To help developers quickly create their client-side libraries in any language of their choice, we provide an OpenAPI Specification (OAS) version 3 file.
This is the same OAS that we consume ourselves to generate our server-side libraries and we are happy to share as the most accurate and complete representation of the Yapily API.
The latest version of the API definition is available here.
You can find all versions in our GitHub repo yapily-openapi. This includes a readme explaining how to autogenerate libraries in the languages that are most popular with our customers.
