Google Ads

Query the Google Ads API via curl + jq. Two credentials plus one context header:

• $GOOGLE_ADS_TOKEN — the user's OAuth bearer (adwords scope) → Authorization: Bearer $GOOGLE_ADS_TOKEN
• $GOOGLE_ADS_DEVELOPER_TOKEN — the platform's developer token (injected server-side) → header developer-token: $GOOGLE_ADS_DEVELOPER_TOKEN
• login-customer-id — only for manager (MCC) scoped calls: the manager id the request runs under, or $GOOGLE_ADS_LOGIN_CUSTOMER_ID if set (digits only, no dashes). Not needed by customers:listAccessibleCustomers.

API version: the base is https://googleads.googleapis.com/<vNN>. Google ships a new vNN every ~4 months and retires old ones, so a hardcoded version eventually stops working. The example uses v25 (supported as of 2026-07). If every call 404s, the version is unavailable — either retired or not yet released. Probe customers:listAccessibleCustomers: a supported version answers 401/200, an unavailable one 404. Step down one version at a time from the example, and check Google's supported-versions table before assuming a newer vNN exists.

If $GOOGLE_ADS_DEVELOPER_TOKEN is empty, the connector isn't fully provisioned — say so rather than calling the API (it would 401/DEVELOPER_TOKEN_NOT_APPROVED).

VER="v25"; BASE="https://googleads.googleapis.com/$VER"
AUTH="Authorization: Bearer $GOOGLE_ADS_TOKEN"; DEV="developer-token: $GOOGLE_ADS_DEVELOPER_TOKEN"
# Customers the OAuth user can access (ids are returned as customers/<id>)
curl -sS -H "$AUTH" -H "$DEV" "$BASE/customers:listAccessibleCustomers" | jq '.resourceNames'

Report with GAQL (searchStream)

CID="1234567890"   # target customer id, digits only
# Manager (MCC) access → send login-customer-id; direct access → drop the header.
# Array, not a plain string: the header value contains a space and would split.
LOGIN=(); [ -n "$GOOGLE_ADS_LOGIN_CUSTOMER_ID" ] && LOGIN=(-H "login-customer-id: $GOOGLE_ADS_LOGIN_CUSTOMER_ID")
curl -sS -H "$AUTH" -H "$DEV" "${LOGIN[@]}" \
  -H "Content-Type: application/json" -d '{
  "query":"SELECT campaign.name, metrics.cost_micros, metrics.clicks, metrics.conversions FROM campaign WHERE segments.date DURING LAST_30_DAYS ORDER BY metrics.cost_micros DESC"
}' "$BASE/customers/$CID/googleAds:searchStream" \
  | jq '.[].results[]? | {campaign: .campaign.name, cost_usd: (.metrics.costMicros|tonumber/1e6), clicks: .metrics.clicks, conv: .metrics.conversions}'

GAQL resources: campaign, ad_group, ad_group_criterion (keywords), customer. Cost is metrics.cost_micros (÷ 1,000,000 = account currency).

Gotchas

• A 404 on every endpoint points at VER, not at credentials — the version is retired or unreleased. A 404 on a single call is about that call: a missing resource (bad customer id) or a wrong path. Sanity-check the version with customers:listAccessibleCustomers before debugging auth.
• Two credentials plus a context header. developer-token is required on every call; login-customer-id is only needed when acting under a manager (MCC) account — customers:listAccessibleCustomers works without it. Omitting it on a manager-scoped call is the #1 cause of 401/403 here.
• Customer ids are digits only in URLs/headers (strip the dashes from 123-456-7890).
• searchStream returns an array of chunks each with .results[] — flatten with .[].results[]?.
• Cost is in micros of the account currency; divide by 1e6.
