# FAQ

Short answers to common questions.

<details>

<summary>Does the access token expire?</summary>

Yes. An access token lasts 7 days. Request a new token with the same call that you used for the first one. Your client ID and client secret do not expire. A missing, malformed or expired token returns `403`. Request a new token. See [Authenticate](/essentials/authenticate.md).

</details>

<details>

<summary>What do I send to support when a call fails?</summary>

Send the `X-Request-ID` response header of the call, with the time, the method, the path and the status code. See [Support](/resources/support.md).

</details>

<details>

<summary>How do I know that a load finished?</summary>

To check the status of a load, open the dataset in Abacum and go to the **Loads** tab. See [Load data](/guides/import-api-guides/load-data.md).

<summary>Do download links need my token?</summary>

No. A download link is a pre-signed URL. It works with no `Authorization` header until it expires. See [Download links](/essentials/concepts/download-links.md).

<details>

<summary>Can a Member use the API?</summary>

Yes, for `GET /public-api/me`, `GET /public-api/search` and the Spaces endpoints. Every other endpoint needs the Admin role. See [Access and permissions](/essentials/concepts/access-and-permissions.md).

<summary>Can I write data into a model through the API?</summary>

Model data comes from datasets. You load actuals into a dataset with `POST /public-api/load-data`. The Public API reads data. The Import API loads data into datasets. See [Access and permissions](/essentials/concepts/access-and-permissions.md).
