Good Day,
Is it possible to GET data into a content set for ArcGIS online? I am new to ArcGIS online. Was wondering how I can call (GET) an endpoint in json format (with some lat and lon) to dynamically update the data set when a new object is entered.
Thank you all
Sure, you can use GET to query a Feature Service: documentation (example). To edit or add data, you'll want to use ApplyEdits - that is POST only, as you can see in the documentation.
You can do that using Rest API and many other Languages.
Here are the list of all the tutorials with different languages.
Its very helpful and well guided.
All the tutorials with Rest API : https://developers.arcgis.com/labs/?product=rest-api&topic=any

How to get this list by using ServiceNow API?
The easiest way to achieve that is by using REST API, here is how the call will look like:
https://yourinstance.service-now.com/api/now/table/sys_choice?sysparm_query=name=incident^element=category
If you are only interested in label the call will look like this:
https://yourinstance.service-now.com/api/now/table/sys_choice?sysparm_query=name=incident^element=category&sysparm_fields=label
You didn't clarify whether you're looking for client-side, server-side, or REST API, but here's the answer for server-side:
var gr = new GlideRecord('incident');
gr.get('e8caedcbc0a80164017df472f39eaed1');
gs.print(gr.category.getChoices());
This getChoices() API is a GlideElement API, so you call it on a field element in a server-side GlideRecord.
You can find this API documentation here.
I am creating Cars store in Asp.Net for my school.
I built an Api Method:
[HttpGet("api/brands/{brandName}/models")]
public IActionResult Get(string brandName)
{
{
var model = _context.getBrandByName(brandName);
return Ok(model.Models.ToList());
}
}
An it works when I am checking it with Postman.
Now I would like User to choose brandName from selection list in the website and show him avaliable models.
In other words I dont know how to use this Api to get Data displayed.
Any help will be strongly appreciated
RESTful Web services are one way of providing interoperability between computer systems on the Internet. REST-compliant Web services allow requesting systems to access and manipulate textual representations of Web resources using a uniform and predefined set of stateless operations.
from Wikipedia.
This means, the REST API's only concern is to provide the data to work in a uniform and predefined set of operations, where those operations take the HTTP Verb that was used in consideration.
in your example, your GET route, should only be api/brands/{brandName}
the default in rest api, http verbs say:
GET - getting one element or a list
POST - creating
PUT - updating
DELETE - removing
in your application, the best approach would be something like:
GET /api/brands will get ALL existing brands
GET /api/brands/<brand_name> will get just one brand
POST /api/brands will create a new brand
PUT /api/brands will edit an existing brand
DELETE /api/brands will delete an existing brand
from your question:
Now I would like User to choose brandName from selection list on the website
the website would then request a GET to the route /api/brands to get the list of all of the brands.
This is the REST API part, it concerns ONLY in providing the right data to the system that request it.
if you want to create a website in order to CONSUME this data, you can easily create a new web project in your solution and request the data that the API provides, making the Website completely "blind" from where the data comes from, as it only asks for the data itself.
Making the whole system much easier for updated and maintainability.
In other words I dont know how to use this Api to get Data displayed.
The main purpose of REST API is to expose data not to display it by using any kind of UI framework.
If you think you need to manage the full stack of your application end-to-end. I mean from User interface to your database then you must think at implementing the V of the MVC pattern bu return a view and not just a data. ASP.Net Core can help you with that. Follow this tutorial, it explains a lot about this pattern in ASP.Net Core MVC.
I am trying to build an API service for my Yii based website,
I have create an API controller with all the functions that returns objects in JSON format.
I also created a system to generate API keys for a specific URL... but I cant seem to understand how to detect the url from where the call is being made to my api so I can compare and validate.
I have tryed with HTTP_REFERER ...not working...
Any idea how is this possible ?
Thanks
try this:
Yii::app()->request->urlReferrer
or
Yii::app()->request->host
or
Yii::app()->request->hostAddress

I'm building my first Rest API which serialize data to JSON and XML formats.
I would like to provide an index page to API clients, where they would be able to choose implemented endpoints.
What information do I need to include to make my API most useful, and how should I organize it?
That's a very complex question for a simple answer.
You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.
Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

At the very top level I think quality REST API docs require at least the following:
a list of all your API endpoints (base/relative URLs)
corresponding HTTP GET/POST/... method type for each endpoint
request/response MIME-type (how to encode params and parse replies)
a sample request/response, including HTTP headers
type and format specified for all params, including those in the URL, body and headers
a brief text description and important notes
a short code snippet showing the use of the endpoint in popular web programming languages
Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.
Is there a service that will give me the driving distance between two addresses? Apparently Google Maps API requires you to display a map, which I don't want to do (on that particular page), and I'd like to just snag the data and save it to my DB after a user submits a form, rather than waiting for JS to do it's thing.
If it's relevant, this is going into a Django app. I discovered that CloudMade offers a Python API, which is nice, except their latest dev release has a bug in it (can't use the API object), but more importantly, it's support for Canada is awful (couldn't find directions from any major city around here!).
MapQuest's Directions API is HTTP Querystring based (I'm not sure if it's entirely RESTful). Can get XML or JSON response. Just need to send it an HTTP GET Request.
http://developer.mapquest.com/web/products/open/directions-service
Use the "distance" response parameter.
I don't have a high enough reputation on SO to comment on an answer but I just wanted to be clear that contrary to the voted correct answer, Google Directions API has to adhere to the Google Maps API. If you scroll down the supplied link, you will see:
Note: the Directions API may only be used in conjunction with displaying results on a Google map; using Directions data without displaying a map for which directions data was requested is prohibited. Additionally, calculation of directions generates copyrights and warnings which must be displayed to the user in some fashion. For complete details on allowed usage, consult the Maps API Terms of Service License Restrictions.
Would it be possible to use Google Maps GDirections object? This can return the textual directions instead of the map overlay if called with a div object. From there you can use the getDistance (or getDuration) functions. You can always use an invisible div for the returns if you don't want anything to be displayed on the page.
Start here
http://code.google.com/apis/maps/documentation/examples/directions-advanced.html
http://code.google.com/apis/maps/documentation/reference.html#GDirections
And use this sample code
var map;
var directionsPanel;
var directions;
function initialize() {
directionsPanel = document.getElementById("route");
directions = new GDirections(null, directionsPanel);
GEvent.addListener(directions , "load", onGDirectionsLoad);
directions.load("from: 500 Memorial Drive, Cambridge, MA to: 4 Yawkey Way, Boston, MA 02215 (Fenway Park)");
}
function onGDirectionsLoad(){
alert(directions.getDistance().html);
}
Here is my solution:
Signup for Mapquest Developer network.
Get AppId
Open your command shell and run the following command(or use fiddler) But running it through curl will give you flexibility to automate your request
curl -X POST -H "Content-Type: application/json" -d '{locations: ["Salt Lake City, UT","Ogden, UT",],options: {allToAll: false}}' http://www.mapquestapi.com/directions/v2/routematrix?key=YOURKEYGOESHERE >> distance.txt
Save above command with all your destinations into batch or sh file.
Now grep and parse out your distance.txt file for what you need.
There are free services out there, but the quality of the data may be questionable/non-existent in areas. Be aware of licences on the data too, storing in your own DB may be a breach.

Take a look at Navteq. I used their service in developing a driving directions application about 5 years ago, and got good results. Can't speak for them lately though. I believe the best URL is Navteq Routing Service
You can use the new Google Directions API directly, without using any javascript.
