If I just have an accessible end point of an Web Service, is there a way to find out all the APIs exposed by that?
Considering the api to be WCF Rest, If help is enabled, you can see all the operations exposed by the endpoint by browsing to endpoint/help.

I want to connect to Essbase from a 3rd Party App - Alteryx. Essbase exposes JAVA APIs and allows 3rd party apps to connect to those JAVA APIs. However, Alteryx cannot connect to those APIs and hence I am interested in knowing about the SOAP based Essbase Webservices.
Does anyone know how to call Essbase Authentication webservice complete with attributes such as URL and request body.
In case if anyone has a working sample that can be shared, please post it or otherwise, kindly point to a web resource that can be referred to fulfill this requirement.
I would recommend against using the SOAP-based Essbase web services. They are a dead end with almost zero documentation. You can just use the normal Essbase Java API, which can be configured to use HTTP. There are numerous examples on the web as well as sample Java examples that ship with Essbase.
can someone help me telling what is RESTful and difference with `web Service'?
i tried to search but i get confused between it and web service can anyone help ?
It's name clearly state its meaning that services provided on the web are called a web service
web service has two type REST API and SOAP API
RESTful Web Services are basically REST Architecture based Web Services. In REST Architecture everything is a resource. RESTful web services are light weight, highly scalable and maintainable and are very commonly used to create APIs for web-based applications.
SOAP (Simple Object Access Protocol) is a messaging protocol that allows programs that run on disparate operating systems (such as Windows and Linux) to communicate using Hypertext Transfer Protocol (HTTP) and its Extensible Markup Language (XML).
RESTful is one kind of web service. Another kind is SOAP. I think comment in this link will help you

I have searched a lot upon internet but still i didn't get the clear difference between web services and web APIs? Somewhere I read that all web services are API's but all API' are not web services. How?
What all I know is both allow to utilize the functionality of other applications.Can someone describe me clear difference?
I have been on the same journey to learn the differnce between Web API (not JUST API) vs Web Services.
First, we know for a fact that both use the Web as the communication tool as stated by #Kris.
While looking at these 2 videos, both serve as the "middleman" (the waiter in the restaurant) for a client to ask a Web Server to process and deliver a response.
Web Service (From 0:35)
API (In general) (From 1:12)
When I was looking for an actual differnce between the two, usually most articles and videos go on an unrelated comparison between "Web Services vs API" as they exclude the "Web" out of "Web API".
See this article, for example, which contains the title "Web API Vs Web Service...." yet, contain sub-titles like:
"Differences of API vs Web Service"
"Pros and Cons of Web Services vs API Service"
"Web Service vs API: Fueling Both With Scraping Robot’s API"
The only difference I could find is if we were to discuss this in .NET context.
Here's a question post related to this.
To sum it up, Web Services are used in the SOAP protocal while Web API is usually created in the RESTful way. The more detailed answers are in the post but ultimatelly do not answer the main question that is asked.
Conclusion: The question raised in the public domanin has no clear definition to what is difference between the two, thus the 2 terms are ,for the most part,
interchangeable
All web services are APIs. An API is an Application Programming Interface. But there are offline APIs, which are not web services. There are APIs for all things from Office to Websites. The API is just a defined interface to be able to control/communicate with some software. Web Services just provide that means of connecting over the web.
There is more to discuss when you are talking about APIs which are communication protocols and data formats, but you get the basic idea.
An API (Application Program Interface) is the interface through which another program can communicate with a program.
A web service in this context is one of those programs with an API. 'Web' means that it is accessible via the web, mostly via HTTP. A service usually has a well defined purpose.
For instance a date web service's purpose could be to provide the current date. The API of my service would have a single 'endpoint': get the date. The service then implements this API. It somehow retrieves the date and sends it back.
I want to access the data sets on an API portal(using SSIS) which provides an Internet REST web service to expose certain functions to the third party applications.
I am relatively new to the Webservices concept. Could someone help me by providing a tutorial or step by step procedure on how to access the datasets on this portal using HTTPS and REST services methodology ?
Also, it has some authentication parameters that needs to be included in header of the request, like AUTH_CUSTID, AUTH_KEY and AUTH_SOURCE.
Thanks in Advance!
This may or may not help you (depending on whether I understood your requirement):

We have developed web service(as well as generic handler) based web application.But it seems that the methods could be invoked by using different tools like (Poster,Advanced Rest Client) to get the secure information of Administrator and could do malicious activities.We would be grateful if you provide us the best possible method to make the method inside webservice or generic handler becomes secure.
What you actually want is to probably know more about WS-Security in your respective technology
Wikipedia: http://en.wikipedia.org/wiki/WS-Security
Microsoft: http://msdn.microsoft.com/en-us/library/ms977327.aspx
Java: https://ws.apache.org/wss4j/
The above works if you expose as SOAP web service.
For REST web service, I found this link:
