# Create website conversion action

`POST /v1/ads/conversions/actions`

Creates a `WEBPAGE` conversion action (category `DEFAULT`) and returns it with
its tag snippets, read back after creation since Google never returns them on
the create response itself. Invalidates the cached list `GET` on this resource
would otherwise keep serving. Google-only; other platforms return `501`.
Requires the Ads add-on.

## Request body

- object
  - `accountId` string, required — SocialAccount ID. Must be a `googleads` account.
  - `customerId` string — Google Ads customer id (digits only). Resolved automatically when the connection has exactly one accessible customer.
  - `name` string, required
  - `type` 'WEBPAGE', required — Only WEBPAGE is supported for creation today.
  - `defaultValue` number — Default conversion value used when an event doesn't carry its own value.
  - `alwaysUseDefaultValue` boolean — When true, always use defaultValue and ignore any value sent with the event. Defaults to true when defaultValue is set.

## Response `201`

The created conversion action, with its tag snippets.

- object
  - `action` ConversionAction — A Google Ads conversion action, e.g. a WEBPAGE conversion created via `createConversionAction`. Returned by `listConversionActions` and `createConversionAction`.
    - `id` string, required — Google Ads conversion action id.
    - `name` string, required
    - `type` string, required — Google's ConversionActionType, e.g. WEBPAGE, UPLOAD_CLICKS.
    - `status` string, required — Google's ConversionActionStatus, e.g. ENABLED, REMOVED, HIDDEN.
    - `category` string, required — Google's ConversionActionCategory, e.g. DEFAULT, PURCHASE, LEAD.
    - `tagSnippets` object[], required — The code a customer pastes onto their site. Present for types Google generates a snippet for (e.g. WEBPAGE); empty otherwise.
      - `type` string, required — Google's TrackingCodeType, e.g. WEBPAGE.
      - `pageFormat` string — Google's TrackingCodePageFormat, e.g. HTML, AMP.

## Other responses
