Setup OAuth2 authentication for RESTMessageV2 integrations

1. Configure OAuth provider on instance 1 (OAuth Application Registry -> Create an OAuth API endpoint for external clients) Create unique provider profile name. We need to generate client ID along with Client Secret. Both can be generated by system normally. Token lifespan are optional, generated by default system policy. 2. Configure OAuth consumer on instance 2 (OAuth Application Registry -> Connect to a third party OAuth Provider) Create unique consumer profile name. (very important, script will need pass in this consumer profile name as parameter) Client ID and Client secret are the values were generated from step 1. Grant type. Value can be either "password" or "refresh_token". Suggest to use password since you won't have refresh_token info initially.

Core Concepts of Inbound REST API

Use the REST API Explorer to create and test inbound ServiceNow API requests. Path parameters are part of the endpoint URL.  Query parameters determine which records, which data, and the data format returned in the response body. The HTTP status code indicates the status of the transaction request and does not indicate any information about the returned data. The response body format is set in the headers. The REST API Explorer tests requests as the currently logged in user. The  Allow access to this table via web services  option cannot be tested in the REST API Explorer. Do not use the admin user in code integrations, create a web services only user instead. Disable web service access to tables with sensitive data unless web service access is required CORS rules add security to APIs CORS rules determine which cross-origin resources can access which methods.  CORS rules cannot be tested in the REST API Explorer.  Code samples provide script stubs for integratin...
