How can I base64 encode a client ID and client secret in the Application Registry?

[Popat420]

Hi all,

I have setup an Application Registry record in ServiceNow along with Connection and Credential Alias. 

But for this specific integration it is required the client id and client secret are base64 encoded, so how can I do this please? Can this be done via the Oauth API script field option in the app registry record?

When I test with Postman I use the base64 encoded client id secret in the Authorisation header,

Thanks in advance.

I understand, but that is possible with what Jaspal suggested.

Use something like this in a script. 

var base64Val = gs.base64Encode(clientId + ':' + clientSecret);

And use that in the Auth header.

How is the Rest call triggered? If it's in a script, you could do this directly, or in a flow (action), use a script step, and use this as output.

Thanks @Community Alums Im not sure I understood Jaspals Suggestion. Could you explain please? Where do I use the above script and where can I define the auth header in ServiceNow?

Hi @Popat420,

That depends, how are you triggering your REST call?

I am inline with @Jaspal Singh  solution.

Hi @Dr Atul - LNG can you please explain to me what solution Jaspal has provided because I think I am not understanding clearly. The forum he has linked talks about using credentials username and password instead of base64 encoded ?
