# Create a form

`POST /v1/forms`

## Request

- Base URL: `https://postbag.dev`
- URL: `https://postbag.dev/v1/forms`
- Auth: HTTP bearer

Pass `from_template` (a stream id) to attach the new form to that stream with a schema copied 1:1 from it, so the mapping is trivially complete. Pass `if_exists: "return"` to make this call safe to re-run.

## Request body

- object
  - `name` string
  - `slug` string
  - `project` string
  - `tags` string[]
  - `status` 'active' | 'paused'
  - `schema_mode` 'observe' | 'enforce' | 'managed'
  - `settings` object
    - `allowed_origins` string[]
    - `redirect_url` string, uri, nullable
    - `honeypot_field` string
    - `turnstile` object
      - `secret` string
      - `enabled` boolean
    - `rate_limit` object
      - `per_minute` integer
      - `burst` integer
    - `reply_to_field` string, nullable
  - `schema` object
    - `json_schema` object, required: JSON Schema draft 2020-12 describing the submission data. `required` drives drift detection and mapping completeness.
    - `ui` object: Per-field rendering hints keyed by field name (label, placeholder, widget, options, order) — used to render embed snippets.
    - `changelog` string: A short human note on what changed in this version, shown in the version history.
  - `from_template` string
  - `if_exists` 'error' | 'return'
