Posted on by Abdullah Zafar

Hi,
I want to consume a third-party API in business central On-prem and the API has a requirement for Certificate, I have the certificate file and password but I am not able to use them. I have written code in C#, and it works correctly but I am not able to do the same in Business Central, here is my C# application code.

I am not able to understand how to pass this certificate in Business Central. I have written the code in AL but it's not working, I have explored some standard codeunit but not able to upload the certificate

Anyone knows how to consume it,
Best Regards

hi

in my opinion you'd better develop a dll in C# and put it in the addins of BC on prem and do whatever you need to do

Hi, Yes that is an option as well, but I managed to get the desired result from business central standard functionality for Certifications, I have upload then certificate in business central and then used Base64 of the certificate, Some procedures that I have used have scope of On-prem, anyone who is trying it in SAAS, need to be careful,

Hi Abdullah,

Thanks for the response. The standard certificate management functionality does not work on SaaS. I managed to get it to work with a combination of both .Net and AL:

Use a .Net app or openssl to create a .pfx file of the certificate from the cert and key PEMs

Import the Certificate file manually and storing it in a custom Blob field:

Read the Blob and convert it to base64 to get certificate for http client

using the certificate with httpclient.addcertificate(certificate,password)

I hopes this helps someone.

Thanks
