What is Merge?
Merge builds unified APIs for common SaaS integration categories - HRIS, applicant tracking, CRM, accounting, ticketing and file storage - so a product team writes one integration per category and gets many third-party providers behind it, plus a hosted authentication flow (Merge Link) for end customers.

Key capabilities
- Unified APIs: One schema per category (HRIS, ATS, CRM, accounting, ticketing, file storage) across many providers.
- Merge Link: Hosted OAuth/credential flow for end customers to connect their tools.
- Webhooks and sync: Ongoing data sync with webhook notifications for changes.
Check that the specific third-party providers your customers actually use are supported in each category, and test field-mapping coverage for the data your product needs, since unified schemas can't expose every provider-specific field.
Shortlist Merge when your product needs to support many third-party integrations within one category (e.g. many HRIS or ATS systems) and you want to avoid building and maintaining each connector separately.
A unified API only helps if it covers your customers' real tool mix; verify provider coverage and field completeness for your top few required integrations before building against it.
