Vietnam. Ewallet payments

You can make local ewallet payments in Vietnam in Vietnamese dongs (VND).

No recurring payments are available.

Making a payment

1. Create a session using the session/create method.

   Alternatively, you can use the session/init/payment method. In this case, specify all the payment parameters right away and skip the next step.

2. Send a session/start/payment request. Specify the following parameters:

   • country_ewallet in internet_banking.type
   • country_iso2 in internet_banking.country_ewallet
   • the payer's full name and document in participant_details.sender
   • the payer's email in customer.reference.contacts
     Optionally, you can add a return URL to redirect the customer back after the payment (payment_options.return_url).

     https://partner.com \
     -H 'content-type: application/json' \
     -H 'X-PARTNER-SIGN: signature' \

         "acquiring_payments": [{
           "id": "pm_566184419",
           "status": "in_progress",
           "created_at": "2025-12-04T19:29:23.217101Z",

           }
         }]
      }
     }'

3. Wait for a ready_to_confirm webhook. When you receive it, it means that Smart Glocal is ready to make the payment and is waiting for your confirmation.

   Webhook example

   curl -X POST \
     https://partner.com \
     -H 'content-type: application/json' \
     -H 'X-PARTNER-SIGN: signature' \
     -d '{
       "type": "ready_to_confirm",
       "status": "ok",
       "session": {
         "id": "ps_5666",
         "status": "in_progress",
         "created_at": "2025-12-04T19:28:58.077701Z",
         "updated_at": "2025-12-04T19:29:23.216667Z",
         "acquiring_payments": [{
           "id": "pm_12354",
           "status": "in_progress",
           "created_at": "2025-12-04T19:29:23.217101Z",
           "customer": {
             "reference": "qwiqwi",
             "contacts": [{
               "email": "email@example.com"
             }]
           },
           "payment_details": {
             "type": "internet_banking",
             "internet_banking": {
               "type": "country_ewallet",
               "country_ewallet": {
                 "country_iso2": "VN"
               }
             }
           },
           "amount_details": {
             "amount": 100000,
             "currency": "VND"
           },
           "participant_details": {
             "sender": {
               "full_name": "Name Surname",
               "document": "12333315123"
             }
           },
           "payment_options": {
             "return_url": "https://smart-glocal.com/",
             "recurrent": false
           }
         }],
         "actions": {
           "confirm": "2025-12-04T07:48:28.275964Z"
         }
       }
     }'

4. Send a session/confirm request to confirm the operation or a session/cancel request to cancel it.

   Request example

   curl -X POST \
     https://demo.smart-glocal.com/api/v1/session/confirm \
     -H 'content-type: application/json' \
     -H 'X-PARTNER-PROJECT: your_project_name' \
     -H 'X-PARTNER-SIGN: signature' \
     -d '{
       "session_id":"ps_5666"
     }'

5. Wait for an action_required webhook. The customer_interaction.redirect.url parameter contains a deeplink to a QR code.

   Webhook example

   curl -X POST \
     https://partner.com \
     -H 'content-type: application/json' \
     -H 'X-PARTNER-SIGN: signature' \
     -d '{
       "type": "action_required",
       "status": "ok",
       "session": {
         "id": "ps_5666",
         "status": "in_progress",
         "created_at": "2025-12-04T07:48:28.296138Z",
         "updated_at": "2025-12-04T07:48:28.958891Z",
         "acquiring_payments": [{

           "customer": {
             "reference": "qwiqwi",
             "contacts": [{
               "email": "email@example.com"
             }]
           },
           "participant_details": {
             "sender": {
               "full_name": "Name Surname",
               "document": "12333315123"
             }
           },
           "payment_details": {
             "type": "internet_banking",
             "internet_banking": {
               "type": "country_ewallet",
               "country_ewallet": {
                 "country_iso2": "VN"
               }
             }
           },
           "amount_details": {
             "amount": 100000,
             "currency": "VND"
           },
           "customer_interaction": {
             "type": "redirect",
             "redirect": {
               "url": "https://redirect-url-example.com/12345",
               "base_url": "https://redirect-url-example.com/12345",
               "method": "GET",
               "params": {}
             }
           },
           "metadata": {
             "key": "value"
           },
           "payment_options": {
             "return_url": "https://smart-glocal.com/",
             "recurrent": false
           }
         }],
         "actions": {
           "confirm": "2025-12-04T07:48:28.327146Z"
         }
       }
     }'

   5.1 The user redirected by the link from the webhook lands on a page like this:

   

   5.2 The user selects a payment method and the QR code appears.

   

   5.3 After the user completes the payment, a message on successful payment appears.

   

6. After the customer makes the payment, you will receive a payment_finished webhook containing the payment result from Smart Glocal. The succeeded status indicates a successful payment.
