Implement this Solution

Analyze Results Logic App - send single-page PDF document data to REST API endpoint of trained custom document model

Next step is to open the Logic App designer in the Azure portal for the second Logic App you deployed with "analyzeresults" in the name.

1. Add the Azure Blob Storage trigger When a blob is added or modified (properties only) (V2) with the following settings:

Property	Setting
Storage account name	Use connection settings
Container	/single
Number of blobs to return	1
How often to you want to check for items	1 Minute

2. Add a new step: Create SAS URI by path (V2) with the following settings:

Property	Setting
Storage account name	Use connection settings
Blob path	List of Files Path (Dynamic Expression)

3. Add a new step: HTTP Please note that you will have to replace a few variables tailored to your resource deployment. Here are the variables you must replace:

• FORM_RECO_URI: this is the Endpoint of your Form Recognizer service in Azure. You can find your endpoint here after navigating to your Form Recognizer service that was created during resource deployment.

• FORM_RECO_KEY: this is the Key used to access your Cognitive Service API. You can find your Key here after navigating to your Form Recognizer service that was created during resource deployment.

• MODEL_ID: this is the Model ID that you created while training a custom document model in Form Recognizer Studio.

Property	Setting
Method	POST
URI	<FORM_RECO_URI>/formrecognizer/documentModels/<MODEL_ID>:analyze?api-version= 2022-01-30-preview
Headers	Ocp-Apim-Subscription-Key <FORM_RECO_KEY>
Body	{"urlSource": "@{body('Create_SAS_URI_by_path_(V2)')?['WebUrl']}"}

4. Add a new step: Initialize variable with the following settings:

Property	Setting
Name	analyze-status
Type	String
Value	@{null}

5. Add a new step: Until with the following settings

Property
analyze-status
is equal to
succeeded

6. Add an action: HTTP with the following settings

Property	Setting
Method	GET
URI	@{outputs('HTTP')['headers']['Operation-Location']}
Headers	Ocp-Apim-Subscription-Key <FORM_RECO_KEY>

7. Add an action: Set variable

Property	Setting
Name	analyze-status
Value	@{body('HTTP_2')['status']}

8. Add an action: Delay

Property	Setting
Count	10
Unit	Second

9. Add a new step: Create blob (V2)

Property	Setting
Storage account name	Use connection settings
Folder path	/results
Blob name	@{replace(triggerBody()?['DisplayName'], '.pdf', '.json')}
Blob content	@body('HTTP_2')

10. Click Save. Your Logic App should now look like this:
