Hi, You can create a config file for your own using a template that can be searched and downloaded from the internet. And you can explicitly specify the path to it in your openssl command. Thanks Lakshan

Hi Lachlann, Welcome and happy to assist. "Payment.success" response is not the last step if you are a PCI compliant merchant. You have to first decrypt the returned payload and display it to the customer to review and confirm. Then you should update the final payment information. It may contain shipping charges, etc as well. Please see my previous reply for more information on how you should do the payment update. Also you may refer the diagram I have attached. If you are not a PCI compliant merchant and if there is a third party processor or acquirer involved on behalf you, then they will do the payment update for you. Also they suppose to decrypt the initial payload and pass it back to you to display on your merchant web page. Hope this clarifies. Should you need further information and clarification, you may write to developer@visa.com with refering to this thread for faster and further responses. Thanks & regards Lakshan

Hi There, Thanks for your query. Would you like to share the following? 1. Delphi code snippet of RESTApi invoke, including how you tried to pass the certificate information during run time. 2. Steps you performed to creat PKCS12 certificate store. 3. Delphi version Best regards Lakshan

Hi Alex, Please refer the documentation Diana has advised in her reply. Also make sure following is the format of your openssl command when generating the CSR file. You have to include all the parameters, subject details in to the single line command. Also please note that there is "-PROD" as a suffix to UID value. Openssl req -new -key C:\TestPrivateKey.pem -out C: \TestCSR.pem -subj "/emailAddress=ProjectOwnerEmail@domain.com/UID=yourProjectUIDValue-PROD/CN=Your-FQDN/O=YourOrg/OU=YourOU/C=SG/ST=YourState/L=YourCity" -config "C:\temp\openssl.cnf" Thanks Lakshan

Hi, Just to provide you some additional information, which is, you have to make an update for the payment information upon client completion of making the payment from the VCO lightbox, if your payment processor or partner does not do that for you. This confirms the completion of the order and payment. Also this facilitates to calculate the final amount later with adding any shipping, discounts, etc. There are two methods to make the update. Option 1. Place following "gif" image at the completion / order confirmation page (Ex: "Thank you" page) with specifying the apikey, callid, payment attributes, and so on as query parameters. Please refer the "Visa Checkout Integration" guide for more information from page 67 onwards to understand all possible attributes you can specify. <img src=“https://sandbox.secure.checkout.visa.com/wallet-services-web /payment/updatepaymentinfo.gif? apikey=...&callId=...&currencyCode=USD&total=11.00&subtotal=11.00” /> Option 2. Make an API call to update the information. Please refer the API reference in following page. https://developer.visa.com/capabilities/visa_checkout/reference#visa_checkout__update_payment_information____update_payment_info Hope this helps. Should you need further clarifications/informaton do not hesitate to contact us again. Thanks Lakshan

Hi Eddy, We are happy to help. Could you please elaborate more such as when do you see this error, which operation/command you tried to execute? Thanks Lakshan

LakshanFernando

Hi Jm, Thanks for your query. We are looking in to it. Could you please advise the name of your project that you retrieved your APi key and secret keys in Sandbox environment? Thanks Lakshan

LakshanFernando

Hi, Thanks for your question. One solution I have tried is runtime loading of the visa checkout sdk script. After you load (display) the visa checkout button, you can then proceed with loading the following sdk. https://sandbox-assets.secure.checkout.visa.com/checkout-widget/resources/js/integration/v1/sdk.js Sample code to load a js file at runtime. var script = document.createElement("script"); script.setAttribute("type", "text/javascript"); script.setAttribute("src", "https://sandbox-assets.secure.checkout.visa.com/checkout-widget/resources/js/integration/v1/sdk.js"); document.getElementsByTagName("header")[0].appendChild(script); Please advise whether I have understood your question correctly and answered properly. Thanks Lakshan

LakshanFernando

Hi Smeet, I only can see your private key file and Visa Root Certificate file inside your JKS file. Could you please confirm those are the only files you have added in to it? You should add two more certificates, which are, 1. Geotrust certificate file 2. Application certificate file. You can download them from your VDP project dashboard. Please refer the attached screen shot as well. Once done, please give another try and kindly update us as well. Thanks Lakshan

LakshanFernando

Hi Ben, Thanks for your query. Your understanding is correct that Sandbox does not output an accurate response. Best regards Lakshan

LakshanFernando

Hi Smeet, Could you please send us a list of available keys and certificates inside the JKS file? You may use the following command. keytool -list -v -keystore C:\truststore.jks Thanks Lakshan

LakshanFernando

Hi, Thanks for your question. Please see the below code snippet. That particular callback function will be invoked upon a successful payment. So if you are getting a succesful message from that paticular function; that means the payment has been made successfully and you can display the response appropriately to the client in your web application. Otherwise, if payment has been voided/canceled or unsuccessful, one of the other functions will be invoked in respective to the out come. Hope this clarrifies and helps. Should you need further information/clarification kindly revert back to us. V.on("payment.success", function(payment) { document.getElementById("id_contents").textContent = JSON.stringify(payment); alert("payment success"); } ); Cheers Lakshan

Hi Maria, I believe our CEMEA client engagement team is now liaising with you to troubleshoot this issue. Please let me know in case you do not get to hear from them within next 24hours time. Cheers Lakshan

