Notify Collaborators of Task Attachments
A file gets uploaded to an Asana task, but team members miss it in the notification deluge. Notis posts a comment to the Notion page summarizing what was attached and why it matters.
Trigger
Attachment Added to Task
Triggers when an attachment is added to a task.
Action
Create comment
Adds a comment to a notion page (via `parent page id`) or to an existing discussion thread (via `discussion id`); cannot create new discussion threads on specific blocks (inline comments).
Why this helps
Files uploaded to Asana don't always bubble up in team conversations. Key resources get lost, and people re-create or re-request files because they didn't know they existed.
- Ensure team members see uploaded files
- Reduce duplicate requests for resources
- Keep file metadata and descriptions visible in Notion
- Improve team awareness without adding to notification fatigue
Setup
Build it in a few focused steps.
- 1Connect Asana and Notion to Notis in the portal.
- 2Tell Notis: 'When a file is attached to an Asana task, post a comment on the matching Notion page noting what was uploaded.'
- 3Write the prompt: 'Write a comment that says: File added: [filename] by [uploader]. Include a link to the Asana task for reference.'
- 4Select 'Attachment Added to Task' as the trigger and set your notification channel.
- 5Test by uploading a file to an Asana task and checking that a comment appears on the Notion page.
Questions about this workflow
Will this work if the Notion page doesn't exist yet?
You can set up a preliminary automation to create pages when tasks are created, then use this attachment notification automation afterward.
Can I customize the notification message?
Yes, tell Notis exactly what the comment should say. Include any metadata you want (uploader, timestamp, file size, etc.).
What if multiple files are attached at once?
Notis will post one comment per attachment, or ask it to batch them into a single comment if you prefer.

Supported Triggers and Actions
Notis builds workflows that link Asana to Notion. A trigger fires from one place; an action lands in another.

Attachment Added to Task
Triggers when an attachment is added to a task.
Add multiple content blocks (bulk, user-friendly)
Efficiently adds multiple standard content blocks to a notion page in a single api call with automatic markdown parsing. the 'content' field in notionrichtext blocks now automatically detects and parses markdown formatting including headers (# ## ###), bold (**text**), italic (*text*), strikethrough (~~text~~), inline code (`code`), links ([text](url)), and more. ideal for bulk content creation, ai agents, and replacing multiple individual add page content calls. supports automatic text formatting, content splitting, and up to 100 blocks per request.
New Comment on Task
Triggers when a comment is added to a task in a project.
Add content to Notion page
Deprecated: appends a single content block to a notion page or a parent block (must be page, toggle, to-do, bulleted/numbered list, callout, or quote); invoke repeatedly to add multiple blocks.
New Task Created
Triggers when a new task is created in a project.
Append complex blocks (advanced, full control)
Appends complex blocks with full notion block structure to a parent block or page. use for advanced scenarios requiring precise control: code blocks, tables, embeds, nested children within blocks, or when working with pre-built notion block objects. requires full notion api block schema - use add multiple page content for simpler content creation.
Task Moved to Section
Triggers when a task is moved to a section in a project.
Archive Notion Page
Archives (moves to trash) or unarchives (restores from trash) a specified notion page.
Tag Added to Task
Triggers when a tag is added to a task. Note: Asana's event structure is inverted for tag events — the resource is the task and the parent is the tag. So parent.gid gives the tag GID.
Create comment
Adds a comment to a notion page (via `parent page id`) or to an existing discussion thread (via `discussion id`); cannot create new discussion threads on specific blocks (inline comments).
Task Updated
Triggers when a task is updated in a project.
Create Notion Database
Creates a new notion database as a subpage under a specified parent page with a defined properties schema; use this action exclusively for creating new databases.
Create Notion page
Creates a new empty page in a notion workspace.
Delete a block
Archives a notion block, page, or database using its id, which sets its 'archived' property to true (like moving to "trash" in the ui) and allows it to be restored later.
