Google Ads via treg — the traps

Verified live on 2026-07-22 against a live account, via treg call google-ads. Each trap is tagged with how many independent agents hit it when working without this file, so you know which are real and which are here for insurance.

Account id: treg connections ls → the google-ads row; treg connections resources <id> to list. Never guess an account id — you may be spending someone else's money.

1. Pin the API version — there is no discovery ⚠️ 2/2 agents hit this

Paths are versioned and a wrong guess returns a Google HTML 404, not JSON. Nothing in the API or in treg tool ls reports the current version — one agent burned five calls walking v14→v18 before recovering the answer from the treg calls audit log.

Use v21 (verified 2026-07-22). If it 404s, check the release notes; do not guess downward.

2. contains_eu_political_advertising is required on campaign create ⚠️ 3/3 hit this
