Phaxio is built for you.
A modern fax platform for your business
Sending faxes just got super easy.
We provide clear and up-to-date documentation. Also, we have open-source first-party and community-contributed client libraries to quickly get you started.
From startup to Fortune 500, we're the only platform you'll need.
Never worry about having enough phone lines or channels again. Send and receive as many faxes as you need, whenever you need.
Batch & Avoid
Easily batch multiple faxes together and avoid collisions, sending to numbers already in use. Perfect for restaurant ordering during peak hours.
Don't let faxes hang in limbo. With cancel timeouts you're guaranteed your fax request will complete within the timeout you specified.
We never throttle your sent faxes. All faxes are sent as soon as your API call is processed.
Multiple carriers for redundancy and scalability to ensure your fax gets through every time.
Configurable settings for retrying failed faxes due to busy lines and other fax related errors.
Manage faxes, provision numbers and more
