This example demonstrates how to use a script include to provide a response. By using a script include you can reuse common code and maintain readability in the REST service scripts. This example demonstrates how to parse a POST message with a string body and send a response based on the request. This example demonstrates how to parse a POST message with a binary body and send a response based on the request.
This example demonstrates how to respond with a not acceptable error. Use this error type when the request Accept header value is not supported by the web service. This example demonstrates how to respond with a bad request error. Use this error type to indicate a mistake in the request syntax. This example demonstrates how to respond with a conflict error. Use this error type in the event of multiple conflicting requests, such as multiple updates to the same record.
This example demonstrates how to respond with a not found error. Use this error type if the requested resource does not exist or is unavailable.
This example demonstrates how to respond with an unsupported media type error. Use this error type to indicate that the Content-Type of the request is unsupported. This example demonstrates how to respond with a generic service error.
The ServiceError object allows you to define the status code, message, and error detail. Use a ServiceError if the predefined error types do not meet your needs. Query parameters GET example This example demonstrates how to get query parameter values from a request.
ServiceError ; myError. Table 1.The following guide will walk you through all of the steps necessary to create a series of REST activities in a custom ServiceNow workflow. When creating the Get Posts activity we had to define a REST Message that represents the various actions we want to accomplish with our endpoint. The set of functions correspond to the various HTTP verbs, e.
Note that this code has a couple of extra lines to escape the newline characters found in the blog post Body. Now we can use these scratchpad variables to create the new blog post. At this point we are very close to achieving our requirements but we have no way to pass our scratchpad variables on to the post function of our Placeholder Posts REST Message.
With these parameters defined we can now enter the following value for the Variables on our activity. This will pass our two scratchpad variables as parameters to the post REST Message Function and the constant as the userId parameter.
Now we can use the workingpostid variable elsewhere in our workflow. Note that if you do not see your new Create Post activity this is a bug in the Workflow Editor.
REST Calls from ServiceNow Workflow
Each script include defines either an object class or a function. Consider using script includes instead of global business rules because script includes are only loaded on request. Script includes have a name, description and script. They also specify whether they are active or not, and whether they can be called from a client script.
You can call existing script includes from a script. To create an entirely new script include, you can follow the format of any of the existing script includes. In the example, the name of your Script Include is 'NewInclude' and there is a single function called 'myFunction.
When you create a new script include and give it a name, the system provides you a code snippet with the class and prototype set up properly. The privacy setting for a client-callable script-include can be public or private. Most client-callable script-includes are marked private by default. The private privacy-setting means that guests who access public pages cannot access the client-callable script-include.
A private script cannot be executed by a non-logged-in user. A public privacy-setting means that the client script can be executed by non-logged-in users that create an appropriate HTTP request.
This can create a security problem if the client script provides confidential information. To provide further control over all client-callable script includes, administrators can add the property glide. This property changes the visibility of client-callable script includes by making them all public or private.
Configure the property as follows:. Change the privacy setting for a single client-callable script include by adding the isPublic function. The isPublic setting takes precedence over the glide. For example, if the property is set to false making all client-callable script-includes private, and a script sets isPublic to true, the script is public. To change the privacy for a single client-callable script include, add the following method to the script include:.
The AssessmentCreation class provides methods that administrators can use to generate assessments and surveys. The name space for Cabrillo JS attachment functions. This enables adding and viewing attachments. Cabrillo JS camera functions to provide camera access for bar code scanning. Cabrillo JS functions to provide access to the device's location services.
Cabrillo JS functions to provide native UI for selecting items from a list.
Subscribe to RSS
Cabrillo JS functions for presenting web content inside of native modals. Cabrillo JS functions for forward and backward navigation. Cabrillo JS functions to provide access to native UI elements like buttons and spinners. CatItem API enables you to create and modify service catalog items using scripts. CatalogSearch API enables you to search catalog item. CatalogItemVariable API enables you to create and modify service catalog item variables using scripts.
This class cannot be used in other scripts. Use ConnectionInfo API to get connection attribute information through the connection and credential alias.
Provides methods that enable the creation of a large number of cost plan records for demands and projects using batch processing. Use the DataBuilder class to create a series of data points for a metric. Provides methods for checking the health of your domain configuration for the instance. The DynamicTranslation API provides methods that translate text, in real time, into multiple languages using translation service providers.
Use FlowAPI methods to execute actions, flows, or subflows in server-side scripts using either blocking or non-blocking methods.
GlideAggregate enables you to easily create database aggregation queries. The GlideAjax class enables a client script to call server-side code in a script include. The GlideappCalculationHelper API is a scriptable object that provides methods that add items to an existing request or request the recalculation of the price of a request. Provides methods that return the currency code and original currency from an associated GlideCurrencyParser. The scoped GlideDate class provides methods for performing operations on GlideDate objects, such as instantiating GlideDate objects or working with GlideDate fields.
The scoped GlideDuration class provides methods for working with spans of time or durations. The GlideElement API provides a number of convenient script methods for dealing with fields and their values. GlideElement methods are available for the fields of the current GlideRecord. Scoped GlideElement methods are available for the fields of the current GlideRecord. The scoped GlideEmailOutbound class implements the email object for scoped applications. You can use the GlideEmailOutbound methods with the email global object available in mail scripts.Cloud providers are the clouds that you can connect to.
Each provider has many products, each of which provide resource types. Each resource type maps to a single CI type. This resource type is one of the most common cloud resources that you can create.
Interfaces define operationsalso called methodsand the parameters that each method requires. Interfaces are reusable. The APIs include the actual code that the system executes. The overrides are scoped only for this API. The overrides do not override anything in other APIs.
In this example, the Microsoft. Compute product is contained in the Azure provider. Azure uses the Microsoft.
Outbound REST web service
Compute product for virtual machines. In your instance, the Microsoft. Compute product maps to the Microsoft. The Compute interface contains definitions for methods like CreateNodewhich defines how to create the actual virtual machine. Of the many parameters that CreateNode uses, Location captures the datacenter where the virtual machine resides.
Compute product and the structure defined in the Compute interface. The implementation of the CreateNode method calls the azure-compute The script includes make the actual calls to the Azure API.
A resource block represents a single cloud resource, such as a virtual server, virtual server storage, or a datacenter. You put many resource blocks together in a blueprint, which appears as a catalog item also called a stack to your users in the Cloud Catalog.
For Cloud Managementall cloud-related CI types are based on the Virtual Machine Object CI class, which provides all the attributes that you need for all the cloud resources supported by default. If a CI type for a cloud resource does not exist in the base systemyou must create a new CI class and add the necessary attributes.
This image illustrates how the components work together when a user provisions a resource from the Cloud User Portal :. You can also create more script includes to extend these base classes and create your own classes. Familiarize yourself with these base classes and the methods available within them. CAPI contains these components:.
Providers Cloud providers are the clouds that you can connect to. It is through the script includes that the connection to the cloud provider occurs. You can also modify existing script includes on method mappers if necessary. However, many of the default APIs that come with the Cloud Management application do not use modifiable script includes.
The connections are hard-coded in Java. CAPI integrates these components in your instance: Cloud Management resource blocks A resource block represents a single cloud resource, such as a virtual server, virtual server storage, or a datacenter.
In the system, each resource block is like a container that references CAPI, and links responses from the cloud provider to a specific CI. Resource blocks use: Operational steps that call CAPI for each operation, such as the provision operation, and pass along necessary parameter values that the cloud provider needs to execute the operation.
