Before you beginRole required: web_service_admin, activity_admin, activity_creator About this taskTo create and use a REST web service workflow activity: Create a REST message if an appropriate one is not already configured. Assign the web_service_admin role to any user who must create or edit a custom REST activity. Determine an application, or scope, for this activity. Determine the REST endpoint to use for the activity. Use this value to override the endpoint configured in the REST message. Optionally, create basic authentication credentials. Use this value to override the credentials configured in the SOAP message. Procedure Create a custom activity. This action creates a custom activity using a template. After setting up general properties and creating input variables, configure the REST web service Execution Command: OptionDescription Map the input variables Use the variables you created to configure the command that Orchestration executes. REST message Name of an existing REST message to use in this activity. REST message function REST message function to use for this activity. Endpoint Endpoint URL for the REST web service this activity uses. Enter an endpoint in this field to override the endpoint configured in the REST message. Click the lock to open the input field. Variable substitutions Name-value pairs to pass to the REST endpoint. You can create these parameters manually, or drag input variables into the parameter fields, and then assign a value. Parameters defined in the REST message that use ${} can be assigned data from this activity template. Use the Additional attribute column to configure the system to not escape the text. By default the text sent to the REST message is escaped. If the users have provided variables using variable substitution in the REST message, then the Name column is automatically populated. Additional Headers Additional HTTP header parameters for the REST message selected. You can also use these values to override parameters inherited from the REST message. Additional Query Parameters Additional query parameters for the REST message selected. You can also use these values to override parameters inherited from the REST message. Use MID Server Check box that determines if a MID Server should be used to invoke the REST web service.Note: If the REST web service message function defines a MID Server, that MID Server is used instead of the one selected here. Required MID Server capabilities MID Server with the appropriate capabilities for connecting to the REST endpoint. By default, the system selects a MID Server with REST capabilities. This field is available when the Use MID Server check box is selected. Timeout Allowed duration of the REST web service request before it times out, in seconds. The default is 10. Authentication Determines what type of authentication is required for the endpoint. The options are: Use existing credentials in REST message: Uses credential definitions from the REST message definition. Override with Basic Authentication credentials: Uses basic authentication credentials to override the credentials in the REST message definition. Basic authentication credentials must be provisioned before they are available for selection. Override with Certificate Authentication credentials: Uses a certificate, such as a private key, to override the credentials in the REST message definition. Override with Both Basic and Certificate Authentication credentials: Uses both basic authentication and certificate authentication to override the credentials in the REST message definition. Override with OAuth Authentication credentials: Uses OAuth 2.0 credentials to override the credentials in the REST message definition. The REST message selected for this activity must have its Authentication type set to OAuth 2.0 and its OAuth profile configured appropriately. Credentials Required REST endpoint basic authentication credentials. This field is available when Override with Basic Authentication credentials is selected in the Authentication field. Only basic authentication credentials appear in the selection list, which includes credentials stored on the instance and credential IDs from an external storage system. If you are using credentials stored in a CyberArk safe, you can override the default safe defined in the MID Server configuration file. See Configure the MID Server for CyberArk for details. Add the name of a different safe as a prefix to the credential ID, separated by a colon. For example, newsafe:orch-test-f5. Protocol Profile Certificate authentication to use. This field is available when the selections in the Authentication are either Override with Certificate Authentication credentials or Override with Both Basic and Certificate Authentication credentials. OAuth profile Profile for the OAuth provider for this REST message. See Specify an OAuth profile for more information. Note: You can map parameter values in a test payload to variables in the Outputs tab automatically. See automap output variables. What to do nextFinish creating your Rest web service activity by creating output variables, creating a parsing rule, or creating template conditions. Refer to the create custom activities topic to know your template options. Auto-map REST activity output variables The ServiceNow activity designer allows you to map parameter values in a REST test payload to variables in the Outputs stage automatically. Before you beginRole required: web_service_admin, activity_admin, activity_creator About this task Note: You can test input variables from any stage in the activity designer if you have provided enough information for Orchestration to contact the endpoint and return data. Typically, the Execution Command stage is the point at which your inputs are ready for testing. Procedure In the activity designer, proceed to the Execution Command stage. Define an appropriate MID Server, if requested. The test fails if the MID Server cannot be found or if it cannot connect to the target. Click Test Activity to test the input parameters. If you added actual values for the parameters and fields, the system runs those values against the specified target and returns the resulting payload. If you mapped input variables to fields and parameters, the system displays a dialog box for assigning test values to those variables. Provide test values, if requested, and click OK to display the payload. The entire payload appears in the Raw Output tab of the Response form. Select one of these auto-mapping options. Auto-Map to Local: Directly maps values to a local variable for use within the activity. Auto-Map to Output: Directly maps values to the output variable to pass to other activities in the workflow. Auto-mapping to an output variable creates an array of objects, each of which contains the column names from the query result. REST template execution parameters You use execution parameters to create