Tessell is an API-first architecture. Whatever you do in the GUI can also be done via APIs. Both REST APIs and Terraform APIs are available for your development.
For most of the actions in the GUI, Tessell also provides a Code Equivalent button that spits out the corresponding code in the programming language of your choice.
Terraform
You can use Terraform to create and modify many of the components within Tessell. To get started, you can either go to our provider documentation here or select the <> Code
button on the bottom right of the UI.
