# Verify SSL certificate

The **Verify SSL certificate** option ensures that Data Fetcher verifies the API's SSL certificate when making a request. This helps confirm that the connection is secure and that the server you are connecting to is trusted.

In most cases, this setting should remain enabled.

## When to disable SSL verification

Disable **Verify SSL certificate** only if the API you are connecting to uses a **self-signed SSL certificate**. Some internal or private APIs use self-signed certificates, which can cause SSL verification to fail.

If SSL verification fails, you may see errors such as:

* `self signed certificate`
* `unable to verify the first certificate`

Turning this option off allows the request to proceed without validating the certificate.

<Warning>
  Disabling SSL verification reduces connection security. Only disable this option if you trust the API you are connecting to.
</Warning>

## How to enable or disable it

1. Navigate to the request screen in Data Fetcher.
2. Open **Advanced settings**.
3. Scroll down and toggle **Verify SSL certificate** on or off.
