Stripe Webhook Signature

I am sending stripe webhooks to a buildship workflow that will update my DB with webhook events. The code continually fails with an error as follows: Error: Webhook payload must be provided as a string or a Buffer (https://nodejs.org/api/buffer.html) instance representing the raw request body.Payload was provided as a parsed JavaScript object instead. Signature verification is impossible without access to the original signed material. Learn more about webhook signing and explore webhook integration examples for various frameworks at https://github.com/stripe/stripe-node#webhook-signing No matter what changes I make to my code to try and send it as raw body, I cannot get it to work in BS. Can anyone look at my code and let me know if there is anything glaringly obvious, or if it simply cannot be done?

The issue with integrating Stripe webhooks into your BuildShip workflow appears to stem from the need for the webhook payload to be provided as a raw string or Buffer instance. This is necessary for signature verification, which is crucial for ensuring the integrity and security of the webhook data. The following information was found within the provided documents, which might address your problem: - It has been noted that dealing with binary data (such as Buffer instances) can occasionally necessitate specific handling within nodes to ensure that data integrity is maintained . - The challenge of correctly processing input from webhooks, especially when the payload format is specifically required, is a common concern . Given these insights, it seems that making sure to handle the incoming webhook data at the lowest level (i.e., ensuring it is treated as binary data right from the start and not converted prematurely) is crucial. You might need to ensure that your BuildShip nodes or any middleware you are using does not automatically parse the payload into objects before it reaches the signature verification step. I recommend ensuring your webhook handler in BuildShip explicitly receives the request body as raw data and does not parse it. You might need to use a buffer or string to store the raw body:

let rawBody = '';
req.on('data', (chunk) => {
  rawBody += chunk.toString(); // convert Buffer to string
});

req.on('end', () => {
  // Use rawBody for signature verification
});

let rawBody = '';
req.on('data', (chunk) => {
  rawBody += chunk.toString(); // convert Buffer to string
});

req.on('end', () => {
  // Use rawBody for signature verification
});

If you've tried these steps and are still encountering issues, it might be beneficial to reach out for personalized debugging through BuildShip's in-app support for more targeted assistance. For more information on handling raw payloads in webhooks, refer to Stripe's webhook documentation.
