## Overview

In the Walkthrough Checklist, whenever a Sub-Flow is completed, there is a check mark to show that the Sub-Flow is completed. If there is a requirement to auto start a Sub-Flow and achieve the same behavior as that of a Checklist, the Sub-Flow needs to be started by its project ID prefixed with its checklist project ID.

Use the following steps to auto start a Sub-Flow in a Walkthrough Checklist:

Info:

- If the Sub-Flow is started only with its project ID, it is considered as an independent Project and not part of the Checklist.
- For more information about generating a project ID, see [Publish using Project ID](/mobile/docs/publish-using-project-id).

## Step 1: Generate the project ID of the Checklist project

![checklist_project_id](https://cdn.document360.io/a268766e-d74d-4619-9613-e2472f809ffb/Images/Documentation/checklist_project_id.gif?sv=2026-02-06&spr=https&st=2026-10-29T18%3A57%3A58Z&se=2026-10-29T19%3A57%3A58Z&sr=c&sp=r&sig=89GOnJqxcyjDqArgWC7I%2BHXCxQKTBSzWZ1wDXMlPc%2BE%3D)

## Step 2: Generate the project ID of the Sub-Flow project

![sub_flow_project_id](https://cdn.document360.io/a268766e-d74d-4619-9613-e2472f809ffb/Images/Documentation/sub_flow_project_id.gif?sv=2026-02-06&spr=https&st=2026-10-29T18%3A57%3A58Z&se=2026-10-29T19%3A57%3A58Z&sr=c&sp=r&sig=89GOnJqxcyjDqArgWC7I%2BHXCxQKTBSzWZ1wDXMlPc%2BE%3D)

## Step 3: Generate a new project ID combining the Checklist and the Sub-Flow project IDs

Combine the Checklist project ID and the Sub-Flow project ID separated by **#**.

For example, if the Checklist project ID is **87b73d04-da5d-4ea6-8b71-8fed700157bb** and the Sub-Flow’s project ID is **33c6abcc-a077-4cae-9c45-33a6c730fba4**. The new project ID is the combination of the Checklist project ID and the Sub-Flow project ID separated by #, i.e., **87b73d04-da5d-4ea6-8b71-8fed700157bb#33c6abcc-a077-4cae-9c45-33a6c730fba4.**

  

## Step 4: Start the Sub-Flow

Use the following code snippets to start the Sub-Flow:

Android

## Android

```javascript
Leap.embedProject("<CHECKLIST_PROJECT_ID>#<SUBFLOW_PROJECT_ID>");

// e.g - Leap.embedProject("87b73d04-da5d-4ea6-8b71-8fed700157bb#33c6abcc-a077-4cae-9c45-33a6c730fba4");
```

iOS Swift

## iOS Swift

```javascript
Leap.shared.embedProject("<CHECKLIST_PROJECT_ID>#<SUBFLOW_PROJECT_ID>");

// e.g - Leap.shared.embedProject("87b73d04-da5d-4ea6-8b71-8fed700157bb#33c6abcc-a077-4cae-9c45-33a6c730fba4");
```

iOS Objective-C

## iOS Objective-C

```javascript
[[Leap shared] embedProject:@"<CHECKLIST_PROJECT_ID>#<SUBFLOW_PROJECT_ID>"];

// e.g - [[Leap shared] embedProject:@"87b73d04-da5d-4ea6-8b71-8fed700157bb#33c6abcc-a077-4cae-9c45-33a6c730fba4"];
```

ReactNative

## ReactNative

```javascript
LeapReactNative.embedProject("<CHECKLIST_PROJECT_ID>#<SUBFLOW_PROJECT_ID>");
```

Ionic

## Ionic

```javascript
LeapPlugin.startProject({projectId:"<CHECKLIST_PROJECT_ID>#<SUBFLOW_PROJECT_ID>"});
```

Cordova (Android)

## Cordova (Android)

```javascript
cordova.plugins.LeapAndroid.embedProject("<CHECKLIST_PROJECT_ID>#<SUBFLOW_PROJECT_ID>");

// e.g - cordova.plugins.LeapAndroid.embedProject("87b73d04-da5d-4ea6-8b71-8fed700157bb#33c6abcc-a077-4cae-9c45-33a6c730fba4");
```

Cordova (iOS)

## Cordova (iOS)

```javascript
cordova.plugins.LeapiOS.embedProject("<CHECKLIST_PROJECT_ID>#<SUBFLOW_PROJECT_ID>");

// e.g - cordova.plugins.LeapiOS.embedProject("87b73d04-da5d-4ea6-8b71-8fed700157bb#33c6abcc-a077-4cae-9c45-33a6c730fba4");
```

Xamarin Android

## Xamarin Android

```javascript
Leap.EmbedProject("<CHECKLIST_PROJECT_ID>#<SUBFLOW_PROJECT_ID>");

// e.g - Leap.EmbedProject("87b73d04-da5d-4ea6-8b71-8fed700157bb#33c6abcc-a077-4cae-9c45-33a6c730fba4");
```

Xamarin iOS

## Xamarin iOS

```javascript
Leap.Shared.EmbedProject("<CHECKLIST_PROJECT_ID>#<SUBFLOW_PROJECT_ID>");

// e.g - Leap.Shared.EmbedProject("87b73d04-da5d-4ea6-8b71-8fed700157bb#33c6abcc-a077-4cae-9c45-33a6c730fba4");
```

Info:

The Sub-Flow can also be launched from a notification. For more information see, [Launch via Notification](/mobile/docs/launch-via-notification). Use Step 3 to generate the new project ID, which is a combination of Checklist and Sub-Flow project IDs.
