1.  You need to have an Azure account and create an instance of the Form Recognizer service.
2. From that resource, you'll extract the key that will be used in the site property OcpApimSubscriptionKey_FormRecognizerAPI from the Azure Cognitive Services Connector
3. Create a Storage Account in Azure in which you will create a new container and upload your documents (forms or receipts)
4. From this Storage Account you get the Blob Service SAS URL. This URL will be set in the only mandatory field for theTrainCustomModel server action 
5. If you created a file for the documents inside the container you'll need to set the boolean parameter IncludeSubFolders as True
6. The TrainCustomModel server action is in the Azure Cognitive Services Connector
7. From this action, you'll get the ModelId that will be used to retrieve results from the server action GetAnalyzeFormData 

Hello Rui.

I'm trying to use the OutSystems.AI Document Processor Reactive.

The Source field did not appear in the TrainCustomModel server action's properties. The Request field did.

I have set the Request field with the value of Blob Service SAS URL, got an error: "Syntax error caused by unexpected ':' in expression".

Then I tried to use the URL without the "https://" part, and also got an error: "Expecting an expression instead of end of line".

Please help.

 Hi Michal,

To get the Blob Service SAS URL you must have the Storage account resource already created.

When you access the detail screen for the Storage account resource you'll have a menu bar on the left side as the following image: 

You then click on the highlighted menu item and you'll find a button saying Generate SAS and connection string. I recommend you to explore some of Azure documentation if you find that you're stuck while creating the necessary resources.
