At the moment, I am having to routinely manually upload a file onto a Teams Channel.
I have managed to create a pipeline to upload the file into my Azure Data Lake. I would now like to push the file from my Azure environment to my Teams Channel. I have found that webhooks cannot work with files and that bots can send files in the chat but not "Upload" them into a channel.
Is there a way to upload files from Azure to MS Teams using Data Factory or other alternatives?
Thank you.
The most appropriate way to partially achieve this would be to use a Teams Adaptive Card Connector but I couldn't find any way to easily set it up. It seems quite complex. Second option would be to use a Teams Post Message Connector from Azure Logic App but unfortunately it might not yet support attachments but you can send links to files stored elsewhere (SharePoint, Blob etc). Here's what you can try in the meantime.
In ADF:
Create a Copy Activity that will send the files to a Storage.
Create a Web Activity that will send a notification to a Logic App when the pipeline. You only need to use this as a trigger for the Logic App.
In Logic Apps:
Create an HTTP Connector that will receive the pipeline run information the files using the Azure Storage Blob Create blob action.
After that, create a Microsoft Teams Post a message (V3) Teams Connector, choose your Team and Channel
Use the Get blob content using path action to get a URL to the file - you might need to construct this URL.
Create your message using variables from the above connector and parse a link to the file to be downloaded.
Depending on the content of the file, you could also try to retrieve partial content and display it in the message body directly (if you can consider that an alternative for you).
I've not tried using the Adaptive Card Connector but I know it does give you a far richer dynamic experience. You would need to spend some time to design a custom card solution. Use this playground to see if it's something you can explore in the future.
The flow is as follows and kinda runs in parallel:
ADF Pipeline runs > ADF Copy Activity saves file in Blob storage
ADF Pipeline runs > ADF Web Activity triggers Logic App HTTP Connector > Logic App retrieves file from Blob storage > Sends a message to a Teams channel with a link to the file.
Here are all the supported Teams Actions.

Previously we made logic app in azure where we used http request to retrieve xml file from our clients system.
It goes like that:
HTTP request --> response body is xml data --> we save that xml data in azure blob storage as xml file.
My question is how and if its possible to do the same thing in azure data factory?
Reason for us to move this process over to data factory is that we also need to execute sql server stored procedures there and in logic app there is that 2 minute timeout and some of our procedures run longer than 2 min.
If you're looking for a way to manually trigger an Azure Data Factory pipeline,
You can manually run your pipeline by using one of the following methods:
.NET SDK
Azure PowerShell module
REST API
Python SDK
The following sample command shows you how to run your pipeline by using the REST API manually:
POST
https://management.azure.com/subscriptions/mySubId/resourceGroups/myResourceGroup/providers/Microsoft.DataFactory/factories/myDataFactory/pipelines/copyPipeline/createRun?api-version=2017-03-01-preview
More information: Manual execution (on-demand) with JSON
There are more questions to be answered, however, like "can we increase the timeout for the Logic App" (yes, see HTTP request limits - Timeout duration), "does the Logic App need to wait for the Stored Procedures to complete" and "is Data Factory the best tool for the job". The best answer to your question depends on the answer to all of these questions.
Based on the information you provided, running the logic in a different way like a Logic App on an Integrated Service Environment or an Azure Function feels like the best option.
Is it possible to use some ready made construct in azure cloud environment to ingest the events (in json format) that are currently stored in azure blob storage and have it submit those events directly to azure event hub without writing any (however small) custom code? In other words, I would like to use configuration driven approach only.
Sure. You can try to use Azure Logic Apps to realize your needs without any code or just with some function expressions, please refer to the offical documents of Azure Logic Apps to know more details.
The logic flow is as the figure below.
You can refer to my sample below to make it works.
Here is my sample to receive an event from my EventHub and transfer to Azure Blob Storage to create a new blob for storing the event data.
Create an Azure Logic App instance on Azure portal, it should be easy for you.
Move to the tab Logic app designer to configure the logic flow.
Click Save and Run buttons. Then, use ServiceBusExplorer (downloaded from https://github.com/paolosalvatori/ServiceBusExplorer/releases) to send event message and check whether new blob created using AzureStorageExplorer. It works fine after a few minutes.
I have some Excel files stored in SharePoint online. I want copy files stored in SharePoint folders to Azure Blob storage.
To achieve this, I am creating a new pipeline in Azure Data factory using Azure Portal. What are possible ways to copy files from SharePoint to Azure blob store using Azure Data Factory pipelines?
I have looked at all linked services types in Azure data factory pipeline but couldn't find any suitable type to connect to SharePoint.
Rather than directly accessing the file in SharePoint from Data Factory, you might have to use an intermediate technology and have Data Factory call that. You have a few of options:
Use a Logic App to move the file
Use an Azure Function
Use a custom activity and write your own C# to copy the file.
