api for adding lti activities

[mgibson2]

Im looking through the api docs. Im looking for the abilitiy to add an lti activity via the api. Im reading this section in particular. https://canvas.instructure.com/doc/api/file.lti_dev_key_config.html  is that about conifgging your lti for the lms? or is that about adding lti activities to an existing course? I think its the latter. Is the former possible in the api? thanks for your help - mark
