Getting when testing MLE enabled API on postman

[Chefane]

I am curently testing MLE on postman using request to pay API (initaiate transaction) I have configured everything correctly, but I am getting an error pointing to the payload. I am using MLE endpoints namely encrypt, VDRequest and decrypt, when encrypting, everything works fine, I can get the output which is encrypted data, but when validating it, I get an error, below is my payload:

{

"product": "VD",

"useCase": "P2P",

"paymentRequests": [

{

"debtorLastName": "B.",

"debtorAlias": "+447709123457",

"debtorAgentCountry": "UA",

"debtorCountry": "UA",

"requestedAmount": "100.00",

"requestedAmountCurrency": "UAH",

"endToEndId": "RFPid0001",

"debtorFirstName": "John",

"debtorAgentId": "VD123445",

"debtorAliasType": "MOBL"

}

],

"dueDate": "2021-03-17",

"requestMessageId": "GG9983636387737JH",

"settlementOptions": [

{

"settlementSystem": "VISA_DIRECT",

"primaryAccountNumber": "4145124125553228"

}

],

"creditor": {

"creditorCountry": "UA",

"creditorAgentId": "12379879797989",

"creditorAgentCountry": "UA",

"creditorAlias": "+1231231234",

"creditorLastName": "F.",

"creditorAliasType": "MOBL",

"creditorId": "BL1234567890",

"creditorIdType": "Agent",

"creditorFirstName": "Alex"

},

"creationDateTime": "2024-03-03T13:50:47Z"

}   this payload can get encrypted but when using VDRequest I am gettting below error:

{

"timestamp": 1709466577960,

"path": "/edge/api/internal/v1/requestToPay",

"status": 400,

"error": "Bad Request",

"requestId": "1b52cfb7-137630"

}
any recomendation on what causes this.

Hi @Chefane,

You can refer to the Visa Developer Error Codes page for the cause/resolution. I've copied and pasted the 400 error code cause/resolution for you below. 

Payload and URI Error Codes

HTTP STATUS	HTTP CODE	CAUSE/RESOLUTION
BAD REQUEST	400	This error could be due to a variety of reasons. Check for the following: The url has a space after the ?. Whitespace issues, in general, anywhere in the url. Ideally the following fields need to be checked for correctness:  URL  Query params Or The API endpoint you are trying to use only supports Two-Way SSL authentication. Please ensure you are not using any other token type. Or Invalid input found in the request payload.
