# List Optimize IDs

GET https://api.webflow.com/v2/optimize

Lists the `optimizeId` values the provided access token can access, and the resource each one comes from, such as a Webflow site or a non-Webflow site. Use an `optimizeId` with the other Optimize endpoints.Results are sorted by `optimizeId` and aren't paginated.Webflow sites accept OAuth app tokens and Site API tokens. Non-Webflow sites that use Optimize accept only OAuth app tokens, including tokens authorized for a whole workspace.This endpoint requires a Webflow site with the Optimize add-on, or a non-Webflow site that uses Optimize.Each access token can have one Optimize request in flight at a time, across all Optimize endpoints. Additional concurrent requests return `429 Too Many Requests`. Wait for your in-flight request to finish, or for the `Retry-After` interval, then retry.Required scope | `sites:read`

## Types

### OptimizeGetResponsesContentApplicationJsonSchemaReferencesItems

An `optimizeId` the access token can access, and the resource it comes from.

- `optimizeId` (string, required) — The ID of an Optimize configuration, which holds its optimizations, goals, audiences, and settings. Use it with the other Optimize endpoints.
- `resource` (OptimizeGetResponsesContentApplicationJsonSchemaReferencesItemsResource, required) — The resource the `optimizeId` comes from. `type` identifies which kind.

### OptimizeGetResponsesContentApplicationJsonSchemaDetailsItems

### OptimizeGetResponsesContentApplicationJsonSchemaReferencesItemsResource

The resource the `optimizeId` comes from. `type` identifies which kind.

### Webflow site

A Webflow site.

- `type` (enum, required) — Identifies the resource as a Webflow site.
  - Allowed values: `webflow-site`
- `siteId` (string, required) — The Webflow site ID.
- `workspaceId` (string, required, nullable) — The ID of the workspace the site belongs to.
- `displayName` (string, required) — The site's display name.

### Optimize on a non-Webflow site

A non-Webflow site that uses Optimize.

- `type` (enum, required) — Identifies the resource as a non-Webflow site that uses Optimize.
  - Allowed values: `optimize-site`
- `optimizeSiteId` (string, required) — The ID of the non-Webflow site.
- `workspaceId` (string, required, nullable) — The ID of the workspace the site belongs to.
- `name` (string, required, nullable) — The site's name.
