Get Started with HAP

---

This article helps you quickly get started with HAP by building a simple recruitment management app.

1. Introduction to HAP

HAP (Hyper Application Platform) is a no code platform for building enterprise applications. It enables teams to create applications for scenarios such as sales, operations, HR, and procurement, while centralizing data across the organization.

HAP includes a built-in automation engine for handling complex and repetitive processes. With its integration center and API capabilities, it can connect with external systems. It also supports internationalization and cloud-native deployment, including multi-cloud environments.

Applications built in HAP are referred to as apps, ranging from simple ticketing systems to complex enterprise systems such as ERP.

HAP applications are built using the following core modules:

• Worksheet – Stores business data such as customers, orders, or inventory.
• View – Displays data in different formats based on use cases.
• Roles and Permissions – Controls who can view or modify data.
• Workflow – Automates data processing and business processes.
• ChatBot – Enables users to interact with data, workflows, and external systems through conversations.
• Chart – Provides data analysis for reporting and decision-making.
• Custom Page – Builds dashboards or workspaces with charts and actions.
• External Portal – Allows external users to access and interact with the app.

The following example demonstrates how to build a simple app.

2. Application Planning

Before building your application, define the following:

• Business processes and automation requirements
• All related business data
• Roles involved and their permissions

In this example, we will build a recruitment management app.

1. Business Process

A typical recruitment process includes:

• Collect candidate resumes
• Manage candidate information
• Schedule interviews
• Notify interviewers before interviews (automated)
• Update interview results
• Sync hiring results to candidate records (automated)
• Monitor candidate status through a dashboard

2. Business Data

The main data in this app includes:

• Candidate information (resumes)
• Interview scheduling data

3. Roles

The app includes the following roles:

• Candidate
• HR
• Department Manager

4. How HAP Supports These Requirements

Requirement	HAP Solution
Candidates submit resumes	Create a Candidate worksheet to store resume data
Manage candidate information	Create views for different statuses
Schedule interviews	Create an Interview Schedule worksheet
Notify interviewers before interviews	Create a workflow triggered by interview time
Update interview results	Create a role with edit permissions
Sync hiring results to candidate records	Use a workflow to update related records
Monitor candidate status	Create a custom page with charts

3. Build the Application

1. Create an App

Create a new app named Recruitment Management. All worksheets and data for this solution will be managed within this app.

You can now use worksheets, views, roles and permissions, charts, custom pages, and workflows to build your recruitment management app.

2. Create Worksheets

A worksheet is the core component of an app. It is used to store and manage business data.

Each worksheet represents a business object (such as candidates or interviews), while fields define the attributes of those objects (such as name, phone number, or position).

For this example, create the following worksheets:

• Candidate
• Interview Schedule

2.1 Create the Candidate Worksheet

Candidate data is typically managed with fields such as name, date of birth, phone number, email, and applied position.

Create a worksheet to manage this data:

After clicking Create Worksheet, the system opens the worksheet design canvas.

Drag fields from the left panel into the canvas and configure properties such as name, width, and required status.

Field	Control Type
Name	Text
Email	Email
Phone	Phone
Date of Birth	Date
Applied Position	Single Select
Applicaation Source	Single Select
Status	Single Select
Resume	File

Completed worksheet:

1) Add Records

Records can be created manually or imported from Excel.

Download sample file

After importing data:

2) Manage Records

Click a record to open its detail page. From there, you can edit, share, comment, print, or delete the record.

3) Bulk Actions

4) Publish as a Public Form

To collect candidate data externally, publish the worksheet as a public form:

Edit Form > Extend > Enable Public Form

Customize the form (logo, background, description, and visible fields), then share it via link or QR code.

Users can submit data without logging in:

5) Additional Features

• Business Rules: Show, hide, or lock fields based on conditions
• Custom Actions: Add buttons to trigger contextual actions
• Print Templates: Design templates in Word and print records accordingly

2.2 Create the Interview Schedule Worksheet

The interview schedule typically includes the following fields:

• Candidate
• Applied Position
• Resume
• Interviewer
• Start Time
• End Time
• Comments
• Result

Example design:

Fields like Comments and Result are not needed during creation, so set them to hidden on create.

2.3 Link Worksheets

Use a relationship field to link Candidate and Interview Schedule worksheets and avoid duplicate data entry.

1) Add a Relationship Field

In the Interview Schedule worksheet, add a relationship field linked to the Candidate worksheet.

2) Configure the Relationship

Each interview is associated with one candidate → select Single record.

Each candidate can have multiple interviews → configure Multiple records on the Candidate side (enable bidirectional relationship).

Remove the original text field for candidate name. Now you can directly select candidates when creating interview records:

3) Use Foreign Fields

Use foreign fields to display related data such as gender, position, and resume.

Configuration:

• Field name: Applied Position
• Relationship field: Candidate
• Display field: Applied Position
• Type:
  • Display only (for real-time display)
  • Data storage (for filtering, sorting, and calculations)

Repeat for Resume (Display only) field.

4) Set the Title Field

The title field uniquely identifies each record.

For better readability, use a concat field to combine key attributes (e.g., Name + Position), and set it as the title field.

