## Inspect the schema

Always fetch the authoritative input/output schema before building a payload — fields and defaults can change upstream:

```bash
oo connector schema "tiktok_business" --action "check_gmv_max_shop_ad_usage"
```

## Run

```bash
oo connector run "tiktok_business" --action "check_gmv_max_shop_ad_usage" --data '{}' --json
```

Replace `{}` with a JSON object that matches the input schema. The response is `{ "data": ..., "meta": { "executionId": "..." } }`.
