    headers

    object

    A JSON object containing key-value pairs, where both keys (header names) and values must be strings. These pairs represent custom headers to be substituted. Please note the following restrictions and behavior:

    • Reserved headers: The following headers cannot be modified:

      • Authentication-Results
      • BCC
      • CC
      • Content-Transfer-Encoding
      • Content-Type
      • DKIM-Signature
      • From
      • Message-ID
      • Received
      • Reply-To
      • Subject
      • To

    • Header precedence: If a header is defined in both the personalizations object and the root headers, the value from personalizations will be used.

    • Case sensitivity: Headers are treated as case-insensitive. If multiple headers differ only by case, only one will be used, with no guarantee of which one.
