Hello! I'm currently working on a project to build a PowerApp using data from one of our internal business systems and am hoping to make sure that I've got the right idea on whether or not this is possible with PowerApps today. Because of a huge amount of business logic that happens with the source system we need to use the SOAP API from the legacy system vs. the PowerApps database connector (there's just way too much logic that we can't change within the source system that would be ignored if we did direct database connections).
Is it possible to build a custom API (presumably hosted in Azure and connected to our internal network with an Azure Gateway) that would interface with the internal-network-only SOAP services from the legacy system and then expose a REST API to be used by a PowerApp? I found https://powerapps.microsoft.com/en-us/tutorials/register-custom-api/ and other supporting docs that seemed to indicate that it is but after the last couple of months wanted to make sure I was the on the level with that approach.
As a bonus we have a Government O365 and Azure subscription which bring certain challenges to what is available, do you guys have any insight into other challenges that might be caused by having Government subscriptions? We're working on getting Commercial Azure right now but we've had some trouble getting a straight answer as to what is available within the Government space for certain things.
I would hugely appreciate any thoughts or help you might be able to provide, thanks!
I will escalate your issue to pg and will update if I got further reply.
Have you had a chance to check into this further? After some extra research with my team it looks like we might need to use multiple different record types within the power app and I'm wondering if those should just be set up as individual Custom APIs so that each one can be it's own datasource and hopefully be used in the app. Can PowerApps use multiple related records of different types when using a custom api?
I am trying to create a PowerApp which connects to an in-house REST API.
Since this is the closest discussion around the topic, it would be great if you let us know of a suitable way to implement this.
Appreciate your early response.
The following blog post contains details on how to connect to custom APIs.
You can also refer to my post here, which includes C# code that you can adapt to suit your needs.
Thanks for your response @timl. I have already gone through the steps to connect to custom API's that are hosted on Azure.
What I am trying to do now is to connect to In-house RESTful web services. These are not accessible outside of the Company network.
I came across this blog which describes the steps to create a MS Azure Virtual network and connect to an internal network through VPN, but I am not completely sure if this is the right direction to move towards.
The way to connect to internal RESTful services is to install and to access your services via the on-premises data gateway.
When you create your custom connector, you can tick the option to connect via the gateway.
