My Service Bus queue is receiving telemetry of 2 different objects. For Object1 is have to send mail to MailId1 and for Object2 j have to send mail to MailId2. Also, I have to use some of the content from JSON telemetry as the body of my mail.
For a single object, it is working fine. In my logic app, I have used service bus (its queue is receiving telemetry messages) followed by parse JSON (to parse content as JSON) and lastly SMTP to send mail. In case I need to make decisions based on JSON, what workflow can I use in LogicApp?
I have used Condition action as shown in the image below.
JSON parsed in IF condition is
{
"properties": {
"dbt": {
"type": "integer"
},
"latitude": {
"type": "number"
},
"location": {
"type": "string"
},
"longitude": {
"type": "number"
},
"owner": {
"type": "string"
},
"speed": {
"type": "integer"
},
"stdb": {
"type": "integer"
},
"timeCreated": {
"type": "integer"
}
},
"type": "object"
}
JSON parsed in ELSE condition
{
"properties": {
"message": {
"type": "string"
},
"owner": {
"type": "string"
},
"timeCreated": {
"type": "integer"
}
},
"type": "object"
}
For either of the telemetry, the condition always fails and executes else part. IF part is never executed. Where am I going wrong in setting condition for IF part?
Any help would be appropriated.
You can use conditional statements.

Here is my Scenario,
There will be a drop of csv file into blob storage every day ,that will be processed by my dataflow in ADF and generate a csv in output folder.
Now Using logic apps, I need to send that csv file (less than 10 mb ) as an attachement to customer via Outlook connector.
Besides ,My body of the email must have dynamic value coming from that blob csv .
For example 'AppWorks' is the column value in column 'Works/not'. Sometimes it may be "AppNotWorks".So How to handle this scenario in Azure logic apps
You can use the combination of both data factory and logic apps to do this. Use look up activity to get the first row of the file (Since the entire column value will be same, we can get the required value from one row).
Now use web activity to trigger the logic app. Pass the logic app's HTTP request URL to web activity. In the body, pass the following dynamic content:
#activity('Lookup1').output.firstRow
When you debug the pipeline, the logic app will be successfully triggered. I have given the Request Body JSON schema to get values individually. For the sample I have taken, it would look as shown below:
{
"properties": {
"customer": {
"type": "string"
},
"id": {
"type": "string"
}
},
"type": "object"
}
Create a connection to storage account to link the required file.
Now, using the Outlook connector, send the Email.
The following is the entire Logic app JSON:

The following is the resulting Mail image for reference:
My question is in regard to API schemas in Azure API Management, resource type Microsoft.ApiManagement/service/apis/schemas.
A schema created through the Azure Portal is created with the content type application/vnd.oai.openapi.components+json and written to document/components/schemas, which is the correct path for schema definitions in an OpenAPI definition.
Sample:
{
"value": [
{
"id": "/subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.ApiManagement/service/xxx/apis/xxx/schemas/1629566051926",
"type": "Microsoft.ApiManagement/service/apis/schemas",
"name": "1629566051926",
"properties": {
"contentType": "application/vnd.oai.openapi.components+json",
"document": {
"components": {
"schemas": {
"patch-components-id-request-1": {
"type": "object",
"properties": {
"name": {
"type": "string"
},
"description": {
"type": "string"
},
"documentationURL": {
"type": "string"
},
"iacURL": {
"type": "string"
},
"duration": {
"type": "integer"
},
"statusID": {
"type": "integer"
},
"owner": {
"type": "string"
}
}
}
}
}
}
}
}
],
"count": 1
}
A schema created through the REST API or the Go SDK is set using properties.document.definitions, which leads to it being written to document/definitions, no matter the contentType.
Sample:
{
"value": [
{
"id": "/subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.ApiManagement/service/xxx/apis/marble-dev-fctn/schemas/marbleschemas",
"type": "Microsoft.ApiManagement/service/apis/schemas",
"name": "marbleschemas",
"properties": {
"contentType": "application/vnd.oai.openapi.components+json",
"document": {
"definitions": {
"patch-components-id-request-1": {
"type": "object",
"properties": {
"name": {
"type": "string"
},
"description": {
"type": "string"
},
"documentationURL": {
"type": "string"
},
"iacURL": {
"type": "string"
},
"duration": {
"type": "integer"
},
"statusID": {
"type": "integer"
},
"owner": {
"type": "string"
}
}
}
}
}
}
}
],
"count": 1
}
When setting the contentType to application/vnd.ms-azure-apim.swagger.definitions+json this is fine, but when setting the contentType to application/vnd.oai.openapi.components+json two problems arise: The definition will not be included when exporting the OpenAPI Schema (at least when exporting from the Azure Portal, i have not tried any other way), since definitions is not a valid OpenAPI field, and it will not be shown in the Developer Portal.
As far as i understand it the definitons would need to be written to document/components/schemas for application/vnd.oai.openapi.components+json and document/definitions for application/vnd.ms-azure-apim.swagger.definitions+json.
I can import the definition to the correct path by setting it manually in an ARM Template or REST API call, but i am working on getting the terraform resource to work correctly, which is relying on the Go SDK. There might be a workaround for that as well but i would really like to find out if my understanding is wrong or if there might be a problem here.
How do I get the subject property from the payload below ?
I've got an http-triggered logic app:
I want to be able to grab the contents of the subject property.
The schema as shown above in the image looks like this:

