Documo Fax API is a programmatic fax service for healthcare providers, health-tech companies, hospitals, health systems, and software vendors. It supports inbound and outbound fax workflows through a REST API, allowing applications to send faxes, receive documents, track delivery status, and respond to failed transmissions. Its healthcare focus includes HIPAA compliance on the listed plans, while integrations cover EHRs, EMRs, healthcare platforms, custom applications, and intelligent document processing workflows.

The plan structure separates basic cloud faxing from API-enabled use. Solo Cloud Fax includes 300 pages per month, one fax number, one user, and HIPAA compliance, but the listed highlights do not include API access. Business Cloud Fax adds API access, 1,500 pages per month, five fax numbers, and 10 users. Enterprise Cloud Fax expands capacity to 6,000 pages per month, 10 fax numbers, and 50 users. The Custom Platform includes fax, intelligent document processing, EHR integration, developer APIs, and dedicated account management. A 14-day trial is available, and the service does not include a free plan.

For integration teams, the feature set extends beyond basic transmission. Webhook notifications cover inbound and outbound fax events, delivery-status tracking and metadata logging support operational visibility, and endpoints handle document downloads and resends. Cover-page generation and scheduled sending add workflow controls, while the sandbox provides a path for integration testing. Documo also provides code examples for cURL, Ruby, Python, PHP, and Node.js. It suits teams that need high-volume fax capacity and healthcare workflow integration; smaller users needing only basic cloud faxing may find the API-oriented plans broader than necessary.
