How to set up Azure API Management for mult-tenant API - azure-api-management

I have multi-tenant application, which exposes some API for our customers to use. I would like to expose it using Azure API Management. Mostly to provide Development Portal to our customers, which I find very useful, and maybe use some other features.
If I understand correctly, our customers will set up their own subscription keys for authentication, which API Management proxy will validate.
Question: How can I link and identify user/subscription to the tenant of my application, to ensure that only data from this tenant are returned.
One direction I can see to explore is to use delegated sign up, which I guess will help me to link subscription to the tenant. But then still the question is how to get user id in my backend API?
Any direction to documentation or samples is very appreciated

You could create separate groups in APIM to represent your tenants and then put users into those groups using delegation hookups. Withing APIM policy in expressions you can reference context.User.Groups to list groups user making the call belongs to and forward that information to backend.
Alternatively you could use Note field to store tenant name and access it as context.User.Note. Or if you're willing to store mapping on your side the just take an id context.User.Id.
All of above could be passed as a header using set-header policy like:
<set-header name="userId">
<value>#(context.User.Id)</value>
</set-user>
All scenarios would require you to have delegation setup to fill this information automatically for every new user created.

Simple Esri/ArcGIS Online connection using a link or iframe

I was asked by a potential client if I can have my software interact with Esri/ArcGIS Online.
Use case: users is logged into SomeRandomSoftwareApp and is looking at a Widget, this Widget includes an Esri asset id, the user clicks a link that passes that ID to Esri/ArcGIS Online and behind the scenes the user is logged into Esri and they see the data associated with the Esri/ArcGIS Online.
Thanks, Keith
If I understand correctly, you have two options for this: API Keys or Application Credentials.
The first one, is a permanent token generated by the owner of the data that will allow the application easy access to it. This is still in beta, and it was not ready for use the last time I check some time ago.
The second one, the owner of the data will generate credentials for your application. With this credentials you will have to request a token each time you want to access the data, all this via OAuth 2.0.

How to hide my product and API from other developers in centralized shared Azure APIM service instance?

We have a centralized development instance for Azure API Management Service where developers from different agencies/organization creates their Products, API and subscription. Essentially they have contributor role on resource group of APIM instance. This is a centralized shared APIM instance.
I can probably create a Custom RBAC role that allows me to edit only my API but not sure how to hide my own API and products from others.
Is there a way for developers to hide their Products and API entirely from other developers in Admin portal as well as in Developer portal?
Have you tried implementing the restriction at the product level?
Check your user list.
Create a group with by selecting the required members.
Create an product( Add required APIs) -> Go to access control -> Add a group (you may remove the Administrator group)

How do i create api keys for users on my client instead of developer portal offered in azure api management?

I have an enpoint in my MERN app which I would like to expose to developers.
I came across APIM and would like to use it.
After going to the documentation I would like to know how do I can use APIM for my specific enpoint and where I allow users to generate API's in my client side react app.
I am also going through the API management API. but don't know how to generate user specific API keys...
You could simply mimic what the Developer Portal does using APIMs REST API.
If you are using the Consumption Tier of APIM, you can just create a standalone subscription using the Create or Update Subscription API. Yon don't have to set properties.ownerId in the request payload here.
On the other tiers, standalone subscriptions are not supported yet (but will be as mentioned in the official announcement blog under New Features), so you will have to create a user first using the Create or Update User API and then create a new subscription mentioning this user under properties.ownerId as /users/{userId}.
Since these REST APIs call the Azure Management API, you shouldn't be making these requests from the client and instead should be calling this from your backend.

Azure API Management - User Metadata

I am using Azure API Management to provide API gateway for some APIs. To set up a policy for a particular Api, I have used a Property(Named Value) to restore user metadata and then I assign it into a Variable in incoming request body. When adding a new user I need to add metadata for the new user in to the json. The property value has grown and exceeded the limit now and I cannot add more info to it anymore. I am wondering what the best way is to restore my large metadata in order to be accessible in API Management policy?
Update1:
I have switched the Authentication process from Azure to Auth0 so I can add the user metadata to Auth0 app_metadata and then in Azure policies I validate JWT from Auth0 and obtain token claim(app_metadata) explained in this article. By doing so I can solve the large user metadata (json) issue however this doesn't solve other non-related user metadata stored in other Properties(Named Value) and moreover the API gateway inbound policies are growing and becoming a huge bunch of logic which is not easy to manage and maintain.
At this stage I am looking for a solution to handle all the API gateway inbound policies in a better way and more manageable environment i.e. C#. So my two cents is to implement the API gateway inbound policies in a new .net Api and call this new API in the existing API gateway inbound policies so that it can play a bridge role between Azure API gateway and existing API however I'm still not sure if this is acheivable and whether existing API can be called via new API directly or it should be called via Azure API gateway in some way!
At this point you have to either store it in multiple variables or hardcode it in policy directly.
After more research I ended up with this solution which basically suggests to restore user metadata in Azure Cosmos DB and call Cosmos API in API Management Policy to access to the metadata and also the Cosmos API call can be cached in the policy.

What is the intended use case for app auth and app users?

I am trying to understand what is the intended use case for app auth and app users. Im basically thinking about building an app that would use Box to store data of users that would subscribe to our service. Our service would allow each user to access and view their data.
If I have an account that basically owns the data of all the subscribed users, can I use the enterprise access token as a base for authentication while using the user account token to restrict the user to only viewing the data from their specific sub directory. Or do I have to have a unique account with its own api key for every user?
I hope this makes sense. Any assistance would be appreciated.
Thanks.
App Auth and App Users -- which is officially called Box Platform -- is essentially a white-labeled version of Box. I think of it this way: "Box" as we know it is software-as-a-service. It offers a web app, mobile apps, and all the trimmings. Box Platform is the platform layer upon which the SaaS is built, providing API-based management of users/content/comments/collaborations/etc. With Box Platform you have a walled garden in which you can build apps that leverage all the features of the APIs, but are not otherwise "Box apps."
I'm basically thinking about building an app that would use Box to store data of users that would subscribe to our service. Our service would allow each user to access and view their data.
This is an appropriate use case. With Box Platform you will be the owner and administrator of a Box enterprise and all the accounts and data contained within.
If I have an account that basically owns the data of all the subscribed users, can I use the enterprise access token as a base for authentication while using the user account token to restrict the user to only viewing the data from their specific sub directory. Or do I have to have a unique account with its own api key for every user?
I think it's generally cleanest to create unique accounts for each user as opposed to giving users a special subdirectory in the admin account. From there you can use the App Auth workflow to get an access token specific to that user.
