HTTP API

Introduction
The HTTP API is the most suitable method for sending data to a W3bstream project when the data publisher is a server, mobile client, or smart device as these are typically always connected and not constrained in terms of data volume or bandwidth.
Authentication
Please refer to the Client Authentication Patterns section.
Finding your Project's HTTP route
Before sending data to a specific project in W3bstream using the HTTP API, you will need to obtain the HTTP route of the project. You can find this information in W3bstream Studio on the Project's 'Events' page.
