How to connect to and authenticate an external web service from BC cloud

garth68 · 2022-04-28

I am trying to connect to the ABN Amro sandbox. The API example is as follows:

curl -X POST "https://auth-mtls-sandbox.abnamro.com/as/token.oauth2" \
-v \
--cert CertificateCommercial.crt \
--key PrivateKeyCommercial.key \
-H 'Cache-Control: no-cache' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-d 'grant_type=client_credentials&client_id=test_client&scope=account:details:read account:balance:read account:transaction:read'

The headers, body, certificate and connection are fairly easy, but I have no idea how to use the key file:

Url := 'https://auth-mtls-sandbox.abnamro.com/';
BodyContent := 'grant_type=client_credentials&client_id=test_client&scope=account:details:read account:balance:read account:transaction:read';
Headers.Remove('Content-Type');
Headers.Add('Content-Type', 'application/x-www-form-urlencoded');
Headers.Add('Cache-Control', 'no-cache');
Body.WriteFrom(ContentText);
Body.GetHeaders(Headers);

// cert = get from cert table convert to base64?
Client.AddCertificate(Cert);

if not Client.Get(Url, Response) then
Error(WebServiceError);

Any help is appreciated!!

Hello @garth68,

You need to convert the .crt and the .key to a .pfx and this new certificate is the one that you use with Client.AddCertificate(Cert).

For this conversion you can use openssl.

openssl pkcs12 -export -out NewCertificate.pfx -inkey PrivateKeyCommercial.key -in CertificateCommercial.crt

Hello @garth68,

You could save the pfx certificate in a BLOB field and the password in a text field, for the test, later you could elaborate a little more for security purposes.

And use Client.AddCertificate(Cert, Password)

The Cert in the Client.AddCertificate must be in Base64 format, so you can save in the BLOB field the certificate in Base64 o convert to Base64 if is in pfx format.

Hello @garth68,

What kind of certificate do you store in the cert table ?

Regards.

Hi @ftornero,

Thanks for the reply! I'm not sure what type of certificate it is. I'm not even sure if I'm supposed to store it in the certificate table (I can't find any help on this topic).
The certificate and key (which are freely available for this sandbox testing) are as follows:
.crt file:

In Postman I add these 2 files to the certificate setup and I can connect. But in BC cloud I have no idea how to use them. I assume that I stream the certificate to the client using Client.AddCertificate(Cert)...

The response to this Client.Get should be a OAuth2 token that allows me to get the data needed

Hello @garth68,

You need to convert the .crt and the .key to a .pfx and this new certificate is the one that you use with Client.AddCertificate(Cert).

For this conversion you can use openssl.

openssl pkcs12 -export -out NewCertificate.pfx -inkey PrivateKeyCommercial.key -in CertificateCommercial.crt

Regards.

Thanks @ftornero! I appreciate the help!!

garth68 · 2022-04-29

Hi @ftornero,

Thanks, created without a problem. How do I actually use the certificate? The functions in the Certificate Management codeunit are marked as OnPrem, and when I use the isolatedstorage.Get I get an error:

Certificate.Get('CERT0000000002');
//CertificateMgt.GetCertAsBase64String(Certificate); //marked as OnPrem
ISOLATEDSTORAGE.Get(Certificate.Code, DATASCOPE::CompanyAndUser, Cert); //error here
ISOLATEDSTORAGE.Get(Certificate.Code + 'Password', DATASCOPE::CompanyAndUser, StoredPassword);

The Isolated Storage does not exist. Identification fields and values: App Id='{56368753-DB13-4133-8BF0-6F24NNNA7A4A}',Scope='CompanyAndUser',Company Name='TestDB',User Id='{026716F0-DBEB-4417-A3E0-9FA440277933}',Key='CERT0000000002'

I'm really not sure how this functionality works because the code on the Certificate page to save the file in isolated storage calls the following function in cert management:

[Scope('OnPrem')]
procedure SaveCertToIsolatedStorage(IsolatedCertificate: Record "Isolated Certificate")

Am I missing something? I don't get an error, but I don't see how this can work....

Hello @garth68,

You could save the pfx certificate in a BLOB field and the password in a text field, for the test, later you could elaborate a little more for security purposes.

And use Client.AddCertificate(Cert, Password)

The Cert in the Client.AddCertificate must be in Base64 format, so you can save in the BLOB field the certificate in Base64 o convert to Base64 if is in pfx format.

Regards.

Thanks @ftornero . That makes sense!

Howdy, Stranger!
