# Create keywords

`POST /ad_accounts/{ad_account_id}/keywords`

## Request

- Base URL: `https://api.pinterest.com/v5`
- URL: `https://api.pinterest.com/v5/ad_accounts/{ad_account_id}/keywords`
- Auth: OAuth 2
  - Authorization code: `https://www.pinterest.com/oauth/`

- TypeScript: <https://skmtc.dev/pinterest/apis/pinterest-rest-api/docs/ad_accounts/:ad_account_id/keywords/post.ts> (a function with typed inputs; its response is checked against the schema)

Create keywords for the following entity types (advertiser, campaign, ad group, or ad). For more information, see [Keyword targeting](https://help.pinterest.com/en/business/article/keyword-targeting).

  **Notes:**
  - Advertisers and campaigns can only be assigned keywords with excluding (`_NEGATIVE`).
  - All keyword match types are available for ad groups.

  For more information on match types, see [match type enums](/docs/api-features/targeting-overview/).

  **Returns:**
  - A successful call returns an object containing an array of new keyword objects and an empty `errors` object array.
  - An unsuccessful call returns an empty keywords array, and instead, inserts the entire object with nulled/negated properties into the `errors` object array:
    ```json
    {
      "keywords": [],
      "errors": [
        {
          "data": {
            "archived": null,
