Thanks for all the feedback here everyone.
We've been discussing a release of a new API for a while now, and will definitely be making some new functionality available in the coming month. We plan to release a totally new API in 2019 which will have dedicated functionality for content delivery. We will also be exposing more powerful webhooks and project management endpoints we have available on our internal API.
Let us know if you'd like to learn more, and we'll keep you updated on our progress here 🙌
