# Fax

Welkin Health uses **Notifyre** as the fax vendor. Faxes are accessible from the Inbox in the Care Portal.

***

## Sending a Fax

The **Send Fax** button is available on both the Incoming and Sent Faxes tabs. Clicking it opens the fax sending form with the following fields:

* **Sender** — the fax number to send from. If multiple numbers have been configured, select the desired one from the drop-down list
* **Recipient** — the destination fax number
* **Subject** — the fax title
* **Related patient** — the patient the fax is associated with
* **Attachments** — files to include. Supported formats: JPG, PNG, PDF, DOC, XLS. Maximum 10 files with a combined size of up to 100 MB

By default, you can attach templates created in Designer or upload a file from your computer. If a patient is linked to the fax, you can also select files from that patient's Document Center.

You can preview each file before sending.

**Form actions:**

* **Save** — saves the fax as a draft, accessible in Fax Sent → Draft tab
* **Cancel** — discards the fax
* **Send Fax** — sends the fax immediately

* Phone number (`fromNumber` or `toNumber`)
* Subject

Attachments support the following file formats: `jpg`, `jpeg`, `png`, `pdf`, `docx`. Maximum 10 files with a total size of up to 100 MB.
