Sending Outbound Faxes via Slack

This article explains out to send an outbound fax message after configuring Slack with etherFAX’s DirectFax Messenger app.


Before reading these instructions be sure that the following prerequisites are met:

  • Slack with DirectFax Messenger added to either the user or a specific channel (enrolled by the user attempting to fax)

  • A ready-to-fax file attachment

Complete Setup & Overview Video

Below you will find a video covering the entire setup process for DirectFax Messenger on Slack


How to Send Outbound Faxes via Slack

  1. With the DirectFax Messenger added to our Slack Channel, or through the DirectFax Messenger app itself, go to the message field and add an attachment. This can be done by clicking the paperclip icon and then adding a file from “Your computer”:

  2. After attaching your file, press the Enter key to submit the attachment to Slack and hover above the message so that you may view the additional actions you can take on the message:

  3. From there, select the “More actions” button (the 3 vertically aligned dots) and choose the “Send as Fax” option:

  4. A pop up will appear where we will input the Recipient Fax Number and the other fields are optional. Fill out the fields as needed (being sure to toggle “Cover Page” to “Yes” if wanting to include a cover page) and then click “Submit”:

  5. Following the form instructions above, you can send up to 10 recipients. And for files that already exist within the DirectFax Messenger enabled channel, you can go from Step 2 onward to send a fax of the same file.

Accepted file types are .docx, .xlsx, .tiff, .pdf, .txt, .html, .jpg, .bmp, and .png

If you receive an error when attempting to “Send as Fax” then it may likely be that you have registered another channel/user with etherFAX, instead of the where you are receiving this message. If this is the case, you will want to follow registration steps to get the specific channel/user registered. Thereafter, you will be able to follow the steps above to send a fax from Slack.
