## Summary

Merge provides a unified API giving SaaS products access to 200+ HR, ATS, accounting, and CRM integrations via one normalized data model, compressing integration builds from months to days.

## Company Overview

Merge is a unified API platform that enables B2B SaaS companies to ship integrations with HR, applicant tracking, payroll, accounting, and CRM systems without building and maintaining each connector individually. Instead of negotiating with individual vendors, parsing inconsistent data schemas, and handling authentication edge cases for dozens of systems, product teams integrate once with Merge and gain access to a normalized data model that abstracts away provider-specific differences. This dramatically compresses the time-to-market for product integrations from months to days.

The platform covers over 200 third-party integrations across categories including HRIS (Workday, BambooHR, ADP), ATS (Greenhouse, Lever, iCIMS), accounting (QuickBooks, NetSuite, Xero), CRM (Salesforce, HubSpot), and file storage. Merge handles the ongoing maintenance burden — keeping up with provider API changes, managing OAuth flows, and surfacing data quality issues — so engineering teams can focus on core product work. A robust webhook system and comprehensive logging give teams visibility into integration health and data freshness.

Merge has become a standard choice for HR tech, fintech, and productivity SaaS companies that need to embed integrations as a product feature rather than a one-off engineering project. Its customers include Ramp, Drata, Gem, and AngelList. The company raised a $55M Series B and continues to expand its integration catalog and enterprise compliance features, including SOC 2 Type II certification, field-level access scoping, and audit logging to satisfy enterprise procurement requirements.

## Frequently Asked Questions

### How does Merge handle breaking changes from third-party APIs?
Merge monitors provider API changes and updates its connectors transparently, so customer integrations continue working without engineering intervention when upstream vendors change their APIs.

### What is Merge.dev and what categories of integrations does it support?
Merge is a unified API platform that enables B2B SaaS companies to integrate with HR, ATS (applicant tracking), payroll, accounting, CRM, and ticketing systems through a single normalized API. One Merge integration replaces dozens of individual vendor integrations.

### How does Merge normalize data across different providers?
Merge maps each provider API to a common data model — for example, all HRIS providers return employees using the same field names and data types, regardless of whether the underlying source is Workday, BambooHR, or Rippling. This normalization layer is the core value delivered by Merge.

### What is Merge Link and how does customer authorization work?
Merge Link is a frontend component that guides your customers through authenticating their third-party system (e.g., their Workday instance) using that vendor OAuth flow or API key configuration. Once authorized, Merge handles ongoing data synchronization using the customer credentials.

### How does Merge handle API rate limits from third-party providers?
Merge manages rate limiting, retry logic, and request scheduling for each connected provider automatically, so product teams do not need to build provider-specific rate limit handling or worry about sync jobs failing due to upstream throttling.

### Does Merge support real-time webhooks or only polling?
Merge supports webhooks for providers that offer them, and falls back to polling-based sync for providers without webhook support. Merge normalizes this difference so your application receives data change notifications in a consistent format regardless of the upstream mechanism.

### How is Merge priced?
Merge pricing is based on the number of linked accounts (customer integrations). A free tier supports development and testing. Production pricing scales with the number of customer accounts connected, with separate pricing tiers for different integration categories.

### Does Merge support custom field mapping for non-standard data?
Yes. Merge provides a Field Mapping feature that allows teams to map non-standard custom fields from specific provider instances to custom attributes in the Merge data model, handling the reality that enterprise customers often have custom fields in their HR or CRM systems.
