Building an Engine to Streamline Third-Party Integrations

Summary

WHOOP had a backlog of third-party integrations. The Gnar built an integration engine in React and Next.js, freeing their engineers to scale the core product.

Problem

Whoop’s explosive growth led to capacity constraints in their engineering team resulting in new third-party integrations getting stuck in the backlog.

Solution

Whoop partnered with The Gnar to facilitate new customer integrations and supporting documentation. The Gnar started by building a sample testing application and associated documentation to enable Whoop integration partners to easily test their Whoop API integrations.

The Gnar served as the "first line of defense" for all third-party companies that wanted to integrate with the Whoop API, which included:

  • onboarding calls with developers
  • implementation of best practices to the API
  • self-service documentation creation
  • robust reporting

Results

As a strategic extension of their engineering team, we enabled the core members to focus on building the product during a time of hypergrowth, while providing the peace of mind that new partners would have a frictionless onboarding experience.
