The Google User Messaging Platform (UMP) SDK is a privacy and messaging tool to
help you manage privacy choices. For more information, see

[About Privacy \& messaging](https://support.google.com/admanager/answer/10075997).


## Create a message type

Create user messages with one of the

[Available user message types](https://support.google.com/admanager/answer/10075998)

under the **Privacy \& messaging** tab of your

Ad Manager

account. The UMP SDK attempts to display a
privacy message created from the Ad Manager Application ID
set in your project.
For more details, see [About privacy and messaging](https://support.google.com/admanager/answer/10075997).

## Get the user's consent information

You should request an update of the user's consent information at every app
launch, using `Update()`. This request checks the following:

- **Whether consent is required**. For example, consent is required for the first time, or the previous consent decision expired.
- **Whether a privacy options entry point is required**. Some privacy messages require apps to allow users to modify their privacy options at any time.

```c#
void Start()
{
    // Create a ConsentRequestParameters object.
    ConsentRequestParameters requestParameters = new ConsentRequestParameters();

    // Request an update of the user's consent information.
    ConsentInformation.Update(requestParameters, OnConsentInfoUpdated);
}
```

> [!WARNING]
> **Warning:** We don't recommend that you check consent status in another way, such as the cache in your app or a previously saved consent string. These methods might return outdated user consent data.

## Load and present the privacy message form

After you have received the most up-to-date consent status, call
`LoadAndShowConsentFormIfRequired()` to load any forms required to
collect user consent. After loading, the forms present immediately.

> [!IMPORTANT]
> **Key Point:** If no privacy message forms require collection of user consent prior to requesting ads, the callback is invoked immediately.

```c#
ConsentForm.LoadAndShowConsentFormIfRequired((FormError formError) =>
{
    if (formError != null)
    {
        // Consent gathering failed.
        Debug.LogError("Error loading/showing consent form: " + formError.Message);
    }

    // ...
});
```

## Privacy options

Some privacy message forms are presented from a publisher-rendered privacy
options entry point, letting users manage their privacy options at any time.
To learn more about which message your users see at the privacy options
entry point, see

[Available user message types](https://support.google.com/admanager/answer/10075998).


### Check if a privacy options entry point is required

After you have called `Update()`, check `

PrivacyOptionsRequirementStatus` to
determine if a privacy options entry point is required for your app. If an entry
point is required, add a visible and interactable UI element to your app that
presents the privacy options form. If a privacy entry point is not required,
configure your UI element to be not visible and interactable.

```c#
void UpdatePrivacyButton()
{
    if (_privacyButton != null)
    {
        // Enable the button only if a privacy options entry point is required.
        _privacyButton.interactable =
            ConsentInformation.PrivacyOptionsRequirementStatus == PrivacyOptionsRequirementStatus.Required;
    }
}
```

For the full list of privacy options requirement statuses, see
`

ConsentInformation.PrivacyOptionsRequirementStatus`.

### Present the privacy options form

When the user interacts with your element, present the privacy options form:

```c#
public void ShowPrivacyOptionsForm()
{
    ConsentForm.ShowPrivacyOptionsForm((FormError showError) =>
    {
        if (showError != null)
        {
            Debug.LogError("Error showing privacy options form: " + showError.Message);
        }
    });
}
```

<br />

## Request ads with user consent

Before requesting ads, use `
CanRequestAds()` to check if you've
obtained consent from the user:

```c#
ConsentInformation.CanRequestAds()
```

Listed are the following places to check if you can request ads while gathering
consent:

- After the UMP SDK gathers consent in the current session.
- Immediately after you have called `Update()`. The UMP SDK might have obtained consent in the previous app session.

> [!IMPORTANT]
> **Important:** `
> CanRequestAds()` always returns `false` until you have called `Update()`

If an error occurs during the consent gathering process, check if you can
request ads. The UMP SDK uses the consent status from the previous app session.

#### Prevent redundant ad request work

As you check `
CanRequestAds()` after gathering consent and after calling
`Update()`, ensure your logic prevents redundant ad requests that
might result in both checks returning `true`. For example, with a boolean
variable.

## Testing

If you want to test the integration in your app as you're developing, follow
these steps to programmatically register your test device. Be sure to remove the
code that sets these test device IDs before you release your app.

1. Call `Update()`.
2. Check the log output for a message similar to the following example, which
   shows your device ID and how to add it as a test device:

   ### Android

       Use new ConsentDebugSettings.Builder().addTestDeviceHashedId("33BE2250B43518CCDA7DE426D04EE231")
       to set this as a debug device.

   ### iOS

       <UMP SDK>To enable debug mode for this device,
       set: UMPDebugSettings.testDeviceIdentifiers = @[2077ef9a63d2b398840261c8221a0c9b]

3. Copy your test device ID to your clipboard.

4. Modify your code to call
   `DebugGeography.TestDeviceHashedIds` and pass in
   a list of your test device IDs.

   ```c#
   void Start()
   {
       var debugSettings = new ConsentDebugSettings
       {
           TestDeviceHashedIds =
   new List\<string\>
   {
   "TEST-DEVICE-HASHED-ID"
   }
       };

       // Create a ConsentRequestParameters object.
       ConsentRequestParameters request = new ConsentRequestParameters
       {
           ConsentDebugSettings = debugSettings,
       };

       // Check the current consent information status.
       ConsentInformation.Update(request, OnConsentInfoUpdated);
   }
   ```

### Force a geography

The UMP SDK provides a way to test your app's behavior as though the device
were located in various regions, such as the European Economic Area (EEA), the
United Kingdom (UK), and Switzerland using
[`DebugGeography`](https://developers.google.com/ad-manager/mobile-ads-sdk/unity/reference/namespace/google-mobile-ads/ump/api.md.txt#debuggeography). Note that
debug settings only work on test devices.

```c#
void Start()
{
    var debugSettings = new ConsentDebugSettings
    {
        // Geography appears as in EEA for debug devices.
DebugGeography = DebugGeography.EEA,
        TestDeviceHashedIds = new List<string>
        {
            "TEST-DEVICE-HASHED-ID"
        }
    };

    // Create a ConsentRequestParameters object.
    ConsentRequestParameters request = new ConsentRequestParameters
    {
        ConsentDebugSettings = debugSettings,
    };

    // Check the current consent information status.
    ConsentInformation.Update(request, OnConsentInfoUpdated);
}
```

### Reset consent state

When testing your app with the UMP SDK, you might find it helpful to reset the
state of the SDK so that you can simulate a user's first install experience.
The SDK provides the `Reset()` method to do this.

```c#
ConsentInformation.Reset();
```

> [!CAUTION]
> **Caution:** This method is intended to be used for testing purposes only. You shouldn't call `Reset()` in production code.
