Get Notification Data

When sending notifications with ReturnMode as RESUME, the response will be a RequestID that you can use to get the notification data.

This service will return information about the number of notifications sent, processed and processing.

POST variables

  • HASH: Hash of the company where the template is registered
  • ANNAEXEC: The generated IV, which will be used to encrypt the values of other variables
  • SentId: The generated ID when sending notifications in ReturnMode = RESUME


public static string Execute_WebService()
  string DecKey = "DECRYPTION_KEY";
  string EncKey = "ENCRYPTION_KEY";
  string Hash = "COMPANY_HASH";

  // Generate new IV

  byte[] IVArray = auxTdes.IV;
  string IV = Convert.ToBase64String(IVArray);

  string sentId = "NOTIFICATION_ID";
  string sentIdEncriptado = Encrypt3DES(sentId, EncKey, IV);

  dadosPost += "&ANNAEXEC=" + Uri.EscapeDataString(IV);
  dadosPost += "&sentId=" + Uri.EscapeDataString(sentIdEncriptado);
