# Get documents and photos with their type

There are two types of documents in Dashdoc :

* Documents generated by our solution.
  * These documents are found in the `documents` list in transports data. For example the CMR or the order confirmation document. . Every element of the list is a document, characterized by its `category` (`cmr` and `ldv` for CMRs, `rental` for rental order document, `orc` for Order confirmation, `chc` for Chartering confirmation, and `loading_plan` for loading plan) and the field `file` which is a link to the PDF document.
* Documents, including photos, added by Dashdoc users (through the mobile app, the web app or the API).
  * These are located in the `messages` list in transports data.
  * The `type` field indicates the nature of the document (possible values listed in the API reference).
  * The `document-type` field indicates the use of the document. Possibilities are:
    * CMR (`"document_type": "cmr"`). :warning: if a trucker uploads a photo of a CMR, it will appear here. This CMR will be the unique source of truth for the transport and the PDF document generated by Dashdoc will no longer appear in the `documents` section. There might be a photo uploaded after the pick-up and another after the delivery.
    * Delivery note (`"document_type": "delivery_note"`)
    * Transport order (`"document_type": "confirmation"`)
    * Weight note (`"document_type": "weight_note"`)
    * Invoice (`"document_type": "invoice"`)
    * Washing note (`"document_type": "washing_note"`)
    * Load photo (`"document_type": "load_photo"`)
    * Waste manifest (`"document_type": "waste_manifest"`)
    * Holders swap note (`"document_type": "holders_swap_note"`)
    * Other (`"document_type": ""`)
  * URL to the document file is in the `document` field.
  * ⚠️ Not every message contains a document, there are also messages with only text. Be careful to only import messages with a non-empty `document` field to retrieve photos.
