What Integrations and Developer Tools Does Fax.Plus Offer?

Fax.Plus connects to your existing tools in three ways: native integrations for Google apps, Microsoft tools, Slack, and Zapier; a programmable Fax API for embedding faxing into your own software; and extended workflows such as Email to Fax, fax broadcasting, and MFP (multifunction printer) integration. If your goal is to avoid switching to a separate fax portal, at least one of these paths will usually fit — the right choice depends on whether you want a no-code connection, an automated workflow, or custom code.

Native integrations: fax without leaving your daily apps

These options require no development work. You connect your Fax.Plus account to a tool you already use, then send or receive faxes from inside that tool.

The practical value here is workflow continuity: a document you are already viewing or discussing can be faxed without exporting it and logging in elsewhere. For example, if your team handles client paperwork in Google Drive and coordinates in Slack, the Google and Slack integrations keep the fax step inside the same conversation.

Fax API: embed faxing into your own software

The Fax API is the developer-facing option. It lets you customize faxing for your needs — meaning you can build send and receive fax capability into a product, internal system, or customer portal rather than directing users to a separate interface.

Use the API when:

• You are building an application that must send faxes as part of its own workflow (for example, a patient-intake or claims system).
• You need fax events to trigger actions in your own backend.
• You want faxing to appear as a native feature of your product, not a third-party detour.

The API is listed alongside the other integrations as a core offering, so it is a supported path rather than an afterthought. If you are evaluating it, confirm your specific requirements — volume, document formats, and how received faxes should be delivered — against the API documentation before committing.

Extended workflows: Email to Fax, broadcasting, and MFP

Beyond app integrations, Fax.Plus supports several ways to fold faxing into existing routines:

• Email to Fax — send and receive faxes from email, so staff who live in their inbox never open a separate tool.
• Fax broadcasting — send one fax to many recipients, useful for notices, announcements, or bulk document delivery.
• MFP integration — connect office multifunction printers so a physical document can be faxed from the device your office already has.
• Print to Fax — fax from any app's print menu, which covers software that has no dedicated integration.

These are the options to reach for when the constraint is not "which app" but "which habit." A clinic that scans at the front desk, for instance, is better served by MFP integration than by asking staff to upload files to a web portal.

How to choose

• No technical resources, want speed: start with the Google, Microsoft, Slack, or Zapier integration that matches your stack.
• Need faxing inside your own product or a regulated workflow: evaluate the Fax API.
• Faxing is tied to physical documents or email habits: use MFP integration, Print to Fax, or Email to Fax.
• Sending the same document to many recipients: use fax broadcasting.

Platforms mentioned on the site include a web app, desktop app, Android app, and iOS app, so integrations sit alongside direct access rather than replacing it. For organizations with compliance obligations, the site also positions Fax.Plus as a HIPAA-compliant service with enterprise options — worth confirming against your own regulatory requirements before rollout.