the input process script in the Pre Processing form of the activity designer. For descriptions of the REST web service command fields, see Configure the REST execution command.Note: You must use the executionParam. prefix with all variables in this table. Table 1. REST template execution parameters Name Variable Type Usage Web service message web_service_message Reference The sys_id of the corresponding web service message. Web service message function web_service_message_function Reference The sys_id of the REST message function. Web service endpoint web_service_endpoint String URL of the REST endpoint. Parameters parameters Array of JavaScript objects Array of JavaScript objects, expressed with the executionParam. prefix. For instructions on creating arrays using this parameter see Create a JavaScript array in a REST template. Use mid server use_mid_server Boolean Selects whether or not to use the MID Server. A value of true uses the MID Server, and a value of false does not use the MID Server. MidCapabilities midCapabilities String (comma separated) List of references to required MID Server capabilities. Time out time-out String Allowable time out duration, expressed in seconds. ValueCapabilities valueCapabilities Array of hashmap Capability values used to select the MID Server. For more information, see MID Server capabilities. Use this example to customize the MID Server selection if there are additional capabilities that are assigned by value:var valueCapability = {'NEW_MID_CAPABIILTY':'NEW_MID_CAPABILITY_VALUE'}; executionParam.valueCapabilities.push(valueCapability); Auth Type auth-type Boolean Type of credentials to use. The choices are: basic_auth_pick_credentials use_existing_credentials Credentials credentials Reference Contains the credentials to use for this REST message when the auth_type selected is basic_auth_pick_credentials. Create a JavaScript array in a REST template These are instructions for creating JavaScript arrays using REST execution parameters. Before you beginRole required: web_service_admin, activity_admin, activity_creator About this task To add more name-value pairs to the parameter's array, append the values to the existing array. Procedure Create a JavaScript object with the following syntax, and add it to the executionParam.parameter array: var newParameter = {"name":"parameterName","value":"parameterValue","additional_attribute":"none"}; executionParam.parameters.push(newParameter); By adding the new parameter JavaScript object to the array, you ensure that any elements already available in the array are not impacted. Make sure to set the value in the Additional attribute column in the REST message parameters input field to Do not escape text. In this case, the system does not escape the value specified for the value attribute. An example of this is: var newParameter = {"name":"parameterName","value":"parameterValue","additional_attribute":"do_not_escape_text"}; executionParam.parameters.push(newParameter); Note: If the value for the additional_attribute field is None, then the system escapes the value specified by the value attribute. In the first example, parameterValue is escaped. REST template post-processing parameters Use these parameters to create a post-processing script. Table 2. Activity designer post-processing parameters Name Variable Type Usage Status code status_code Integer Contains the status code returned from the REST web service. Header header Hashmap of JavaScript object Hashmap of key value pairs associated with the header values passed into the web service. You can access each value with executionResult.header[keyName]. Body body String Contains a string value representing the output from the REST message Error error String Returns the error string from the REST web service, unless there are no errors, in which case it returnsnull. Configure the REST execution command Use the input variables you created to configure the command that Orchestration executes on the REST endpoint. Before you beginCreate the input variables you need in the Inputs form before you can advance to the Execution Command stage.Role required: web_service_admin, activity_admin, activity_creatorNote: You can test the REST connection between the MID Server and the endpoint without having to run the acvitity in a workflow context. For details, see test template outputs. Procedure Drag variables from the list of inputs and drop them into command fields. The system formats the variable in the proper syntax for the command.

OAuth profile Profile for the OAuth provider for this REST message. See Specify an OAuth profile for more information. Note: You can map parameter values in a test payload to variables in the Outputs tab automatically. See automap output variables. What to do nextFinish creating your Rest web service activity by creating output variables, creating a parsing rule, or creating template conditions. Refer to the create custom activities topic to know your template options. Auto-map REST activity output variables The ServiceNow activity designer allows you to map parameter values in a REST test payload to variables in the Outputs stage automatically. Before you beginRole required: web_service_admin, activity_admin, activity_creator About this task Note: You can test input variables from any stage in the activity designer if you have provided enough information for Orchestration to contact the endpoint and return data. Typically, the Execution Command stage is the point at which your inputs are ready for testing. Procedure In the activity designer, proceed to the Execution Command stage. Define an appropriate MID Server, if requested. The test fails if the MID Server cannot be found or if it cannot connect to the target. Click Test Activity to test the input parameters. If you added actual values for the parameters and fields, the system runs those values against the specified target and returns the resulting payload. If you mapped input variables to fields and parameters, the system displays a dialog box for assigning test values to those variables. Provide test values, if requested, and click OK to display the payload. The entire payload appears in the Raw Output tab of the Response form. Select one of these auto-mapping options. Auto-Map to Local: Directly maps values to a local variable for use within the activity. Auto-Map to Output: Directly maps values to the output variable to pass to other activities in the workflow. Auto-mapping to an output variable creates an array of objects, each of which contains the column names from the query result. REST template execution parameters You use execution parameters to create the input process script in the Pre Processing form of the activity designer. For descriptions of the REST web service command fields, see Configure the REST execution command.Note: You must use the executionParam. prefix with all variables in this table. Table 1.
