# Documents

**Documents** can be created for a given client for the following purposes:

* Secure and centralised document storage.
* Perform checks such as [**Document Checks**](https://docs.complycube.com/api-reference/check-types/document-check) and [**Identity Checks**](https://docs.complycube.com/api-reference/check-types/identity-check).

The documents API allows you to create, update, retrieve, upload, and delete documents. You can fetch a specific document or retrieve a list of all your documents.

{% hint style="info" %}
To upload an image attachment, you first have to [**create a document**](https://docs.complycube.com/documentation/api-reference/core-resources/create-a-document#create-a-document) object, then [**upload an image attachment**](https://docs.complycube.com/documentation/api-reference/core-resources/documents/upload-image-attachment).
