# Duplicate a project (or save it as a template)

`POST /projects/{id}/duplicate`

## Request

- Base URL: `https://tasg.app/api/v1`
- URL: `https://tasg.app/api/v1/projects/{id}/duplicate`
- Auth: HTTP bearer

Copies the project's structure: sections, tasks, subtasks, priorities, categories and tags. Progress, assignees, dates, comments and attachments are reset, and members are not carried over; the caller becomes the copy's owner. With `as_template: true` the copy gets status `template`, which is what the new-project template picker lists; create a project FROM a template by duplicating the template without that flag. Any project member; guests cannot duplicate.

## Path parameters

- `id` string, uuid, required

## Request body

- object
  - `name` string: Defaults to the source name plus " (copy)" or " (template)".
  - `as_template` boolean: Create the copy with status `template`.
  - `include_tasks` boolean: Default true. False copies only the project and its sections.

## Other responses

- `400`: Validation failed: the body or query did not match the schema, or a business rule was violated. `error` says which.
- `401`: Missing, invalid, expired or revoked credentials.
- `403`: Authenticated, but not allowed: not a member, insufficient project role or the API token lacks the required scope.
- `404`: Not found, or not visible to the caller (tenancy is enforced: foreign resources look identical to missing ones).
- `429`: Rate limited. Back off and retry after the window in the `RateLimit-*` headers.
