I have out form one of the tasks in Logic App:
{
"headers": {
"Connection": "close",
"Content-Type": "application/json"
},
"body": {
"systemAlertId": "....",
"endTimeUtc": null,
"entities": [
{
"$id": "us_1",
"hostName": "...",
"azureID": "someID",
"type": "host"
},
{
"$id": "us_2",
"address": "fwdedwedwedwed",
"location": {
"countryCode": "",
},
"type": "ip"
},
],
}
}
I need initialize some variable named resourceID that contains value someID which is read from above example.
Value someID will always be found in the first member of Entities array, in that case I guess need to use function first
Any idea how expression of Initial variable should look?
Thanks
Considering the mentioned data you are receiving from Http trigger, I have used Parse JSON in order to get the inner values of the mentioned JSON. Here is how you can do it.
and now you can initialize the resourceID using 'Initialise variable' connector and set its value to azureID as per your requirement.
Have a look at the Parse JSON action.
To reference or access properties in JavaScript Object Notation (JSON) content, you can create user-friendly fields or tokens for those properties by using the Parse JSON action. That way, you can select those properties from the dynamic content list when you specify inputs for your logic app. For this action, you can either provide a JSON schema or generate a JSON schema from your sample JSON content or payload.
With the information in the JSON available in an object, you can more easily access it.

I am building a Azure Logic App which recieves a webhook. I need to parse the body and validate if a array contains any object with a property that matches either of two values, but have no idea how to do it.
Any ideas?
The JSON i am recieving in the webhook is like below, shortened for brevity. I am looking at the components-array:
{
"id": "12601",
"components": [
{
"id": "10021",
"name": "Value1"
},
{
"id": "10022",
"name": "Value2"
},
{
"id": "10023",
"name": "Value3"
}
]
}
From this array I need to output a parameter true/false if any properties with name == "Value1" or "Value" appears.
Is there any syntax similar to LINQ in C#, or do you use a foreach? I have not been able to find any simple way like:
If(Arr.Any(x => x.name == "Value1"))
Perhaps you can use Parse Json to parse the Json string you received, and then use condition to determine whether the name contains value1.
Please refer to my logic app:
I need to write REST API in Node jS for JSON to JSON transfromation.
There are many library and I sort listed "JSONata"
Please find JSONata simple sample here
The challenge is API receive JSON which has data and map but JSONata require map value without quotes.
{
"data" : {
"title" : "title1",
"description": "description1",
"blog": "This is a blog.",
"date": "11/4/2013"
},
"map" : {
"name": "title",
"info": "description",
"data" : {
"text": "blog",
"date": "date"
}
}
}
but the map object expected by JSONata is like below.
{
"name": title,
"info": description,
"some" : {
"text": blog,
"date": date
}
}
The above JSON key is in Quotes and value without Quotes.
Please find the NodeJS API code.
app.post('/JSONTransform', function(req, res, next)
{
const data = req.body.data;
const map = req.body.map;
var expression = jsonata(map);
var result = expression.evaluate(data);
res.send(result);
});
I can write simple function to remove quotes but the above map is simple example. It can be any no of child object and may have some special character in the value including quotes.
I prefer some npm library or standard way to remove quotes or configure JSONata to accepts quotes in value.
Appreciate if you suggest any other library or option.
This Node JS API is called from ASP.NET Core Web API.
ASP.NET Core Web API gets the data and map from database and pass this as single JSON to Node JS API.
Please suggestion solution to this problem or best alternative.
Thanks
Raj
I found solution to this problem.
Pass the single JSON that has both data and map. Since MAP is not valid JSON, I made entire map as string and escaped doubles quotes which is inside the string.
Please find the sample.
{
"map": "{ \"name\": title, \"info\": description, \"data\": { \"text\": blog, \"date\": date }}",
"data": {
"title": "title1",
"description": "description1",
"blog": "This is a blog.",
"date": "11/4/2013"
}
}
How do I extract the content of my request that's been received inside of the logic app?
I've got a regular http-triggered logic app, like so:
I'm sending it a POST request through postman like so:
{
"$content-type": "application/octet-stream",
"$content": "<?xml version=\"1.0\" encoding=\"UTF-8\"?><cases><file-path>yes</file-path></cases>"
}
I'm attempting to extract the $content payload:
"#{string(xml(string(triggerBody()?['content'])))}"
The issue I am getting is:
How do I extract the content of my request that's been received inside of the logic app?
Here's the entire initialize variable step:
"Initialize_variable": {
"inputs": {
"variables": [
{
"name": "contentOfRequest",
"type": "String",
"value": "#{string(xml(string(triggerBody()?['content'])))}"
}
]
},
"runAfter": {},
"type": "InitializeVariable"
}
Cause the request body is string, it doesn't support select property. so you need parse it Json format firstly, then you will be able to select $content.
About how to get the Json Schema, just click the Use sample payload to generate schema in the Parse Json action and paste your Json data, then click the done.
And then extract the $content value with body('Parse_JSON')?['$content'], in this way you will get the content value.
