getPaymentSources method

Will get a collection of PcoGivingPaymentSource objects (expecting many) using a path like this: https://api.planningcenteronline.com/giving/v2/payment_sources

Implementation

Future<PcoCollection<PcoGivingPaymentSource>> getPaymentSources(
    {PcoGivingPaymentSourceQuery? query}) async {
  query ??= PcoGivingPaymentSourceQuery();
  var url = '$apiEndpoint/payment_sources';
  return PcoCollection.fromApiCall<PcoGivingPaymentSource>(url,
      query: query, apiVersion: apiVersion);
}
