# Copy one collection document's original file into a connected project's store

`POST /api/v0/desk/projects/{project_id}/knowledge-base-file`

## Request

- Base URL: `https://api.outerport.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.outerport.com/api/v0/desk/projects/{project_id}/knowledge-base-file`
- Auth: HTTP bearer
- TypeScript: <https://skmtc.dev/outerport/apis/outerport-api/docs/api/v0/desk/projects/:project_id/knowledge-base-file/post.ts> (a function with typed inputs; its response is checked against the schema)

Stores the document's original file in the project owner's store and answers the entry to commit at ``path``. Nothing is committed: ``/knowledge-base/commit`` commits every file copied, in one write. The document must belong to the project's collection, and, while the project is shared, to the organization it is shared with.
