We are using Rest API via PowerShell (Invoke-RestMethod), in order to insert records in ServiceNow event [em_event] table with a single call, using the web service API.
We successfully inserting events to the em_event table,
but the only problem is with the additional_info field.
For some reason,
The JSON structure of my PowerShell script,
Is causing the output of additional_info, to return as an Object and Not as JSON string.
And as a result,
The values in additional_info not showing properly, but instead as [object Object]:
This is the JSON structure in my PowerShell script:
# Specify request body
$body = #"
{ "records":
[
{
"source":"MyClass",
"event_class":"$AtargetResourceType",
"resource":"$AtargetResourceType",
"node":"$AtargetResourceName",
"metric_name":"$Aname",
"type":"$AsignalType",
"severity":"$Aseverity",
"message_key":"$Aid",
"u_mc_object":"$AtargetResource",
"description":"$Adescription",
"additional_info":"{
'u_mc_object_class':'$AsourceCreatedId',
'u_mc_parameter':'$AmetricName',
'u_mc_parameter_value':'$AmetricValue'
}"
}
]
}
"#
image which you have posted is not opening. but according to your issue below line will return string value for additional_info:
($body|ConvertFrom-Json).records.additional_info
I had the same issue sending the request using Postman, I was sending the request like this:
{ "records":
[
{
"source":"BMC TrueSight",
"type":"Incident from trusight",
"severity":"1",
"description":"This is a test from WEB SERVICE API ERROR",
"additional_info":{
"status":"new",
"description":"This is a descriotion from additional information",
"category":"41",
"subcategory": "test",
"company": "test",
"business_service":"test"
}
}
]
}
and it showed [object][object] in the additional information field, what I did was sent that field as a string like this:
"additional_info": "{\"assignee_group\":\"ETSS\/UNIX99\",\"status\":\"new\",\"description\":\"This is a descriotion from additional information\",\"category\":\"41\",\"subcategory\":\"test\",\"company\":\"test\",\"business_service\":\"
}
You only need to convert the JSON into a string.

Here is my db.json :
{
"users": [
{
"id": "1"
"name": "John"
}
]
}
I'd like to be able to update the user id by sending a PUT request on the existing user. But the following does not work:
Request URL :
PUT /users/1
with body:
{
"id": "2"
"name": "John"
}
Is there a way to update an object id?
If you are using PUT request means ,the request URL should be like this "PUT/users/1" .
Refer below mentioned image.
I'm using postman to send put request
This does not seem to be possible, as said in documentation:
Id values are not mutable. Any id value in the body of your PUT or
PATCH request will be ignored. Only a value set in a POST request will
be respected, but only if not already taken.
I am using the new query parameters API https://msdn.microsoft.com/en-us/library/mt845781.aspx
I am able to call parameters fine, however when trying to set them I get an error message. After parsing the error I get this
VERBOSE: POST https://api.powerbi.com/v1.0/myorg/groups/e7229a42-46ef-4d80-b8ca-e42909509dbb/datasets/5ef116d7-917... with -1-byte payload
error : #{code=InvalidRequest; message=Dataset Parameters list is invalid in 5ef116d7-9179-40a2-8a30-a657265dfe4a. Reason: Empty;
target=5ef116d7-9179-40a2-8a30-a657265dfe4a}
I don't understand because the parameters list is not empty? I have created a physical table with the parameters and tried and then also created a list of values in the manage parameters settings and it still gives the same error.
PowerShell -
$parametername = "YourData"
$parametervalue = "Company1"
#POST body
$postParams = #{
"name" = "$parametername"
"newValue" = "$parametervalue"
}
JSON from documentation (I am not including updatedetails in PowerShell because I don't know how)
"updateDetails": [
{
"name": "MaxId",
"newValue": "5678"
},
{
"name": "StrParam",
"newValue": "Another Hello"
}
]
}
You can find the solution here
You just need to enable the Load for the parameters
I'm using ADFv2 to transfer some data. As a part of this operation I need some configuration values to pass into the pipeline.
The config values must be pulled at runtime from a REST service - not as parameters.
I can successfully query the REST service with Web Activity and I can see the output in the debug view.
Now the problem :)
How do I use this output in other activities further in the pipeline?
My Web Activity configuration is like this:
{
"name": "Web1",
"type": "WebActivity",
"policy": {
"timeout": "7.00:00:00",
"retry": 0,
"retryIntervalInSeconds": 30,
"secureOutput": false
},
"typeProperties": {
"url": "https://myazurefunction.azurewebsites.net/api/MyFunction",
"method": "GET",
"headers": {
"Content-Type": "application/json"
}
}
I have tried to access the output after is has executed, but it seems empty:
#activity('Web1').Output
#activity('Web1').output
#string(activity('Web1').Output)
they are all empty. Any suggestions?
