Usage info
Open a modal with a user by exchanging a trigger_id received from another interaction. See the modals documentation to learn how to obtain triggers from interactive components.
Within the view object, you can pass an external_id if you wish to use your own identifiers for views. The external_id should be a unique identifier of the view, determined by you. It must be unique for all views on a team, and it has a max length of 255 characters.
Response
Assuming your view object was properly formatted, valid, and the trigger_id was viable, you will receive a success response.
If you call views.open on an already opened view you will receive a 200 response.
