Flux REST API

Aside from programmatically managing your Flux services via FluxMethods, Martini also allows you to manage your workflows via the Flux REST API. With this API, you can:

Execute a Flux service
Terminate a Flux service
Send an event to Flux services
Get all Flux services' contexts
Get a Flux service's context
Get a Flux state's context
Add a tag to a Flux service
Remove a Flux service's tag
Get a Flux service's definition

Flux REST API or FluxMethods?

If you are trying to handle Flux service(s) from another service, TORO recommends you use FluxMethods instead.

Headers

By default, the Flux REST API allows access to all Flux services. However, if the Flux service is secured, an Authorization request header is needed.

Header Name	Data Type	Description
Authorization	string	Bearer `<The access token of a Martini user>`

Endpoints

All endpoints of the Flux REST API have paths beginning with /flux-api. Read on below for more information about the API's endpoints.

Available as a Postman collection (v2.1)

You can use Postman to try out and call the endpoints of the Flux REST API. Simply download and import this Postman collection.
