How can I use variables in curl commands?

You can use shell variables in curl commands by prefixing them with a dollar sign. For example, if you have a variable named url, you can use it like this: curl $url.

Can I use multiple variables in a single curl command?

Yes, you can! Just include them in the command like this: curl -X GET $url -H 'Authorization: Bearer $token'.

What if I want to pass a JSON payload using a variable?

You can do that by using the -d option. For example: curl -X POST $url -d @$dataFile where dataFile is a variable containing the path to your JSON file.

Is there a way to see the full curl command with variables expanded?

Yes! You can use the set -x command in your shell before running the curl command. This will print each command with its expanded variables.