To call a Logic App from ADF, you use a web activity.
You can directly call an Azure Function now.
We can create a linked service of type 'File system' by providing the directory URL as 'Host' value. To authenticate the user, provide username and password/AKV details.
Note: Use Self-hosted IR
You can use the logic app to fetch data from Sharepoint and load it to azure blob storage and now you can use azure data factory to fetch data from blob even we can set an event trigger so that if any file comes into blob container the azure pipeline will automatically trigger.
You can use Power Automate (https://make.powerautomate.com/) to do this task automatically:
Create an Automated cloud flow trigger whenever a new file is dropped in a SharePoint
Use any mentioned trigger as per your requirement and fill in the SharePoint details
Add an action to create a blob and fill in the details as per your use case
By using this you will be pasting all the SharePoint details to the BLOB without even using ADF.
My previous answer was true at the time, but in the last few years, Microsoft has published guidance on how to copy documents from a SharePoint library. You can copy file from SharePoint Online by using Web activity to authenticate and grab access token from SPO, then passing to subsequent Copy activity to copy data with HTTP connector as source.
I ran into some issues with large files and Logic Apps. It turned out there were some extremely large files to be copied from that SharePoint library. SharePoint has a default limit of 100 MB buffer size, and the Get File Content action doesn’t natively support chunking.
I successfully pulled the files with the web activity and copy activity. But I found the SharePoint permissions configuration to be a bit tricky. I blogged my process here.
You can use a binary dataset if you just want to copy the full file rather than read the data.
If my file is located at https://mytenant.sharepoint.com/sites/site1/libraryname/folder1/folder2/folder3/myfile.CSV, the URL I need to retrieve the file is https://mytenant.sharepoint.com/sites/site1/libraryname/folder1/folder2/folder3/myfile.CSV')/$value.
Be careful about when you get your auth token. Your auth token is valid for 1 hour. If you copy a bunch of files sequentially, and it takes longer than that, you might get a timeout error.
so I'm new to Azure and I need to create a service that when given an office365 email (subscriber) will Automatically move files attached to new mails
of the subscriber to VM on azure and then run some tests on them there (inside the VM).
The only way I found to implement it so far is creating a logic-app for each subscriber which is done manualy.
Any help would be appreciated!
Few things if you want to get started.
Create the logic app that stores attachments to the database when a new email is received for a specific user
Add some parameters to your logic app so user email/credentials/tenant are not hard coded.
https://blog.mexia.com.au/preparing-azure-logic-apps-for-cicd
Create an ARM Template to deploy this logic app.
Create another logic app that will deploy the previous logic app.
Whenever a new user is created, call the second logic.
Also do you really need to store your files in a database ? As an alternative you can use Azure Blob Storage to store all these files.
EDIT
If you need to move the files to a VM, I would suggest you to do this:
When you receive an email
Store the attachments in Blob storage.
Generate a SAS Token (with Read permission)
Put the URL + Sas Token of your file into aan Azure Servicebus Queue.
On the VM, Have a service that reads messages from the queue and download files.
I want to write the output of pipeline to an FTP folder. ADF seems to support on-premises file but not FTP folder.
How can I write the output in text format to an FTP folder?
Unfortunately FTP Servers are not a supported data store for ADF as of right now. Therefore there is no OOTB way to interact with an FTP Server for either reading or writing.
However, you can use a custom activity to make it possible, but it will require some custom development to make this happen. A fellow Cloud Solution Architect within MS put together a blog post that talks about how he did it for one of his customers. Please take a look at the following:
https://blogs.msdn.microsoft.com/cloud_solution_architect/2016/07/02/creating-ftp-data-movement-activity-for-azure-data-factory-pipeline/
I hope that this helps.
Upon thinking about it you might be able to achieve what you want in a mildly convoluted way by writing the output to a Azure Blob storage account and then either
1) manually: downloading and pushing the file to the "FTP" site from the Blob storage account or
2) automatically: using Azure CLI to pull the file locally and then push it to the "FTP" site with a batch or shell script as appropriate
As a lighter weight approach to custom activities (certainly the better option for heavy work).
You may wish to consider using azure functions to write to ftp (note there is a time out when using a consumption plan - not in other plans, so it will depend on how big the files are).
https://learn.microsoft.com/en-us/azure/azure-functions/functions-create-storage-blob-triggered-function
You could instruct data factory to write to a intermediary blob storage.
And use blob storage triggers in azure functions to upload them as soon as they appear in blob storage.
Or alternatively, write to blob storage. And then use a timer in logic apps to upload from blob storage to ftp. Logic Apps hide a tremendous amount of power behind there friendly exterior.
You can write a Logic app that will pick your file up from Azure storage and send it to an FTP site. Then call the Logic App using a Data Factory Web Activity.
Make sure you do some error handling in your Logic app to return 400 if the ftp fails.
