OpenAPI Specification


Tyk has always had a proprietary specification for defining APIs. From Tyk v4.1 Tyk now also supports defining APIs using the Open API Specification (OAS) which can offer significant time and complexity savings. This is an early access capability.

As we extend our OAS support, we would very much like your feedback on how we can extend and update to best meet your needs: We have created an OAS Category in our Community Forum if you do have any feedback or questions.

This capability is available in both the open source and paid versions of Tyk. See our High Level Concepts for more details. We also have a glossary of terms, or, if you can’t wait to get started, head on over to Using OAS API Definitions for tutorials.
