Hi rahul0611,
The reasons are stated as below:
INVALID STATUS
- The transaction being queried doesn't exist on PesaPal.
- The transaction's merchant reference number is repeated on more than one transaction on PesaPal and you are using QueryPaymentStatusByMerchantRef API which you only provide the merchant reference number. In such a case PesaPal will not be able to determine exactly which payment is being queried.
It's important to avoid repeating the merchant reference. Try make it the invoice number, order number or a random string. If you must(which is not idea) repeat the reference, when checking the status use the "QueryPaymentStatus" or "querypaymentdetails" API which you must provide the transactions reference number and tracking ID hence there will only be one transaction matching your query.
FAILED STATUS
1. Credit card details are incorrect or have been rejected by the bank.
2. Mobile payments - If a client pays an amount lower than what they are required to pay. Eg, you make a purchase of an item costing KSH 103 but in your mobile payment you actually submit KSH 100. In such a case, you as the merchant can contact our support team for further assistance. Our ticketing platform can be found at support.pesapal.com. The ksh 100 will be credited to the clients PesaPal wallet account or may be reversed on request for them to re-transact.
