Our verdict on SendFax.me Developer API
SendFax.me Developer API is a paid faxing service for businesses integrating outbound and inbound fax workflows into products, back-office systems, and other applications. Its REST API sends PDF documents, retrieves individual fax status, lists sent and received faxes, and provides inbound fax records. Bearer-token authentication supports API access, while signed lifecycle webhooks can report fax events. The product is aimed at teams that need straightforward fax functionality without a recurring subscription structure.
Pricing uses one-time credit packs. The Starter plan costs $10 one time and includes $15 of credit at approximately 6.7¢ per US page. Growth costs $50 one time and includes $100 of credit at approximately 5.0¢ per US page. Scale costs $200 one time and includes $500 of credit at approximately 4.0¢ per US page. This structure fits occasional or variable faxing better than a fixed monthly plan, while the higher tiers reduce the approximate per-page rate. There is no free plan.
The API covers core delivery operations with status retrieval, sent and received fax lists, signed lifecycle webhooks, automatic refunds, and one retry for failed faxes. The published payload limit is 15 MB per PDF, which matters for document-heavy workflows. SendFax.me is a good fit for teams wanting simple REST-based fax sending and receiving with pay-as-you-go credits. Organizations needing broader platform or integration coverage should consider alternatives with a wider ecosystem.
