How can i get the raw body in api routes for webhook?

[balramxyadav]

I want to implement a webhook for a custom payment gateway, but no matter what I do, it doesn't work. I can never get the req.rawBody that the webhook requires. When I tried it with a normal Express server (sepreate from medusa), it worked perfectly, but for some reason, it's not working in Medusa. I tried the Express approach that didn't work, and then followed the routes approach Medusa recommends, and set up middleware as described here: https://docs.medusajs.com/development/api-routes/create#parse-webhook-body-parameters. But I still can't get the rawBody. Can someone help?

Please include a minimal reproduction of the issue, and we will attend to it.

Thanks for responding, quickly!

With the routes approach I tried:
/webhooks/test

import {
  MedusaRequest,
  MedusaResponse,
  ProductService,
} from "@medusajs/medusa";

export const POST = async (req: MedusaRequest, res: MedusaResponse) => {
  res.status(200);
  console.log("Body", req.body);
  console.log("Raw Body:", req.rawBody);
};

and middleware as:
/middlewares.ts

import {
  MedusaNextFunction,
  MedusaRequest,
  MedusaResponse,
  MiddlewaresConfig,
} from "@medusajs/medusa";
import { raw } from "body-parser";

export const config: MiddlewaresConfig = {
  routes: [
    {
      method: ["POST", "PUT"],
      matcher: "/webhooks/*",
      bodyParser: false,
      middlewares: [raw({ type: "application/json" })],
    },
  ],
};

But i got rawData as undefined. I want to get the rawData.

If you want to access the raw body as req.rawBody, you should set preserveRawBody: true in the middleware too. Otherwise, the raw body is assigned to the regular req.body.

It would look like this:

export const config: MiddlewaresConfig = {
  routes: [
    {
      method: ["POST", "PUT"],
      matcher: "/webhooks/*",
      bodyParser: { preserveRawBody: true },\
    },
  ],
};

I believe you can then omit raw(...) from the middlewares, but I'll have to test this later.

Can you give this a shot and let me know if it works?

I had tried it before, but i tried again but unfortunately, it doesn't work :/

Do you have another solution?

What payment provider is this?

[balramxyadav]

I am using Cashfree Payment. I didn't find any working plugin for it.

Can you let me know what you are seeing with preserveRawBody: true configured?

Also, if you want me to test this out, please provide a small reproduction in a repository.

Great, I'll check it out.

QQ: Is there a reason you haven't started with the preview version of Medusa 2.0? If you can, I would recommend that to avoid an upgrade in the near term.

It's because i already have built my entire website. I am working on the implementing the payment gateway. Is it production ready yet? I heard it goes production ready on 23rd or something.
