You can export your API into any of the supported API specification formats in APIMatic. All popular formats like OpenAPI, RAML and API Blueprint are supported.
On the APIMatic Dashboard, click on the three dots on the API entity that you want to export.
Select Export API from the options.
Select the API version you want to export, choose the Export Format from the dropdown and click Export. By default, the API is exported without any specification extensions (e.g. OpenAPI/Swagger vendor extensions). However, you can export your API along with extensions by enabling the Include Extensions flag. The API definition will be exported into the desired format.
