alias fastly="curl \
    -H 'Fastly-Key: <api_key>' \
    -H 'Content-Type: application/x-www-form-urlencoded' \
    -H 'Accept: application/json'"

Create Fastly Service

-d 'name=<unique_app_name>'

Add a domain

fastly https://api.fastly.com/service/<service_id>/version/1/domain \
-d 'name=<unique_app_name>.global.ssl.fastly.net'

Add WireMock backend

fastly https://api.fastly.com/service/<service_id>/version/1/backend \
-d 'hostname=<unique_app_name>.herokuapp.com&name=<unique_app_name>'
