SAS VIYA REST/Client API to get list of model variables

H-elmu-t — Thu, 09 Apr 2020 06:06:37 GMT

Hi,

I am looking for a way to get the list of input and output variables of a published SAS Viya MAS model in a script.

Is this possible using REST API calls?
Or is there any other way to retrieve the input and output variables of a published model in SAS script?

Thanks,
Helmut

Hi @H-elmu-t,

Just an FYI. Additional info from a colleague for MAS implications:

I don’t believe that MAS retains a reliable link back to the model in MM (I could be wrong), so I don’t think pulling the input/output variable info from MM will work (the version in MM may not match what was published to MAS).

I’d recommend going directly to MAS:

Get a list of module steps (DS2 methods you can call). https://developer.sas.com/apis/rest/DecisionManagement/#get-module-steps

And then get the info for a specific step (probably SCORE) https://developer.sas.com/apis/rest/DecisionManagement/#get-a-specific-step-of-the-module

That will tell you the input/output vars.

Hi @joeFurbee,

Thanks for your feedback, that's a very good point!

I will go directly to MAS instead (as you recommended).
Best regards,
Helmut
