Self Assessment SDK Implementation

This guide provides everything you need to integrate the Self Assessment SDK into your application.

​
Overview

The Self Assessment SDK allows you to integrate intelligent assessment workflows into your healthcare applications. It provides:

  • Interactive Assessments: Run dynamic, workflow-based patient assessments
  • Flexible Workflows: Support for multiple assessment workflows and categories

​
Installation

​
Prerequisites

  • A modern web browser
  • A web server or development environment
  • Valid authentication tokens from your Self Assessment provider

​
Setup

Add the SDK script directly to your HTML:

<!DOCTYPE html>
<html>
  <head>
    <title>Self Assessment Integration</title>
  </head>
  <body>
    <!-- Container for the Self Assessment app -->
    <div id="sa-container"></div>

    <!-- Include the Self Assessment SDK -->
    <script src="https://api.eka.care/sa-fe/main.js"></script>

    <script>
      // Your integration code will go here
    </script>
  </body>
</html>

​
Core Functions

​
1. runSaApp

Initializes and runs a Self Assessment application.

Parameters:

  • workflow_id (number, required): The ID of the assessment workflow to run
  • container_id (string, required): The HTML element ID where the assessment will be rendered
  • auth_token (string, required): JWT authentication token for API access
  • refresh_token (string, required): Token used to refresh the auth token when it expires

Example:

window.runSaApp({
  workflow_id: 4014,
  container_id: "sa-container",
  auth_token: "your-jwt-token",
  refresh_token: "your-refresh-token",

Error Handling

All functions return consistent error objects with:

  • error_code: Machine-readable error code
  • display_message: User-friendly error message
  • message: Technical error details

Common Error Codes:

  • AUTH_ERROR: Authentication failed
  • NETWORK_ERROR: Network connection issues
  • FETCH_ERROR: Data fetching failed
  • VALIDATION_ERROR: Invalid parameters
  • UNKNOWN_ERROR: Unexpected errors

​
Troubleshooting

​
Common Issues

​
1. Container Not Found

Problem: Assessment doesn’t appear in the container.

Solution:

  • Ensure the container element exists before calling runSaApp
  • Check that container_id matches the actual HTML element ID
  • Make sure the container has proper dimensions
<div
  id="sa-container"
  style="width: 100%; height: 600px; border: 1px solid #ccc;"
></div>

​
2. Authentication Errors

Problem: Assessment fails to initialize due to auth issues.

Solution:

  • Verify your auth_token and refresh_token are valid
  • Check that tokens haven’t expired
  • Ensure you’re using the correct authentication flow for Self Assessment

​
3. Workflow Not Found

Problem: Assessment fails with workflow-related errors.

Solution:

  • Verify the workflow_id exists and is accessible
  • Use getWorkflowList() to see available workflows
  • Check if the workflow requires specific parameters
// Check available workflows
window.getWorkflowList().then((response) => {
  console.log("Available workflows:", response.workflows);
});
