HTTP requests
As discussed in the previous section, only the request and response is in JSON format. On
both the client side and the server side, this JSON data (request and response) is parsed by
the SDK or the browser (on the client side) and DynamoDB (on the server side).We can
perform almost all types of DynamoDB operations through HTTP requests. All the pos-
sible operations are listed, and we will discuss them in detail in the last section of this
chapter. Now, let's observe the HTTP request structure. The strength of the REST API can
be easily understood from the fact that most of the SDKs use REST API internally for all
their calls.
Here, I have used Postman (an extension of Google Chrome) to perform the REST opera-
tions. Other than that, many other software options, such as cURL, are also available for
the same purpose.
In the following screenshot, we need to understand the use of the three sections (on the
right-hand side):
