Faxxing review
A practical free-start fax API with inbound support, signed webhooks, and usage-based pricing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Faxxing is a REST API for organizations that need to send and receive faxes programmatically. Developers can submit fax jobs with JSON and an API key, using PDF URLs or HTML-to-PDF conversion for outbound documents. It also supports dedicated inbound fax numbers, email forwarding of received faxes as PDF attachments, and web access alongside its API. The product is positioned for modern GTM teams and operations in healthcare, legal, government, manufacturing, and B2B settings.
Pricing is structured to support a low-commitment start. The Free account includes 50 outbound pages and requires no card. Pay as you go adds inbound and outbound faxing, webhooks and retries, with no seats, tiers, or minimums; the published pricing wording shows 10¢ per fax and per page. Enterprise adds volume discounts, a BAA, SOC2 reports, a dedicated CSM, and an on-prem connector. This makes Faxxing a sensible fit for teams validating a workflow or managing variable usage, while high-volume buyers should compare the economics of Enterprise pricing.
The strongest technical fit is for workflows that need delivery visibility and event-driven automation. Ed25519-signed webhooks, webhook and SSE delivery-status updates, and fax logs with live status updates provide several ways to follow fax progress. Slack, Apollo, and Notion integrations extend the product beyond the core API. Faxxing should suit teams that value a free entry point and straightforward REST integration; organizations needing higher throughput, deeper platform coverage, or volume-optimized pricing should evaluate alternatives alongside the Enterprise plan.
