Today, we’re pleased to announce that LuxSci just made it even easier to leverage its powerful high volume email API with the healthcare platforms you rely on most. Whether you’re connecting with an EHR system, Customer Data Platform (CDP), Revenue Capital Management (RCM) platform—or even your contact center or unified communications suite—the new LuxSci API authentication options unlock the flexibility you need to scale and move fast.

In healthcare, connected patient journeys anchored in secure, personalized communications are driving increased engagement and better outcomes for patients and companies—all at a lower cost. From sending secure high-volume transactional emails to targeted marketing and educational communications, your systems and platforms need to talk to each other without friction to achieve the best results. LuxSci’s new API updates make that possible, securely.

What’s New in This Update

• Support for OAuth 2.0, API Key, and Basic authentication methods.
• Published API YAML specs and SwaggerHub integration for instant testing.
• Enhanced multi-factor authentication (MFA) protection with one-time-use codes.

Overview of the LuxSci API

The LuxSci API is built with healthcare IT, security and developer teams in mind. It’s RESTful, secure, and designed for high volume email workflows.

Using industry standards like HTTPS, JSON, and TLS 1.2+, LuxSci’s API delivers fast and reliable integration and communication. Whether you’re sending appointment reminders, test results, preventative care communications, explanation of benefits (EoBs), or new product offers, your messages go out quickly and securely, with best-in-class email deliverability rates of 98% or more.

Designed for Compliance and Performance

LuxSci is HIPAA-compliant and HITRUST Certified, ensuring your healthcare communications stay within the bounds of regulatory compliance, keeping patient and company data secure—even as your email sending volume scales into the millions.

Authentication Gets a Major Upgrade

With the latest API release, LuxSci now supports three industry-standard authentication methods—alongside its proprietary LuxSci Secure option.

Let’s break them down:

1. OAuth 2.0 – The modern standard. Secure, flexible, and ideal for enterprise-scale integrations.
2. API Key – Simple and efficient. Ideal for server-to-server use when convenience matters most.
3. Basic Authentication – Straightforward and widely supported. Great for internal systems and quick testing.

Still Available and Highly Recommended: LuxSci Secure Authentication

For those who want the tightest possible control over API sessions—including HMAC signatures and session revocation—LuxSci Secure authentication remains the best option for customers.

Now, let’s take a closer look at how each of the new authentication methods work:

OAuth 2.0: A Standards-Based Approach

OAuth 2.0 gives you a robust framework to handle both account-level and user-level integrations.

Account-Level Authentication (Client Credentials Flow)

Perfect for system-level access—including EHR, CDP or RCM platform integrations where user context isn’t needed.

User-Level Authentication (Resource Owner Password Credentials Flow)

This method allows API access on behalf of individual users—great for patient portals or provider tools.

Security, Flexibility, and Simplicity Combined

Tokens expire after a default of 15 minutes, ensuring sessions aren’t left open indefinitely. Bonus: No message body signing is required, making integration quick and painless.

API Key: Simple and Straightforward

API Key authentication is as easy as including your credentials in a custom header. No session to manage, no extra handshake steps.

How It Works:

You send the HTTP header

X-API-Key: client_id:client_secret

With each request. That’s it.

Ideal Use Cases

• Server-to-server automation
• Internal dashboards
• Data exports from analytics platforms

Basic Authentication: Familiar and Easy

Basic Auth is a time-tested option. Just Base64 encode your API credentials, include them in an HTTP header, and go.

While not as bulletproof as OAuth or LuxSci Secure, API Key and Basic Auth work fine for less sensitive data or development environments.

Easy Access to YAML Specs and SwaggerHub for API Testing

LuxSci has also published detailed YAML API specifications, making it easier for developers and IT teams to access testing interfaces.

You can find more information on our LuxSci API page.

Improved MFA and Easier Access to Testing Tools

As part of today’s announcement, LuxSci also rolled out new, smarter Multi-Factor Authentication (MFA) for enhanced web interface login protection.

