by making HTTP requests to different APIs (clouds). Explore and:

  • Evaluate prominent APIs from Google or ChatGPT
  • Interact with IBM Watson API and Elasticsearch
  • Develop and streamline ETL processes using Informatica or IBM Datastage
  • Conduct experiments with CI/CD processes on Microsoft Azure.

Syntax of HTTP-Request​

HTTP requests follow this syntax:

To write a request, make sure you use the following 2 mandatory elements:

  • Name of request (will also be used for the script). Before the request title, you need to put three hashtags
    ### name of request
  • HTTP method und URL:
    GET, POST, PUT or DELETE URL

Optionally, you can include:

  • HTTP header(s):
    header name: header value ...
  • body, This is the textual content, for example, in JSON format.
    Inside the request, prepend the request body with a blank line.

In URL, headers and body can be included the variables enclosed in double curly braces: {{variable}}. See next topic HTTP Variables.

Single-line comments, preceded by a double slash, are allowed anywhere.


//comments

Before several requests, you can specify the name of the request group. This allows, when there are a large number of requests, to work conveniently with the structure, including quickly finding requests. The name of the request group should be preceded by one or two hashtags.


## Name of the request group

Example HTTP-Request​

### example request name

GET  https ://dummyjson.com/carts


Accept: application/json
