KalplexDevelopers
The GoCardless sandbox behaves like live but moves no money. Use it with Kalplex's Test mode to rehearse the cases that matter: failed debits, refunds and blocked accounts.
| Scenario | How to trigger it | What to check in Kalplex |
|---|---|---|
| Mandate becomes active | Complete a signing link with sandbox bank details | Customer shows an active mandate with bank and last digits |
| Payment collected | Use GoCardless's scenario simulators on a payment | Status moves to confirmed, then paid out |
| Payment fails | Simulate a failure on a submitted payment | Status shows failed with the reason; Retry is offered |
| Charge-back | Simulate a charge-back on a collected payment | Status shows charged back; returns count updates |
| Disconnection | Revoke Kalplex in the GoCardless dashboard | Settings shows the account as not connected |
Refunds are disabled in the GoCardless sandbox until GoCardless API support enables them for your account.
