When the user completes the transfer via the QR code, the Gluwa API sends a webhook to your webhook endpoint. Verify that the values ​​were actually sent from the Gluwa server.‌
Verify the requested Signature and Payload as follows:
1
public void validateWebhook_test() {
2
Configuration conf = new ConfigurationForTest();
3
GluwaApiSDKImpl wrapper = new GluwaApiSDKImpl(conf);
4
boolean result = wrapper.validateWebhook(
5
"{Payload in Request's body}",
6
"{Signature in Request's header}");
