Test Before You Build
Request a test site to validate your integration in a sandbox environment before turning it on in production.
How It Works
The path from “we want to integrate” to a working production connection is documented end to end on the APS developer portal.
-
Submit a request through the APS developer portal. Once approved, you’ll get test site access and the credentials your team needs to start building.
-
Use the API Reference, authentication guide, and developer docs to build against your test environment. Validate the integration end-to-end before going live.
-
Authenticate to the production API using the token-based flow documented in the developer portal. Pull or push data as your integration requires.
-
The developer portal includes an API Change Log so your team can stay ahead of updates and adjust integrations proactively, rather than reactively.

Frequently Asked Questions
What can I do with the APS Developer API?
The APS Developer API gives your engineering team programmatic access to the data inside APS — including employee records, company structure, departments, attendance, and pay data. It’s designed for teams that want to build private integrations between APS and their own internal applications, and for vendors and partners building APS integrations into their own products. Full documentation, authentication guides, and an API change log are available at developer.apspayroll.com.
What's the difference between the API and the Enterprise Integration Platform (EIP)?
Both are integration tools, but they serve different purposes. The APS API is a set of REST endpoints your team can call to read or update data inside APS in real time — useful for syncing data on demand, building dashboards, or triggering workflows. The Enterprise Integration Platform is a structured file-based integration designed specifically for transmitting employee demographic and record data from an external HR or workforce system into APS. EIP files are sent in a defined XML format over a secure SFTP connection and pass through multiple validation layers before being applied to your data.
Who can use the APS API, and how is it priced?
The API is built for two audiences. First, APS customers with their own software engineering resources who want to build private integrations for use within their organization. Second, vendors and established APS partners who want to build APS integrations into their own products. Access is granted through a request-and-approval process. Current pricing details are available on the developer portal FAQ.
