Connecting EMS Software: A Guide to Integrations and APIs

Start with the task you want to simplify

Choose a specific problem. Do not connect systems simply because an integration exists. Examples include transferring approved time information into payroll, keeping employee information consistent, bringing training completion information into a recordkeeping process, or making operational information available for reporting.

Describe the desired result in one sentence. For example: “We need to transfer reviewed employee hours into our payroll platform without retyping them.”

Understand the connection options

Providers may use different methods to exchange information. A built-in connection is an existing link designed for particular systems or workflows. File export and import means someone downloads information from one system and uploads it into another. An API connection lets software exchange supported information through a defined interface, and a custom connection is one someone develops or configures for specific requirements.

An API does not automatically mean every record or function is available. Ask what the particular connection supports.

Define the information you exchange

List the fields the receiving system needs. Confirm which records you include, how each system identifies employees or items and which fields it requires. Check whether codes and formats match, which system owns the authoritative record and whether information moves in one direction or both.

Matching names alone may be unreliable. Confirm how each system identifies the correct employee or record.

Clarify timing and responsibilities

Ask whether information moves immediately, on a schedule or through a manual action. Establish who starts or monitors the transfer, who investigates failures and how you handle corrections. Decide what happens when information changes after transfer, and who maintains the connection when either system changes.

Do not assume a connection runs continuously or updates previously transferred information.

Review access and data handling

Involve the appropriate technical and administrative contacts. Confirm what information the connection can access, how you authorize access and how you can remove it. Request relevant documentation, and follow your organization's requirements for handling sensitive information.

Test realistic examples

Before you rely on the connection, test representative records. Check for missing fields, incorrect matches, rejected records and duplicates, and compare the results in the receiving system with the original information.

Agree on how to correct a failed transfer before you repeat it.

Confirm scope and costs

Ask each provider to document the included functions, setup responsibilities and any subscription or connection charges. Ask about custom development or export costs, third-party charges and ongoing support arrangements.

Evaluate a connection on the workflow it supports. Two product names appearing together tell you very little.

Your EMS software connection checklist

Nine questions to answer first:

• Define the task you want to simplify.
• Confirm the available connection method.
• Identify required records and fields.
• Establish the authoritative source.
• Verify transfer direction and timing.
• Assign monitoring and correction responsibilities.
• Review access and data handling.
• Test representative records.
• Confirm scope, support, and costs.
