# Read TikTok advertiser settings before comparing anything

> Tier: recipe. Operating recipe: real tool sequence, core rules, known traps.

Advertiser-level settings read first, so multi-advertiser tables merge honestly.

**Intent.** Currency, timezone and status per advertiser, the merge prerequisites.

## When to use

- Multi-advertiser workspaces.
- Onboarding.

## When not to use

- No specific contraindication beyond the preconditions below.

## Sources

Required: TikTok Ads

## Preconditions

- The account is ticked in the dashboard, confirmed via list_accounts.

## Inputs

- `window`: Analysis window. Default: last 30 days.

## Procedure

1. Pull advertiser info for the ticked advertisers. — tools: `tiktok_get_advertiser_info`, `tiktok_list_advertisers`
2. Record currency and timezone per advertiser for every later merge.

## Decision rules

- **When** Advertisers differ in currency → **conclude** Every merged number must convert or label: set the rule before the first table.

## Evidence requirements

- Every figure carries its account, metric and window.
- Anything below a readable sample size is reported as unjudged, not as zero.

## Human approval boundary

- The readout changes nothing. Any change it motivates goes through Safe Writes: preview, human confirmation, then apply.

## Failure modes

- Timezone offsets shift 'yesterday' between advertisers: date boundaries are per-advertiser facts.

## Output

- **Readout**: The figures, with windows and accounts named.
- **Flags**: What deserves a deeper skill or a human decision.
