How to Connect Chargebee to n8n

To begin building financial automations, you need a stable connection between your billing portal and your workflow engine. This connection allows secure, real-time communication of checkout events and account upgrades. Here is how to configure the integration in three concrete steps:

1. Retrieve the API Key from Chargebee: Log into your Chargebee administrative dashboard. Navigate to Settings, click on Configure Chargebee, and select API Keys. Click on Add API Key and choose a read-write key. Copy this newly generated token and keep it secure. Note your Chargebee site name, which is the subdomain prefix of your portal URL (for example, if your admin URL is company-portal.chargebee.com, your site name is company-portal).
2. Create the Credential in n8n: Log into your workspace, and navigate to the Credentials tab on the left-side panel. Click on Add Credential in the upper right corner, search for Chargebee, and select it. Input your site name into the designated field and paste the API Key you copied. Click the Save button. n8n will test the authentication; once successful, your workspace is connected.
3. Add the Chargebee Node: Create a new workflow canvas. Drag the Chargebee Trigger node into the workspace to start workflows automatically when events occur, or use the standard action node to run calculations on demand. Choose your saved credential from the dropdown. In the trigger settings, select the events you wish to capture, such as customer_created or subscription_changed, and toggle the node to active.

Workflow 1: Synchronizing New Chargebee Customers with HubSpot CRM

Aligning marketing and sales teams requires complete visibility into active accounts. When a customer upgrades their billing plan, billing details must reflect inside your CRM immediately to prevent duplicate contacts and out-of-date sales activities.

How It Works

This workflow runs instantly using the Chargebee Trigger node configured to listen for the Customer Created and Customer Changed events. Once the payload is received, n8n parses the customer's email, name, and subscription tier. The workflow routes this data directly to a HubSpot Node. First, the HubSpot Node is configured with the Search operation to check if a contact already exists with that specific email address. Using an If Node, the workflow splits: if the contact exists, n8n executes an update operation to append custom billing fields such as current_plan_id, subscription_status, and mrr_value to the contact record. If no matching contact is found, n8n creates a brand new HubSpot lead with the subscription details populated, setting their pipeline stage to Paying Customer.

Real-World Example

Consider a growing software company selling seat-based plans. A client signs up for a trial using their corporate email. Days later, they upgrade to the Pro Plan for $150 per month. Chargebee records this transaction, prompting n8n to search HubSpot for their contact card. The workflow finds the lead and updates its status to Closed Won, sets the contract value, and logs an activity note. This updates HubSpot to remove the contact from cold marketing sequences and add them to the product newsletter.

Pro Tips

Always map your currency fields correctly when passing values to CRM software. Chargebee represents currency amounts as integer cents (for example, $49.00 is returned as 4900). Use an n8n Set Node or Code Node with a simple mathematical expression to divide the amount by 100 before updating your CRM. This ensures your sales metrics and report charts display correct decimal values instead of inflated numbers.

Workflow 2: Alerting Slack and Triggering Customer Outreach on Failed Payments

Involuntary churn from expired cards is a significant drain on subscription revenue. Resolving this requires direct outreach before account suspension.

How It Works

This dunning workflow initiates when Chargebee fires a Payment Failed event. The trigger node captures a payload filled with details: the billing contact email, the failing invoice ID, the specific decline reason (e.g., insufficient_funds or expired_card), the invoice amount, and the current retry attempt. First, the workflow passes this data to an n8n Code Node. This node runs a short JavaScript snippet to format a friendly, readable summary. The output goes to a Slack Node, which posts a structured notification to your internal #finance-alerts channel, enabling customer success representatives to view the failure details. Simultaneously, the workflow routes the email and customer details to an email service provider node, like Resend, which sends a personalized email containing a direct link to the customer self-service billing portal.

Real-World Example

An enterprise subscriber's credit card fails renewal due to expiration. Chargebee registers the failure, prompting n8n to send a Slack alert: 'Declined: Client ($1,200) - Expired Card.' Simultaneously, n8n sends a personalized email with a portal link. The customer updates their card details quickly, preventing service interruption.

Pro Tips

Do not send an email alert on every single retry attempt to avoid frustrating customers with repetitive notifications. Use an n8n If Node directly after your trigger to inspect the current_billing_cycle_attempt variable. Configure the workflow to only send customer outreach emails when this attempt variable equals 1 (for immediate action) or 3 (as a final warning), while letting standard Slack alerts run on every attempt for your internal team to monitor closely.

