Update a task

Connector functions are a new addition to Slack automations. We recommend understanding the systems and APIs you're integrating with before setup.

Authentication

A connector's access token property specifies how the connector handles authentication.

End-user authentication

user Workflows that include a connector function relying on end-user authentication can can only be started with a link trigger.

asana_access_token: {
    credential_source: "END_USER"
}

End-user experience: User will be prompted to link their external account via OAuth when they first start the workflow that contains this connector.

Developer experience: Developer does not have to implement authentication in app.

Developer authentication 

asana_access_token: {
    credential_source: "DEVELOPER"
}

End-user experience: User can start a workflow containing the connector (they are not prompted to authenticate).

Developer experience: One of the app's collaborators configures external authentication via the CLI before sharing the app with users.

How to use

First, import Connectors from deno-slack-hub into your project's import_map.json file, like this:

{
  "imports": {
    "deno-slack-hub/": "https://deno.land/x/deno_slack_hub@2.2.0/",
    "deno-slack-sdk/": "https://deno.land/x/deno_slack_sdk@2.14.2/",
    "deno-slack-api/": "https://deno.land/x/deno_slack_api@2.8.0/",
  }
}

Next, import Connectors at the top of your workflow's definition file:

// my_workflow_file.ts
import { Connectors } from "deno-slack-hub/mod.ts";

Finally, add the connector as a step in your workflow just like you would a built-in Slack function.

SomeWorkflow.addStep(
  Connectors.Asana.functions.UpdateTask, {
    // The globally unique identifier for the workspace or organization
    workspace_gid: "0fb0abc-1qwe234-asdf1234-zxcv0987",

    // The globally unique identifier for the task to update
    task_gid: "02af8431-baa5-42d5-86ee-4fa270c5ef32",

    // (Optional) the Slack user ID of the person to assign this task to
    // assignee: "U123456",

    // (Optional) A concise name for this task
    // name: "Merge orders spreadsheets",

    // (Optional) The date and time when this task should start, as a Unix timestamp
    // start_at: 1698681600,

    // (Optional) The date and time when this task is due, as a Unix timestamp
    // due_at: 1710220715,

    // (Optional) Free-form text describing this task
    // description: "Merge these orders spreadsheets and make sure to alert billing if we are off by 10%",

    // (Optional) Whether this task should be marked as already complete
    // completed: true,

    asana_access_token: { credential_source: "END_USER" }
  }
);

🧙🏼 Your admin may need to approve the connector first. If your workspace has been configured to only allow admin-approved apps, the CLI will prompt you to send an admin approval request the first time you try to use a connector that hasn't been approved by an admin yet. While waiting for admin approval, the CLI may report an error like this:

Workflow function... is referring to an unknown step output parameter...

You can safely ignore this error; it will go away as soon as your workspace admin approves your request to use the connector.
