Installation

Installation for this package should be straight forward.

go get github.com/0x19/sift-golang

Once it's installed you can import it as

import (
	"github.com/0x19/sift-golang"
)

Usage

Bellow you can find few examples on how to use sift-golang.

Track an event

Here's an example that sends a $transaction event to sift.

package main

import (
	"log"

	"github.com/0x19/sift-golang"
)

func main() {
	s := sift.New("your_api_key")

	// Name of the event. Can be pre-defined such as $transaction and custom
	// such as "my_custom_event"
	eventName := "$transaction"

	data := map[string]interface{}{
		"$user_id":          "someone@someone.com",
		"$transaction_id":   "1233456",
		"$currency_code":    "USD",
		"$amount":           15230000,
		"$time":             1327604222,
		"trip_time":         930,
		"distance_traveled": 5.26,
		"$order_id":         "ORDER-123124124",
	}

	extras := map[string]interface{}{
		"return_action": true,
	}

	r, err := s.Track(eventName, data, extras)
	if err != nil {
		log.Fatal(err)
	}

	log.Printf("Got tracking record: %v", r)
}

Label a user as good or bad

package main

import (
	"log"

	"github.com/0x19/sift-golang"
)

func main() {
	s := sift.New("your_api_key")

	record, err := s.Label("some-user-id", map[string]interface{}{
		"$is_bad":      true,
		"$reasons":     []string{"$chargeback", "$fraud"},
		"$description": "Some description about this user...",
	})

	if err != nil {
		log.Fatal(err)
	}

	log.Printf("Got label record: %v", record)
}

Remove label from user

package main

import (
	"log"

	"github.com/0x19/sift-golang"
)

func main() {
	s := sift.New("your_api_key")

	response, err := s.UnLabel("some-user-id")

	if err != nil {
		log.Fatal(err)
	}

	log.Printf("Got un-label response: %v", response)
}

Get user's score

package main

import (
	"log"

	"github.com/0x19/sift-golang"
)

func main() {
	s := sift.New("your_api_key")

	record, err := s.Score("some-user-id")

	if err != nil {
		log.Fatal(err)
	}

	log.Printf("Got score response: %v", record.Score)
}
