2		-When setting up a point at which your customers can talk to you eMagiz offers various methods of creating such a point. One of those options is by hosting a SOAP Webservice in eMagiz that handles XML messages asynchronously or synchronously. One last check to perform before you can communicate with the external parties that the endpoint is available to receive messages and up and running. In this microlearning, we will learn how you can perform such a check.

10		-This microlearning centers around the endpoint check.
	13	+This microlearning centers around configuring your SOAP web service.
11	11
12		-By endpoint check, we mean: determine whether the WSDL is accessible on the correct endpoint so we can forward the URL to the WSDL + the URL to call to our external parties
	15	+By configuring, we mean: Designing and determining the characteristics of the SOAP web service
13	13
14		-* The endpoint consists of the following elements:
15		- ** Starts with https:// or http://
16		- ** Second part is the host (i.e. where is the endpoint running)
17		- ** Third part is the port on which the incoming traffic is accepted
18		- ** These three things combined make up the first part of our endpoint that will vary per environment
19		- ** Following that we have a static remainder of the endpoint that is build up as follows: /{soap WS name}/{Id}/
20		- ** If you want to get to the WSDL simply add the name of the WSDL (which is defined by the Id given to the "Dynamic WSDL" support object) and the .wsdl extension to the endpoint when viewing it in the browser
	17	+Crucial parts in the configuration are:
	18	+* Operation Name
	19	+* SOAP Webservice Namespace
	20	+* Validation
	21	+* Authentication

33	33
34		-As you can see the endpoint can be divided into two parts. One part is dynamic across environments and one part is static across environments. Let us first determine how we can find out the first part of our endpoint.
	35	+Of these four points, we will zoom in on the validation part of our SOAP Webservice in this microlearning. The SOAP Webservice serves as a point of entry where people with the rights credentials (security) and the right answers (validation) are allowed to enter and perform their actions. In the next microlearning, we will talk about the security part. In this microlearning, we talk about the validation part.
35	35
36		-=== 3.1 HTTPS or HTTP ===
	37	+As you have learned from the crash course you can validate an XML message with the help of an XSD. This XSD describes dataTypes, order, associations, and length of attributes. You can use such an XSD for the validation of what your clients send you. eMagiz will automatically define a WSDL based on the XSD that you provide that stores metainformation and stores the XSD for validation purposes. This way you can communicate the WSDL (location) to external parties as a reference document upon which they can build their solution. If you keep the eMagiz defaults you can access the WSDL via http://host:port/ws/ws-name/ws-name.wsdl. Note that you need to all values (except for the ws and .wsdl part) with actual values.
37	37
38		-We start at the top with the determination of HTTPS or HTTP. A simple rule of thumb is that when running in the eMagiz Cloud the endpoint starts with https:// and when the endpoint is running locally (i.e. on-premise) the endpoint starts with http:// (unless you secure it yourself, more on that later).
	39	+What eMagiz does need from you is the correct XSD for validation. As a starting point you should download the XSD that eMagiz has generated based on the system message(s) you have defined in the Design phase. Once you have that you can structure the XSD correctly. A valid XSD start with a schema segment. In this segment you need to define your SOAP WS namespace:
39	39
40		-=== 3.2 Host ===
	41	+<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
	42	+<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
	43	+ xmlns="http://www.academy.emagiz.com/ns/mlacade-bus/spwbsrv-connector/1.0/"
	44	+ attributeFormDefault="unqualified" elementFormDefault="unqualified"
	45	+ targetNamespace="http://www.academy.emagiz.com/ns/mlacade-bus/spwbsrv-connector/1.0/">
41	41
42		-The next part of the endpoint is the host. The host is effectively the (virtual) machine on which the endpoint is running. When hosting an endpoint in the eMagiz cloud the host part is the combination between the DNS left-most label on Route level and the cloudslot on which your environment is running. The first part of the equation can be found under Deploy -> Architecture. The second part can be found under Deploy -> Properties by looking for the {technicalnameproject}.amqp01.host. You need to combine the two elements via a dash -. An example of this would then be spwbsrv-test-cloud0001.emagizcloud.com. In case of an on-premise installation, you should ask your customer what the IP address or DNS name is to connect to the machine on which your runtime is running. If the runtime is running locally on your laptop the host equals localhost.
	47	+Once you have that you need to copy all complex and simple types from the XSD that you downloaded and paste them below the lines you have created:
43	43
44		-=== 3.3 Port and Path ===
	49	+<xs:complexType name="Input">
	50	+ <xs:sequence>
	51	+ <xs:element name="String" type="nonEmptyString"/>
	52	+ <xs:element minOccurs="0" name="Decimal" type="xs:decimal"/>

46		-Whether or not the port needs to be defined to get to the endpoint is once again determined by the location. If the endpoint is hosted in the eMagiz Cloud the port is *not* part of the endpoint. However, when you host your endpoint locally the endpoint becomes part of your endpoint. Note that to make this piece work in the eMagiz Cloud you should set up your Route properly. More on that in our Cloud Management courses. You can determine the port, for the endpoint or the route, by navigating to the infra flow of the runtime through which you host your SOAP web service. In the infra flow you can also find the remainder of the path to get to the WSDL location.
	74	+To wrap things up you need to define your Request and Response element and close the schema:
47	47
48		-In the infra flow there is a support object of the type "Dynamic WSDL". In here you see the default location of the hosted SOAP endpoint, which is http://localhost:${entry.connector.ws.port}/ws/{soap WS name}/. Based on this, you can find the WSDL by adding {Id}.wsdl to the URI. In this example, when hosting the SOAP web service on-premise, a valid URI would be {{code}}http://localhost:8099/ws/soapgn3-connector/soapgn3-connector.wsdl{{/code}}.
	76	+<xs:element name="SendNptRequest">
	77	+ <xs:complexType>
	78	+ <xs:sequence>
	79	+ <xs:element name="Input" type="Input"/>
	80	+ </xs:sequence>
	81	+ </xs:complexType>
	82	+ </xs:element>
	83	+ <xs:element name="SendNptResponse">
	84	+ <xs:complexType/>
	85	+ </xs:element>
	86	+ </xs:schema>
49	49
50		-{{info}}Note that when running your web service in the eMagiz cloud, the first part (the host part) will change depending on your configuration in Deploy Architecture and the cloud slot on which you are running. An example URI, in that case, would be {{code}}https://soap-test-cloud0000.emagizcloud.com/ws/soapgn3-connector/soapgn3-connector.wsdl{{/code}}{{/info}}
	88	+Combining this will result in a valid XSD for my example. In your case, you will need to enter other values. When you are done with the creation of the XSD save it with a name such as spwbsrv-connector.xsd and upload it to the flow. After you have uploaded the XSD link it to the connector-xsd support object in your entry.
