Asana to Notion Workflow with n8n

Here's a step-by-step process to build your Asana to Notion workflow with n8n.io:

1. Setting Up n8n.io:

use n8n their cloud service (details on their website).

Familiarize yourself with the n8n interface. It uses a node-based system to build workflows.

Start Node: Add an "On Update Asana" node as the trigger. This will initiate the workflow whenever a task is updated in Asana.

Connect Asana Account: Configure the Asana node with your API key and Workspace ID.

Extract Task Details: Add a "Code" node after the Asana node. Here, write JavaScript code to extract relevant task details like name, description, due date, etc., from the Asana data received by the previous node.

```javascript const gids = [];

// get all the unique Asana task gids for (item of items) { var gid = parseInt(item.json.resource.gid); var resource_type = item.json.resource.resource_type; if (!(gids.includes(gid)) && resource_type == "task") { gids.push(gid); } }

// show in output const new_items = []; for (gid of gids) { var new_item = { "json": { "gid": 0, "gids": [], "notionfilter": "" } }; new_item = JSON.stringify(new_item); new_item = JSON.parse(new_item); new_item.json.gid = gid; new_item.json.gids = gids; new_items.push(new_item);

// Notion filter notionfilter = { or: [], }

for (gid of gids) { const filter = { property: 'Asana GID', number: { equals: gid } } notionfilter["or"].push(filter); }

new_item.json.notionfilter = JSON.stringify(notionfilter); }

console.log(gids); return new_items;

Conditional Branching: Add a "Conditional" node. Connect the previous code node's output to this. Based on the "new" or "update" flag set in the code, the workflow will branch into separate paths.

If the task is new, connect the "Conditional" node's "new" output to a "Notion Create Page" node. Configure this node to create a new page in your Notion "Tasks" database using the extracted task details from the first code node.

If the task is an update, connect the "Conditional" node's "update" output to a "Notion Update Page" node. Configure this node to update the existing Notion page (matching the Asana task ID or another identifier) with the latest details from the first code node.

Save and test your workflow thoroughly with sample Asana tasks.

Once satisfied, deploy your workflow in n8n.io. This will ensure it runs automatically whenever a task is updated in Asana.
