# Generate with P-Image Ideogram asynchronously

`POST /v1/async/text-to-image/p-image-ideogram`

Accepts a P-Image Ideogram generation request for asynchronous processing
and returns immediately with a generation_id. Poll
`GET /v1/generations/{generation_id}` to retrieve the result. If a
`webhook_url` is supplied, the generated images are additionally POSTed
to it once ready, in a payload that mirrors the synchronous response with
an added generation_id for correlation.

See [Webhooks](/ideogram-api/webhooks) for the delivery payload and how to verify webhook signatures.

## Query parameters

- `webhook_url` string, uri — HTTPS URL that Ideogram delivers the generated result to. Ideogram sends a JSON POST to this URL once all images for the request have finished generating. The body mirrors the synchronous generate response: `request_id`, `created`, and a `data` array containing every generated image (`url`, `prompt`, `resolution`, `seed`, `is_image_safe`). Each delivery is signed with Ed25519 and verifiable against the public keys at `https://api.ideogram.ai/v1/.well-known/jwks.json`. Must be HTTPS; private and loopback hosts and the cloud metadata service are rejected.

## Request body

- GenerateImageRequestPImageIdeogram — Request body for P-Image Ideogram. The model's quality and resolution tier are supplied as request parameters. The server selects the matching P-Image model variant; custom registry models cannot be selected.
  - `prompt` string, required — The prompt for image generation. Accepts either natural language or a structured Ideogram 4.0 JSON prompt; the server detects which was supplied.
  - `prompt_upsampling` 'AUTO' | 'ON' | 'OFF' — Determine if MagicPrompt should be used in generating the request or not.
  - `seed` integer, nullable — Random seed for reproducibility.
  - `magic_prompt_system_prompt_config_id` string — A base64url-encoded magic prompt system prompt config ID to use for this request.
  - `quality` 'VERY_LOW' | 'LOW' | 'MEDIUM' | 'HIGH' — The generation quality level. Higher levels may use more inference steps or additional prompt processing.
  - `resolution` '1K' | '2K' — The output-size tier for P-Image Ideogram.
  - `aspect_ratio` '1x3' | '3x1' | '1x2' | '2x1' | '9x16' | '16x9' | '10x16' | '16x10' | '2x3' | '3x2' | '3x4' | '4x3' | '4x5' | '5x4' | '1x1' — The aspect ratio to use for image generation, which determines the image's resolution. Cannot be used in conjunction with resolution. Defaults to 1x1.
  - `custom_width` integer, nullable — Optional. An exact output width in pixels, used together with `custom_height` for output sizes outside the preset tiers. Must be a positive multiple of 16 between 16 and 4096, and `custom_width` × `custom_height` must not exceed 4,194,304 pixels (2048×2048). Cannot be combined with `resolution` or `aspect_ratio`; the request is billed at the resolution tier matching its total pixel count.
  - `custom_height` integer, nullable — Optional. An exact output height in pixels, used together with `custom_width`. See `custom_width` for the accepted range and billing behavior.
  - `enable_copyright_detection` boolean, nullable — Optional. Opt this request into post-generation copyright detection.

## Response `200`

Request accepted for asynchronous delivery.

- AsyncImageGenerationResponseV4 — Acknowledgement returned by the async (webhook) generation endpoints. The request is accepted for asynchronous processing and the generated images are POSTed to the supplied `webhook_url` once ready; this body carries only the generation_id so the caller can correlate the eventual webhook delivery.
  - `generation_id` string, required — URL-safe base64 ID of the accepted generation. Matches the `generation_id` field delivered in the webhook payload, and the `generation_id` accepted by the generation polling endpoint.

## Other responses

- `400` — Invalid input provided.
- `401` — Not authorized.
- `422` — Prompt failed the safety check.
- `429` — Too many requests.
