# Aprobar solicitud de vinculación o verificación del titular de la tarjeta

### Aprobar vinculación

Para aprobar una solicitud de vinculación de dispositivo, llama a `DigitalCardService.approveBinding` con `digitalCardID` y `bindingReference`.

Los siguientes ejemplos muestran cómo aprobar una solicitud de vinculación.

{% tabs %}
{% tab title="Android" %}

```kotlin
val digitalCardID = "" // tokenReferenceID del payload
val bindingReference = "" // deviceIndex del payload
val reason: DigitalCardService.BindingApprovalReason? =
    DigitalCardService.BindingApprovalReason.USER_DECISION // opcional; null usa por defecto ISSUER_DECISION

d1Task.digitalCardService().approveBinding(
    digitalCardID,
    bindingReference,
    reason,
    object : D1Task.Callback<Void> {
        override fun onSuccess(data: Void?) {
            // Gestionar el éxito.
        }

        override fun onError(e: D1Exception) {
            // Gestionar el error.
        }
    }
)
```

```java
String digitalCardID = ""; // tokenReferenceID del payload
String bindingReference = ""; // deviceIndex del payload
DigitalCardService.BindingApprovalReason reason =
        DigitalCardService.BindingApprovalReason.USER_DECISION; // opcional; null usa por defecto ISSUER_DECISION

d1Task.digitalCardService().approveBinding(
        digitalCardID,
        bindingReference,
        reason,
        new D1Task.Callback<Void>() {
            @Override
            public void onSuccess(Void data) {
                // Gestionar el éxito.
            }

            @Override
            public void onError(@NonNull D1Exception exception) {
                // Gestionar el error.
            }
        });
```

{% endtab %}

{% tab title="iOS" %}

```swift
do {
    let digitalCardID = "" // tokenReferenceID del payload
    let bindingReference = "" // deviceIndex del payload

    try await d1Task.digitalCardService().approveBinding(digitalCardID, bindingReference: bindingReference, reason: nil)
} catch let error {
    // Gestionar el error.
}
```

{% endtab %}
{% endtabs %}

### Aprobar verificación del titular de la tarjeta

Para aprobar una solicitud de verificación del titular de la tarjeta, llama a `DigitalCardService.approveCardholderVerification` con `digitalCardID`.

Los siguientes ejemplos muestran cómo aprobar una solicitud de verificación del titular de la tarjeta.

{% tabs %}
{% tab title="Android" %}

```kotlin
val digitalCardID = "" // obtenido de VISA CTF
val reason: DigitalCardService.VerificationReason? = null // opcional; null usa por defecto ISSUER_DECISION

d1Task.digitalCardService().approveCardholderVerification(
    digitalCardID,
    reason,
    object : D1Task.Callback<Void> {
        override fun onSuccess(data: Void?) {
            // Gestionar el éxito.
        }

        override fun onError(e: D1Exception) {
            // Gestionar el error.
        }
    }
)
```

```java
String digitalCardID = ""; // obtenido de VISA CTF
DigitalCardService.VerificationReason reason = null; // opcional; null usa por defecto ISSUER_DECISION

d1Task.digitalCardService().approveCardholderVerification(
        digitalCardID,
        reason,
        new D1Task.Callback<Void>() {
            @Override
            public void onSuccess(Void data) {
                // Gestionar el éxito.
            }

            @Override
            public void onError(@NonNull D1Exception exception) {
                // Gestionar el error.
            }
        });
```

{% endtab %}

{% tab title="iOS" %}

    let digitalCardID = "" // obtenido de VISA CTF

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.payments.thalescloud.io/push-provisioning/es/implement-push-provisioning/implement-view-and-control/in-app-authentication-for-visa-ctf/approve-binding-or-cardholder-verification-request.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
