# Add a project (up to 100)

`POST /v1/showcases/{showcaseId}/projects`

## Request

- Base URL: `https://api.dropl.io` (the document declares no server; this is the origin it was published from)
- URL: `https://api.dropl.io/v1/showcases/{showcaseId}/projects`
- Auth: HTTP bearer

Requires the `showcases:write` scope (create and edit showcases, categories, and tags). Send `Idempotency-Key` to retry safely: a repeat with the same key and body within 24 hours returns the first response.
