getDeliveries method
Will get a collection of PcoWebhooksDelivery objects (expecting many)
using a path like this: https://api.planningcenteronline.com/webhooks/v2/subscriptions/1/events/1/deliveries
Implementation
Future<PcoCollection<PcoWebhooksDelivery>> getDeliveries(
{PcoWebhooksDeliveryQuery? query}) async {
query ??= PcoWebhooksDeliveryQuery();
var url = '$apiEndpoint/deliveries';
return PcoCollection.fromApiCall<PcoWebhooksDelivery>(url,
query: query, apiVersion: apiVersion);
}
