Since the API keys are deprecated, I’m looking at way to handle events from a separate system using an AWS Lambda function and call into Hubspot to create/update/delete contacts. It appears that using the OAuth authentication, I need to supply a redirect URL which requires user interaction. Is this correct? I don’t see how that would work. ---

Ok, I created a ‘Private App’ and basically store the Private App’s Access Key in AWS Secrets. That seems to work for getting a list of contacts. Are there any limitations with Private Apps?
