Before and After Guide: API for Split Admins

This guide provides a Postman collection with API examples for the five Split Admin API endpoints that will be replaced by Harness API endpoints during your Split-to-Harness migration.

Each folder includes an overview section with detailed guidance tailored for both experienced Split administrators and those new to Split and Harness FME—to support a smooth and well-prepared transition for you.

FAQs

Q: Will this collection be published at https://github.com/splitio/public-api-postman as well?

A: Yes.  It's there, as are diff's of changes we make to this guide.

Q: Will the existing Postman collection for Split Public API endpoints on GitHub be maintained going forward?

A: Yes. For clarity and consistency the variables in that collection will be updated soon to use the same variables as this collection. Later, we will update it to include the “after” endpoints seen here.
