Integration Rest API

[Ragav4]

I got a very common question, me working on Rest API integration, I recommended client using dedicated Mid Server for the Rest AP integration ( Airwatch ) for Prod, Dev and Test but client agreed saying that we can provide dedicated Mid Server for Prod but not for Dev and Test environments. Instead we can use an existing Mid Server that is running Discovery and during the non discovery hours we can schedule this integration. 

How I can justify this to customer to say that we need a dedicated Midserver for Rest API integration.?

Hi,

Can you elaborate a bit on the REST API integration use case? Why do you see a need of a dedicated MID Server? REST API as such doesn't require it but the specific use case may.

I am following this link for the integration 

https://www.servicenow.com/community/developer-articles/update-your-snow-cmdb-from-airwatch/ta-p

I was not told by the client to use the Mid Server but when I referred to some of the integration guys they referred me to use a dedicated Mid Server for this integration, I am not sure if we have to use dedicated or existing Mid Server or not having a Mid Server. 

Do we need Mid Server for this integration?

Can we use a Mid Server that is already using for discovery purpose? 

If we need Mid Server then what difference does it make of not having the Mid Server?

Could you please suggest me how to proceed further. Thanks

Hi,

Your link doesn't seem to work. 

You need a MID server if the external part is on your local network and firewalls are preventing access from the instance directly. If you integrate with another cloud service you don't need the MID server in a REST integration.

If you need a dedicated MID server or not depends mostly on the load. How many calls will be made, how much data will be processed and will that occur at the same time as other functionalities uses the same MID server with a lot load. 

There is a MID Server Fundamentals course on NowLearning that can give you more information about what to think about when setting up MID Servers.

For rest api's you do not need any mid-server if it is accessible. To check this you can use the same creds to fetch the data in the postman. 

Also if you are using mid-server then yes you do not need separate e one for any enviroment. In most of the cases once you built the integration you will going to run it on schedule. So it's better to create the schedule smartly. Also if the load is not supported then you can always increase the configuration if mid. (This is assuming you are not using mid for event management or oprational intelligence) 

Please note for above integration it should work without mid server. Let us know what you are trying to do with the integration so that we can help you out.
