API Summary
CIM is a service that adds AI logic to your web app, without actually modifying its source code. This makes your web app context-aware and therefore provide a better experience to your customers.
How does it work:
- The CIM service interacts with an app and workflow (defined by the Workflow Designer toolkit).
- The workflow must specify:
- The AI engine to be used.
- The condition, and the action to be performed when that condition is satisfied.
- Whether the app and workflow need to share data.
- If yes, then the workflow must include the 'data-inject' and/or 'data-publish' nodes.
- The app must correspondingly invoke the 'injectDataToWorkflow' and/or 'getDataFromWorkflow' methods.
- The workflow is packaged with the app.
- The packaged app is then deployed on the device.
Before using the Service
Add necessary permissions (cim.release) in the appinfo.json file (see below)
- "requiredPermissions":["cim.release"]

injectDataToWorkflow
Description
Injects data from the app to the workflow.
Parameters
Name | Required | Type | Description |

| key | Required | String | Identifies the 'data-inject' node that is defined in the workflow. Note: Make sure that the key is associated with the relevant 'data-inject' node. |
| data | Required | String | The actual data that must be sent to the workflow. It must be a stringified object. |
Call Returns
Name | Required | Type | Description |
|---|---|---|---|
| returnValue | Required | Boolean | Indicates the status of operation. Possible values are:

Example
Example scenario
// This API must be called within an app. Below is a sample app code snippet. Do not try to run the code directly from the terminal as it will fail.
function injectDataToWorkflow(){
var bridge = new WebOSServiceBridge();
var url = 'luna://com.webos.service.contextintentmgr/injectDataToWorkflow';
bridge.onservicecallback = callback;
function callback(msg){
var response = JSON.parse(msg);
console.log(response.returnValue);
}
var params = '{
key: "6bb6c4ab.00e67c_128e776f.c57939", // Key generated in the data-inject node
data: <>
}';
bridge.call(url, params);
}
