Quick overview

Fetch your eight personal invoices and twelve payments for Community Weekly Challenge 09, The Balance Check. One HTTP request feeds two connected Split Out lanes. Build your own native balance calculation using the instructions and permanent challenge links.

How it works

  1. Start here runs the workflow manually. Importing the file and reading the instructions do not start your timer.
  2. Your account holds two empty Edit Fields values: username and participantKey. Missing setup stops locally before the HTTP request.
  3. Fetch invoices and payments sends one GET to the permanent C09 endpoint. The first personal data issuance starts your clock; re-fetching preserves the assignment and original start.
  4. Split invoices emits one item per invoice from assignment.invoices. Continue with your own native nodes to select active invoices and calculate their balances.
  5. Split payments emits one item per payment from assignment.payments. Match posted payments by exact invoice_id. The starter contains no sample packet or completed calculation.

Setup

  1. Read the challenge and full FAQ at https://marketing.app.n8n.cloud/webhook/cwc/site before executing. Create your community challenge account or recover your current participant key using that website.
  2. Enter your community username without @ and your current participant key in Your account. Leave HTTP authentication set to None. Before C09 opens, the permanent endpoint stays protected; do not add organiser credentials.
  3. Run when ready, then build your own calculation. Keep your working original. Export a separate copy without secrets, credential references, pinned data or saved run data, and submit both whole-number answers with the JSON on the website.

Requirements

  • An n8n instance, a registered Community Weekly Challenge account with a current participant key, and outbound HTTPS access to marketing.app.n8n.cloud.

Customization

  • Continue both Split Out lanes with native n8n nodes and ordinary expressions. Build your own solution without AI assistance. Code, Function and Function Item nodes are prohibited, including disabled or disconnected copies.
