Troubleshooting WhatsApp API Error 132012: Template Parameter Format Mismatch

​Error 132012 occurs when the variable parameter values in your API request do not match the format specified in your approved message template and you get the error message, “Variable parameter values formatted incorrectly.” Ensuring the proper formatting of parameters is crucial for successful API calls.

Understanding the Problem

Message templates on the WhatsApp Business Platform include variables (e.g., { {1} }, { {2} }) to personalize messages. Each variable must adhere to a specific format based on its intended use (e.g., text, media, etc.). If the API request contains variables in the wrong format, the platform rejects the request.

Steps to Resolve

  1. Check the Template Guidelines

    • Review the approved message template in WhatsApp Manager.

    • Identify the variable placeholders (e.g., { {1} }) and confirm their expected data types (e.g., text, image, video).

  2. Format Parameters Correctly

    • Ensure each variable value in the API request matches the expected format.

    • For example:

  • Text: "text": "John Doe"

  • Media: "type": "image", "link": "https://example.com/image.jpg"

3. Correct the API Request

  • Adjust your API call to include the correctly formatted parameters.

By following these steps, you can easily resolve error 132012 and send messages using properly formatted template parameters. For more troubleshooting tips related to WhatsApp Business API check out our other blogs at heltar.com/blogs.
