As a user, I'd like to be notified when a refund is processed by the payment provider. On the model of the invoice.payment_status_updated webhook, it would be useful to have credit_note.refund_status_updated .

The endpoint GET /invoices allows users to filter invoices by date of issue (query parameters issuing_date_from and issuing_date_to ). The same query parameters would be useful for the endpoint GET /credit_notes .

With Plural you can deploy, secure, and scale open-source applications on your cloud in minutes. Could be great also for the project visibility and accessibility ! https://www.plural.sh/ https://docs.plural.sh/adding-new-application

For self-hosted users, it would be useful to have access to data points to set up Prometheus monitoring.

Examples of messages that could be useful: Webhook when a coupon is applied to a customer account via the user interface; and Webhook when a coupon has been fully consumed.

Currently, the retry function is only available for failed webhook messages. It would be useful to be able to resend successful messages as well (e.g. the message was received but the webhook URL was outdated).

When using Lago and the Stripe integration, we'd like to be able to define a success_url and cancel_url for each checkout session. This request relates to the following endpoints: /customers/:customer_external_id/checkout_url /invoices/:id/payment_url This would allow us to display different web pages depending on the workflow (e.g. specific page for payment method registration and specific page for successful payments).

Stripe provides tokenized card information that we would like to retrieve through the Lago API. https://stripe.com/docs/api/tokens/retrieve Showing the card type, last 4 digits and expiration date would enhance the customer experience. For instance, enterprise customers would be able to check whether they've used the right payment method (e.g. hardware card vs recurring services card).

It would be great if we could use the external ID or Lago ID of the customer/subscription to retrieve a specific webhook message.

We are looking for a webhook event that will notify us when an invoice is overdue per the net payment terms.
