Module 7.2 Flashcards
This allows diverse applications to talk to each other. ServiceNow supports both inbound (provider) and outbound web service (consumer) services
HTTP based Web Services
Web services are a web based method allowing applications to connect to other software applications over a what?

Consumers
Doing this to a web services means enabling a web service user (consumer) to locate the service description
Publishing
This is who instructs the consumer how they should interact with the web service
Publisher
Consuming a 3rd party web service from ServiceNow can be accomplished by doing what?
Creating a new outbound REST message
This is who invokes/ consumes published web services
Consumer
Servicenow can invoke a _________ from multiple areas within the platform including business rules, ui actions, client scripts, workflows, and flow designer
Web service
Publishing a web service in ServiceNow that can be consumed by a 3rd party can be accomplished by creating what?
By creating a new inbound web service
This is who publishes web services for clients to invoke (consume)
Publisher
As a web service provider, the now platform supports publishing access (input and query) to its underlying table structures and their associated data via what?
Direct web services
A less direct, input only mechanism is available via web service import sets which invokes data mapping using what?
Transform maps
Scripted web services is available for developing custom web services that are executed in what?
JavaScript
The url of the data to be retrieved, updated, or deleted with a rest message
End point
What are the authentication type options for a rest message?
None, basic, or oauth 2.0
Do rest messages have applications scopes?
Yes
What are the steps to configure a web services consumer?
In studio create a new application file type of REST message
Configure the REST message
Submit
When configuring a rest message, selecting this establishes trust by exchanging secure socket layer (SSL) certificates
Use manual authentication
Are rest messages reusable in business rules, email notifications, and other server side scripts?
Yes
This is used to develop, prototype, and save outbound REST messages
Rest message form
After saving a new rest message, what becomes available?
The http methods
Http methods do not appear on the rest message form until what happens?
The record is saved for the first time
This is what is used to retrieve, update, create, and delete data at the end point
Http methods
User has to be authorized to access data with http methods (t/f)
True
When examining parameters for an endpoint, in order to understand what information a web service provider expects, you must do what?
Read the provider’s documentation and provide values for the required variables
When giving values to REST message functions the value must be enclosed with what?
${}
When providing a name value to match a variable from the endpoint api documentation. Make sure not to include what and why?
The equal sign because it will be automatically inserted at runtime
How do you give values to rest message functions?
Add variables to the http query parameters
Where do you go to configure a rest message http query parameter?
In the rest message select the http method of interest , in the http request section, scroll to the http query parameters section
Before testing a rest message function, what must be done?
The variable substitutions must be configured
There must be a variable substitution for all required http query parameters (t/f)
True
What do you select to test/post a rest message function?
Test in related links
A http status of ___ indicates that a rest message post was successful but does not mean the expected results were returned.
200
After testing a rest message, this field shows the variables passed at the end of the endpoint (you may have to increase the field size to see all parameters and values)
The parameters field
A rest message post http status of 200 indicates a connection was made but you should always check what to verify you received what was expected?
The results
Click this related link to have server side code stub generated automatically
Preview script usage
Does preview usage script extract variable values?
No; code stub posts only
Rest response can either be JSON or what?
XML
The rest response is extracted from where?
The returned data
You must understand structure of returned data in order to extract values from a rest response (t/f)
True
This script include is accessible from all application scopes. It contains methods for working with JSON data
JSON script include
Can servicenow tables be web service providers?
Yes
The “allow access to this table via web services” option is only selectable if the accessible from option value is what?
All application scopes
Application access enables/ disables web service access (t/f)
True
Creates endpoints, methods, and variables used to send REST requests to a Servicenow instance
REST API Explorer
Why shouldn’t you practice with the REST API explorer on a production instance?
The rest api interacts with records in the servicenow instance database
How do you get to the rest api explorer?
System web services> rest> rest api explorer
What is the default api in the rest api explorer?
The table api
This api from the rest api explorer allows you to query, create, update, and delete a table’s records. You cannot change the instance when exploring but can from a script.
The table api
Configure endpoint variables using what?
Query parameters
What should you select before configuring query parameters?
The database operation
For complex queries, what should you use on a table’s list to build the query?
The filter builder
After running a query from the filter builder on a table’s list, right click on the breadcrumbs and select copy query. What’s next?
Paste the query into the sysparm_query field
The query parameters depend on what?
The database operation being performed
Select this button at the bottom of the rest api explorer to test the web service
Send
Results from testing the web service in the rest api explorer appear where?
At the bottom of the form
The response from testing the web service in the rest api explorer is returned in what format?
The format specified in the configuration parameters
This creates stub code for using rest to interact with servicenow tables
