≡ messages API
≡ Related information
The messages API allows to access and manage the user's messages.
Note
When the term messageId is used in these documents, it doesn't refer to the Message-ID
email header. It is an internal tracking number that does not remain after a restart. Nor does
it follow an email that has been moved to a different folder.
Warning
Some functions in this API potentially return a lot of messages. Be careful what you wish for! See :doc:`examples/messageLists` for more information.

.. api-header::
:label: Parameters
.. api-member::
:name: ``messageId``
:type: (:ref:`messages.MessageId`)
.. api-member::
:name: [``options``]
:type: (object, optional)
.. api-member::
:name: [``data_format``]
:type: (`string`, optional)
The message can either be returned as a DOM File or as a `binary string <https://developer.mozilla.org/en-US/docs/Web/API/DOMString/Binary>`__. The historic default is to return a binary string (kept for backward compatibility). However, it is now recommended to use the :value:`File` format, because the DOM File object can be used as-is with the downloads API and has useful methods to access the content, like `File.text() <https://developer.mozilla.org/en-US/docs/Web/API/Blob/text>`__ and `File.arrayBuffer() <https://developer.mozilla.org/en-US/docs/Web/API/Blob/arrayBuffer>`__. Working with binary strings is error prone and needs special handling:
.. literalinclude:: includes/messages/decodeBinaryString.js
:language: JavaScript
(see MDN for `supported input encodings <https://developer.mozilla.org/en-US/docs/Web/API/Encoding_API/Encodings>`__).
Supported values:
.. api-member::
:name: :value:`BinaryString`
.. api-member::
:name: :value:`File`
.. api-member::
:name: [``decrypt``]
:type: (boolean, optional)

Lists the attachments of a message.
.. api-header::

If a message only includes a part with content type text/html, the method :ref:`messengerUtilities.convertToPlainText` can be used to retreive a plain text version.
Note: A message usually contains only one inline text part per subtype, but technically messages can contain multiple inline text parts per subtype.