Thanks!
I set up an ADF2 and try to get a response.
This works for me:
#string(activity('Post').output)
Have you checked the output in the debugging?
Here is my output:
{
"test": {
"value": 123,
"text": abc
},
"concat": 123abc
}
I use the stored procedure to insert the values into the destination table on a Logical Server.
In ADFv2, you access the output of previous activities using #activity('ActivityName').output.
For the web activity defined, the response from your function should be in JSON format, so you would reference specific JSON values using their attribute names in the response. For example, your defined web activity, named Web1, calls a function that returns a response of:
{
"foo": "bar",
"some": "value"
}
To use the value of foo in a subsequent ADF activity, you would reference #activity('Web1').output.foo. ADFv2 provides multiple type conversion functions, should you need the returned value converted to another type.
If your function is returning an empty JSON response back, you may want to inspect the response from your function using Postman or another tool to ensure you are returning a properly formatted response, and that your function isn't failing for another reason.
Inside your Azure function code, you should be returning a JSON object, along with a success code, similar to return req.CreateResponse(HttpStatusCode.OK, json);.
Also note that if you reference a property of the response and it does not exist, ADF will fail at that point, so you can use an If Condition activity to check for the required values to better handle failures in ADFv2.
I am able to retrieve records for a particular Incident ID using Invoke-RestMethod. However, while retrieving the data, values like Resolved To, Updated By, etc. get populated by a sysid.
Resolved By comes in this format:
https<!>://devinstance.servicenow.com/api/sysid, value= sysid
I would like to view the username instead of the sysid.
The 'User ID' (user_name) isn't on the Incident, it's on the sys_user table, so you'll have to dot-walk to it.
If you're using the table API, you'll need to specify a dot-walked field to return, using the sysparm_fields query parameter.
This is no problem, just specify your endpoint like this:
$uri = "https://YOUR_INSTANCE.service-now.com/api/now/table/incident?sysparm_query=number%3DINC0000001&sysparm_fields=resolved_by.user_name"
I've specified a query for a specific incident number is requested, but you can replace that with whatever your query is.The important part is sysparm_fields=resolved_by.user_name. You'll want to specify any other fields you need here, as well.
The JSON I get as a result of running this API call, is the following:
{
"result": [
{
"resolved_by.user_name": "admin"
}
]
}
Note the element name: "resolved_by.user_name".
Another option for doing this, would be to tell the API to return both display, and actual values by specifying the sysparm_display_value parameter and setting it to all to return both sys_id and display value, or just true to return only display values.
Your URI would then look like this:
https://dev12567.service-now.com/api/now/table/incident?sysparm_query=resolved_byISNOTEMPTY%5Enumber%3DINC0000001&sysparm_display_value=all
And your JSON would contain the following:
"number": {
"display_value": "INC0000001",
"value": "INC0000001"
},
"resolved_by": {
"display_value": "System Administrator",
"link": "https://YOUR_INSTANCE.service-now.com/api/now/table/sys_user/6816f79cc0a8016401c5a33be04be441",
"value": "6816f79cc0a8016401c5a33be04be441"
},
"sys_updated_by": {
"display_value": "admin",
"value": "admin"
},
This would be accessed by:
answer.result[n].resolved_by.display_value
I have setup a content type with a subject field that has pre assigned values in a dropdown field.
I am using the services api to post new content from a polymer app.
When I POST to the api I send the field structure and value in json but get and error.
"406 (Not Acceptable : An illegal choice has been detected. Please contact the site administrator.)"
Even though the object I am sending matches one of the required values in the field.
Do I need to prefix the value with something? I assume I'm posting to the right place to get that response but don't know why it would accept anything other than the string value.
Here is what I sent to the api which is picked up by my Charles proxy.
{
"node": {
"type": "case",
"title": "my case",
"language": "und",
"field_subject": {
"und": {
"0": {
"value": "subject1"
}
}
},
"body": {
"und": {
"0": {
"value": "my details of subject"
}
}
}
}
}
And here is an example of what I have setup in my Drupal field
subject1| first
subject2| second
subject3| third
subject4| forth
For anyone else with the same problem, this subject is poorly documented, but the answer is simple, my subject did not need the value key despite devel suggesting thats how it would be formatted.
"field_subject": {
"und": [
"subject1"
]
}
I could also shorten my code with "und" being an array.
