Fingerprint Pro Server Go SDK

Fingerprint is a device intelligence platform offering 99.5% accurate visitor identification. Fingerprint Pro Server API allows you to get information about visitors and about individual events in a server environment. It can be used for data exports, decision-making, and data analysis scenarios. Server API is intended for server-side usage, it's not intended to be used from the client side, whether it's a browser or a mobile device.

This Go package is automatically generated by the Swagger Codegen project:

• API version: 3
• Package version: 7.1.0
• Build package: io.swagger.codegen.v3.generators.go.GoClientCodegen

Requirements

Go Lang 1.21 or higher

We keep the Go support policy and support the last two major versions of Go.

Installation & Usage

1. Get the package from GitHub:

go get github.com/fingerprintjs/fingerprint-pro-server-api-go-sdk/v7/sdk

2. Import and use the library:

package main

import (
	"context"
	"fmt"
	"github.com/fingerprintjs/fingerprint-pro-server-api-go-sdk/v7/sdk"
	"log"
)

func main() {
	cfg := sdk.NewConfiguration()
	client := sdk.NewAPIClient(cfg)

	// You can also use sdk.RegionUS or sdk.RegionAsia. Default one is sdk.RegionUS
	//cfg.ChangeRegion(sdk.RegionEU)

	// Configure authorization, in our case with API Key
	auth := context.WithValue(context.Background(), sdk.ContextAPIKey, sdk.APIKey{
		Key: "SECRET_API_KEY",
	})
	// Usually this data will come from your frontend app
	visitorId := "<VISITOR_ID>"
	requestId := "<REQUEST_ID>"
	opts := sdk.FingerprintApiGetVisitsOpts{
		RequestId: requestId,
	}
	visits, httpRes, err := client.FingerprintApi.GetVisits(auth, visitorId, &opts)
	fmt.Printf("%+v\n", httpRes)

	if err != nil {
		var tooManyRequestsError *sdk.TooManyRequestsError

		if errors.As(err, &tooManyRequestsError) {
			log.Fatalf("Too many requests, retry after %d seconds", tooManyRequestsError.RetryAfter())
		} else {
			// You can also use err.Model() and err.Body() to get more details about the error
			log.Printf("Error %s: %v", err.Code(), err)
			log.Fatal(err)
		}
	}

	fmt.Printf("Got response with visitorId: %s", visits.VisitorId)

	event, httpRes, err := client.FingerprintApi.GetEvent(auth, requestId)
	if err != nil {
		// You can also use err.Model() and err.Body() to get more details about the error
		log.Printf("Error %s: %v", err.Code(), err)
		log.Fatal(err)
        }

	if event.Products.Identification != nil {
		fmt.Printf("Got response with Identification: %v", event.Products.Identification)
	}
}

Note You can also check examples located in example directory. To run the examples:

cd example && FINGERPRINT_API_KEY=SECRET_API_KEY VISITOR_ID=VISITOR_ID_EXAMPLE go run getVisits.go

Alternatively, you can define your environment variables inside example/.env file and run the examples without passing them as arguments. If your subscription region is not the “Global/US” region, use REGION=eu or REGION=ap in the line above or in your local .env file.

Region

If your subscription is in region other than US, you need to change the region in the configuration:

import (
    "github.com/fingerprintjs/fingerprint-pro-server-api-go-sdk/v7/sdk"
)

func main() {
    cfg := sdk.NewConfiguration()

    cfg.ChangeRegion(sdk.RegionEU) // or sdk.RegionAsia
}

Sealed results

This SDK provides utility methods for decoding sealed results. Install the sealed results dependency as below:

go get github.com/fingerprintjs/fingerprint-pro-server-api-go-sdk/v7/sdk/sealed

Then you can use below code to unseal results:

package main

import (
	"encoding/base64"
	"fmt"
	"github.com/fingerprintjs/fingerprint-pro-server-api-go-sdk/v7/sdk/sealed"
	"os"
)

// Utility function to decode base64 string
func base64Decode(input string) []byte {
	output, err := base64.StdEncoding.DecodeString(input)
	if err != nil {
		panic(err)
	}
	return output
}

func main() {
	// Sealed result from the frontend.
	sealedResult := base64Decode(os.Getenv("BASE64_SEALED_RESULT"))
	// Base64 encoded key generated in the dashboard.
	key := base64Decode(os.Getenv("BASE64_SEALED_RESULT_KEY"))

	keys := []sealed.DecryptionKey{
		// You can provide more than one key to support key rotation. The SDK will try to decrypt the result with each key.
		{
			Key:       key,
			Algorithm: sealed.AlgorithmAES256GCM,
		},
	}
	unsealedResponse, err := sealed.UnsealEventsResponse(sealedResult, keys)

	if err != nil {
		panic(err)
	}

	// Do something with unsealed response, e.g: send it back to the frontend.
	fmt.Println(unsealedResponse)
}

Webhook signing

This SDK provides utility method for verifing the HMAC signature of the incoming webhook request. Install the webhook dependency as below:

go get github.com/fingerprintjs/fingerprint-pro-server-api-go-sdk/v7/sdk/webhook

Then you can use below code to verify signature:

package main

import (
	"github.com/fingerprintjs/fingerprint-pro-server-api-go-sdk/v7/sdk/webhook"
)

func main() {
    // Your webhook signing secret.
    secret := "secret"

    // Request data. In real life scenario this will be the body of incoming request
    data := []byte("data")

    // Value of the "fpjs-event-signature" header.
    header := "v1=1b2c16b75bd2a870c114153ccda5bcfca63314bc722fa160d690de133ccbb9db"

    isValid := webhook.IsValidWebhookSignature(header, data, secret)

    if !isValid {
        panic("Invalid signature")
    }
}

To learn more, refer to example located in example/sealedResults.go.
