## Inspect the schema

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

```bash
oo connector schema "formbricks" --action "list_contact_attribute_keys"
```

## Run

```bash
oo connector run "formbricks" --action "list_contact_attribute_keys" --data '{}' --json
```

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