After your integration is completed, Demo PSP strongly recommends testing your setup before going live. It helps you get a feel of your customers' payment experience and detect any problems at an early stage.
No need to create another shop or account for tests. Check the integration anytime - even if your shop is already working in live mode - by switching on the test mode for a transaction.
In the test mode the Demo PSP system processes requests, but doesn't send them on to the processing network for financial settlements.
Depending on the integration option you prefer, follow a suitable way to enable the test mode for your setup with the Demo PSP system.
Pay-by-link testing: Create a test product and get a payment link for it. Follow the link to make a test payment.
Payment widget testing: Create a payment token or initiate a payment widget with the
testparameter set to
If Demo PSP gets
"test": true in a transaction request, the operation is considered to be a test one.
Use test data sets
Get and view test results
After you make a test payment, Demo PSP sends you a response and a webhook notification, if set, with the result respective to the submitted test details. Besides, you can review test transactions and their details in your Demo PSP back office.
Error response with the
Duplicate transaction message
While testing the integration, you may get error responses with the
Duplicate transaction message.
Change a transaction amount for a test to bypass the Demo PSP filter which protects you against duplicate transactions made by customers. Alternatively, send the
duplicate_check parameter set to
false in your requests.
Processing test transactions
While going live, pay attention to the
test parameter value in responses and notifications not to provide your services or products for test payments.
If you are not sure about the status of the transaction (i.e whether it is live or test), send a status request to Demo PSP.
