How to choose
Can it handle the fax direction I need?
Check whether the service supports inbound faxing, outbound faxing, or both. Then compare delivery tracking and webhook events if your app needs status updates or automatic notices.
Which platforms does it need to run on?
Compare platform support with the environment your app uses. The board lists web, API, Android, Windows, iOS, and macOS support.
Which API protocol should I check?
Compare the API protocol shown for a service with the way your app connects to software. The board includes API protocol as a comparison field.
How do I compare the cost?
Check the free-plan mark, starting price, and included pages together. A free trial is different from a free plan, so look for the pricing details before choosing.
Does open-source code matter for my choice?
If you need to inspect or change the code, check the open-source mark and the service's licence. The board also marks public API availability and free tiers separately.
Questions
What does a fax API do?
A fax API lets an app send or receive faxes. Compare inbound and outbound faxing, delivery tracking, webhook events, and API protocol.
How do I choose a fax API for my app?
Match its platform support and API protocol to your app, then check the fax directions, delivery tracking, webhook events, and included pages you need.
Is a free plan the same as a free trial for a fax API?
No. A free plan is an ongoing plan; a free trial gives temporary access. Check the pricing details to see which applies.
What should I compare in fax API pricing?
Compare the free-plan status, starting price, and included pages. Also check whether a listed offer is a trial rather than a free plan.
What are webhook events in a fax API?
Webhook events are automatic notices when an event happens. Check whether the service supports them if your app needs fax status updates.
