How do I get a string from a curl response for a variable in bash?

Question

The bash script sends a curl. The curl response example is following:

{"code":"2aaea70fdccd7ad11e4ee8e82ec26162","nonce":1541355854942}

I need to get the code "2aaea70fdccd7ad11e4ee8e82ec26162" (without quotes) and use it in the bash script.

Use jq to extract the value from the JSON, and command substitution to capture the output of the command:

code=$(curl ... | jq -r '.code')

The -r (--raw) prints the string directly instead of quoting it as in a JSON.
