Versioning and stability

|View as Markdown|Open in Claude|

We strongly aim for backward compatibility for the documented endpoints. If backwards-incompatible changes are made, we will aim to release a new version.

  • URLs’ entry point is https://api.prolific.com/api/.

  • URLs are versioned https://api.prolific.com/api/v1/endpoints/

Our web application uses the same API and applies the same high-security standards.
