I'm working on an api that receives notifications from the meta weebhook every time my page have changes. Currently its in test mode, I just want to test the webhook first. In the process I'm able to verify my callback link but once I want to test one of the fields nothing its send to my server. Feed field that I want to test I have a POST controller in my backend that should take care of the request and its working; How do I know that ? Because one of the only fields that sends a request it send_cart field. Send cart field There is one or two more fields that actually send a request, but 98% of them don't work. Im not sure if there an error on the Meta Graph API or I did something wrong. If anyone had this problem, or has an idea how I could solve it, it would be very helpful; because this should have been a simple project but it's taking me a week, and I'm already embarrassed. If more information its needed I'm gonna be responding all the requests. Thanks ! Below its the server code that I'm working with:

  • This is the controller:
exports.facebookWebhook = (req, res) => {   if(req.query["hub.verify_token"] === "my_token"){     res.status(200).send(req.query["hub.challenge"])   }else{     res.status(400).send({ message: "bad request" })   } } exports.facebookWebhookChanges = (req, res) => {   if (!req.body || Object.keys(req.body).length === 0) {     console.log('Received an empty request body');     res.status(400).send('Bad Request: Request body is empty');     return;   }   console.log(req.body)   res.status(200).send({ message: "Ok" }) }
  • This is the route:
  app.get("/api/facebook/webhook/", controller.facebookWebhook);   app.post("/api/facebook/webhook/", controller.facebookWebhookChanges);

I already read all the documentation to make sure Im doing everything good, I have read other people posts that doesnt match with my problem. I asked on facebook developer forum to.