LuxSci now ensures that each MFA code can be used only once. So, even if a hacker captures your password and MFA code, they are useless for conducting new login sessions. This update helps protect against automated phishing, spoofing, and fake login pages.

At LuxSci, we’re committed to making secure communication easier and more efficient for healthcare organizations. Today, we’re excited to introduce Unified Login—a new feature that simplifies identity management and streamlines access to multiple LuxSci accounts, helping users and administrators save time and improve workflows, without sacrificing security.

If your organization manages multiple LuxSci accounts—or if you’re new to LuxSci and require multiple secure email accounts and domains—switching between them just became faster, easier, and more efficient. With Unified Login, users can seamlessly move between linked accounts without the hassle of repeated logins, ensuring uninterrupted productivity while maintaining strict security and compliance standards.

Why Unified Login?

Healthcare professionals, IT administrators & security, marketing teams, and compliance officers often need to manage multiple secure email accounts across different departments, domains, or business units. Traditionally, switching between accounts required a separate login, disrupting workflows and wasting time by requiring multiple logins and passwords.

With LuxSci’s new Unified Login feature, administrators can link user identities across accounts and domains, enabling one-click access without repeated authentication. This means:

• More Efficiency – No more logging in and out multiple times a day. Switch identities instantly and move between accounts uninterrupted.
• Better User Experience – Access the accounts and resources you need in seconds, with a seamless transition between roles and domains.
• Strong Security & Compliance – Every identity switch is logged for full transparency. Actions performed under a switched identity also track who switched into the identity, ensuring security and regulatory compliance are maintained.

Real-World Use Cases

Here’s how Unified Login can benefit different healthcare functions and use cases:

Compliance Officers & IT Security

A compliance officer or IT security director conducting an audit across multiple business units can quickly switch between accounts to check email logs, security settings, and compliance reports—saving time and reducing administrative burdens.

Healthcare Marketing Teams

A healthcare marketing professional or a digital communications manager sending out segmented campaigns across different services, products, or brands can quickly and easily navigate between campaigns and results for each account or domain.

IT Administrators Managing Multiple Accounts

A hospital or health plan IT administrator overseeing multiple accounts for different departments (e.g., patient services, billing, and compliance) can now switch between accounts instantly—without re-entering credentials each time. This speeds up troubleshooting, reporting, and user management, making workflows significantly more efficient.

Physicians & Providers with Multiple Roles

A doctor working across multiple clinics or locations with separate email accounts can easily transition between them without needing to log out and back in. Whether reviewing patient communications or sending secure messages, Unified Login ensures a seamless and secure experience.

How It Works

Unified Login provides administrator-managed identity linking, ensuring organizations retain full control over who can switch between accounts. The feature supports:

• Unique Access Separation – Users maintain distinct identities, having quick access when needed.
• Shared & Delegated Access – Teams working across multiple accounts can transition seamlessly.
• Administrative Access – IT and compliance teams can manage multiple accounts efficiently while maintaining strict security protocols.

The main features of Unified Login include:

• Administrators can link individual users to other users in the same or a different account.
• Users can switch identities with one click without the need to re-authenticate.
• Each identity switch starts a new session, giving the user the same access and permissions as the target identity.
• Access and audit logs reference the original user, preserving accountability.

Once configured, users will see a “Switch Identity To” section in their account menu. Clicking on a linked identity seamlessly switches to a new session with the appropriate permissions, ensuring security while keeping workflows uninterrupted. If two or more identities are available, a “View All Identities” option appears.

Designed for Secure Healthcare, Built for Convenience

As a leader in HIPAA-compliant secure communications, LuxSci understands the challenges of balancing efficiency with security. Unified Login is ideal for healthcare organizations that need:

• Secure, streamlined workflows for managing multiple email accounts for multiple business units, departments, or locations.
• Faster access to multiple accounts for authorized personnel without compromising compliance.
• Reduced password fatigue for users managing multiple roles or accounts.
