I have a Logic App that reads messages from an Azure Storage Queue.
If the logic app fails the message is put back on the queue.
I'd like to be able to read the CloudQueueMessage.DequeueCount in my logic app but that property does not seem to be exposed to my logic app.
It's simple to read that property in an Azure Function - but in this case I'm using a logic app.
Is there a way to read the CloudQueueMessage.DequeueCount property in a Logic App?
Yes, the DequeueCount is a property of a message, when you get a message from the queue you will get all properties.
You could get DequeueCount directly with Get Messages action from the OUTPUTS.
Or you could choose to get the value with Compose Action. After Get Messages action, add a Compose action,in the input box paste the following Expression:
body('Get_messages')?['QueueMessagesList']?['QueueMessage']?[0]?['DequeueCount']
And it will get the same value as the Outputs.
Hope this could help you, if you still have other questions,please let me know.
Unfortunately Logic apps doesn't have a connector with Azure queues, more on the Documentation . However, there is a connector that is specific to Azure Service Bus, which is also one of the Queue products offered by Azure.

I want to implement a connected OAuth app in Salesforce which should trigger push events in case some entities changed, for example an opportunity was closed.
Zapier implemented something similar
https://zapier.com/apps/salesforce/integrations/webhook
Could not find something I need which is a simple way to subscribe to entity changes using the OAuth client's token and passing a webhook endpoint. I read about apex callouts, streaming API and outbound messages.
Yeah, we solved this exact problem at Fusebit and I can help you understand the process as well.
Typically speaking here's what you need to do:
Create triggers on the Salesforce Objects you want to get updates for
Upload Apex class that will send an outgoing message to a pre-determined URL
Enable Remote Site Setting for the Domain you want to send the message to
Add in Secret Verification (or other auth method) to prevent spamming of your external URL
If you're leveraging javascript, then you can use the jsforce sdk & salesforce tooling API to push the code into the salesforce instance AFTER the Auth flow has occurred AND on Salesforce Instances that have API access enabled (typically - this is enterprise and above OR professional with API enabled).
This will be helpful for you to look through: https://jamesward.com/2014/06/30/create-webhooks-on-salesforce-com/
FYI - Zapier's webhooks implementation is actually polling every 15 minutes, instead of real-time incoming events.
In which programming language?
For consuming outbound messages you just need to be able to accept an XML message and send back "Ack" message to acknowledge receiving, otherwise SF will keep trying to resend it for 24h.
For consuming platform events / streaming API / Change Data Capture (CDC) you'll need to raise the event in SF (Platform Event you could raise from code, flow, process builder, CDC would happen automatically, you just tell it which objects it should track).
And then in client app you'd need to login to SF (SOAP or REST API), subscribe to channel (any library that supports cometd should be fine). Have you seen "EMP Connector", mentioned for example in https://trailhead.salesforce.com/en/content/learn/modules/change-data-capture/subscribe-to-events?trail_id=architect-solutions-with-the-right-api ?

I am trying to create small Azure Logic app which will have some order flows.I will get the message in service bus queue. I need to get the message in logic app and based upon the message content, I need to follow the further steps. The message will contain the order data as well. There will be conditional logic, let's suppose, if order type is "new", I need to call HTTP request where I need to pass the message data as body content in POST request.
I have create a service bus queue and in logic apps, added service bus trigger which will be called when message will be received in service bus queue(automatically).
I need to able to implement conditional logic but as i am newbie in this, i am not sure how to pass this data in condtional logic from message.
You just need to mention the condition in the block and design the flow that we require. If the condition is true I have added the HTTP action mentioning the required details. For understanding purpose I have mentioned the other condition to trigger an email.
Here the flow of my logic app
If you want to continue the flow just click Add an action in True Connector.

I am trying to create an Event using Microsoft Graph SDK, as following the document #
https://learn.microsoft.com/en-us/graph/api/user-post-events?view=graph-rest-beta&tabs=csharp
1.Created "authProvider"
2.Created GraphClient with above AuthProvider
3.Creating Event using
The event is not creating also no exception/error is throwing, Could any one help me here?
This is happening because this call is being made with same transactionId frequently. It avoids unnecessary retries on the server.
It is an optional parameter , just comment out this property and try again. It should work.
Note : This identifier specified by a client app for the server , to avoid redundant POST operations in case of client retries to create the same event and also useful when low network connectivity causes the client to time out before receiving a response from the server for the client's prior create-event request.
More info is required here, as the reply from Allen Wu stated. without any details I would focus my efforts on the authprovider piece and azure app registration piece. as the rest of the example is just sending a post request to graph api.
but what is recommended really depends on what type of application you are trying to build. eg. is it a service daemon, a web app, mobile app, desktop app, single page app, etc.
I have 5+ separate logic Apps that are called via HTTP Receive. Examples are:
GetUsers
GetLocations
GetCalls
etc.
I would like to expose the Logic Apps via API Management as individual operations on one API. Any samples online to show I can do that? Am I right to assume that I'll need a policy (url-rewrite, control flow)?
Any guidance appreciated.
You can add Logic Apps as operations on an existing API by:
Creating a new operation (by default http post for a Logic App)
Defining the request/response that your Logic App will expect you to pass to it
Go to the 'backend' element in the designer and select the 'forms based editor' from the designer.
In the editor, select 'Azure resource' and then browse to the Logic App you wish to use - the is should be an http request/response based Logic App.
Add other Operations and connect them up for each Logic App you want to use.
I've created an application using Google Web Toolkit and Google App Engine that saves objects based on user selections into a RPC Service Implementation.
It was my understanding that everytime GWT "creates" this service, the data is reinstantiated with the default values. Unfortunately it seems like when a user on one computer saves a change to the data, another user on another computer is seeing the data change on their end. Im not using a datastore or anything so why is this happening?
EDIT: After some research I am seeing that I need to use sessions to handle the delivery of the objects. However, in my RemoteServiceServlet I am calling this.getThreadLocalRequest and it's returning null. Why does this.getThreadLocalRequest() return null??
UPDATE: Answering my own questions here : ) You cannot getThreadLocalRequest() in the constructor of your Servlet. duh.
The problem was that I was calling getThreadLocalRequest() in the constructor of my servlet. Good thing to be aware of - the local request doesnt happen until the servlet is loaded.
