RECIPE: Install Google Ads and Create an Account

Setting up Google Ads on a Wix site is a strict two-step prerequisite for everything else in this area: (1) install the Wix Google Ads app, then (2) create the Google Ads account. Campaigns, suggestions, analytics, and billing all fail with ACCOUNT_NOT_FOUND (or an app-not-installed error) until both are done. This is a one-time setup per site.

Base URL for all endpoints: https://www.wixapis.com/google-ads/v1. The <AUTH> placeholder is shorthand for the Authorization header; body-bearing calls also need Content-Type: application/json.

STEP 0: Check whether an account already exists (do this first)

Before installing or creating anything, check for an existing account. Get Account For Current Site returns an empty response (not an error) when none exists, so it's the safe probe.

• account present → setup is already done. Skip to whatever the user actually wants (create a campaign, view analytics, etc.). Do not create a second account — Create Account returns ACCOUNT_ALREADY_EXISTS.
• Empty response {} → no account yet. Continue to STEP 1.

Example response for an existing account:

account.id is the Wix-internal GUID used as campaign.accountId when creating campaigns. googleAccountId is the underlying Google Ads customer ID (display only). currentBudget is remaining ad credit — a negative value means outstanding debt not yet charged.

STEP 1: Install the Wix Google Ads app

Idempotent — safe to call even if already installed (no effect). Required before Create Account.

Returns {}. Always run this before the first Create Account on a site.

STEP 2 (optional): Offer a promotional incentive

New accounts in supported currencies can attach an incentive — a promotional credit granted after the account spends a threshold. Skip this step for unsupported currencies (the call returns no offers).

Returns up to three tiers (lowOffer, mediumOffer, highOffer), each with an incentiveId, an awardAmount (credit granted), and a requiredAmount (spend needed to unlock it), plus a consolidatedTermsAndConditionsUrl. Present the tiers to the user and let them pick; carry the chosen incentiveId into STEP 3 as selectedIncentiveId. The incentive is recorded now and applied automatically once the account's budget is assigned — there is no separate apply call in this flow.

STEP 3: Create the Google Ads account

Requires currency (ISO-4217, e.g. USD). Pass selectedIncentiveId if the user picked one in STEP 2. Confirm with the user before this call — it provisions a billable account.

Response — save account.id for campaign creation:

The currency choice is durable and drives budget minimums/maximums and manager-account selection — settle it with the user before creating. A currency Google doesn't natively support (only USD, EUR, GBP, JPY are native) still works; the account reports budgetInSupportedCurrency as the converted amount.

Managing an existing account

Link a Google Merchant Center account (for Shopping / retail PMAX)

UpdateAccount is a partial update — send only the fields you're changing. Merchant Center linking is needed before a retail Performance Max campaign can serve product ads.

The response's merchantCenterAccountLinkStatus.status starts at PENDING — the Merchant Center account owner must approve the link before it becomes ENABLED.

View conversion actions

Conversion actions (Purchase, Page View, etc.) are what campaigns optimize toward. To inspect them:

Delete the account

DeleteAccount unlinks and removes the account. This is destructive and cannot be undone — always confirm with the user first, and prefer pausing campaigns over deleting the whole account when the user just wants to stop spending.

Returns {}. Errors with ACCOUNT_NOT_FOUND if no account exists.
