Get flows & paywalls - iOS

What getFlow retrieves
Flows BETA Built in Flow builder — renders natively on device, no WebView
Paywall Builder paywalls All existing Paywall Builder content

After you designed your flow or Paywall Builder paywall, you can display it in your mobile app. The first step is to get the flow or paywall associated with the placement and its view configuration as described below.

Want to see a real-world example of how Adapty SDK is integrated into a mobile app? Check out our sample apps, which demonstrate the full setup, including displaying paywalls, making purchases, and other basic functionality.

Before you start
  1. Create your products in the Adapty Dashboard.
  2. Create a flow/paywall and incorporate products into it in the Adapty Dashboard.
  3. Create placements and incorporate your flow/paywall into it in the Adapty Dashboard.
  4. Install Adapty SDK in your mobile app.

Fetch flow/paywall

If you’ve designed a flow or paywall using the Flow Builder or Paywall Builder, you don’t need to worry about rendering it in your mobile app code to display it to the user. Such a flow or paywall contains both what should be shown within it and how it should be shown. Nevertheless, you need to get its ID via the placement, its view configuration, and then present it in your mobile app.

To ensure optimal performance, it’s crucial to retrieve the flow or paywall and its view configuration as early as possible, allowing sufficient time for images to download before presenting them to the user.

To get a flow or paywall, use the getFlow method:

Parameters:

ParameterPresenceDescription
placementIdrequiredThe identifier of the desired Placement. This is the value you specified when creating a placement in the Adapty Dashboard.
fetchPolicydefault: .reloadRevalidatingCacheData

By default, SDK will try to load data from the server and will return cached data in case of failure. We recommend this variant because it ensures your users always get the most up-to-date data.

However, if you believe your users deal with unstable internet, consider using .returnCacheDataElseLoad to return cached data if it exists. In this scenario, users might not get the absolute latest data, but they’ll experience faster loading times, no matter how patchy their internet connection is. The cache is updated regularly, so it’s safe to use it during the session to avoid network requests.

Note that the cache remains intact upon restarting the app and is only cleared when the app is reinstalled or through manual cleanup.

Adapty SDK stores paywalls locally in two layers: regularly updated cache described above and fallback paywalls. We also use CDN to fetch paywalls faster and a stand-alone fallback server in case the CDN is unreachable. This system is designed to make sure you always get the latest version of your paywalls while ensuring reliability even in cases where internet connection is scarce.

loadTimeoutdefault: 5 sec

This value limits the timeout for this method. If the timeout is reached, cached data or local fallback will be returned.

Note that in rare cases this method can timeout slightly later than specified in loadTimeout, since the operation may consist of different requests under the hood.

Response parameters:

ParameterDescription
FlowAn AdaptyFlow object containing the placement, identifiers (id, variationId), name, remote configs, and a hasViewConfiguration flag indicating whether the flow includes a view configuration. To fetch the actual products for pre-loading, custom UI, or programmatic checks, call getPaywallProducts(flow:).

Fetch the view configuration

After fetching the flow or paywall, check whether it includes a view configuration via flow.hasViewConfiguration. The flag distinguishes how the placement was designed in the Adapty Dashboard:

  • true — the placement was designed in the Flow Builder (a flow) or the Paywall Builder (a paywall). Adapty renders the UI for you. Continue with the steps below to fetch the view configuration and present the flow or paywall.
  • false — the placement is a custom paywall with no Builder UI.

Use the getFlowConfiguration method to load the view configuration.

import AdaptyUI

guard flow.hasViewConfiguration else {
    // handle as remote config paywall
    return
}

let flowConfiguration = try await AdaptyUI.getFlowConfiguration(forFlow: flow)

Parameters:

