## Inputs

| Field                | Type                       | Required | Default | Description                                                                                                                                                                                                                                                                 |
| -------------------- | -------------------------- | -------- | ------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `ad_group_id`        | string or SelectableOption | Yes      | -       | Ad group ID to update (from openai\_ads\_list\_ad\_groups).                                                                                                                                                                                                                 |
| `billing_event_type` | string or SelectableOption | Yes      | -       | Bid / billing event type. Must match the parent campaign's objective: 'impression' for an impressions campaign, 'click' for both clicks and conversions campaigns (for a conversions/oCPC campaign the bid amount is the target CPA).                                       |
| `strategy`           | string or SelectableOption | No       | -       | Bidding strategy: 'fixed\_bid' (the default if omitted) bids the bid\_amount; 'maximize\_clicks' / 'maximize\_conversions' bid automatically, making bid\_amount optional.                                                                                                  |
| `bid_amount`         | number                     | No       | -       | Maximum bid in account currency, not micros. This value is converted to micros automatically before sending to the API. Required unless strategy is 'maximize\_clicks' or 'maximize\_conversions'. For a conversions (oCPC) campaign this is the target CPA per conversion. |

### SelectableOption

| Field   | Type   | Required | Default | Description |
| ------- | ------ | -------- | ------- | ----------- |
| `value` | string | Yes      | -       |             |
| `label` | string | Yes      | -       |             |
