I am having trouble with consuming data from a webhook from a CRM. I am receiving data from the CRM webhook and then I am trying to post that data to a facebook endpoint but in production when that API function is called it shows as a GET request instead of a POST request

 
import type { NextApiRequest, NextApiResponse } from 'next'
const pipedrive = require('pipedrive');


export default async function handler(
  req: NextApiRequest,
  res: NextApiResponse
) {

 const {v, matches_filters, meta, event } = req.body

 console.log({v, matches_filters, meta, event })

 const url = new URL(`https://graph.facebook.com/v17.0/${process.env.FB_PIXEL_ID}/events?access_token=${process.env.FB_ACCESS_TOKEN}`)

 const response = await fetch(url, {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    "data": [
      {
        "event_name": "Lead",
        "event_time": Date.now(),
        "action_source": "system_generated",
        "user_data": {
          "lead_id": meta.id,
          "client_ip_address": meta.remote_ip,
        },
        "custom_data": {
          "lead_event_source": "Pipedrive",
          "event_source": "crm",
          "event": event
        },

      }
    ],

  })
 } )



 const leadResponse = await response.json()


  res.status(200).json({message: 'Done', lead: leadResponse})
}
