Use the new API methods to send messages by template ID, receive callbacks about changing the WhatsApp template category, and consider the new mechanism for debiting funds for AMAU.

Updates​

  • Added new API methods for sending messages by template ID:

    • api/v1/out-messages/whatsapp/template — for sending messages to the WhatsApp channel;

    • api/v1/out-messages/viber/template — for sending messages to the Viber channel.

      Consider the features:

    • Old method
      Previously, only one method was available for sending messages — api/cascade/schedule. This method specifies the content of the message to be sent to the recipient. The content is checked for compliance with the template when the message is sent. There is a risk that the content will not pass verification, in which case the message will either not be sent or will be sent using a different template at a higher cost.

    • New methods
      The new version of the API has two additional methods — api/v1/out-messages/whatsapp/template and api/v1/out-messages/viber/template. Rather than specifying the message content, they use the template identifier templateId to indicate which template the message should be sent to. This eliminates the above-listed risks and simplifies integration.

      warning

      Despite the release of additional methods for sending messages by template ID, we will continue to support the api/cascade/schedule method.

  • WhatsApp
    Changed the mechanism for debiting funds for AMAU. Previously, if there were not enough funds in the account to cover the full AMAU amount, we incurred debt but did not write off the money. Now, if this happens, we will write off the full AMAU amount, even if it results in a negative balance.

    tip

    Consider the new mechanism when sending messages and managing your balance.

  • WhatsApp
    Added a new webhook request about changing the category of the WhatsApp template. Now, if Meta changes the template category, edna Pulse will send not only an email and UI notification about this event, but also a webhook request about changing the template category. Most often, Meta can change the category of a template when registering it.
