The Go SDK provides a clean and idiomatic Go interface for integrating Dodo Payments into your applications. It offers context support, strongly typed responses, middleware capabilities, and is safe for concurrent use.

​
Installation

Install the SDK using Go modules: 
go get github.com/dodopayments/dodopayments-go
The SDK supports Go 1.18 and later versions, leveraging modern Go features for optimal performance.

​
Quick Start

Initialize the client and create your first checkout session: 
package main

import (
	"context"
	"fmt"
	"log"

	"github.com/dodopayments/dodopayments-go"
	"github.com/dodopayments/dodopayments-go/option"
)

func main() {
	client := dodopayments.NewClient(
		option.WithBearerToken("My Bearer Token"), // defaults to os.LookupEnv("DODO_PAYMENTS_API_KEY")
		option.WithEnvironmentTestMode(),          // defaults to option.WithEnvironmentLiveMode()
	)
	
	checkoutSessionResponse, err := client.CheckoutSessions.New(context.TODO(), dodopayments.CheckoutSessionNewParams{
		CheckoutSessionRequest: dodopayments.CheckoutSessionRequestParam{
			ProductCart: dodopayments.F([]dodopayments.CheckoutSessionRequestProductCartParam{{
				ProductID: dodopayments.F("product_id"),
				Quantity:  dodopayments.F(int64(1)),
			}}),
		},
	})
	if err != nil {
		log.Fatal(err)
	}
	fmt.Printf("Session ID: %s\n", checkoutSessionResponse.SessionID)
}
Always store your API keys securely using environment variables. Never hardcode them in your source code.

​
Configuration

​
Context and Timeouts

Leverage Go’s context for timeouts and cancellation: 
import (
	"context"
	"time"
	
	"github.com/dodopayments/dodopayments-go"
	"github.com/dodopayments/dodopayments-go/option"
)

// Create a context with timeout
ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second)
defer cancel()

payment, err := client.Payments.Create(ctx, dodopayments.PaymentCreateParams{
	Amount:     5000,
	Currency:   "USD",
	CustomerID: "cus_123",
})
if err != nil {
	if ctx.Err() == context.DeadlineExceeded {
		log.Println("Request timed out")
	} else {
		log.Fatal(err)
	}
}

​
Retry Configuration

Configure automatic retry behavior: 
// Configure default for all requests (default is 2)
client := dodopayments.NewClient(
	option.WithMaxRetries(0), // disable retries
)

// Override per-request
client.CheckoutSessions.New(
	context.TODO(),
	dodopayments.CheckoutSessionNewParams{
		CheckoutSessionRequest: dodopayments.CheckoutSessionRequestParam{
			ProductCart: dodopayments.F([]dodopayments.CheckoutSessionRequestProductCartParam{{
				ProductID: dodopayments.F("product_id"),
				Quantity:  dodopayments.F(int64(0)),
			}}),
		},
	},
	option.WithMaxRetries(5),
)

​
Common Operations

​
Create a Checkout Session

Generate a checkout session: 
session, err := client.CheckoutSessions.New(ctx, dodopayments.CheckoutSessionNewParams{
	CheckoutSessionRequest: dodopayments.CheckoutSessionRequestParam{
		ProductCart: dodopayments.F([]dodopayments.CheckoutSessionRequestProductCartParam{{
			ProductID: dodopayments.F("prod_123"),
			Quantity:  dodopayments.F(int64(1)),
		}}),
		ReturnURL: dodopayments.F("https://yourdomain.com/return"),
	},
})
if err != nil {
	log.Fatal(err)
}

fmt.Printf("Checkout URL: %s\n", session.URL)

​
Manage Customers

Create and retrieve customer information: 
// Create a customer
customer, err := client.Customers.New(ctx, dodopayments.CustomerNewParams{
	Email: dodopayments.F("customer@example.com"),
	Name:  dodopayments.F("John Doe"),
	Metadata: dodopayments.F(map[string]string{
		"user_id": "12345",
	}),
})
if err != nil {
	log.Fatal(err)
}

// Retrieve customer
customer, err = client.Customers.Get(ctx, "cus_123")
if err != nil {
	log.Fatal(err)
}

fmt.Printf("Customer: %s (%s)\n", customer.Name, customer.Email)

