Endpoints, fields, and behavior may still change, so avoid depending on it in production. Generates fresh creative for one asset group, for when its existing creative has stopped performing. Use it when [List Google Ads asset performance](/api-reference/list-google-ads-asset-performance) shows an asset group rated `POOR` or `LOW`. That endpoint tells you creative has gone stale; this is what replaces it. Nothing reaches Google Ads here. The response is the same shape as [Generate Google Ads assets](/api-reference/generate-google-ads-assets), and the new creative comes back as previews you accept one at a time with [Accept a generated Google Ads asset](/api-reference/accept-a-generated-google-ads-asset). Nothing on the asset group is replaced or removed for you, so accepting adds to what is already there rather than swapping it. Pass the asset group's Google Ads ID, which is numeric. Anything else is rejected with a 422 without a call to Google. The rate limits, the two 200 shapes, and the retry accounting are the same as [Generate Google Ads assets](/api-reference/generate-google-ads-assets), because this runs the same generation underneath. When Google refuses the page you pointed at, Base44 retries once on the app's own published URL, and that retry costs the same again. Pace requests against the doubled figure, not the single one, or a refusal-heavy app hits a 429 part-way through its own recovery. Generating creative does not spend credits and is not billed. It is capped by rate limits instead, so a burst gets a 429 rather than a bill. This endpoint accepts a personal API key. Workspace API keys are not authorized for it and are rejected with a 403. The response includes fields beyond the ones documented here. Don't rely on undocumented response fields, as they can change at any time. Send only the fields documented here. Other request fields are not supported and their behavior can change. ## OpenAPI ````yaml /developers/references/app-management/app-management-openapi.json post /api/apps/{app_id}/google-ads/asset-groups/{asset_group_id}/regenerate-assets openapi: 3.1.0 info: title: Base44 App Management API version: 1.0.0 servers: - url: https://app.base44.com security: - ApiKeyAuth: [] paths: /api/apps/{app_id}/google-ads/asset-groups/{asset_group_id}/regenerate-assets: post: summary: Regenerate Google Ads asset group creative description: >- This API is in beta.

One of `PERFORMANCE_MAX`, `DEMAND_GEN`, `SEARCH` or `DISPLAY`. Asset groups belong to Performance Max campaigns, so the default is the value you almost always want. default: PERFORMANCE_MAX example: PERFORMANCE_MAX final_url: type: string description: >- Page the new pictures should be based on. Send this or `freeform_prompt`, not both, or omit both to ground the creative in the app's own home page. example: https://example.com/spring freeform_prompt: type: string description: >- What the new creative should show, in your own words, up to 1500 characters. Send this or `final_url`, not both. example: Brighter lifestyle shots with the product in use example: channel_type: PERFORMANCE_MAX freeform_prompt: Brighter lifestyle shots with the product in use responses: '200': description: The replacement creative that was generated. content: application/json: schema: $ref: '#/components/schemas/GenerateAssetsResult' '400': description: >- Google Ads rejected the generation request, for example a landing page it could not read. The response message carries Google's reason. '401': description: Missing or invalid credentials. '403': description: >- You don't have access to this app, the app does not exist, or you used a workspace API key. A missing app and an app you cannot reach are deliberately the same answer. '404': description: >- No asset group with this ID exists on the app's Google Ads account, or the campaign it belongs to is not one Base44 manages for this app. '409': description: >- The app's Google Ads account is not ready to generate assets yet, or the request to Google Ads timed out after being sent. Nothing was attached to a campaign either way, so retrying is safe. '422': description: >- The asset group ID is not numeric, or you sent both `final_url` and `freeform_prompt`, or `freeform_prompt` is longer than 1500 characters. '429': description: >- The app has used up one of the creative rate limits, either 20 copy requests a minute or 10 picture requests a minute. Retry later. components: schemas: GenerateAssetsResult: properties: session_id: type: string title: Session Id description: >- ID of this generation. Pass it as `session_id` to [List Google Ads generated assets](/api-reference/list-google-ads-generated-assets) to poll for the images that are still coming. example: 9c1d2e3f-4a5b-6c7d-8e9f-0a1b2c3d4e5f text: items: $ref: '#/components/schemas/GeneratedAssetSummary' type: array title: Text description: >- The copy that was generated. Empty when the text engine produced nothing and when a generation for this app was already running. example: [] images: items: $ref: '#/components/schemas/GeneratedAssetSummary' type: array title: Images description: >- The pictures that finished in time to be returned inline. The rest are counted in `background_image_count`. example: [] background_image_count: anyOf: - type: integer - type: 'null' title: Background Image Count description: >- How many more pictures are still being generated for this session. The response comes back as soon as the copy is done, so poll [List Google Ads generated assets](/api-reference/list-google-ads-generated-assets) with `session_id` for these. The field is absent when a generation for this app was already running, which is how you tell that case apart. example: 3 language: anyOf: - type: string - type: 'null' title: Language description: >- Language the copy was written in, as a lowercase two-letter code. It comes from the app's own site rather than from anything you send. The field is absent when a generation for this app was already running. example: de type: object required: - session_id - text - images title: GenerateAssetsResult description: The creative one generation produced.

It is a Base44 preview URL, not a Google one, and it stops resolving once the asset is cleaned up. example: https://storage.base44.com/gads-assets/b7f3a1c8-square.png source: type: string title: Source description: >- Which engine wrote it. The value is `google` for Google's own asset generation and `inhouse` for the Base44 model that covers languages Google does not generate for, and that stands in when Google's call fails. example: google language: anyOf: - type: string - type: 'null' title: Language description: >- Language of a text asset as a lowercase two-letter code, or `null` on an image, because image assets carry no copy. example: de channel_type: type: string title: Channel Type description: >- Campaign type the asset was generated for, one of `SEARCH`, `PERFORMANCE_MAX`, `DISPLAY` or `DEMAND_GEN`. example: PERFORMANCE_MAX created_at: type: string format: date-time title: Created At description: When the asset was generated. example: '2026-08-25T14:05:00Z' type: object required: - session_asset_id - asset_field_type - kind - text - image_url - source - language - channel_type - created_at title: GeneratedAssetSummary description: One generated asset in a live generation session. securitySchemes: ApiKeyAuth: type: apiKey in: header name: api_key description: Personal API key. ````
