We're upgrading our API
On June 6th, 2019, Mailbox API 1.0 will be sunsetted, and at that time any apps using this legacy API will no longer work. Please use Mailbox API 2.0 instead.
We maintain two official API clients and encourage developer-built API clients as well.
Official Help Scout Clients
Open source clients for Python, Ruby, Node.js and more are listed on the open source page.
