# Protocol & Format

## Protocols :tools:&#x20;

**Veasybl** supports several methods for retrieving product catalog files.

The files can be hosted on the retailer's server and downloaded using one of the standard protocols.

Currently, **Veasybl** supports file downloads via the following protocols:

* HTTPS (recommended)
* AWS S3
* Google Storage
* FTPS
* SFTP

You will need to provide information about the protocol, host, port, and file path of the catalog so that **Veasybl** can proceed with the download.

If authentication is required to access the product catalog, the retailer will need to provide the necessary credentials to **Veasybl** to enable secure access to the data.

If you wish to use an unsupported protocol, please contact our technical team to discuss available options.
{% endhint %}

## Format

To ensure that **Veasybl** can correctly retrieve your product catalog, please use the CSV format.

<table data-header-hidden><thead><tr><th width="146">Format </th><th>Détails</th></tr></thead><tbody><tr><td>Format </td><td>Description</td></tr><tr><td><strong>CSV</strong>            </td><td>This format uses values separated by a separator ( semicolon or pipe ). The header must be indicated on the first line of the file.</td></tr></tbody></table>
