URL: https://generaltranslation.com/es/docs/platform/openapi/reference/context-management/update-custom-prompt.mdx
Docs index: https://generaltranslation.com/llms.txt
Description: Actualiza un prompt por ID. Si un campo no se incluye, conserva su valor almacenado. null borra un campo anulable o elimina una entrada de un mapa; los demás campos rechazan null. En lotes e importaciones, los elementos se emparejan con los almacenados por clave natural, los elementos almacenados que no figuran en el lote no se modifican y no se elimina nada más. Una celda CSV vacía se considera ausente. Devuelve 409 si otro prompt ya tiene el nombre y la configuración regional resultantes. Requiere org:context:write. Referencia de la API para Actualizar un prompt personalizado.

## Endpoint

`PATCH https://api.gtx.dev/v2/context-groups/{groupId}/custom-prompts/{customPromptId}`

**Operation ID:** `updateContextCustomPrompt`

**Tags:** `Context Management`

**Summary:** Update a custom prompt

Updates a prompt by ID. An absent field keeps its stored value. `null` clears a nullable field or removes a map entry; other fields reject `null`. In batches and imports, items match stored items by natural key, stored items absent from the batch are untouched, and nothing else is deleted. A blank CSV cell counts as absent. Returns 409 if another prompt already has the resulting name and locale. Requires `org:context:write`.

Authentication: required. Send an API key in the `Authorization: Bearer <key>` header when authenticating.

### Request body (required)