ParameterPresenceDescription
forFlowrequiredAn AdaptyFlow object obtained via Adapty.getFlow.
locale

optional

default: nil

The identifier of the paywall localization. Expected as a language code with one or two subtags separated by - (e.g., en, pt-br). See Localizations and locale codes.
loadTimeoutdefault: 5 secThis value limits the timeout for this method. If the timeout is reached, cached data or local fallback will be returned. Note that in rare cases this method can timeout slightly later than specified in loadTimeout, since the operation may consist of different requests under the hood.
productsoptionalProvide an array of AdaptyPaywallProduct objects to optimize the display timing of products on the screen. If nil is passed, AdaptyUI will automatically fetch the necessary products.
systemRequestsHandleroptionalAn object conforming to AdaptySystemRequestsHandler that handles system permission and review requests triggered by flow actions. Required only if your flow includes such actions.
assetsResolveroptionalA [String: AdaptyCustomAsset] dictionary that overrides images and videos in the flow/paywall. See Customize assets.
timerResolveroptionalAn object conforming to AdaptyTimerResolver that supplies end dates for developer-defined timers. See Set up developer-defined timers.

Once loaded, present the flow/paywall.

Get a flow or paywall for a default audience to fetch it faster

Typically, flows and paywalls are fetched almost instantly, so you don’t need to worry about speeding up this process. However, in cases where you have numerous audiences and placements, and your users have a weak internet connection, fetching a flow or paywall may take longer than you’d like. In such situations, you might want to display a default flow or paywall to ensure a smooth user experience rather than showing nothing at all.

To address this, you can use the getFlowForDefaultAudience method, which fetches the flow or paywall of the specified placement for the All Users audience. However, it’s crucial to understand that the recommended approach is to fetch the flow or paywall by the getFlow method, as detailed in the Fetch Paywall Information section above.

Why we recommend using getFlow

The getFlowForDefaultAudience method comes with a few significant drawbacks:

  • Potential backward compatibility issues: If you need to show different paywalls for different app versions (current and future), you may face challenges. You’ll either have to design paywalls that support the current (legacy) version or accept that users with the current (legacy) version might encounter issues with non-rendered paywalls.
  • Loss of targeting: All users will see the same paywall designed for the All Users audience, which means you lose personalized targeting (including based on countries, marketing attribution or your own custom attributes).

If you’re willing to accept these drawbacks to benefit from faster flow or paywall fetching, use the getFlowForDefaultAudience method as follows. Otherwise stick to getFlow described above.

Adapty.getFlowForDefaultAudience(placementId: "YOUR_PLACEMENT_ID") { result in
    switch result {
        case let .success(flow):
            // the requested flow
        case let .failure(error):
            // handle the error
    }
}
ParameterPresenceDescription
placementIdrequiredThe identifier of the Placement. This is the value you specified when creating a placement in your Adapty Dashboard.
fetchPolicydefault: .reloadRevalidatingCacheData

By default, SDK will try to load data from the server and will return cached data in case of failure. We recommend this variant because it ensures your users always get the most up-to-date data.

However, if you believe your users deal with unstable internet, consider using .returnCacheDataElseLoad to return cached data if it exists. In this scenario, users might not get the absolute latest data, but they’ll experience faster loading times, no matter how patchy their internet connection is. The cache is updated regularly, so it’s safe to use it during the session to avoid network requests.

Note that the cache remains intact upon restarting the app and is only cleared when the app is reinstalled or through manual cleanup.

Customize assets

To customize images and videos in your paywall/flow, implement the custom assets.

Hero images and videos have predefined IDs: hero_image and hero_video. In a custom asset bundle, you target these elements by their IDs and customize their behavior.

For other images and videos, you need to set a custom ID in the Adapty dashboard.

For example, you can:

  • Show a different image or video to some users.
  • Show a local preview image while a remote main image is loading.
  • Show a preview image before running a video.
  • Provide a video’s pixel resolution so the player reserves layout space (aspect ratio = width / height) before the video loads. Pass nil to skip this.

Here’s an example of how you can provide custom assets via a simple dictionary:

let customAssets: [String: AdaptyCustomAsset] = [
    // Show a local image using a custom ID
    "custom_image": .image(
        .uiImage(value: UIImage(named: "image_name")!)
    ),

    // Show a local preview image while a remote main image is loading
    "hero_image": .image(
        .remote(
            url: URL(string: "https://example.com/image.jpg")!,
            preview: UIImage(named: "preview_image")
        )
    ),

    // Show a local video with a preview image and a known resolution
    "hero_video": .video(
        .file(
            url: Bundle.main.url(forResource: "custom_video", withExtension: "mp4")!,
            preview: .uiImage(value: UIImage(named: "video_preview")!),
            resolution: CGSize(width: 1080, height: 1920)
        )
    ),
]

let flowConfig = try await AdaptyUI.getFlowConfiguration(
    forFlow: flow,
    assetsResolver: customAssets
)

If an asset is not found, the paywall/flow will fall back to its default appearance.

