Q

What benefits does IntegrationHub provide for developers?

A
  • Automates application logic to interact with external platforms
  • Enables SMEs (Subject Matter Experts) to develop and share integration actions developers can leverage in custom applications
  • Provides natural-language descriptions of integration logic in an application to help non-technical users author flows and understand what flows do.

Q

What is a spoke in the context of IntegrationHub?

A

A spoke is a logical grouping of related actions, subflows, and supporting application files.
A spoke is a scoped application that includes Flow Designer or IntegrationHub actions or subflows.
Process designers can reuse spoke logic in their own applications.
Their are default included spokes and customers spokes available to download or create.

Q

How do you create a spoke?
What’s an important thing to remember when creating a spoke here?

A

You create a spoke in the same way that you would create a scoped application - using studio.

  • It’s convention to add the word Spoke to the application name to identify an application as a spoke.

Q

What is an Endpoint URL?

A

A URL by which a REST API is accessed.

———————————————————————

17
Q

What type of data makes up query parameters?

A

Name:Value Pairs

———————————————————————

18
Q

What is an inline connection in IntegrationHub and when should it be used / not be used?

A

An inline connection is a type of connection configuration that allows you to define connection parameters directly within a flow or action, rather than creating a separate connection record in the Connection Registry.
Inline connections are not recommended for production use. Actions should be designed so the action itself does not need to be modified directly to use. Connection and Credentials aliases should be used to connect to REST APIs in production and to separate the configuration from the action definition.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

19
Q

What is a resource path in the context of endpoint URLs?

A

A resource path is added to the Base URL to create the entirety of the endpoint URL.
An API will include a variety of different resource paths to return different information.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

20
Q

REST API calls return data in the Response Body.
How is the response body data typically formatted?

A

It is usually structured in JSON or XML format.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

21
Q

It is possible to parse a REST API call’s response body into variables that can be used elsewhere in an action or flow.
What is the general strategy to get extracted data from the response?

A
  • Review the response body to select the data to return
  • Create input and output variable in the Script step
  • — Create an input variable to pass in the Response Body from the REST step.
  • — Create output variables to return data from the response
  • Create a script to parse and map data
  • — Use the JSON.parse() method in a Script step to parse a JSON response body
  • — Map the parsed data to the output variables
  • Create action outputs for the output variables to make the data available to a flow.

NOTE: To parse XML there is a preincluded XML Parser step.

22
Q

What are Connection and Credential Aliases?

A

Pointers to a connection. A connection defines the URL or hostname to connect to a third-party platform.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

23
Q

What is the difference between an inline connection and establishing a connection with Connection and Credential Aliases?

A

An inline connection creates a connection directly in a REST step, while Connection and Credential Aliases and Connections allows you to define a connection once, then use the connection in any custom action.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

24
Q

What are some things the Connections and Credential Aliases and Connections Enables?

A
  • Connection details to be configured once for all actions that need to access that connection
  • Connection details can be updated without having to reconfigure every action
  • Multiple Connection hosts to be managed centrally

———————————————————————
📁 REST in IntegrationHub Developer Documentation

25
Q

After establishing a Connection, establishing Connection and Credential Aliases - what can be done to enable developers to only have to configure the base URL of the endpoint once?

A

Configure REST actions in a spoke to point to a Connection and Credentials Alias. Configure the Resource Path in the action’s REST step to point to the REST APIs resource.
Create actions for REST resources that point to the Connection & Credential Alias. Configure the Connection URL in a Connection record with the domain and the parts of the endpoint that are common for all resources.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

26
Q

What feature of “Connection & Credential Alias”es enables a developer to switch between hosts easily?

A

A single Connection & Credential Alias can have multiple related Connection records.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

27
Q

What roles are needed out of box to create and save Connection & Credential Aliases?

A

connection_admin or admin

———————————————————————
📁 REST in IntegrationHub Developer Documentation

28
Q

What are the steps to create a Connection & Credential Alias in Studio?

A
  • 1: Click the Create Application File link
  • 2: Select the Flow Designer category
  • 3: Select the Connection & Credential Aliases option
  • 4: Click the Create button
  • 5: Configure the Connection & Credential Alias properties

———————————————————————
📁 REST in IntegrationHub Developer Documentation

29
Q

How do you associate a Connection with a Connection & Credential Alias?

A

Use the Connections related list on a particular ‘Connection & Credential Alias’ record to create Connections associated with it.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

30
Q

What roles are needed to create and save Connections?
(Connections here is used in the context of Connection & Credential Aliases)

A

connection_admin or admin

———————————————————————
📁 REST in IntegrationHub Developer Documentation

31
Q

What are Connection records considered in terms of “type”?

A

Connection records are considered data and not considered application files.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

32
Q

In what fashion are Connections supposed to be added to an application, and what is the philosophy behind this?

A

Connections need to be manually added to an application to prevent developers from including connection details to internal computers or REST APIs.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

33
Q

What is the only type of REST API that should be added to an application?

A

Connections should only be added to an application for public REST APIs.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

34
Q

What are the steps to create a REST action that uses a Connection & Credential Alias?

A
  • Create an action
  • Add & Configure a REST step
  • Select Use Connection Alias as the Connection
  • Select Connection Alias
  • Configure the Request Details section with the Resource Path, HTTP Method, and Query Parameters

———————————————————————

35
Q

What are credentials records?

A

Authentication data used to access the REST API.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

36
Q

What is special about Credential Records in ServiceNow?

A

ServiceNow stores credential information in an encrypted field. Once a credential is entered, the credential cannot be viewed.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

37
Q

What three credential types do REST APIs use and give a brief description.

A

API Key: A unique code provided by the REST API to identify the calling application or user
Basic Authentication: A user name and password combination to authenticate to the REST API
- OAuth 2.0: An authentication provider provides a secret and uses that information to grant access to a resource.

Always check docs and choose most secure method available for each API.

———————————————————————
📁 REST in IntegrationHub Developer Documentation

38
Q

What happens when a Basic Authentication credential is used?

A

ServiceNow generates an encoded string from the user name and password, which is passed to the Authorization header as a Basic encoded-string.

———————————————————————

39
Q

What role is necessary to assign a Credential to a Connection?

A

connection_admin or admin
