I am using PHP library for tokenization and tried to run the test case, but it is returning error message and the response does not contain any data.
I also tried the step by step guide (https://developer.mastercard.com/platform/documentation/security-and-authentication/generating-and-configuring-a-mastercard-api-client/#step-by-step-guide) and that is also returning the same result. Please see the attached screenshot for reference.

After executing the below line api-client folder is created.
openapi-generator-cli generate -g csharp-netcore -i *.yaml -c config.json -o api_client

I have chosen CSharp but when I try to oepn the solution using VS2015 it is unable to load the project.

Which tool is needed to open the api-client project?

In this generated model
Acme.App.MastercardApi.Client/Model/AuthenticationMethods.cs

the id is of type int, but the openapi spec says string

this causes an error when the API client tries de-serialize a response with a large ID, essentially ending up with null Data:

{
    "StatusCode": 200,
    "Headers": { ... },
    "Data": null,
    "ErrorText": "JSON integer 3123456789 is too large or small for an Int32. Path 'authenticationMethods[0].id', line 7, position 22."
}

was this client generated by an older openapi spec perhaps?

Heya, I generated a C# client from the openapi spec.

I noticed the generated API client will call paths relative to sandbox
For example TokenizeApi.CreateTokenizeWithHttpInfoAsync

Notice the path ...PostAsync<TokenizeResponseSchema>("/digitization/static/1/0/tokenize",

This works in sandbox,
baseURL https://sandbox.api.mastercard.com/mdes + path /digitization/static/1/0/tokenize

However if I were to use the same client in mtf or prod, the resulting path would include /digitization/static/1/0, which would fail.

According to the api reference, the environment domains are:

prod    https://api.mastercard.com/mdes/digitization/1/0/tokenize
mtf     https://api.mastercard.com/mdes/digitization/mtf/1/0/tokenize
sandbox https://sandbox.api.mastercard.com/mdes/digitization/static/1/0/tokenize

I could hack TokenizeApi (and the other Api classes) to ...PostAsync<TokenizeResponseSchema>("/1/0/tokenize",
and use different baseURLs like

https://api.mastercard.com/mdes/digitization
https://api.mastercard.com/mdes/digitization/mtf 
https://sandbox.api.mastercard.com/mdes/digitization/static

Works, but it's a hack. What am I missing here?

I followed this tutorial https://developer.mastercard.com/mdes-digital-enablement/documentation/tutorials/create-a-new-project/#6-download-client-encryption-key-sandbox

I download this github project for c#

I modified the specified fields in the doc link

but when running the test, we get all fields null, except responseId

please help

Hello, I have implemented this client code (csharp) for the Mastercard merchant mappings, getting an 'Internal Server Error' in response while posting the request to Mastercard Directory Services as it includes encryption and decryption.
Unfortunately, there isn't a lot of details in the error:
Response:
{"Errors":{"Error":[{"Source":"SYSTEM","ReasonCode":"SERVICE_ERROR","Description":"","Recoverable":false}]}}

P.S. I am getting a successful response while fetching an existing sample mapping record.
Support isn't helpful yet so... Thanx in advance.
