Problem between Pagseguro and number of installments

Question

I made the implementation of a virtual store customized in PHP language and as checkout I am using Paying.

In the implementation, the transparent checkout was used and was working correctly, but the client requested that the option of parceling the order be added. When trying to carry out parcel requisition using the API Javascript, the answer is always the same:

{"errors":{"INVALID SESSION: d4d905b585ec4d4d8056e380df70e4a5.":" 10005"},"error":true}

To make this request I am using the following Javascript method:

PagSeguroDirectPayment.getInstallments

I would like a help to solve, because as I said earlier the checkout was working correctly and the only change made was the addition of the installments.

        }
    },

Answer 1

I recently made an integration with the transparent Pagseguro, and I came across this and other difficulties.

Suppose q vc is using their official PHP library (https://github.com/pagseguro/php), follows below the problems found and how they were solved, starting with what I believe to be the cause of your problem (of course to be sure there is a need to see the PHP code):

maxInstallmentNoInterest

A common error is sending a field to the PS by JS and not doing the same by PHP. The problem is that in the specific case of this field, the library does not have an attribute of its own to send it, being necessary to make use of addParameter, thus: $psRequest->addParameter('noInterestInstallmentQuantity', 2);

Bank name

For payments via Online Debit (EFT), there is a need to inform the name of the bank, something that is not clear in the manual. For this, use the method setOnlineDebit, thus: $psRequest->setOnlineDebit(array("bankName" => 'nome do banco');

EFT vs ONLINE_DEBIT

The JS method getPaymentMethods returns a JSON whose nomenclature for online payments is ONLINE_DEBIT. However, in the PHP library this nomenclature changes to EFT. The PHP class where this is found is Pagsegurodirectpaymentmethods, and one of the ways to fix this conflict is by adding the following line in the attribute statement $methodsList: "ONLINE_DEBIT" => "eft",

I hope these suggestions can help you to finalize your project.