​
Handle Subscriptions

Create and manage recurring subscriptions: 
// Create a subscription
subscription, err := client.Subscriptions.New(ctx, dodopayments.SubscriptionNewParams{
	CustomerID: dodopayments.F("cus_123"),
	ProductID:  dodopayments.F("prod_456"),
	PriceID:    dodopayments.F("price_789"),
})
if err != nil {
	log.Fatal(err)
}

// Get usage history
usageHistory, err := client.Subscriptions.GetUsageHistory(
	ctx,
	subscription.ID,
	dodopayments.SubscriptionGetUsageHistoryParams{
		StartDate: dodopayments.F("2024-01-01T00:00:00Z"),
		EndDate:   dodopayments.F("2024-03-31T23:59:59Z"),
	},
)
if err != nil {
	log.Fatal(err)
}

​
Usage-Based Billing

​
Ingest Usage Events

Track custom events: 
import "github.com/dodopayments/dodopayments-go"

response, err := client.UsageEvents.Ingest(ctx, dodopayments.UsageEventIngestParams{
	Events: dodopayments.F([]dodopayments.UsageEventIngestParamsEvent{{
		EventID:    dodopayments.F("api_call_12345"),
		CustomerID: dodopayments.F("cus_abc123"),
		EventName:  dodopayments.F("api_request"),
		Timestamp:  dodopayments.F("2024-01-15T10:30:00Z"),
		Metadata: dodopayments.F(map[string]string{
			"endpoint":     "/api/v1/users",
			"method":       "GET",
			"tokens_used":  "150",
		}),
	}}),
})
if err != nil {
	log.Fatal(err)
}

​
List Usage Events

// List events with filters
params := dodopayments.UsageEventListParams{
	CustomerID: dodopayments.F("cus_abc123"),
	EventName:  dodopayments.F("api_request"),
}

events, err := client.UsageEvents.List(ctx, params)
if err != nil {
	log.Fatal(err)
}

for _, event := range events.Data {
	fmt.Printf("Event %s: %s at %s\n", event.EventID, event.EventName, event.Timestamp)
}

​
Error Handling

Handle specific error types: 
payment, err := client.Payments.Create(ctx, dodopayments.PaymentCreateParams{
	Amount:   5000,
	Currency: "USD",
})
if err != nil {
	if apiErr, ok := err.(*dodopayments.APIError); ok {
		fmt.Printf("API Error: %s\n", apiErr.Message)
		fmt.Printf("Status Code: %d\n", apiErr.StatusCode)
		fmt.Printf("Request ID: %s\n", apiErr.RequestID)
		
		// Handle specific error types
		switch apiErr.Type {
		case dodopayments.ErrorTypeAuthentication:
			log.Println("Authentication failed")
		case dodopayments.ErrorTypeInvalidRequest:
			log.Println("Invalid request parameters")
		case dodopayments.ErrorTypeRateLimit:
			log.Println("Rate limit exceeded")
		default:
			log.Printf("API error: %s\n", apiErr.Message)
		}
	} else {
		log.Fatal(err)
	}
}

​
Middleware

Add custom middleware for logging or metrics: 
func Logger(req *http.Request, next option.MiddlewareNext) (res *http.Response, err error) {
	// Before the request
	start := time.Now()
	log.Printf("Request: %s %s\n", req.Method, req.URL)

	// Forward the request to the next handler
	res, err = next(req)

	// After the request
	end := time.Now()
	log.Printf("Response: %d in %v\n", res.StatusCode, end.Sub(start))

	return res, err
}

client := dodopayments.NewClient(
	option.WithMiddleware(Logger),
)

​
Concurrency

The client is safe for concurrent use: 
package main

import (
	"context"
	"sync"
	"log"

	"github.com/dodopayments/dodopayments-go"
)

func main() {
	client := dodopayments.NewClient()
	
	var wg sync.WaitGroup
	for i := 0; i < 10; i++ {
		wg.Add(1)
		go func(idx int) {
			defer wg.Done()
			
			payment, err := client.Payments.Create(context.Background(), dodopayments.PaymentCreateParams{
				Amount:     1000,
				Currency:   "USD",
				CustomerID: "cus_123",
			})
			if err != nil {
				log.Printf("Failed to create payment %d: %v", idx, err)
				return
			}
			
			log.Printf("Created payment %d: %s", idx, payment.ID)
		}(i)
	}
	
	wg.Wait()
}
