Learn how Activity log entries appear when a backdated Subscription attempts its initial payment and enters dunning. These records help you identify failed payments, track which dunning step was reached, and see whether the signup ultimately succeeded or failed. Reviewing this activity makes it easier to troubleshoot payment issues and determine the next action for the Subscription.
Go to Subscriptions, select a Subscription, then select Activity in the sidebar to view its log.
When dunning is triggered for a backdated Subscription, the Activity log records messages based on the payment outcome and the current dunning step. Use the recorded activity to determine the next step, such as contacting the Customer, updating payment information, or reviewing your dunning schedule.
| Scenario | Activity log entry |
|---|---|
| Payment fails and the Subscription reaches a dunning step that isn't the final one. | Payment failed, dunning step X of Y reached |
| Payment fails on the dunning step that cancels the Subscription or marks it Unpaid. | Payment failed, dunning step X of Y reached, signup failed |
| Payment succeeds and the Subscription activates. | Successful signup for Customer Name |
X and Y are the current step number and the total number of steps in the Dunning Schedule.
An intermediate step's entry doesn't confirm whether the signup ultimately succeeds or fails. Only the final step's entry, or the separate Successful signup entry, confirms the outcome.
