Expected Output: status=success

Look into jq. It is a very handy json parser.

If you want to extract just the status you can do something like:

jq -r '.status' response.json

# output
success

You can format your output as well to follow the results you want.

jq -r '"status=\(.status)"' response.json

# output
status=success
