# List tags across groups

> List tags across one or more tag groups as a flat array.

Lists tags across one or more tag groups as a single flat array, ordered by `createdAt` descending.

## Headers

<ParamField header="Authorization" type="string" required>
  Bearer token containing your Fini workspace API key. Format: `Bearer fini_...` The key needs `read` scope.
</ParamField>

## Query parameters

<ParamField query="tagGroupIds" type="array" required>
  One or more tag group IDs. Pass repeated query params such as `?tagGroupIds=id1&tagGroupIds=id2`. This route does not accept a comma-separated CSV string.
</ParamField>

<RequestExample>
  ```bash cURL theme={null}
  curl --request GET \
    --url 'https://api-prod.usefini.com/v2/tag-groups/tags/public?tagGroupIds=4fbcebbd-693d-4fb8-84b2-c8fd0edee4c5&tagGroupIds=f770d0bb-d5ea-44e7-a92a-fcfa2d5a32d5' \
    --header 'Authorization: Bearer fini_your_api_key'
  ```

  ```python Python theme={null}
  import requests

  response = requests.get(
      "https://api-prod.usefini.com/v2/tag-groups/tags/public",
      headers={"Authorization": "Bearer fini_your_api_key"},
      params=[
          ("tagGroupIds", "4fbcebbd-693d-4fb8-84b2-c8fd0edee4c5"),
          ("tagGroupIds", "f770d0bb-d5ea-44e7-a92a-fcfa2d5a32d5"),
      ],
  )
  tags = response.json()
  ```

  ```javascript Node.js theme={null}
  const params = new URLSearchParams();
  params.append("tagGroupIds", "4fbcebbd-693d-4fb8-84b2-c8fd0edee4c5");
  params.append("tagGroupIds", "f770d0bb-d5ea-44e7-a92a-fcfa2d5a32d5");

  const response = await fetch(
    `https://api-prod.usefini.com/v2/tag-groups/tags/public?${params.toString()}`,
    {
      headers: {
        Authorization: "Bearer fini_your_api_key",
      },
    }
  );
  const tags = await response.json();
  ```
</RequestExample>

## Response

The response is a top-level array of [`Tag`](/en/api-reference/tags#tag-object) objects. The response is not grouped by `tagGroupId`; if you need grouped data, regroup the flat array client-side.
