Hi Libby, Emma API called from the .NET DLL - is that a RESTful API? If it is, then it is "straightforward" REST calls from PowerBuilder.

Otherwise, you may call the .NET assembly using "COM callable wrapper" via OLEObject. In upcoming PB 2019 R2, the new .NET interop allows you to call the .NET assembly directly instead of going through COM and OLEObject.

i assume this is the crm you are talking about:

http://api.myemma.com/

this provides the REST api call list.  You use the features in PB 2017/19 to make HTTP calls to their platform.

Thanks for the responses.  Yes, that is the documentation for the Emma API.  I need to provide a private and public key (which I have) to allow this to work but can't figure out what the endpoint of that would be and how to make the call.  Can anyone help?

after a quick look at their site, i saw some example calls: (http://api.myemma.com/#)

Now we’ll need to set the URL for the API call. The endpoint for all of our API calls is https://api.e2ma.net/. NOTE: You must use TLS version 1.1 or higher to connect. TLSv1 and all versions of SSL ciphers (e.g. SSLv2, SSLv3) are not supported.

// Set URL
$url = "https://api.e2ma.net/".$account_id."/members/add";

So, the main url is : https://api.e2ma.net

then just add the rest of the endpoint as per the specs

Thanks for the response.  I had figured out that part, but the piece that I don't know about is how to provide the authentication keys.  I have a public and private key and I see in the examples that you have to send those in to be authenticated, but I can't figure out how to go about doing that.  I looked at JWTToken (or something like that, sorry, doing this from memory), but it needs a URL and I can't figure out what that would be for authentication.  I don't think it's just the base URL.

ok, you are looking for how to do authentication. they seem to only have PHP examples, which i am not familiar with. Check with the emma developer, but it might be HMAC Authentication that they are doing. You would need to get the actual rest request from them. Typically you send an auth header that is a value generated from the other headers and signed with HMAC.
I have done HMAC auth with azure, and it is certainly doable, but microsoft provides full documentation.

Thanks for the reply.  I think I'm going to switch gears and use the .net wrapper they have.  I can compile this into a .dll and make calls to it but I have never added a .dll to a PB project before.  How do I go about doing this?  Thanks.

Armeen,

When you say "wrap it as COM", can you point me to some documentation that will tell me how to do that?  I'm not able to wait until April. Thanks!
