Create webhook message based on given fixture
Example:
./manage.py send_webhook_fixture_message \
[--realm=zulip] \
--fixture=zerver/webhooks/integration/fixtures/name.json \
'--url=/api/v1/external/integration?stream=stream_name&api_key=api_key'
To pass custom headers along with the webhook message use the --custom-headers
command line option.
Example:
--custom-headers='{"X-Custom-Header": "value"}'
The format is a JSON dictionary, so make sure that the header names do
not contain any spaces in them and that you use the precise quoting
approach shown above.
