How to create an app on SNOW with integrations with on premise Web Server (not exposed to Internet)

[jayantseth]

I want to create an App on SNOW which will call APIs on an on premise web server, this web server is not exposed on the Internet and hence SNOW app cannot directly call APIs on it, Should I use MID Server to route all APIs from SNOW to Local on premise web server ?

or is there any other approach by using some Integration hub app ?

I am using App Engine Studio to build the SNOW app, please help me to understand how this can be achieved.

Any help will be greatly appreciated, thanks in advance

Hi @jayantseth 

Are you referring SNOW as ServiceNow then its wrong, SNOW and ServiceNow are 2 different products. You can use AES to build that, but before that I will recommend try to make a high level design which tell you how to start in AES.

HI Atul, 

Thanks for your response I want to use AES to make this app, I have basic understanding of AES but I could not find any option for achieving the below :
1. Trigger APIs on local server which is not exposed to Internet. 
2. Fetch response from local server back the Service Now app ( build using AES )
Can you let me know what articles or online documents I can go through to achieve this ?
and Can we leverage MID Server as a proxy or some sort to forward REST API requests from Service Now app ( build using AES ) to the on premise local server ?

Hi @jayantseth 

Practically, I don't have much idea about this. I will mainly say, please consider @AshishKM  @ChrisBurks' inputs in this.