I have a backend API (that implements ApiController) which I'd like to put behind an APIM API. ApiController allows us to discriminate between two different GET operations based on the query parameters that are passed in. When I attempt to define these endpoints in APIM, I get the following error:
The message suggests an endpoint is defined solely by the path and operation. But that seems to contradict documentation I found here which suggests there's a way to differentiate between operations based on query parameters:
Required parameters across both path and query must have unique names.
(In OpenAPI a parameter name only needs to be unique within a
location, for example path, query, header. However, in API Management
we allow operations to be discriminated by both path and query
parameters (which OpenAPI doesn't support). That's why we require
parameter names to be unique within the entire URL template.)
I have an ApiController that defines two different Get operations, differing only by the query parameters. How do I represent that in my APIM API?
The problem comes from multiple operation objects with the same OperationId. This is invalid swagger. In the Swagger file did not match the name of the selected API, so change the title attribute of the doc tag to match the destination API it worked..
Here is a similar SO thread you could refer to.
I got my answer from Azure support, sharing the info here:
APIM endpoints are defined by the path, method, and the name you assign to the operation. To differentiate between two GET endpoints to the same controller, differing only by query parameters, you need to hardcode required query parameters into the path. See the following two images:
In the latter image, the hardcoded query parameter is classified by the UI as a template parameter, but it still behaves like a regular query parameter. Query arguments defined in this way:
Are required
Can appear in anywhere in a request's list of query arguments
Are not case-sensitive
Are listed as a "Request Parameter" along side all other path parameters and query arguments in the Development Portal
Edit:
There's a typo in the screenshots. The URLs are case sensitive, and the casing of "blah" were different in each case. Here's what the the Open API Specification looks like when the casing is consistent. The overloaded path (with the query parameter hardcoded into the path template) appears in a section called x-ms-paths:
{
"swagger": "2.0",
"info": {
"title": "Echo API",
"version": "1.0"
},

I have a simple Azure Logic App with the following components:
Recurrence
HTTP Get from HTTPS url
I've tried to configure the next component to save the HTTP response body to OneDrive with OneDrive Connector configured as follows:
FilePath: ApiTest/test.json
Content: #{body('http')}
Content Transfer Encoding: None
This gives the following error:
{"code":"InvalidTemplate","message":"Unable to process template language expressions in action 'microsoftonedriveconnector' inputs at line '1' and column '11': 'Template language expression cannot be evaluated: one of string interpolation segment value has unsupported type 'Object'. Please convert the value to string using the 'string()' function.'."}
If I then use #{string(body('http'))} I get:
{"code":"InvalidTemplate","message":"Unable to process template language expressions in action 'microsoftonedriveconnector' inputs at line '1' and column '11': 'The template language function 'string' was invoked with an invalid parameter. The value cannot be converted to the target type.'."}
How can I use the body of HTTP Connector and save it to One Drive?
I don't have an answer, but I am wrestling with this very issue right now. I will post if I find a solution and would be very interested in case any one else finds a solution. I do find one thing interesting. There is a header and body option on the consuming end of my Http Connector which works when it runs. The error (as the above poster notes) occurs when passing that value to the next card. But, when I look at the output (link) on the run tab, I see a json value for the header and for the body. Does this need to be wrapped in a json parser?
This works for me just fine and generated the file in the /random/test.txt folder, however I believe the problem in your case is that you are downloading a JSON file which is causing it to be interpreted as an object by the engine.
I'll follow up with the team and maybe we need a "ToJson" call, or a way to "Passthrough", or make "String" more "flexible" (though that could be weird).
"fileContent": {
"Content": "#{body('http')}",
"ContentTransferEncoding": "None"
},
Actions in code view looks like:
"http": {
"type": "Http",
"inputs": {
"method": "GET",
"uri": "http://www.carlosag.net/"
},
"conditions": []
},
"microsoftonedriveconnector": {
"type": "ApiApp",
"inputs": {
"apiVersion": "2015-01-14",
"host": {
"id": "/subscriptions/xxx/resourceGroups/zzz/providers/Microsoft.AppService/apiApps/MicrosoftOneDriveConnector",
"gateway": "https://yyy.azurewebsites.net"
},
"operation": "UploadFile",
"parameters": {
"filePath": "random/test.json",
"fileContent": {
"Content": "#{body('http')}",
"ContentTransferEncoding": "None"
},
"overwrite": true
},
"authentication": {
"type": "Raw",
"scheme": "Zumo",
"parameter": "#parameters('/subscriptions/...')"
}
},
You should try "#body('http')". I believe this will work. "#{body('http')}" is a form of string interpolation: expected output value is string and not a JSON.
I initialized a String variable 'Content' and set the value to the body of the HTTP.
#{body('HTTP')}
And then I convert the String to JSON to read the desired node with an expression.
json(variables('Content'))?['ExcelFile']
I went a step further and base64 decoded to binary in order to upload to Sharepoint. Going to OneDrive would likely be the same.
base64ToBinary(json(variables('Content'))?['ExcelFile'])