Set up developer-defined timers

To use custom timers in your mobile app, create an object that follows the AdaptyTimerResolver protocol. This object defines how each custom timer should be rendered. If you prefer, you can use a [String: Date] dictionary directly, as it already conforms to this protocol. Here is an example:

@MainActor
struct AdaptyTimerResolverImpl: AdaptyTimerResolver {
    func timerEndAtDate(for timerId: String) -> Date {
        switch timerId {
        case "CUSTOM_TIMER_6H":
            Date(timeIntervalSinceNow: 3600.0 * 6.0) // 6 hours
        case "CUSTOM_TIMER_NY":
            Calendar.current.date(from: DateComponents(year: 2025, month: 1, day: 1)) ?? Date(timeIntervalSinceNow: 3600.0)
        default:
            Date(timeIntervalSinceNow: 3600.0) // 1 hour
        }
    }
}

In this example, CUSTOM_TIMER_NY and CUSTOM_TIMER_6H are the Timer IDs of developer-defined timers you set in the Adapty Dashboard. The timerResolver ensures your app dynamically updates each timer with the correct value. For example:

  • CUSTOM_TIMER_NY: The time remaining until the timer’s end, such as New Year’s Day.
  • CUSTOM_TIMER_6H: The time left in a 6-hour period that started when the user opened the paywall.

After you designed the visual part for your paywall with the Paywall Builder in the Adapty Dashboard, you can display it in your mobile app. The first step is to get the paywall associated with the placement and its view configuration as described below.

Please be aware that this topic refers to Paywall Builder-customized paywalls. If you are implementing your paywalls manually, refer to Fetch paywalls and products for remote config paywalls.

Before you start displaying paywalls in your mobile app
  1. Create your products in the Adapty Dashboard.
  2. Create a paywall and incorporate the products into it in the Adapty Dashboard.
  3. Create placements and incorporate your paywall into it in the Adapty Dashboard.
  4. Install Adapty SDK in your mobile app.

Fetch paywall designed with Paywall Builder

If you’ve designed a paywall using the Paywall Builder, you don’t need to worry about rendering it in your mobile app code to display it to the user. Such a paywall contains both what should be shown within the paywall and how it should be shown. Nevertheless, you need to get its ID via the placement, its view configuration, and then present it in your mobile app.

To ensure optimal performance, it’s crucial to retrieve the paywall and its view configuration as early as possible, allowing sufficient time for images to download before presenting them to the user.

To get a paywall, use the getPaywall method:

Parameters:

ParameterPresenceDescription
placementIdrequiredThe identifier of the desired Placement. This is the value you specified when creating a placement in the Adapty Dashboard.
locale

optional

default: en

The identifier of the paywall localization. This parameter is expected to be a language code composed of one or two subtags separated by the minus (-) character. The first subtag is for the language, the second one is for the region.

Example: en means English, pt-br represents the Brazilian Portuguese language.

See Localizations and locale codes for more information on locale codes and how we recommend using them.

fetchPolicydefault: .reloadRevalidatingCacheData

By default, SDK will try to load data from the server and will return cached data in case of failure. We recommend this variant because it ensures your users always get the most up-to-date data.

loadTimeoutdefault: 5 sec

This value limits the timeout for this method. If the timeout is reached, cached data or local fallback will be returned.

Note that in rare cases this method can timeout slightly later than specified in loadTimeout, since the operation may consist of different requests under the hood.

Response parameters:

ParameterDescription
PaywallAn AdaptyPaywall object with a list of product IDs, the paywall identifier, remote config, and several other properties.

Fetch the view configuration of paywall designed using Paywall Builder

Make sure to enable the Show on device toggle in the paywall builder. If this option isn’t turned on, the view configuration won’t be available to retrieve.

