Updox is a healthcare communication and patient engagement platform for in-person and virtual care, offering a single inbox for secure/direct messaging, electronic fax, document management, patient reminders, forms, and telehealth video chat. Updox is integrated with 100+ EHR and pharmacy management systems and has been a part of EverCommerce (NASDAQ: EVCM) since its December 2020 acquisition.
APIs.json: https://raw.githubusercontent.com/api-evangelist/updox/refs/heads/main/apis.yml
Updox exposes a documented but partner-gated public API, not an open self-serve developer program:
- The API is a POST-based "IO" API surfaced through an IO Docs explorer at updoxqa.com/api/newio (base
https://updoxqa.com/api/io), plus a knowledge base at help.updox.com. - Authentication is tiered:
applicationId+applicationPassword, thenaccountId, thenuserId, depending on the action. Credentials are issued by Updox to partners (EHR, pharmacy, integration vendors) rather than created via open signup. - Event delivery is by HTTP webhooks across eleven functional areas (no public WebSocket — see
review.yml). - The reachable reference host is the QA/IO Docs environment (
updoxqa.com); the production base is provisioned per partner.
Confirmed from the IO Docs explorer and knowledge base: the Ping health checks, Address Book actions (AddressBookList incl. v1.1, AddressBookSearch, ContactCreate), the Faxing poll functions (FaxOemPop, PopPDF), and Video Chat VideoCallActions (SendInvite, retrieval). The remaining logical APIs below (Direct Messaging, Secure Conversation, Document Management, Patient Management, Patient Portal, Reminders, Forms, and the rest of Account Management) are modeled from Updox's documented functional areas and webhook catalog. The bundled OpenAPI (openapi/updox-openapi.yml) covers only the confirmed actions and is marked x-modeled: true.

List, search, and create practice-level contacts — AddressBookList (with an international-address v1.1), AddressBookSearch, and ContactCreate. Confirmed in the IO Docs explorer. Base URL: https://updoxqa.com/api/io.
Send and retrieve electronic faxes. FaxOemPop and PopPDF are multifunction poll endpoints that report whether inbound faxes are queued, return the fax image (PNG or PDF) in the JSON response, and mark it handled via lastRetrievedFaxId until endOfQueue. Faxing webhooks notify partners of fax events.
Telehealth video integration via VideoCallActions — SendInvite to invite a patient into an Updox Video Chat session, plus retrieval actions for call state. Paired with the Updox Video Chat web interface and video webhooks.
HISP Direct secure messaging between providers, with Direct Messaging webhooks. (Endpoints modeled from the documented functional area.)
Two-way secure patient conversations (secure text/SMS), with Secure Conversation Management webhooks. (Modeled.)
Create, retrieve, and route documents in the Updox inbox, with Document Management webhooks. (Modeled.)
Create and update patient records/demographics that anchor reminders, forms, portal, and conversations, with Patient Management webhooks. (Modeled.)
Provision and manage patient portal access and portal messaging, with Patient Portal webhooks. (Modeled.)
Schedule appointment reminders and broadcast messages across text, voice, and email, with Reminders webhooks. (Modeled.)
Send electronic intake/consent forms and receive completed submissions, with Forms webhooks. (Modeled.)
Administer accounts, users, and connectivity, including the tiered Ping health checks (confirmed) and Account Management webhooks. (Remaining endpoints modeled.)
Updox is subscription SaaS priced by practice size and capability mix; there is no public "buy now" list price. A pricing calculator and sales contact drive quotes. Reported tiers span a small/solo tier (~$49–$119 per provider/month), mid tiers with capped monthly allowances (faxes, telehealth sessions, reminders, broadcast messages), and a custom enterprise tier for larger practices, health systems, and EHR/pharmacy partners. API/integration access is provisioned to partners on top of a subscription rather than sold as a standalone metered API. See plans/ and finops/.
Does Updox expose a documented public WebSocket API? No. Updox's own public API is request/response HTTP POST (the IO API) and its event delivery is via HTTP webhooks — neither is a server-push WebSocket. No AsyncAPI document was authored. See review.yml.
