processWebhook method
ProcessWebhook is called by the external SCM for notifying of events.
request - The metadata request object.
Request parameters:
parent - Required. Project and location where the webhook will be
received. Format: projects / * /locations / * .
Value must have pattern ^projects/\[^/\]+/locations/\[^/\]+$.
webhookKey - Arbitrary additional key to find the matching repository
for a webhook event if needed.
$fields - Selector specifying which fields to include in a partial
response.
Completes with a Empty.
Completes with a commons.ApiRequestError if the API endpoint returned an error.
If the used http.Client completes with an error when making a REST call,
this method will complete with the same error.
Implementation
async.Future<Empty> processWebhook(
  HttpBody request,
  core.String parent, {
  core.String? webhookKey,
  core.String? $fields,
}) async {
  final body_ = convert.json.encode(request);
  final queryParams_ = <core.String, core.List<core.String>>{
    if (webhookKey != null) 'webhookKey': [webhookKey],
    if ($fields != null) 'fields': [$fields],
  };
  final url_ =
      'v2/' + core.Uri.encodeFull('$parent') + '/connections:processWebhook';
  final response_ = await _requester.request(
    url_,
    'POST',
    body: body_,
    queryParams: queryParams_,
  );
  return Empty.fromJson(response_ as core.Map<core.String, core.dynamic>);
