35		-Of these four points, the last two will be discussed in separate microlearnings. In this microlearning, we will focus on the first two aspects of the configuration. As you might have noticed I did not mention the fact whether the integration is synchronous or asynchronous as a crucial part of the configuration. The reason being that when configuring a (SOAP) web service you always need to send an acknowledgment back to the client calling the web service to let them know what the status of the message is. In case you want to set up the rest of your integration asynchronously you can send an empty message back as acknowledgment. In case you want to set up the rest of your integration synchronously you need to send the response you have received from the backend operation back to the client. More on the choice between asynchronous and synchronous in a later stage.
	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.

37		-=== 3.1 Operation Name ===
	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.
38	38
39		-Let us first zoom in on the parts of the configuration before we learn how you can implement it in eMagiz. Starting with the operation name. When you have dealt with the API Gateway offering of eMagiz in the past or have some knowledge of how APIs work the notion of an operation name should not be unfamiliar. In essence, it is a unique name that defines a certain operation. In eMagiz the best practice for naming the operation is as follows:
	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:
40	40
41		-* Send{technicalnameoftheoperation}
	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/">
42	42
43		-When you are in Create you will notice that eMagiz uses the default suffix of Request and Response is added to the operation name. Therefore the full operation name a client needs to call to get the desired result if you adhere to the best practice is:
	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:
44	44
45		-* Send{technicalnameoftheoperation}Request
	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"/>
	53	+ <xs:element name="Enum" type="Enum"/>
	54	+ <xs:element name="Integer" type="xs:long"/>
	55	+ <xs:element name="Boolean" type="xs:boolean"/>
	56	+ <xs:element minOccurs="0" name="DateTime" type="xs:dateTime"/>
	57	+ </xs:sequence>
	58	+ </xs:complexType>
	59	+ <xs:simpleType name="nonEmptyString">
	60	+ <xs:restriction base="xs:string">
	61	+ <xs:minLength value="1"/>
	62	+ </xs:restriction>
	63	+ </xs:simpleType>
	64	+ <xs:simpleType name="Enum">
	65	+ <xs:restriction base="xs:string">
	66	+ <xs:enumeration value="URGENT"/>
	67	+ <xs:enumeration value="HIGH"/>

	69	+ <xs:enumeration value="LOW"/>
	70	+ <xs:enumeration value="PLANNING"/>
	71	+ </xs:restriction>
	72	+ </xs:simpleType>

47		-=== 3.2 SOAP Webservice Namespace ===
	74	+To wrap things up you need to define your Request and Response element and close the schema:
48	48
49		-The second part of the configuration is the SOAP Webservice Namespace. When hosting a SOAP Webservice via the standard eMagiz tooling you need to define a namespace. To smoothen this process eMagiz automatically generates a namespace based on the configuration settings you choose in the Design phase of eMagiz.
	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>
50	50
51		-=== 3.3 Configuration in eMagiz ===
	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.
52	52
53		-Now that we know what configurations are required, we can see how we can implement this in eMagiz. In the Capture phase, nothing changes. You simply draw a system on the canvas including at least one line that goes from the system towards eMagiz. When you are done you move to the Design phase in eMagiz. In this phase, you need to correctly set up the operation name(s) and the SOAP Webservice Namespace.

54	54
55		-The configuration in Design starts at the system level. At the system level, you need to define the technical name (or let eMagiz automatically fill it in for you) and select the checkbox called Combined Entry Connector. By selecting this checkbox you tell eMagiz that you want to host an endpoint for others to call.

62		-
63		-In this case, we opt for the SOAP web service. After you have done so eMagiz will automatically define the SOAP Webservice Name and SOAP Webservice Namespace.

67		-With this, you are done with your configuration on the system level. Don't forget to update the status of your task. Now that we have configured the system it is time to configure the integration that is drawn from the system to eMagiz. We can do so by double-clicking on it (or by accessing the context menu and selecting the edit option). When you open the Edit page on the integration level you will notice that a new segment is added (compared to other integrations). This segment defines the settings on the system level we have just specified and defines the operation name.

70		-
71		-As you can see eMagiz has already prefilled the operation name for you based on the best practice at eMagiz. If you want to change you have the option to do so. Do note that for the sake of consistency it would be smart to use the same naming convention within a single project to avoid confusion.
72		-
73		-=== 3.4 Add integration to Create ===
74		-
75		-Now that we have finished the configuration in Design the last step of this microlearning is to add the integration to Create. You can simply do so by navigating to Create -> Add integrations and selecting the integration to move it to Create. After you have selected it press Save to add the integration to Create.
