This page shows how to use the Gin framework with Sentry.

For a quick reference, there is a complete example at the Go SDK source code repository.

GoDoc-style API documentation is also available.


go get
import (

	sentrygin ""

// To initialize Sentry's handler, you need to initialize Sentry itself beforehand
if err := sentry.Init(sentry.ClientOptions{
	Dsn: "",
}); err != nil {
	fmt.Printf("Sentry initialization failed: %v\n", err)

// Then create your app
app := gin.Default()

// Once it's done, you can attach the handler as one of your middleware

// Set up routes
app.GET("/", func(ctx gin.Context) {
	ctx.String(http.StatusOK, "Hello world!")

// And run it


sentrygin accepts a struct of Options that allows you to configure how the handler will behave.

Currently it respects 3 options:

// Whether Sentry should repanic after recovery, in most cases it should be set to true,
// as gin.Default includes its own Recovery middleware that handles http responses.
Repanic bool
// Whether you want to block the request before moving forward with the response.
// Because Gin's default `Recovery` handler doesn't restart the application,
// it's safe to either skip this option or set it to `false`.
WaitForDelivery bool
// Timeout for the event delivery requests.
Timeout time.Duration


sentrygin attaches an instance of *sentry.Hub ( to the *gin.Context, which makes it available throughout the rest of the request's lifetime. You can access it by using the sentrygin.GetHubFromContext() method on the context itself in any of your proceeding middleware and routes. And it should be used instead of the global sentry.CaptureMessage, sentry.CaptureException, or any other calls, as it keeps the separation of data between the requests.

Keep in mind that *sentry.Hub won't be available in middleware attached before sentrygin!

app := gin.Default()

	Repanic: true,

app.Use(func(ctx *gin.Context) {
	if hub := sentrygin.GetHubFromContext(ctx); hub != nil {
		hub.Scope().SetTag("someRandomTag", "maybeYouNeedIt")

app.GET("/", func(ctx *gin.Context) {
	if hub := sentrygin.GetHubFromContext(ctx); hub != nil {
		hub.WithScope(func(scope *sentry.Scope) {
			scope.SetExtra("unwantedQuery", "someQueryDataMaybe")
			hub.CaptureMessage("User provided unwanted query string, but we recovered just fine")

app.GET("/foo", func(ctx *gin.Context) {
	// sentrygin handler will catch it just fine. Also, because we attached "someRandomTag"
	// in the middleware before, it will be sent through as well
	panic("y tho")


Accessing Request in BeforeSend callback

	Dsn: "",
	BeforeSend: func(event *sentry.Event, hint *sentry.EventHint) *sentry.Event {
		if hint.Context != nil {
			if req, ok := hint.Context.Value(sentry.RequestContextKey).(*http.Request); ok {
				// You have access to the original Request here

		return event
