How to connect Slack and Xero

Create a new workflow and add the first step

In n8n, click the "Add workflow" button in the Workflows tab to create a new workflow. Add the starting point – a trigger on when your workflow should run: an app event, a schedule, a webhook call, another workflow, an AI chat, or a manual trigger. Sometimes, the HTTP Request node might already serve as your starting point.

Slack and Xero integration: Create a new workflow and add the first step

Automate invoice processing with Gmail, OCR.space, Slack & Xero

How It Works Trigger: Watches for new emails in Gmail with PDF/image attachments. OCR: Sends the attachment to OCR.space API (https://ocr.space/OCRAPI) to extract invoice text. Parsing: Extracts key fields: Vendor Invoice number Amount Currency Invoice date Due date Description Validation Logic: Checks if amount is valid Ensures vendor and invoice number are present Flags high-value invoices (e.g., over $10,000) Routing: If invalid: Sends a Slack message highlighting issues Labels email as Rejected If valid: Logs the invoice into Google Sheets Sends a Slack message to the finance team for approval After approval, creates a draft invoice in Xero Labels the email as Processed in Gmail Set up steps • Estimated setup time: 45-60 mins • You’ll need connected credentials for Gmail, Slack, Google Sheets, and Xero • Replace the default API key for OCR.space with your own (in the HTTP Request node) • Update Slack channel IDs and label IDs to match your workspace • Adjust invoice validation rules as needed (e.g. currency, red flag conditions) All detailed explanations and field mappings are provided in sticky notes within the workflow.
