Create APIs that trigger workflows and other processes

# Trigger APIs

## Overview

You can create APIs to initiate workflows, data processing jobs, or other automated processes.

## Basic Usage

```typescript filename="app/apis/trigger_workflow.ts" copy

interface WorkflowParams {
  inputValue: string;
  priority?: string;
}

interface WorkflowResponse {
  workflowId: string;
  status: string;
}

const triggerApi = new Api<WorkflowParams, WorkflowResponse>(
  "trigger-workflow",
  async ({ inputValue, priority = "normal" }: WorkflowParams, { client }) => {
    // Trigger the workflow with input parameters
    const workflowExecution = await client.workflow.execute("data-processing", { 
        inputValue,
        priority,
        triggeredAt: new Date().toISOString()
      }
    );

    return {
      workflowId: workflowExecution.id,
      status: "started"
    };
  }
);
```

## Using the Trigger API

Once deployed, you can trigger workflows via HTTP requests:

```bash filename="Terminal" copy
curl "http://localhost:4000/api/trigger-workflow?inputValue=process-user-data&priority=high"
```

Response:
```json
{
  "workflowId": "workflow-12345",
  "status": "started"
}
```