]
}
}
How do I get the subject property from this payload?
Go to your logic app designer in the azure portal and you can specifically assign the json to variables in your flow process
Here is the link on how to do this
With the Request trigger, if you want to get the property, you need pass the Request Body into json cause the triggerBody() value is in a String type, it doesn't support select the property. Set the parse json action like the below pic.
Then your json set the data in array type, that's another problem you will encounter. So when you select property you need add the index like the below with Expression: body('Parse_JSON')[0]['subject'].
I test with short json two properties subject and topic.
I was trying to add JSON schema validation with in a Logic App using ParseJSON action.
I want to validate the existence of either of the object in the message (equivalent to XSD choice).
For instance, messages may have either of lastname or familyname.
{
"name": "Alan",
"familyname": "Turing"
}
Or
{
"name": "Alan",
"lastname": "Turing"
}
I modified the generated schema as,
{
"type": "object",
"properties": {
"name": {
"type": "string"
},
"oneOf": [
{
"lastname": {
"type": "string"
}
},
{
"familyname": {
"type": "string"
}
}
]
}
}
Logic App execution throws below error
Just to test if any other schema combination keywords works, tried to test with anyOf in place of oneOf and it fails in execution as well.
Does Logic Apps support these extended validation ? Am I missing some specific syntax here ?
If you are validating that either familyname or lastname be present then you are missing the "required" attribute.
{
"type": "object",
"properties": {
"name": {
"type": "string"
}
},
"oneOf": [
{
"familyname": {
"type": "string"
},
"required": [ "familyname" ]
},
{
"lastname": {
"type": "string"
},
"required": [ "lastname" ]
}
]
}
This will validate the JSON. If you want to get the values out in a later step you could use the coalesce function.
#coalesce(actionBody('Parse_JSON')?['familyname'], actionBody('Parse_JSON')?['lastname'])
I have logic app that is triggered by a service bus. The message content is not usable as it is just random characters. I suspect that perhaps it needs to be parsed but it is not clear how to do this.
I have the following:
Not enough reputation to add an image - but screen shot from Azure
"Insert_Entity": {
"inputs": {
"body": {
"PartitionKey": "deviceID",
"RowKey": "#variables('curDate')",
"content": "#triggerBody()?['ContentData']"
},
When I look at the data that I am getting for the "content" coming from the "#triggerBody()?['ContentData']" it looks like this:
"W3sidHlwZSI6ImxvZyJ9LF...." I deleted most of this as it 100's of characters long.
I suspect that this needs to be parsed or something to look at the actual message body. I have checked this out but don't know where to insert code like this: Getting content from service bus in logic apps
Can you please explain how to see the message body.
Can you please explain how to see the message body.
The string W3sidHlwZSI6ImxvZyJ9LF.... you mentioned is base64string. If we want to see the message body we need to convert the base64string to string
We could do that with base64ToString(triggerBody()?['ContentData']) details please refer to the screenshot.
Body info:
After getting the value as Tom Sun solution, i had had to extract the json part of the result to be able to parse it, Logic App Expression :
substring(
variables('result'),sub(indexOf(variables('result'),'{'),1),
sub(lastIndexOf(variables('result'),'}'),indexOf(variables('result'),'{'))
)
Then use Parse JSON function to parse the result using the schema :
{
"properties": {
"data": {
"type": "string" // Change As Required
},
"dataVersion": {
"type": "string"
},
"eventTime": {
"type": "string"
},
"eventType": {
"type": "string"
},
"id": {
"type": "string"
},
"metadataVersion": {
"type": "string"
},
"subject": {
"type": "string"
},
"topic": {
"type": "string"
}
},
"type": "object"
}
