Getting REST response as null , for the same api curl command is working properly.

[meg6]

Hi ,

I am getting the response when i use curl command    

curl -H 'Accept: application/json' -H 'Content-Type:application/json' -XGET https://someapi.example -H 'authorization:token' , for this I am getting the response.

But when i use it in javascript as following,

var r = new RESTMessage('https://someapi.example', 'get');

r.setStringParameter('token', 'token');

var response = r.execute();

var jsonString = response.getBody();  

var parser = new JSONParser();  

var parsed = parser.parse(jsonString);  

getting error as:org.mozilla.javascript.EcmaError: Cannot convert null to an object.

am i missing anything?

The response here is null.

setAuthenticationProfile('oauth2', '<pass oauth profile sys id >');

Hi Harsha,

setAuthenticationProfile('oauth2', '<pass oauth profile sys id >');

for this i should create oauth2 record in table , but where should i specify the token .I don't know what to fill in that form, mainly provider and where will token comes into picture.

I think that is for get token. can you explain me clearly

Hi Megha,

have you checked this blog ?

How to setup OAuth2 authentication for RESTMessageV2 integrations

if you want to build token based integration then you must need to create application registry and then here you can select that in oauth provider field.

Set the credentials for the REST message using an existing basic auth or OAuth 2.0 profile.

Name	Type	Description
type	String	The type of authentication profile to use. Valid values are 'basic' to use basic authentication, or 'oauth2' to use OAuth 2.0.
profileId	String	The sys_id of an authentication profile record. When using basic auth, specify the sys_id of a Basic Auth Configuration [sys_auth_profile_basic] record. When using OAuth 2.0, specify the sys_id of a OAuth Entity Profile [oauth_entity_profile] record.

RESTMessageV2 - setAuthenticationProfile(String type, String profileId)

Hi Shishir and Harsh,

I went through the   link you both suggested.To set the third party Oauth provider we should have client id and secret.In that link they have created those in different instance as Oauth for consumer, and using it in different instance as provider.

In my case I just have an API and I need to get some data, by providing token.

I have also follow the steps as they have done it for Yahoo finance in service now, but its not working.

And my first script also

var r = new RESTMessage('https://someapi.example', 'get');

r.setStringParameter('token', 'token');

var response = r.execute();

var jsonString = response.getBody();  

var parser = new JSONParser();  

var parsed = parser.parse(jsonString);  

getting error as:org.mozilla.javascript.EcmaError: Cannot convert null to an object.

am i missing anything?

The response here is null.

Is the script incorrect?

Is there a way that i can use curl command directly?
