Not all payroll integrations are created equal. Many vendors still rely on outdated and risky methods like screen scraping or stored client credentials to access payroll data. These approaches create major security vulnerabilities, unreliable data flows, and compliance concerns - especially for benefits platforms, recordkeepers, and TPAs serving enterprise employers.
The alternative is API-only payroll integration: a safe, scalable, and compliant approach that eliminates login-based data collection entirely.
This is the foundation Payroll Integrations was built on - and the reason enterprise organizations rely on us for trusted payroll connectivity.
Screen scraping works by logging into a payroll system as the employer, mimicking human clicks and copying whatever appears on the screen. While this may appear to “get the job done,” it introduces significant dangers:
Screen-scraping typically requires storing employer usernames and passwords in a vendor’s system - a major liability:
This is fundamentally incompatible with modern security frameworks like SOC 2 or NIST.
Payroll interfaces change constantly. Even small updates break scrapers:
When this happens, your platform loses visibility into payroll activity, and employers are left frustrated.
Scraping requires loading multiple screens, waiting for pages to render, and parsing inconsistent data structures. This introduces:
Using employer logins creates complications in:
Any integration that requires employers to provide their payroll username and password should be treated as a red flag.
For benefit platforms trying to scale reliably, this creates a fragile foundation.
API-only integration means direct, authenticated, system-to-system communication - without logins, scraping, or brittle workarounds.
With APIs:
This is the method Payroll Integrations uses for every payroll relationship - and the reason our customers trust us with mission-critical data flows.
Payroll Integrations uses exclusively API-only connections across our 200+ payroll integrations. We never store employer credentials or log in on behalf of your customers.
Here’s how we keep your data safe and reliable:
Independent, annual security audits verify our controls, processes, and compliance posture.
We do not - and will never - collect or store employer usernames or passwords.
APIs are stable, documented, and built to scale. We maintain 99.9% uptime across our connections.
Census data, deductions, and contributions flow instantly - no delays or broken scrapers.
Recordkeepers, TPAs, and benefits platforms routinely reduce payroll-related support inquiries by up to 50% or more.
This is what modern payroll integration should look like.

Use these questions during vendor evaluation to surface security risks early.
Enterprise buyers increasingly reject scraping-based vendors for these reasons. If the vendor cannot answer “yes” to the security questions - or avoids answering them - proceed with caution.
Payroll Integrations is built to support secure, scalable, enterprise-grade payroll connectivity. Our API-only approach ensures:
No scraping. No stored credentials. No fragile connections.
Just secure, reliable payroll data - delivered automatically.

A payroll API is a direct, system-to-system connection between two software platforms using authenticated, documented endpoints. Screen scraping is an indirect method that logs into a payroll provider's website as a human user and copies data from the visible interface. APIs are stable, fast, and secure. Screen scraping is fragile, slow, and depends on storing employer credentials.
No. Screen scraping requires storing employer usernames and passwords, which creates significant security and compliance risk. Stored credentials are vulnerable to data breaches, leave incomplete audit trails, and fail SOC 2 and NIST control requirements. Most enterprise buyers reject screen-scraping vendors during security review.
API-only integration uses token-based authentication (OAuth or API keys) to connect two systems directly. The payroll provider issues a credential to the integration platform that allows specific data exchanges — without ever sharing employer login passwords. Data flows in structured, documented formats in real time.
SOC 2 Type II is an independent audit standard that verifies a vendor's security controls operate effectively over time. For payroll integrations, SOC 2 Type II certification confirms the vendor handles sensitive employee and compensation data according to enterprise security requirements. Enterprise buyers, recordkeepers, and TPAs increasingly require SOC 2 Type II certification before approving a vendor.
With screen scraping, even minor HTML or interface changes can break the integration entirely, leaving customers without data flow until the scraper is rebuilt. With API integration, changes are managed through documented version updates and rarely break existing connections. This is why API-only platforms maintain higher uptime.
Stored credentials create a single-point-of-failure for breach exposure: one successful attack can expose every employer's payroll account. They also create vendor lock-in (switching vendors means resetting every employer's payroll login), incomplete audit trails (logins look like human activity), and ongoing IT risk during vendor reviews.
No. Payroll Integrations is exclusively API-only across all 200+ payroll integrations. We never collect or store employer credentials and never log in on behalf of customers.
If your platform is growing or supporting enterprise clients, moving to an API-only integration model isn’t optional - it’s essential. Payroll Integrations gives you the safest, fastest, and most audit-ready method for connecting payroll data.
