convoy-go

This is the Golang SDK for Convoy. It makes it easy to interact with the Convoy API. You can view the full API Reference here

Installation

$ go get github.com/frain-dev/convoy-go/v2

Usage

To begin you need to define a Client.

Configure your Client

Below are the several ways you can configure a client depending on your needs.

// Convoy Cloud (US): https://us.getconvoy.cloud/api/v1
// Convoy Cloud (EU): https://eu.getconvoy.cloud/api/v1
// Self-hosted: https://your-instance/api/v1
baseURL := "https://us.getconvoy.cloud/api/v1"

// Regular Client
c := convoy.New(baseURL, apiKey, projectID)

// Add a Custom HTTP Client
client := &http.Client{}
c := convoy.New(baseURL, apiKey, projectID,
    convoy.OptionHTTPClient(client))

// Add a SQS Client 
so := &convoy.SQSOptions{
    Client: sqs.New(),
    QueueUrl: "queue-url",
}
c := convoy.New(baseURL, apiKey, projectID,
    convoy.OptionSQSOptions(so))

// Add a Kafka Client 
ko := &convoy.KafkaOptions{
    Client: &kafka.Client{},
    Topic: "kafka-topic",
}
c := convoy.New(baseURL, apiKey, projectID,
    convoy.OptionKafkaOptions(ko))

Please see go reference for other options available to use to configure your client.

Creating Endpoints

body := &convoy.CreateEndpointRequest{
    Name: "endpoint-name",
    // Get a test ingest URL from https://playground.getconvoy.io
    URL: "https://us.getconvoy.cloud/ingest/DQzxCcNKTB7SGqzm",
    Secret: "endpoint-secret",
    SupportEmail: "notifications@getconvoy.io",
}

endpoint, err := c.Endpoints.Create(ctx, body, nil)
if err != nil {
    return err
}

Store the Endpoint ID, so you can use it in subsequent requests for creating subscriptions or sending events.

Creating Subscriptions

body := &convoy.CreateSubscriptionRequest{
    Name: "endpoint-subscription",
    EndpointID: "endpoint-id",
    FilterConfig: &convoy.FilterConfiguration{
        EventTypes: []string{"*"},
    },
}

subscription, err := c.Subscriptions.Create(ctx, body)
if err != nil {
    return err 
}

Sending Events

You can send events to Convoy via HTTP or via any supported message broker. See here to see the list of supported brokers.

HTTP

// Send an event to a single endpoint.
body := &CreateEventRequest{
    EventType: "event.type",
    EndpointID: "endpoint-id",
    IdempotencyKey: "unique-event-id",
    Data: []byte(`{"version": "Convoy v24.0.0"}`),
}

event, err := c.Events.Create(ctx, body)
if err != nil {
    return err 
}

// Send event to multiple endpoints.
body := &CreateFanoutEventRequest{
    EventType: "event.type",
    OwnerID: "unique-user-id",
    IdempotencyKey: "unique-event-id",
    Data: []byte(`{"version": "Convoy v24.0.0"}`),
}

event, err := c.Events.FanoutEvent(ctx, body)
if err != nil {
    return err 
}

Note: The body struct used above is the same used for the message brokers below.

SQS

// Send event to a single endpoint.
err := c.SQS.WriteEvent(ctx, body)
if err != nil {
    return err 
}

// Send event to multiple endpoints.
err := c.SQS.WriteFanoutEvent(ctx, body)
if err != nil {
    return err 
}

Kafka

This library depends on kafka-go to configure Kafka Clients.

// Send event to a single endpoint.
err := c.Kafka.WriteEvent(ctx, body)
if err != nil {
    return err 
}


// Send event to multiple endpoints.
err := c.Kafka.WriteFanoutEvent(ctx, body) 
if err != nil {
    return err 
}

Verifying Webhooks

This client supports verifying simple and advanced webhook signatures. Verify with the raw request body, before parsing it.

webhook := convoy.NewWebhook(&convoy.WebhookOpts{
    Secret: "endpoint-secret",
})

// Verify an incoming *http.Request. This reads the request body; read it
// yourself first and use VerifyPayload if you need the body afterwards.
func handler(w http.ResponseWriter, r *http.Request) {
    body, err := io.ReadAll(r.Body)
    if err != nil {
        http.Error(w, "failed to read body", http.StatusBadRequest)
        return
    }

    if err := webhook.VerifyPayload(body, r.Header.Get("X-Convoy-Signature")); err != nil {
        http.Error(w, "invalid signature", http.StatusBadRequest)
        return
    }

    // signature is valid; process the event using body
    w.WriteHeader(http.StatusOK)
}
