# Supported Browsers & Recommendations

The VIDA Web SDK officially supports the browser versions listed in the Supported Browsers matrix below. These are the versions VIDA actively tests against and fixes bugs in. Older versions of the same browsers may continue to function in practice but are outside the scope of active testing and support.

The SDK performs runtime capability checks during the process. If the browser does not meet the technical requirements, the SDK surfaces error code **70003** (`browser or device doesn't support this functionality`) via the `onError` callback and displays an "Unable to proceed" screen to the end user.

## Secure Storage and API Call Recommendations

**Server-Side Storage:**

* Store the `client_id` and `client_secret` securely on your server.
* **Do not expose** these credentials on the client-side.

**Server-to-Server Communication:**

* The API call to obtain the bearer token must be made **from your server** to Vida's server, ensuring secure communication.

**Signing Key:**

* Vida will provide a **signing key** along with the `client_id` and `client_secret`.
* Store the signing key securely on your server.

***

When initialising the Vida SDK:

1. **Obtain the Bearer Token**
   * Use the provided credentials to obtain a bearer token securely from your server.
2. **Retrieve the Signing Key**
   * Retrieve the signing key that was securely stored on your server.
3. **Pass Token and Signing Key to SDK**
   * Provide both the bearer token and signing key when initialising the Vida SDK by passing them to the `init` method.
