Resending faxes

Sometimes you need to resend a fax. Maybe you sent a copy of the contract last week but it was misplaced. Maybe the order got lost. Now you need to find it, and resend it. Well, we’ve got just the thing: the resend fax operation.

Whichever version of the API you’re using, resending faxes is incredibly easy. In the v2 API simply append the faxID and /resend when making your API call. Further, you can provide a callback URL for us to ping when the fax is complete.

For v1, make an API call to /resendFax with the fax ID and your API credentials. In case you’re wondering, the major difference in functionality between the two versions is that Phaxio will only trigger a callback URL if you have an account-wide callback setup.

But wait, there’s more!

If this is just a once-in-a-while need, you don’t need to make an API call at all! Instead, log into your Phaxio dashboard and, while viewing the fax that needs to be resent, click the Resend button!

But wait, there’s even more!

What if you have a couple of faxes that you want to resend and while you have the faxID’s, you don’t have the time to click a bunch of buttons? Julien, one of the devs here, has the answer for you. With your list of faxID’s, head over to, input your faxID’s and API credentials and click the Resend Faxes button. Voila!

We’re always looking for ways to improve so keep an eye out because we’ve got some great tricks up our sleeves!
