What are Placements?

A Placement is a UI component that can be embedded directly in your app. Think of it as a designated space where referral interfaces, rewards notifications, or promotional content can appear at strategic moments in the user journey. Placements are:
  • Dynamic: They can be shown or hidden based on user actions
  • Flexible: They can be placed anywhere in your app’s UI
  • Controlled: Marketers can activate or deactivate them without code changes

​
How Checkpoints Trigger Placements

Checkpoints and Placements work together to create a powerful, context-aware user experience:
  1. Checkpoints mark specific moments in the user journey (e.g., completing a purchase, reaching a milestone)
  2. Placements define the UI components appear in your app
  3. Campaigns connect checkpoints to placements through the Flock dashboard
When a user hits a checkpoint in your app, the Flock system checks if the active campaign is configured to show a placement at that checkpoint. If there is, the appropriate UI component appears instantly.
By default, calling a checkpoint won’t trigger any UI changes. You need to link checkpoints to placements through Flock Campaign builder.

​
Implementation

​
Step 1: Implement Checkpoints in Your App

First, add checkpoints at strategic moments in your user journey using the Flock SDK: 
// After user completes a key action (e.g., purchase)
Flock.shared.checkpoint(
  name: "purchase_completed"
).trigger()
Once you’ve implemented checkpoints in your app, you can link them to placements through the Flock Campaign Builder: Campaign Builder Screenshot

​
Step 3: Test Your Implementation

To ensure your checkpoints are correctly triggering placements:
  1. Use your Test environment: Always make sure to use your Test environment to verify your setup.
  2. Trigger Checkpoints: Perform the actions in your app that should trigger checkpoints.
  3. Verify Placements: Confirm that the correct placements appear at the right moments.

Advanced Configuration

​
Handling Placement Navigation

When a placement is displayed, you can navigate to different screens within the same modal without closing and reopening it. This provides a seamless user experience, especially for multi-step flows like referral processes. 
Flock.shared.checkpoint("purchase_completed")
  .onSuccess { flock in
    // Navigate to a success screen within the current modal
    flock.checkpoint("referral_succeeded").navigate().trigger()
  }
  .trigger()
The navigate() method is key here - it tells the SDK to navigate within the existing web view instead of creating a new placement. This is particularly useful for:
  • Showing success screens after a user completes an action
  • Creating multi-step referral flows
  • Displaying additional information without disrupting the user experience
When using navigate(), make sure the destination checkpoint is properly configured in your Flock campaign. The navigation will only work if the checkpoint exists and has content assigned to it.

​
Troubleshooting

If placements aren’t appearing when checkpoints are triggered:
  1. Check SDK Implementation: Ensure you’re correctly calling the checkpoint method
  2. Verify Campaign Configuration: Confirm that the checkpoint is linked to a placement in an active campaign
  3. Test Mode: Make sure you’re testing in the correct environment (test vs. production)
  4. SDK Initialization: Verify that the Flock SDK is properly initialized and the user is identified
  5. Console Logs: Check your application logs for any SDK errors or warnings
