How do I integrate asp.net Custom WebHook API with Azure Logic App

Manoj Singh 41

Hi,

I'm implementing C# WebAPI for custom WebHook to integrate with LogicApp workflow. WebAPI is having action which will send message to serviebus queue, this message is been picked-up by azure function and will process the same and send response to queue. Once the response is received webhook will send the confirmation to the initial requestor.

I've developed all the pieces but not sure how do I integrate/bring them together as flow using logic apps.

Any help is appreciated.

Hi @Manoj Singh ,

Welcome to Microsoft Q&A Platform. Thank you for the question.

You can integrate all the steps like flow where you can use trigger point based on your requirement, if you want schedule based then use Schedular or else you can use the Request/Response or any other trigger. Then in next step call your API and here I assume you already tested it. Next step when message arrived in queue then using the function process it and here you can call the function inside logic app with require input. Here I am assuming you are sending the response to queue using function only. Then next step check the status of function, if it was succeeded then send a response to your initial HTTP request.

Flow:

Hi @Kamlesh Kumar , Thanks for your response. But I'm looking for Http WebHook (wait and respond to events) implementation for the problem definition. Like the one described below and how we implement using this "wait and respond" feature of webhook in the scenario I described above.

Hi @Manoj Singh -- Thanks for confirmation. In this case you can use the built-in expression called listCallbackUrl() here.

I tried to create a same scenario and please find the below screenshot for your reference,

Publisher logic app

Consumer end -- In your case it'll the custom API that you created. For demo I have added the delay in my scenario to assume your task will take time to complete the process.

Hope this will help you to achieve your scenario.

Hi @Kamlesh Kumar , thanks for your response. If you could please provide some more information on "CallbackURL", "listCallbackUrl" and "Subscribe URI" like what their purpose is and if there is any correlation with each-other and what kind operation they do?

more information on "listCallbackUrl" and their purpose is:

As part of your request body, you have to include a CallBackURL and in LogicApp there is a built-in expression called listCallbackUrl() which will include the URL that our consumer can use to call this logic app back with a response.

more information on "CallbackURL" and their purpose is:

If you see the subscribe - Body message, we have there "CallBackURL" parameter and I used the same input for my consumer. And in "CallBackURL" i am passing the value of URL where consumer need to send the response to Publisher LogicApp.

more information on "Subscribe URI" and their purpose is:

Here, in Subscribe – Method I selected POST and then provided the consumer’s HTTP Request URL as our Subscribe – URI and then included my message Body. So basically it is an endpoint URL where to send the subscription request.

You can read and understand more about HTTPWebhook trigger and how to automated event-based workflows by using HTTP webhooks. Hope this would help you.

@Kamlesh Kumar , thanks for your response.
Just to understand better, both the logic-apps(publisher, consumer) will run in parallel and when consumer logic app is invoked with a http POST request and when the flow reaches to HTTP action, it will invoke publisher logic-app(url) to process and send the response back to consumer logic-app, right? Or I'm missing something in end-end flow here or not able to visualize the working flow?

@Manoj Singh -- Yes you are right, Both the LogicApps will run parallel and your understanding is correct.
Please let me know if you have any query on this.

@Kamlesh Kumar , how can we make the publisher wait for the process to complete and then send the response back to consumer?

For example, consumer performs some time-consuming operating on the request and once done it updates the status of the record. And the publisher who was waiting for the status update(for the record) will then notify the caller(consumer) that the long-running process is over.

Could you please help me understand how do we achieve this flow? as this is what I'm not quite clear on.
