validateWebhookSignature()

Available from v3.2.30

Validates that the signature that was received by a webhook endpoint is authentic. If the validation fails, an error is thrown.

API​

The function accepts an object with three key-value pairs:

secret​

The same webhook secret that was passed to renderMediaOnLambda()'s webhook options.

body​

The body that was received by the endpoint.

signatureHeader​

The X-Remotion-Signature header from the request that was received by the endpoint.

Example​

In the following Next.JS webhook endpoint, an error gets thrown if the signature does not match the one expected one or is missing..

tsx
import {
  validateWebhookSignature,
  WebhookPayload,
} from "@remotion/lambda/client";
 
export default async function handler(
  req: NextApiRequest,
  res: NextApiResponse
) {
  validateWebhookSignature({
    secret: process.env.WEBHOOK_SECRET as string,
    body: req.body,
    signatureHeader: req.headers["x-remotion-signature"] as string,
  });
 
  // If code reaches this path, the webhook is authentic.
  const payload = JSON.parse(req.body) as WebhookPayload;
  if (payload.type === "success") {
    // ...
  } else if (payload.type === "timeout") {
    // ...
  }
 
  res.status(200).json({