Final structure:

Field	Control Type	Notes
Title	Concat field	Name - Position
Candidate	Relationship field	Single record
Applied Position	Foreign field	Data storage
Interviewer	Member
Start Time	Date
End Time	Date
Resume	Foreign field	Display only
Comments	Text
Result	Single Select

Final form:

3. Work with Views

A view defines how data is displayed and interacted with in a worksheet, including layout, visible fields, filters, and sorting.

Supported view types include:

• Table view
• Kanban view
• Org view
• Gallery view
• Calendar view
• Gantt view
• Map view
• Resources view
• Details view
• Custom view

Each worksheet includes a default Table view named “All”, which displays all records.

Views are commonly used to:

• Segment records by status or conditions
• Present data in different formats
• Limit visibility based on user roles

3.1 Manage Candidates by Status

1) Create Table Views by Status

Create multiple table view views to segment candidates by status.

Example: New Resumes view

• Filter: Status = New Resume
• Sort: Created Time

Result:

Repeat this configuration to create views for other statuses:

2) Use Kanban View

Use Kanban view to group records by status.

All records are displayed and grouped by status:

3.2 Use Calendar View for Interview Scheduling

Create a Calendar view in the Interview Schedule worksheet.

• Start time: Interview Start Time
• End time: Interview End Time

Apply a filter to show only relevant records:

• Interviewer = Current User

4. Roles and Permissions

Roles control how users access and interact with data in an app.

Role types:

• App Admin
  Full access to configure the app, including structure, features, and permissions. This role cannot be modified.

• Custom Roles
  Used to define data access and actions for users.

In this example:

• Candidates submit data via a public form (no role required)
• HR acts as App Admin
• Department managers are assigned a custom role

4.1 Invite Users

Invite users via email or phone number.

4.2 Configure Roles and Permissions

1) Configure Role for Department Managers

Each app includes default roles such as Member and Read-only. These can be modified or duplicated.

Configure permissions as shown:

Key settings:

• Step 5: Grant access to the My Interviews view
• Step 6: Allow editing of records within that view

Users will not have access to:

• Views in the Candidate worksheet
• The “All” view in the Interview Schedule worksheet

2) Assign Users to Role

Add specific users (e.g., department managers) to the role.

3) Role Access

Users can only access records in the My Interviews* view:

4) Update Interview Results

To update interview results:

1. Open the interview record
2. Edit the Comments and Result fields
3. Save changes

Permissions can be configured at both the record level and field level.

5. Use Workflows

A workflow consists of a trigger and one or more automation nodes.

When the trigger condition is met, the workflow executes the configured actions automatically.

Workflows are used to automate repetitive operations and streamline business processes.

The following automation scenarios are implemented:

• Notify interviewers 15 minutes before the interview starts
• Sync interview results to the Candidate worksheet

5.1 Notify Interviewers Before Interview Start

1) Select Trigger Type

Supported trigger types:

• Worksheet event trigger
  Triggered by record create, update, or delete events

• Scheduled trigger
  Triggered at a specified time

• Date field trigger
  Triggered based on a date field in a worksheet

• Webhook trigger
  Triggered by external system requests

• Button trigger
  Triggered manually by clicking a button

For this scenario, select a Date field trigger.

2) Configure Trigger

• Worksheet: Interview Schedule
• Date field: Interview Start Time
• Trigger time: 15 minutes before the start time

3) Add CC Node

Add a CC node to deliver reminders.

• Message content: Use field values or static text
• Recipients: Select the Interviewer field

4) Publish Workflow

5) Notification Result

• Mobile:

  

• Desktop:

  

5.2 Sync Interview Results to Candidate Records

The Interview Schedule worksheet includes a Result field (e.g., Passed, Rejected, Pending).
The Candidate worksheet includes a Status field.

When the interview result is updated, the candidate status should be updated automatically:

• Passed → Background Check
• Rejected → Rejected
• Pending → No update

1) Create Workflow

Select Worksheet event trigger.

2) Configure Trigger

• Worksheet: Interview Schedule
• Trigger condition: Result field is updated

3) Add Branch Node

Add a branch node to handle different outcomes based on the interview result.

4) Add Get Single Data Node

Use the Get Single Data node to retrieve the related candidate record.

• Method: Get from relationship field
• Source: Candidate relationship field

5) Add Update Record Node

Update the candidate’s status:

• Target record: Retrieved candidate record
• Field: Status → Background Check

6) Complete Branch Logic

Configure additional branches for other outcomes (e.g., Rejected).

7) Publish Workflow

8) Test Workflow

1. Open an interview record
2. Update the Result field
3. Save the record

The related candidate record is updated automatically.

Workflows can be extended to support more complex automation scenarios. Refer to the Help Center for additional nodes and use cases.

6. Charts

Charts help you analyze business data by visualizing metrics, identifying trends, and supporting decision-making.

In this recruitment management app, common scenarios include:

• Tracking candidates awaiting interviews this week
• Monitoring hired candidates
• Analyzing candidate status distribution

1) Create a Chart

To analyze interview-related data, create charts under the Interview Schedule worksheet.

2) Configure the Chart

Chart configuration typically includes:

1. Define the data scope
2. Select a chart type
3. Choose dimensions and metrics
4. Set the chart name
5. Save the chart
