Subsets of the OPEN API specifications

[Ward Schwillens_ Schwillie]

Hi,

I am creating PowerApps custom connectors to interact with Jira cloud through Rest API. Now There's one big #ss Open API specification 😁 at https://developer.atlassian.com/cloud/jira/platform/swagger-v3.v3.json. But that's a bit too much.

Would there exist some subset OpenAPI Specification?

E.g.

• Create/Update/Get/Delete issues API Actions set
• Create/Update/Get/Delete projects API Actions set
• Create/Update/Get/Delete User Group API Actions set
• Get, Insert, Delete, List Paginated User Group Members set
• ...

Or is there a very good open API editor that can read the full OpenAPI specification and generate subsets? 

Convert to Swagger function could also be included.

Any suggestions... thanks!
