## FAQ

<details>

<summary>How to set up a custom source?</summary>

If your app isn’t listed among the available sources on Coupler.io, you can still connect it through a custom source as long as it exposes data as JSON or CSV.

You can use one of these options:

* [JSON data source](https://docs.coupler.io/sources/category/files-and-tables/json)
* [CSV data source](https://docs.coupler.io/sources/category/files-and-tables/csv)

Feel free to reach out to our Support Team at <contact@coupler.io>, if you need help with the setup.

</details>

<details>

<summary>How to request a source to be added?</summary>

You can directly submit any requests in our [Featurebase](https://feedback.coupler.io/). You can upvote the input and add a comment about the scenario where you'd be using this source and what you'd like to achieve. There is also a roadmap that enables progress tracking.

</details>

<details>

<summary>Does Coupler.io support custom properties when pulling data from sources?</summary>

Yes. If the source app exposes custom fields through its API, Coupler.io can usually pull them too. Some sources (such as HubSpot, Pipedrive, and ClickUp) automatically include custom properties in the data export without any additional configuration.

Since custom property behavior is source-specific, we recommend reviewing the data export first. If you cannot spot the needed fields, please contact our support team at <contact@coupler.io>, and we'll be happy to assist on a case-by-case basis.