LakshanFernando

Hi Joe, Thanks for your question and thanks for highlighting this! Visa has provided these sample code in very basic level to provide some insight, demonstrate best practices, and as a quick starting point for developers. Therefore this is not 100% production implementation ready and we expect client developers to customize the code to integrate with their backend/downstream applications based on their requirements and use cases. For your case, you may first consume the response and then use a copy of the response to log it; as you have already done. Further, when you log the response you might have to suppress/obfuscate any sensitive data, such as PAN information, when use with certain Visa Direct APIs. These functionalities are not included in the sample code. Therefore we expect client developers to enhance/modify the functionalities. Hope above clarification helps. Should you have further concerns kindly let us know. Thanks Lakshan

LakshanFernando

Hi, Sorry for the inconvenience caused. Could you please try to accessing the following URLs and advise us? Also you may first try this in a "chrome" browser although it works fine in others as well. https://developer.visa.com/pages/support https://developer.visa.com/ https://developer.visa.com/portal/#login Thanks Lakshan

LakshanFernando

Hi Maria, Thanks for your response. I got couple of more questions for your kind response once again. Was this ATM Locator being added recently to the project after other APIs got promoted to the production? Or ATM Locator was part of other APIs when you promoted the project to production? Kindly advise. Best regards Lakshan

LakshanFernando

Hi, Thanks for your question. As you have confirmed that API access had worked fine from another local machine and JKS file seems correct; this issue most probably can be due to the fact that your program/tool in the new machine is unable to read the JKS file during the SSL handshake. Therefore could you please check whether your program has read access and paths provided are correct to the JKS file? Please let us know if issue still persist. Thanks Lakshan

LakshanFernando

Hi, Thanks for your question and interest in ATM locator API. Could you please advise us with the following? 1. What is the API you are able to access in prod environment and what is the project name of it? 2. What is the project name you created for ATM Locator or are you trying to use it under above existing project? Thanks Lakshan

LakshanFernando

Hi, Thanks for your question. I believe you are trying to test this out in our Sandbox environment. Due to having limited number of results in the test database, you might not be able to see the results most of the time. Should you require a valid response you have to promote your application to the production environment. Thanks Lakshan

LakshanFernando

Hello there, Please use "cardAccountExpiryDate" as the correct field name. Until we re-visit our documentation and correct where necessary, you may refer the sample (swagger) request payload field names as it contains the correct names in it. Once again apologies for the inconvenience caused and thank you for highlighting this. Best regards Lakshan Fernando

LakshanFernando

Hi, Thanks for trying out Visa B2B Virtual Accounts payment method APIs. Please allow us few more days to get back to you with the correct field name. Appologies for the inconvinience caused. Best regards Lakshan

Hi Srinivas, Thanks for exploring out Visa Direct functionalities. Below are the replies to your queries. 1. If our service gateway times out while calling Push Funds/Pull Funds API is there anyway to get the status of the submitted(but unknown status) transaction? Yes. If your gateway connection terminated abrubtly due to any reason before receiving any response from Visa, what you can do is to to re-submit the same request with exact request payload values. Visa will send you a response with "StatusIdentifier" value if the initial transaction you submitted is still processing at Visa. Otherwise it will send the transactionIdentifier. By re-submitting the exact payload, it does not make duplicated the transaction. Instead it will only return the status of the initial request. Alternatively you can use the Reports API to retrieve status of all the transactions you have submitted to Visa. 2. As per the GET API doc, it says need to pass "StatusIdentifier", is it same as RetrievalReferenceNumber sent in the POST API request? No. Status identifier is a value returns by the Visa if the api call you make times out at the Visa end. It is not same as the RetrievalReferenceNumber. Hope my answers helps. Please let us know if require further clarifications/information. Best regards Lakshan

Hi Vasyl, We are looking in to this and update you asap. Thanks Lakshan

Hi Chid, This error can occur mostly with Java or java technology based middleware tools when it is unable to open the JKS file (or the private key inside the jks file) in order to establish the SSL connectivity with Visa. In order to investigate further, kindly provide us the following information. Also please follow the steps mentioned further below and advise with the results. REQUIRED INFO ------------------- 1. Project name and project owner email address in VDP 2. What is the technology you are using to invoke the API? Ex: Java/Python/PHP or any middleware tool such as Datapower,SoapUI, etc 3. Do you use a JKS file? 4. Runtime environment? (Windows/unix/anyother) STEPS (Applicable only if you are using a JKS File) --------------------------------------------------- 1. Please check the JKS file has read access and the paths are properly set. 2. Please check all the certificates has been added to the JKS file. Following are the required certificates assuming you are testing in Sandbox environment. a) VISA Root certificate b) Geotrust Certificate c) Application Certificate file d) Private key file (in p12 format) 3. JKS file password and private key password is same Best regards

LakshanFernando

Hi Niks, Could you please let us know the exact URI and your test application name registered in here? Thanks Lakshan

LakshanFernando

Hi Raj, Yes your format of the request now looks ok and I was getting a successful response with it. Are you able to share the x-correlation-id value with us which you can obtain from the response header? You may make another API call and share the new value. With that we can check our logs and see what is the exact payload we have received. Ex: 'X-CORRELATION-ID': '1498477644_985_70_l55c006_VDP_ARM' Cheers

LakshanFernando

Hello Raj, Thanks for using and exploring VISA APIs. While Sanobar is working on to understand the root cause, can you please confirm the following? You are using the below URL for Request Virtual Account https://sandbox.api.visa.com/vpa/v1/requisitionService If "yes" for above, then the payload format of your request is invalid. It is the format for "Virtual Card Requisition" api to update virtual card requisitions. Kindly use the sample format in the documentation page, retry and let us know the results. Best Lakshan

LakshanFernando

Hi, Your understanding is correct that Sandbox does not output real/upto date exchange rates. In production environment you can expect up to date actual and correct rates. Best Lakshan
