How to send JSON with curl including variables in the payload?

To send a POST request using curl and include a JSON payload, you need to ensure that the formatting of the JSON string is correct, especially with the quotes. Below is the corrected curl command with appropriate escaping for quotes:

curl -X POST -H "Content-type: application/json" --data "{\"content\": \"User = %username% Ip = %ip% time = %time% date = %date% os = %os% Computername = %computername%\"}" %webhook%

Breakdown:

• We are using -X POST to specify that we are making a POST request.
• The -H flag sets the header for content type to application/json.
• The --data flag contains the actual JSON payload:
  • The outer quotes for --data are double quotes.
  • Inside the JSON, we escape the double quotes around the keys ("content") and values using \.
• %webhook% should be replaced with your actual webhook URL.

Important:

Make sure that the shell you are using is capable of parsing escaped quotes correctly. If you are using Windows Command Prompt, you might need to adjust the escaping accordingly.
