# Update a response format preset

PATCH https://api.respan.ai/api/response-format-presets/{id}/
Content-Type: application/json

When supplied, schema content is validated and preserved unchanged.

Reference: https://respan.ai/docs/apis/prompts/update-response-format-preset

## Authentication

- `Authorization` header (bearer token, required) — Use your Respan API key for Respan API authentication. Enter only the Respan API key value; clients send Authorization: Bearer \<RESPAN\_API\_KEY>. For /api/responses, provider credentials such as Perplexity, OpenAI, or Azure OpenAI go in Settings -> Providers or respan\_params.credential\_override in the request body, not in this authentication field.
- `Authorization` header (bearer token, required) — Use a dashboard JWT only for dashboard-authenticated endpoints. Respan API-key endpoints use the respanApiKey auth field instead.

## Request

### Path parameters

- `id` (string, required) — Response-format preset ID.

### Body (application/json)

This endpoint expects an object.

- `name` (string, optional)
- `response_format_content` (string, optional) — JSON text preserved verbatim. It must decode to an object with a non-empty `name` and an object-valued `schema`.
- `is_enforcing_response_format` (boolean, optional)

## Response

### 200

Preset updated.

- `id` (string, required)
- `name` (string, required)
- `response_format_content` (string, required) — JSON text preserved verbatim. It must decode to an object with a non-empty `name` and an object-valued `schema`.
- `is_enforcing_response_format` (boolean, required)
- `created_at` (datetime, required)
- `updated_at` (datetime, required)

## Errors

### 400 Bad Request Error

Invalid preset content.

- `map from string to any`

### 403 Forbidden Error

The API key is missing, invalid or expired.

- `detail` (string, required)

### 404 Not Found Error

Preset not found in the caller's project.

- `map from string to any`
