Stripe integration

​

Integration setup

To set up the integration with Stripe through the user interface:

1. In the side menu, select “Settings”;
2. Select the “Integrations” tab;
3. Click “Stripe” and enter your Stripe API key (locate your API key); and
4. Click “Connect to Stripe” to confirm.

​

Customer information

To collect payments automatically, the customer must exist in both the Lago and Stripe databases.

​

New customer

If the customer does not already exist in Stripe, you can first create them in Lago, either via the user interface or the API. When adding customer information, you must:

1. Define Stripe as the default payment provider;
2. Leave the field associated with the Stripe customer ID blank;
3. Enable the option to automatically create the customer in Stripe; and
4. Define payment method options for this customer. Possible values are card and sepa_debit.

The customer will automatically be added to Stripe. Stripe will then return the customer ID, which will be stored in Lago.

3. Disable the option to automatically create the customer in Stripe; and

Note that Sepa Direct Debits are only available for invoices in EUR currency.

Stripe Checkout: storing customer’s payment method information

When Lago automatically creates a customer in Stripe, you will receive a checkout link from Lago to facilitate the storage of your customer’s payment method information.

The payload sent by Lago will have the following structure, with the checkout link stored under checkout_url:

{
  "webhook_type": "customer.checkout_url_generated",
  "object_type": "payment_provider_customer_checkout_url",
  "payment_provider_customer_checkout_url": {
    "lago_customer_id": "88d23508-47fd-46bb-a87e-50c50f3cb371",
    "external_customer_id": "hooli_1234",
    "payment_provider": "stripe",
    "checkout_url": "https://checkout.stripe.com/c/pay/prod_c15sTbBMLep5FKOA9b9pZBiRBBYYSU1IJ5T89I5TTtpKgzE380JSmxnVYz#fidkdWxOYHw"
  }
}

By utilizing this provided checkout link, your customers can perform a pre-authorization payment. It’s important to note that the pre-authorization payment will not collect any funds from the customer. Once the pre-authorization is confirmed, Lago will send the payment method details and securely store them into Stripe for future transactions.

​

Default payment method

When you add a new payment method in Stripe, Lago automatically sets it as the default. This guarantees that Lago uses the latest payment method for a customer. However, if you manually designate one of multiple payment methods as the default, Lago will use it for payments instead the most recent one.

​

Payment intents

Once Stripe is connected and the customer exists in both databases, you can start collecting payments.

Each time a new invoice with an amount greater than zero is generated by Lago, a payment intent will automatically be created. Stripe will record the invoice ID and process the payment. If the payment is successful, the status of the payment will switch from pending to succeeded.

If the payment fails, the status of the payment will switch from pending to failed and Lago will generate an invoice.payment_failure webhook.
