multiparty vendor

[auqid]

I am integrating PayPal into a multi-vendor site where the payment workflow is designed to:

1. Authorize payment when a customer requests a service.
2. Capture payment when the seller accepts the request.
3. Disburse payment to the seller upon service completion.

Steps and Issues:

1. Order Creation:

   • Intent: 'authorize'
   • Custom Reference ID: Generated using a custom function.
   • Payload:
     const paypalRequest = {
     intent: 'AUTHORIZE',
     purchase_units: [
     {
     reference_id: generateCustomReferenceID(),
     amount: {
     currency_code: currentCurrency,
     value: toMoney(totalPayin),
     breakdown: {
     item_total: {
     currency_code: currentCurrency,
     value: toMoney(totalPayin),
     },
     },
     },
     payee: {
     email_address: payeePaypalEmail,
     },
     items: lineItems
     .filter(k => k.code != 'line-item/provider-commission')
     .map(item => ({
     name: findPaypalItemLabel(item),
     quantity: item.quantity,
     unit_amount: {
     currency_code: currentCurrency,
     value: toMoney(item.unitPrice.amount),
     },
     })),
     },
     ],
     };
     
     Order Creation Request:
     const orderResponse = await createOrder(paypalRequest);
     
     

     Payment Authorization:

     • Authorization Request:
       const [success, error] = await authorizePayment(orderID);
       const authorizationId = success?.purchase_units[0]?.payments?.authorizations[0]?.id;
       const reference_id = success?.purchase_units[0]?.reference_id;
       if (error) {
       return res.status(500).send({ message: 'Order id is not present.' });
       }
       

       Payment Capture (upon seller acceptance):

       • Payload:
         
       • const payload = {
         payment_instruction: {
         disbursement_mode: 'DELAYED',
         platform_fees: [
         {
         amount: {
         currency_code: currentCurrency,
         value: '10',
         },
         },
         ],
         },
         };
       • Capture Request:
         const captureURL = `/v2/payments/authorizations/${authorizationId}/capture`;
         const response = await axiosWithPaypal.post(captureURL, payload);
         Disbursement (upon service completion):
         
         
       • const res = await axiosWithPaypal.post('/v1/payments/referenced-payouts-items', {
         "reference_id": reference_id,
         "reference_type": "TRANSACTION_ID"
         }, {
         headers: {
         'Content-Encoding': 'gzip',
         'Prefer': 'respond-async',
         'PayPal-Request-Id': 'some-idempotency-data'
         },
         });
         
       • Issue: The disbursement request returns a 202 response, indicating success, but no funds are transferred from the buyer's account to the seller's account in the sandbox environment.
