Template Comparison

Updated: Nov 14, 2025
You can compare two templates by examining how often each one is sent, which one has the lower ratio of blocks to sends, and each template’s top reason for being blocked.

Requirements

    A User or System User access token.The whatsapp_business_management permission.

    Limitations

      Only two templates can be compared at a time.Both templates must be in the same WhatsApp Business Account.Templates must have been sent at least 1,000 times in the queries specified timeframe.Lookback windows are limited to 7, 30, 60 and 90 days from the time of the request.

      Comparing templates

      Use the WhatsApp Message Template > Compare endpoint to target one template and compare it with another.

      Request Syntax

      GET /<WHATSAPP_MESSAGE_TEMPLATE_ID>/compare
  ?template_ids=[<TEMPLATE_IDS]
  &start=<START>
  &end=<END>

      Query parameters

      Placeholder Description
      <WHATSAPP_MESSAGE_TEMPLATE_ID>
      ID of the WhatsApp Message Template to target.
      <TEMPLATE_IDS>
      ID of the WhatsApp Message Template to compare the target to.
      <START>
      UNIX timestamp indicating start of timeframe. See Timeframes.
      <END>
      UNIX timestamp indicating end of timeframe. See Timeframes.

      Timeframes

      Timeframes (lookback windows) are limited to 7, 30, 60 and 90 days from the time of the request. To define a timeframe, set your end date to the current time as a UNIX timestamp, then subtract the number of days for your desired timeframe, in seconds, from that value:
        Subtract 604800 for a 7 day window.Subtract 2592000 for a 30 day window.Subtract 5184000 for a 60 day window.Subtract 7776000 for a 90 day window.

        Response

        Upon success, the API will return a list of WhatsApp Business Template Comparison nodes describing each template’s block rate, number of times sent, and top reason for being blocked.
