I have just completed Blackboard Learn REST APIs integration/LTI tool in my project. In my development environment, I have an AWS Blackboard Learn for REST and LTI Developers. I have received an "Application Id" from developer.blackboard.com website after registering my application by proving Application Name, Description and Domain. I used the received Application Id to enable REST APIs Integrations in my AWS Blackboard Learn instance.
My question here is do I have to provide the same Application Id I received for my tool from developer.blackboard.com to all the universities who want to use the tool? I am asking this because in case of Canvas integration there are separate developer keys for each instance of Canvas and the tool is using a separate key/secret to authenticate in OAuth 2.0.