After fetching the paywall, check if it includes a view configuration, which indicates that it was created using Paywall Builder. This will guide you on how to display the paywall. If the view configuration is present, treat it as a Paywall Builder paywall; if not, handle it as a remote config paywall.

Use the getPaywallConfiguration method to load the view configuration.

import AdaptyUI

guard paywall.hasViewConfiguration else {
    //  use your custom logic
    return
}

do {
    let paywallConfiguration = try await AdaptyUI.getPaywallConfiguration(
            forPaywall: paywall,
            products: products
    )
    // use loaded configuration
} catch {
    // handle the error
}

Parameters:

ParameterPresenceDescription
paywallrequiredAn AdaptyPaywall object to obtain a controller for the desired paywall.
loadTimeoutdefault: 5 secThis value limits the timeout for this method. If the timeout is reached, cached data or local fallback will be returned. Note that in rare cases this method can timeout slightly later than specified in loadTimeout, since the operation may consist of different requests under the hood.
productsoptionalProvide an array of AdaptyPaywallProduct objects to optimize the display timing of products on the screen. If nil is passed, AdaptyUI will automatically fetch the necessary products.

            // the requested paywall
        case let .failure(error):
            // handle the error
    }
}

The getPaywallForDefaultAudience method is available starting from iOS SDK version 2.11.2.

ParameterPresenceDescription

Note that the cache remains intact upon restarting the app and is only cleared when the app is reinstalled or through manual cleanup.

Customize assets

To customize images and videos in your paywall, implement the custom assets.

Hero images and videos have predefined IDs: hero_image and hero_video. In a custom asset bundle, you target these elements by their IDs and customize their behavior.

For other images and videos, you need to set a custom ID in the Adapty dashboard.

For example, you can:

  • Show a different image or video to some users.
  • Show a local preview image while a remote main image is loading.
  • Show a preview image before running a video.

To use this feature, update the Adapty iOS SDK to version 3.7.0 or higher.

Here’s an example of how you can provide custom assets via a simple dictionary:

let customAssets: [String: AdaptyCustomAsset] = [
    // Show a local image using a custom ID
    "custom_image": .image(
        .uiImage(value: UIImage(named: "image_name")!)
    ),

    // Show a local preview image while a remote main image is loading
    "hero_image": .image(
        .remote(
            url: URL(string: "https://example.com/image.jpg")!,
            preview: UIImage(named: "preview_image")
        )
    ),

    // Show a local video with a preview image
    "hero_video": .video(
        .file(
            url: Bundle.main.url(forResource: "custom_video", withExtension: "mp4")!,
            preview: .uiImage(value: UIImage(named: "video_preview")!)
        )
    ),
]

let paywallConfig = try await AdaptyUI.getPaywallConfiguration(
    forPaywall: paywall,
    assetsResolver: customAssets
)

If an asset is not found, the paywall will fall back to its default appearance.

Set up developer-defined timers

To use custom timers in your mobile app, create an object that follows the AdaptyTimerResolver protocol. This object defines how each custom timer should be rendered. If you prefer, you can use a [String: Date] dictionary directly, as it already conforms to this protocol. Here is an example:

@MainActor
struct AdaptyTimerResolverImpl: AdaptyTimerResolver {
    func timerEndAtDate(for timerId: String) -> Date {
        switch timerId {
        case "CUSTOM_TIMER_6H":
            Date(timeIntervalSinceNow: 3600.0 * 6.0) // 6 hours
        case "CUSTOM_TIMER_NY":
            Calendar.current.date(from: DateComponents(year: 2025, month: 1, day: 1)) ?? Date(timeIntervalSinceNow: 3600.0)
        default:
            Date(timeIntervalSinceNow: 3600.0) // 1 hour
        }
    }
}

In this example, CUSTOM_TIMER_NY and CUSTOM_TIMER_6H are the Timer IDs of developer-defined timers you set in the Adapty Dashboard. The timerResolver ensures your app dynamically updates each timer with the correct value. For example:

  • CUSTOM_TIMER_NY: The time remaining until the timer’s end, such as New Year’s Day.
  • CUSTOM_TIMER_6H: The time left in a 6-hour period that started when the user opened the paywall.
