Searching for an event action with a subscription

This example queries an event action by filter:

{
  eevExternalEventActions(
    repositoryIdentifier: "<objectStoreSymName>"
    filter: {
      eevExternalEventReceiverURL: "<receiverURL>"
      #or by
      # eevReceiverRegistrationIdentifier: "<registrationIdentifier>"
      #
      #if both specified then it is AND
    }
    pageSize: <N>  #integer pageSize
    )
  {
    externalEventActions {
      name
      progId
      eevExternalEventReceiverURL
      eevReceiverRegistrationIdentifier
      isEnabled
      cmTransactionTimeout
      subscriptions {
        subscriptions {
          name
          isEnabled
          isSynchronous
          subscribedEvents {
            className
            eventClass {
              className
              symbolicName
            }
          }
          eventAction {
            name
          }
        }
      }
    }
    pageInfo {
      totalCount
      token
    }
  }
}

You can also use the token, if applicable, to get more:

{
  eevMoreExternalEventActions(
    token: "<token>"   #pass in the token
    )
  {
    externalEventActions {
      name
      progId
      eevExternalEventReceiverURL
      eevReceiverRegistrationIdentifier
      isEnabled
      cmTransactionTimeout
      subscriptions {
        subscriptions {
          name
          isEnabled
          isSynchronous
          subscribedEvents {
            className
            eventClass {
              className
              symbolicName
            }
          }
          eventAction {
            name
          }
        }
      }
    }
    pageInfo {
      totalCount
      token
    }
  }
}
