Export Mailbox

This method exports the entire content of a mailbox. The HTTP method to read data is get.

The basic URL structure is the following one:



Supported formats for this method are zip, tar, tgz


There are different parameters you can add to the URL of this method:

  • fmt – the response format is required.
  • query – the query string is optional.
  • meta – meta files inclusion is optional. If you want to include them, use meta=1. To not include them, use meta=0. If you don’t set this parameter, the default value is meta=1 when you use tar or tgz as response format, while is meta=0 if you choose zip format.
