## Add attachment

`POST /rest/api/{2-3}/issue/{issueIdOrKey}/attachments` 

Adds one or more attachments to an issue. Attachments are posted as multipart/form-data ([RFC 1867](https://www.ietf.org/rfc/rfc1867.txt)).

* The request must have a `X-Atlassian-Token: no-check` header, if not it is blocked. See [Special headers](https://developer.atlassian.com/cloud/jira/platform/rest/v3/intro/#special-request-headers) for more information.
* The name of the multipart/form-data parameter that contains the attachments must be `file`.

## Download Attachment

`GET /rest/api/{2-3}/attachment/content/{id}`

This endpoint returns the contents of an attachment. A `Range` header can be set to define a range of bytes within the attachment to download. 

If successful, Jira will return a response with the attachment file. You can save the file to your local filesystem or process it in your application as needed.
