# Delete device binding

Delete a device binding from a merchant application using the Thales SDK.

## Flow

<figure><img src="/files/KCOCqqMUtYv2bIeUD3rX" alt=""><figcaption><p>App-initiated device binding deletion flow.</p></figcaption></figure>

<table><thead><tr><th width="100">Step</th><th>Description</th></tr></thead><tbody><tr><td>1</td><td>The merchant application calls the Thales SDK to delete the device binding for the token.</td></tr><tr><td>2-4</td><td>The Thales backend sends the deletion request to the payment network which coordinates the deletion with the issuer backend.</td></tr><tr><td>5-6</td><td>The Thales SDK returns the result to the merchant application.</td></tr><tr><td>7</td><td>The Thales backend sends a notification to the merchant or PSP backend.</td></tr></tbody></table>

## SDK integration

Call `removeBinding` and handle the result in `onSuccess` or `onError`.

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

```java
mastercardTAFHelper.removeBinding(tokenID, correlationID, new RemoveBindingListener() {
    @Override
    public void onError(TMGClientException tmgClientException) {
        // Handle error
    }

    @Override
    public void onSuccess() {
        // Update local binding state if needed
    }
});
```

{% endtab %}

{% tab title="iOS" %}

```swift
mastercardTAFHelper.removeBinding(forTokenID: tokenID,
                                  correlationID: correlationID) { error in
    if error == nil {
        // Update local binding state if needed
    } else {
        // Handle error
    }
}
```

{% endtab %}
{% endtabs %}

## Backend integration

The Thales backend notifies your merchant or PSP backend when the device binding is deleted.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.payments.thalescloud.io/merchant-tokenization/mastercard-taf/implement-taf/delete-device-binding.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
