Within your Workstation App you can create tasks and review their output to check if the answers are correct.

​
Creating tasks via API

Creating a new task is similar to making a call to your Canvas, except that instead of passing your canvas_id, you’re going to pass your application_id. Head to your Workstation App page and follow these steps:
1

Open Connect via API

At the top bar, click on the three dots on the right of your app’s title and select “Connect via API”.Connect via API
2

Get your app data

Here you will find all the necessary info to start creating tasks with our API. Choose your preferred language and use one of the snippets provided to get started!Connect modal
By default, all tasks are created as if they were async completions. You’ll receive a success response and the task will have a running status. You have two options for consuming the result of the task:
  • Polling during execution
  • Passing a webhook URL

​
Polling tasks during execution

You can do a simple polling until the status of the task changes to either completed or failed. To poll the status of a task after creating it we can make a request to our API /task endpoint. 
let task = await tela.completions.create<{ document: TelaFile }, { fileSummary: string }>({
    applicationId: process.env.TELA_APPLICATION_ID,
    variables: {
        document: tela.createFile('https://example.com/document.pdf')
    },
})

let isTaskCompleted = false

while (!isTaskCompleted) {
    const response = await fetch(`https://api.tela.com/task/${task.id}`)
    task = await response.json()
    isTaskCompleted = task.status === 'completed' || task.status === 'failed'
}

​
Passing a webhook URL

You can pass a webhook_url to your API call. This way you’ll receive a POST request in your endpoint when the task finishes. 
const task = await tela.completions.create<{ document: TelaFile }, { fileSummary: string }>({
    applicationId: process.env.TELA_APPLICATION_ID,
    variables: {
        document: tela.createFile('https://example.com/document.pdf')
    },
    webhook_url: "https://example.com/webhook"
})

​
Fetching tasks

To retrieve tasks from an app, you can send a GET request to the /task endpoint. This endpoint supports various optional parameters for filtering and pagination:

​
Pagination parameters

  • limit: Number of results per response (default: 10, range: 1-100)
  • offset: Starting position of results (default: 0)

​
Filtering parameters

  • status: Array of task statuses (options: “created”, “running”, “validating”, “completed”, “failed”)
  • since: Start date for filtering tasks (format: timestamp or ISO 8601)
  • until: End date for filtering tasks (format: timestamp or ISO 8601)
  • approvedBy: Email of the user who approved the task
  • revisionProcess: Type of revision received (options: “approvedWithRevisions”, “approvedDirectly”)
  • promptApplicationId: ID of the application where the task was created
  • promptVersionId: ID of the Canvas version used to create the task
  • ids: Array of specific task IDs to retrieve

​
Sorting parameters

  • orderBy: Field to sort by (options: “name”, “reference”, “approvedAt”, “createdAt”, “updatedAt”, “id”, “status”, “approvedBy”, “createdBy”)
  • order: Sort direction (options: “asc” or “desc”)

​
Example request

Here’s an example of fetching 50 completed tasks created after November 1st, 2024, sorted by name in ascending order: 
const url = new URL('https://api.tela.com/task')
url.searchParams.append('limit', '50')
url.searchParams.append('promptApplicationId', '{YOUR_APPLICATION_ID}')
url.searchParams.append('status', JSON.stringify(['completed']))
url.searchParams.append('since', '2024-11-01T00:00:00Z')
url.searchParams.append('orderBy', 'name')
url.searchParams.append('order', 'asc')

const response = await fetch(url, {
    method: 'GET',
    headers: {
        'Authorization': `Bearer ${process.env.TELA_API_KEY}`,
        'Content-Type': 'application/json',
    },
});

const tasks = await response.json()
