Get And Update Settings File

Once the SDK is launched properly, there might be scenarios later on when you need to fetch the latest settings-file and use that instead of the stale one to sync SDK and VWO application. You can do this by calling Get Settings File API and passing the fetched settings-file to the Launch API to re-instantiate the VWO SDK. Or, you can simply use the Get and Update Settings File API, available on the VWO Client Instance that is already available.

Description

Get And Update Settings File API will fetch the latest settings-file from the VWO server and update the VWO Client Instance to use that. Every VWO SDK API used after this API will work according to the latest settings-file fetched.

The method accepts three parameters:

account_id - account-id associated with your VWO account.
sdk_key - generated inside the respective Project under the FullStack Testing.

Parameter Definitions

sdk_key Required	String	Unique environment-key provided to you inside the Projects section in VWO application..
is_via_webhook Optional	Boolean	VWO SDKs require this to handle webhook generated settings-file requests differently. Note: Only pass true when this API is used once the webhook is triggered.

Returns
