Attachment API

Attachments

Using the Mingle Attachment API files can be uploaded to cards and wiki pages as attachments. Existing attachments can also be accessed or deleted from cards or wiki pages. Card attachment resources are located by issuing a GET request to the server with the card's number as a parameter. Wiki page attachment resources are located by issuing a GET to a server with a wiki page's identifier.

Please keep in mind that in many other parts of the system, the system assigned identifier, id, is used to identify a card. Attachments identify cards by number rather than by id. If you specify a card id rather than a card number, you may end up updating the wrong card, and damage your data.

Structure of an attachment resource

The structure of the attachment resource, and its attributes are described below, along with their data type. Also included with each attribute is whether you are allowed to update the value.
