Webhook signature verification code

These code snippets provide functionality to verify the authenticity of webhook requests and to parse the payload data. It ensures that incoming webhook requests are from a trusted source by checking their signature and then processes the request data.

type PayoutWebhookEvent struct {
Type   string
Raw    string
Object interface{}
}

func PayoutVerifyWebhookSignature(signature string, rawBody string, timestamp string) (*PayoutWebhookEvent, error) {
signatureString := timestamp + rawBody
hmacInstance := hmac.New(sha256.New, []byte(*XClientSecret))
hmacInstance.Write([]byte(signatureString))
bytesData := hmacInstance.Sum(nil)
generatedSignature := base64.StdEncoding.EncodeToString(bytesData)
if generatedSignature == signature {
var object interface{}
err := json.Unmarshal([]byte(rawBody), &object)
if err != nil {
return nil, errors.New("something went wrong when unmarshalling raw body")
}
if objectAsMapInterface, ok := object.(map[string]interface{}); ok {
if webhookType, ok := objectAsMapInterface["type"].(string); ok {
return &PayoutWebhookEvent{Type: webhookType, Raw: rawBody, Object: object}, nil
}
}
return &PayoutWebhookEvent{Type: "", Raw: rawBody, Object: object}, nil
}
return nil, errors.New("generated signature and received signature did not match")
}

Webhook retries

Cashfree Payments webhooks service does its best to deliver events to your webhook endpoint. It is best practice for your application to respond to the callback. Our webhook service may send many payloads to a single endpoint in quick succession. You will need to build an application and configure your server to receive the response we send when events get triggered during the payout process.

Your server should return a 200 HTTP status code to acknowledge that you received the webhook without any issues. Any other information you return in the request headers or request body gets ignored. Any response code outside the 200 range, including 3xx codes, indicates that you did not receive the webhook.

When Cashfree Payments does not get the acknowledgement due to any reason, we retry to establish the communication at regular intervals. If we do not receive the response after few attempts, we gradually decrease the rate of retries. Based on this count, the service is disabled if it fails more than five times.

If do not receive notifications from Cashfree Payments as expected, please fill out the Support Form.
