Merge

Merge is a unified API platform that enables B2B SaaS companies to add integrations with HR, recruiting, payroll, CRM, ticketing, accounting, and file storage systems to their products quickly. Instead of building and maintaining individual point integrations with dozens of third-party tools, product teams integrate Merge once and gain access to integrations with hundreds of third-party platforms through a single, normalized API.

The integration categories that Merge covers include Human Resources Information Systems (HRIS) including Workday, ADP, BambooHR, and Rippling, Applicant Tracking Systems (ATS) including Greenhouse, Lever, Workable, and iCIMS, Customer Relationship Management (CRM) including Salesforce and HubSpot, Ticketing systems including JIRA, ServiceNow, and Zendesk, Accounting platforms including QuickBooks and Xero, and File Storage services including Google Drive, Dropbox, and Box.

The normalized data model is central to Merge's value. Instead of returning data in each provider's idiosyncratic format, Merge normalizes all data from all providers into a single, consistent schema for each category. A developer integrating the Merge HRIS API receives employee, department, and employment data in the same format regardless of whether the customer uses Workday, BambooHR, or another HRIS. This normalization dramatically reduces the per-provider development effort.

The Merge Link component provides the pre-built authentication flow that customers use to connect their third-party accounts. It handles OAuth flows, API key configuration, and connection verification for each supported platform, returning a linked account token that the integrating application uses to access the customer's data through the Merge API.

Passthrough requests in Merge allow making arbitrary API calls to the connected third-party platforms when the normalized model does not include a needed data element, providing an escape hatch for edge cases without requiring platform-specific SDK integrations.

Webhook support in Merge delivers real-time notifications when data changes in connected third-party platforms, enabling integrating applications to keep their data synchronized with source systems as changes occur rather than relying on polling.
