Advertisement Resizer

Resizes an advertisement image to the exact target size. Supply prompt to provide specific instructions for how the advertisement should look after resizing.

The request is processed asynchronously and immediately returns a generation_id. Poll GET /v1/generations/{generation_id} until status is completed or failed. When completed, data contains the final resized image(s). If a webhook_url is supplied, the completed result is also POSTed to that URL.

Supply the advertisement image as either an AssetIdentifier reference (image_asset_identifier) or the raw image bytes directly (image, multipart requests only). Provide exactly one of the two; supplying both, or neither, is rejected with a 400.

The required resolution (WIDTHxHEIGHT) sets the exact output dimensions.

The model is fixed by the route, so no model field is accepted.

Query parameters

webhook_urlstring 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.

Target ad resolution, formatted as WIDTHxHEIGHT. Must be one of the supported ad resolutions listed above; any other value is rejected with a 400. Each returned image has exactly these pixel dimensions.

promptstring

Optional edit instruction to apply while reframing, for example "remove the logo" or "put the price bottom-right".

quality'LOW' | 'MEDIUM' | 'HIGH'
num_imagesinteger

The number of reframed variations to generate.

store_assetsboolean

Reserved for a future release: accepted for forward compatibility but not yet applied. Resulting assets are not stored to your account regardless of this value.

Example request

{
  "image_asset_identifier": {
    "asset_type": "RESPONSE",
    "asset_id": "7uS_VESkRI6O3-sVgHQp_A"
  }
}

Response

Request accepted for asynchronous processing.

generation_idstring 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.

Example response

{
  "generation_id": "generation_id"
}
