Can I attach files to tickets using the API?

Question 

 Can I attach files, such as photos, to a ticket using the Zendesk API?

Answer

Yes. When a file is attached to a ticket, and if the account requires authentication to download attachments, the attachment's visibility becomes restricted to only users with access to the ticket. Until the attachment is associated with a ticket, any authenticated user can view an attachment using its content_URL. The attachment's token expires after three days.

Note: If step 2 below is not completed, the uploaded files will be deleted and will appear missing (returning a 404 not found error) when the upload token expires.

Procedure: 

1. Use our Uploading files API, which returns a token.
2. Include the token in a ticket comment by the uploads array while creating or updating a ticket.

Example:

{
  "ticket": {
    "comment":  { "body": "See screenshot.", "uploads":  ["vz7ll9ud8oofowy"] }
  }
}