Workflow 3: Automated SaaS Account Provisioning After Successful Payment

Providing immediate account access after checkout is essential. If users have to wait hours for manual setup, their onboarding experience suffers.

How It Works

This automated workflow starts on a Chargebee Subscription Created or Subscription Changed event. First, n8n checks the status of the subscription. Using an If Node, the workflow filters out trials and pending payments, verifying that the status is set to active and the payment state is success. Next, the workflow routes the subscription plan ID to your core application. If your application database is PostgreSQL or MySQL, n8n uses the native Database Nodes to run an upsert query, creating the user profile and setting their maximum allowed seat count based on the plan purchased. If your app relies on an API, an n8n HTTP Request Node makes a POST request to your backend provisioning endpoint, securely passing the user's email, plan tier, and subscription ID in the request body.

Real-World Example

An online design platform uses Chargebee to sell monthly packages. A user signs up and purchases the Creative Team plan with five seats. The webhook fires, and n8n processes the payload. It executes a POST request to the platform's user-service API. The API creates a workspace, sets the seat limit to five, and marks the account as active. Once the API returns a 201 Created response, the workflow triggers a transactional email containing the secure login link, letting the creative team log in and start working immediately.

Pro Tips

Implement error handling on your database and API nodes. If your database server experiences a brief period of downtime, the provisioning step might fail, leaving a paying customer with no account. Configure your n8n nodes to retry on failure or use an Error Trigger node to send an urgent Slack notification to your development team so they can resolve the provisioning issue manually.

Workflow 4: Automated PDF Invoice Generation and Delivery via APITemplate.io

B2B customers often require customized VAT invoices with specific company registration details that standard templates cannot easily accommodate.

How It Works

This workflow begins when Chargebee generates an invoice, triggering the Invoice Generated event. The webhook payload contains nested arrays of purchased line items, discounts, VAT rates, and custom tax IDs. n8n extracts this data and sends it to an APITemplate.io node. Using a pre-designed HTML or CSS invoice template, APITemplate.io renders the fields into a beautiful, standardized PDF. The output is a raw binary file within n8n. The workflow then splits the output into two branches. The first branch uses an AWS S3 Node to archive the PDF invoice in a secure compliance bucket. The second branch uses an email delivery node to send the customer a clean email containing their invoice as a physical attachment, bypassing generic HTML receipts.

Real-World Example

A German enterprise client buys a SaaS subscription. They need their local VAT ID and corporate registration details displayed on their invoice for corporate compliance. Chargebee collects these fields during checkout. Once the invoice is generated, n8n parses the data and passes it to APITemplate.io, which dynamically renders a VAT-compliant PDF. The PDF is saved to an S3 folder structured by year and month, then emailed directly to the client's accounting department, keeping your billing fully compliant with local regulations.

Pro Tips

To format arrays of subscription line items before passing them to external PDF engines, use an n8n Code Node. Write a simple JavaScript map function to transform raw pricing arrays into a clean, structured HTML list or table. This ensures multi-line invoices render perfectly without overlapping text or breaking page margins on your finished PDF document.

Workflow 5: Tracking Monthly Recurring Revenue (MRR) Changes in Google Sheets

While dashboards provide real-time metrics, building custom financial models and forecasting growth requires structured historical data in a spreadsheet.

How It Works

This analytical workflow automates spreadsheet logging. We configure a Chargebee Trigger node to monitor subscription lifecycle events, specifically Subscription Created, Subscription Changed, and Subscription Cancelled. Once an event fires, n8n receives the old subscription object and the new subscription object. The workflow uses an n8n Code Node to calculate the net MRR delta. For example, if a plan changes from $50/month to $120/month, the delta is positive $70. If a plan is cancelled, the delta is negative $50. Finally, the workflow uses a Google Sheets Node to append a row containing critical metrics: transaction date, customer name, subscription ID, old MRR, new MRR, net change, and event type. This builds a clear ledger of every revenue event.

Real-World Example

A founder wants to track revenue growth and contraction. During the day, users upgrade and churn. For each event, n8n calculates the revenue change and records it in Google Sheets. The founder can easily run custom formulas on this clean data without running complex SQL queries.

Pro Tips

Always convert cents to standard currency units. Chargebee returns financial numbers as integers representing cents (e.g., $100 is returned as 10000). In your n8n calculations, divide the raw fields by 100 before writing them to Google Sheets to ensure your columns display correct dollar values, making your spreadsheets readable for your accounting team.
