# Bizum for API only

Add Bizum to your API-only integration.

[View source](/payment-methods/bizum/api-only.md)

You can add Bizum to your existing integration. The following instructions show only what you must add to your integration specifically for Bizum.

If an instruction on this page corresponds with a step in the main integration guide, it includes a link to corresponding step of the main integration guide.

## Requirements

| Requirement           | Description                                                                                                                                                                                                                |   |
| --------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | - |
| **Integration type**  | Make sure that you have an existing [API-only integration](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only).                                                                   |   |
| **Redirect handling** | Make sure that your existing integration is set up to [handle the redirect](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#handle-the-redirect). `action.type`: **redirect**. |   |
| **Setup steps**       | Before you begin:- [Activate Bizum](/payment-methods/bizum#activate) to get your MID and Terminal ID.
- [Add Bizum in your Customer Area](/payment-methods/add-payment-methods).                                           |   |

## How it works

1. The shopper selects Bizum as the payment method.
2. The shopper enters their details in the [payment form that you build](#build-your-payment-form).
3. When you make the payment request, you [include additional information about the items that the shopper intends to purchase](#additional-parameters-payments).
4. Your existing integration setup will [handle the redirect](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#handle-the-redirect).

## Build your payment form

Include Bizum in the list of available payment methods. There are no additional fields that you have to include in your form.

You can [download the logo for Bizum](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%2Bonly\&version=71#downloading-logos) to use in your form.

## Get Bizum as an available payment method

When you make the [/paymentMethods](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods) to [get available payment methods](/online-payments/build-your-integration/advanced-flow/?platform=Web\&integration=API%20only#get-available-payment-methods), specify the following so that Bizum is included in the response.

| Parameter                                                                                                          | Values  |
| ------------------------------------------------------------------------------------------------------------------ | ------- |
| [countryCode](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-countryCode)         | **ES**  |
| [amount.currency](https://docs.adyen.com/api-explorer/Checkout/latest/post/paymentMethods#request-amount-currency) | **EUR** |

};

// Send the request
const checkoutAPI = new CheckoutAPI(client);
const response = checkoutAPI.PaymentsApi.payments(paymentRequest, { idempotencyKey: "UUID" });
```

The response includes `action.type`: **redirect**.

**Example response with a redirect action**

```json
{
    "resultCode": "RedirectShopper",
    "action": {
        "paymentMethodType": "bizum",
        "url": "https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=...",
        "data": {
            "Ds_MerchantParameters": "eyJEU19NRVJDSEFOVF9BTU9V…",
            "Ds_Signature": "17XXXYYY",
            "Ds_SignatureVersion": "T25V1"
        },
        "method": "POST",
        "type": "redirect"
    }
}
```

## Handle the redirect

1. To complete the payment, make a `POST` request with the following elements:

   * Redirect the shopper to the `action.url` returned in the [/payments](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments) response.

   * Use content type `x-www-form-urlencoded` to include the parameters from the `data` object as key-value pairs.\
     Bizum requires the `x-www-form-urlencoded` content type.

     **Redirect shopper**

     ```bash
     curl https://checkoutshopper-test.adyen.com/checkoutshopper/checkoutPaymentRedirect?redirectData=... \
     -X POST \
     -H 'x-api-key: ADYEN_API_KEY' \
     -H "content-type: application/x-www-form-urlencoded" \
     -d '{
         "Ds_MerchantParameters": "eyJEU19NRVJDSEFOVF9BTU9V…",
         "Ds_Signature": "17XXXYYY",
         "Ds_SignatureVersion": "T25V1"
     }'
     ```

2. After the shopper is redirected back to your website, check the payment result by making a `POST` [/payments/details](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details) request, specifying:

   * `details`: Object that contains the URL-decoded `redirectResult` returned when the shopper was redirected back to your site.

     **/payments/details request (check the payment result)**

     #### curl

     ```bash
     curl https://checkout-test.adyen.com/v72/payments/details \
     -H 'x-api-key: ADYEN_API_KEY' \
     -H 'content-type: application/json' \
     -d '{
         "details": {
           "redirectResult": "eyJ0cmFuc1N0YXR1cyI6IlkifQ=="
          }
     }'

   You receive a `/payments/details` response containing:

   * `resultCode`: Use this to present the result to your shopper.
   * `pspReference`: Our unique identifier for the transaction.

   **/payments/details response**

   ```json
   {
     "resultCode": "Authorised",
     "pspReference": "V4HZ4RBFJGXXGN82"
   }
   ```

## Show the payment result

Use the `resultCode` that you received in the [/payments/details](https://docs.adyen.com/api-explorer/Checkout/latest/post/payments/details) response to present the payment result to your shopper.

You can receive the following `resultCode` values for Bizum:

| resultCode                  | Description                                                                                                                                                                                                                                         | Action to take                                                                                                                                                                                                                         |
| --------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **Authorised**              | The shopper completed their payment, and it has been sent to the bank for processing. In most cases, this means that you will receive the funds. If you are using manual capture, you also need to [capture the payment](/online-payments/capture). | Inform the shopper that the payment has been successful.                                                                                                                                                                               |
| **Cancelled**               | The shopper cancelled the payment while on their bank's website.                                                                                                                                                                                    | Ask the shopper whether they want to continue with the order, or ask them to select a different payment method.                                                                                                                        |
| **Pending** or **Received** | The shopper has completed the payment but the final result is not yet known.                                                                                                                                                                        | Inform the shopper that you have received their order, and are waiting for the payment to be completed. You will receive the final result of the payment in an [AUTHORISATION webhook](/development-resources/webhooks/webhook-types). |
| **Refused**                 | The payment was refused by the shopper's bank.                                                                                                                                                                                                      | Ask the shopper to try the payment again using a different payment method.                                                                                                                                                             |

You also receive the outcome of the payment asynchronously in a [webhook](/development-resources/webhooks). If the shopper failed to return to your website or app, wait for notification webhooks to know the outcome of the payment. You can receive the following webhooks for Bizum:

| eventCode         | success field | Description                                     | Action to take                                                                      |
| ----------------- | ------------- | ----------------------------------------------- | ----------------------------------------------------------------------------------- |
| **AUTHORISATION** | **false**     | The transaction failed.                         | Cancel the order and inform the shopper that the payment failed.                    |
| **AUTHORISATION** | **true**      | The shopper successfully completed the payment. | Inform the shopper that the payment has been successful and proceed with the order. |

## Test and go live

To test Bizum payments:

* Use `telephoneNumber`: **700 000 000**.

* Note that the `amount` of the payment determines the outcome:

  | Amount       | Outcome               |
  | ------------ | --------------------- |
  | Less than 10 | Payment is authorized |
  | More than 15 | Payment is refused    |

* Check the status of Bizum test payments in your **Customer Area** > **Transactions** > **Payments**.
