# General Translation Platform: Crear o actualizar instrucciones personalizadas
URL: https://generaltranslation.com/es/docs/platform/openapi/reference/context-management/upsert-custom-prompts.mdx
Docs index: https://generaltranslation.com/llms.txt
Description: Crea o actualiza de 1 a 100 instrucciones ({ customPrompts: [...] }), cada una identificada por nombre y configuración regional, en un único lote atómico. Un campo ausente conserva su valor almacenado. null borra un campo que admite valores nulos o elimina una entrada de un mapa; los demás campos rechazan null. En lotes e importaciones, los elementos se emparejan con los almacenados mediante su 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. Si un mismo nombre y configuración regional se repiten dentro de un lote, se rechaza el lote completo (400). Requiere org:context:write. Referencia de la API para Crear o actualizar instrucciones personalizadas.

## Endpoint

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

**Operation ID:** `upsertContextCustomPrompts`

**Tags:** `Context Management`

**Summary:** Upsert custom prompts

Creates or updates 1–100 prompts (`{ customPrompts: [...] }`), each matched by name and locale, in one atomic batch. 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. Repeating a name and locale within one batch rejects the whole batch (400). Requires `org:context:write`.

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