SDK Reference: HTTP Trigger

The HTTP Trigger fires when an HTTP request is made to the workflow's designated endpoint. This allows you to start workflows from external systems.

http.Trigger

Creates the HTTP trigger instance.

import "github.com/smartcontractkit/cre-sdk-go/capabilities/networking/http"

httpTrigger := http.Trigger(&http.Config{
    AuthorizedKeys: []*http.AuthorizedKey{
        {
            Type: http.KeyType_KEY_TYPE_ECDSA_EVM,
            PublicKey: "0x...",
        },
    },
})

http.Config

The configuration struct for the HTTP trigger.

http.AuthorizedKey

Defines an EVM address authorized to trigger the workflow.

http.Payload

The payload passed to the callback function.

Callback Function

Your callback function for HTTP triggers must conform to this signature:

import "github.com/smartcontractkit/cre-sdk-go/capabilities/networking/http"

func onHttpTrigger(config *Config, runtime cre.Runtime, payload *http.Payload) (*YourReturnType, error)

Parameters:

• config: Your workflow's static configuration struct.
• runtime: The runtime object used to invoke capabilities.
• payload: The HTTP payload containing the request input and signing key.
