What is the Postman Console Used For?

The Postman Console is essentially a developer console designed specifically for working with APIs within Postman. It functions similarly to the consoles you might find in web browsers like Chrome or Firefox, but with features tailored to debugging and analyzing API interactions.

Debugging API Requests

The Postman console displays detailed information about each request that is sent. It will include:

Inspecting Script Output

The Postman console displays the output of these scripts, allowing developers to verify that the scripts are manipulating data or handling tasks correctly before the request is sent.

Verifying Certificates

The Postman console can be used to confirm that the correct SSL certificate is sent to the server, ensuring secure communication and avoiding potential certificate-related errors.
