OAuth : Script to Automate Token Request

[Ram117]

Experts,

I am working on an integration between servicenow and another case management application. I am setting up OAuth integration. I am successful in setting up with  Grant type as JWT Bearer token. Now I need to do it with Grant type as password.

I did the initial OAuth Configurations in servicenow and is successful in setting up the REST message which successfully gives me Access Code.

I am having trouble in Automating this via script. 

 var payload = {

    "grant_type": gs.getProperty('x_1234_sf.sdc_oauth_grant_type').toString(),
    "username": gs.getProperty('x_1234_sf.sdc_oauth_user').toString(),
    "password": gs.getProperty('x_1234_sf.sdc_oauth_user_pwd').toString(),
    "client_id": gs.getProperty('x_1234_sf.sdc_client_id').toString(),
    "client_secret": gs.getProperty('x_1234_sf.sdc_client_secret').toString()

};

Need to pass this payload into the rest message

try {

	var r = new sn_ws.RESTMessageV2();
	r.setHttpMethod("POST");
	r.setEndpoint(gs.getProperty('x_1234_sf.sdc_oauth_end_point'));
	r.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");

	r.setRequestBody(< how do I formulate the request body ?? >);


	this.response = r.executeAsync();
	this.response.waitForResponse(5);
	this.httpResponseStatus = this.response.getStatusCode();
	this.responseBody = this.response.getBody();
	var obj = JSON.parse(this.responseBody);

	this.result = {

	"resp_code": this.httpResponseStatus,
	"a_token": obj['access_token'],
	"type_token": obj['token_type']

	};

Please provide some guidance.

thx

ram.

Hi,

I could see you are using the system property in scope 1234

from background script are you running this from global scope or your custom scope

I think it is not allowing the RestMessage call from UI action. It is telling to use async business rule

Can you inform what that UI action is doing? Can you move the code to async BR based on some condition

From UI action of an incident , am inserting the record into staging table . A business rule on the staging table ( After Insert ), makes the first call to get access token . Once I get the access token, I make a REST call (executeAsync) to third party end point.

And Application log errors as below,

[Ram117]

If I look at the Outbound HTTP logs,  i see the response status is -1, response time is 0 ms.

Is there a way to add a 'waitforresponse' to the request ?

[Ram117]

If I conver the biz rule to an Async , it all works.

If I convert this into Async business rule, i wouldnt be able to show the end user the message with the Case ID generated on the target case system.

Any way to do this ?

Hi Ram,

that's correct. one workaround for this would be below

1) I assume you must be storing the Target Case system in some field

2) next time when user opens the record/form you can show the message

Another approach

1) Put the code to trigger REST Message in script action

2) create event in event table and trigger event from BR; once event is processed it would make the API Call

3) in after insert/update BR you can trigger the event and show the message as well; it won't contain the case number but a generic message you can give that

"Case creation has been initiated. Please visit this record in some time to check the case number"

Script of BR:

gs.addInfoMessage('Your Message Here');

gs.eventQueue('event_name', current, '','');
