# Implements the following CURL command:

# curl -X POST https://driver-vehicle-licensing.api.gov.uk/vehicle-enquiry/v1/vehicles \
#   -H "x-api-key: supplied API key" \
#   -H "Accept: application/json" \
#   -d '{"registrationNumber": "ABC1234"}'

# Use the following online tool to generate HTTP code from a CURL command
# Convert a cURL Command to HTTP Source Code
