The RudderStack Go SDK lets you track your customer event data from your Go applications and send it to your specified destinations via RudderStack.

Check out the GitHub codebase to get a more hands-on understanding of the SDK.

SDK setup requirements

To set up the RudderStack Go SDK, the following prerequisites must be met:

Go source write key
  • You will also need a data plane URL. Refer to the Glossary for more information on the data plane URL and where to find it.
The Setup tab in the RudderStack dashboard (seen above) has an SDK installation snippet containing both the write key and the data plane URL. You can use it to integrate the Go SDK into your application.

Installing the Go SDK

You can install the RudderStack Go SDK via the go get command. We highly recommend that you use a tool like Godep to avoid the issues related to any breaking API changes introduced between major versions of the library.

To install it in the GOPATH, run the following:

go get github.com/rudderlabs/analytics-go

Using the Go SDK

To use the SDK, run the following code snippet:

package main
import (
"github.com/rudderlabs/analytics-go"
)
func main() {
// Instantiates a client to use send messages to the Rudder API.
client := analytics.New(WRITE_KEY, DATA_PLANE_URL)
// Enqueues a track event that will be sent asynchronously.
client.Enqueue(analytics.Track{
UserId: "test-user",
Event: "test-snippet",
})
// Flushes any queued messages and closes the client.
client.Close()
}

Alternatively, you can run the following snippet:

package main
import (
"github.com/rudderlabs/analytics-go"
)
func main() {
// Instantiates a client to use send messages to the Rudder API.
client, _ := analytics.NewWithConfig(WRITE_KEY, DATA_PLANE_URL,
analytics.Config{
Interval: 30 * time.Second,
BatchSize: 100,
Verbose: true,
})
// Enqueues a track event that will be sent asynchronously.
client.Enqueue(analytics.Track{
UserId: "test-user",
Event: "test-snippet",
})
// Flushes any queued messages and closes the client.
client.Close()
}

The Config object parameters are described in the following table:

FieldTypePresenceDescription
Intervaltime.DurationOptionalMessages will be sent when this flushing interval time triggers
BatchSizeintOptionalTotal number of messages to be sent in a single batch
VerboseboolOptionalWhen set to true, the client will send more frequent and detailed messages to its logger
RetryAftertime.DurationOptionalThis can be used to set up how long the failed messages can be retried
maxConcurrentRequestsintOptionalThe maximum number of parallel goroutines which will be spawned
NoProxySupportboolOptionalSetting this variable to true will disable making calls to cluster-info end point

Users who do not use a proxy should set the NoProxySupport parameter to true while initializing the config.

// Instantiates a client to use send messages to the Rudder API.
client, _ := analytics.NewWithConfig(WRITE_KEY, DATA_PLANE_URL,
analytics.Config{
Interval: 30 * time.Second,
BatchSize: 100,
NoProxySupport: true,
})

Setting NoProxySupport to true will avoid RudderStack making calls to the proxy for fetching the total number of nodes, in case of multi-node setup.

Identify

The identify call lets you identify a visiting user and capture any related information such as their name, email address, etc.

RudderStack does not store the user state in any of the server-side SDKs. Unlike the client-side SDKs that deal with only a single user at a given time, the server-side SDKs deal with multiple users at the same time. Therefore, for any of the calls supported by the Node.js SDK, you need to specify either userId or anonymousId every time.

A sample identify call is as shown:

client.Enqueue(analytics.Identify{
UserId: "123",
Traits: analytics.NewTraits().
SetName("Name Surname").
SetEmail("name@example.com").
Set("plan", "Free").
Set("manager", 12),
})

The identify method parameters are as described below:

FieldTypePresenceDescription
anonymousIdStringOptionalSets the user ID for cases where there is no unique identifier for the user. Either userId or anonymousId is required.
userIdStringOptional, if anonymousId is already setUnique identifier for a particular user in your database.
contextObjectOptionalDictionary of information that provides context about a message. However, it is not directly related to the API call.
integrationsObjectOptionalA dictionary containing the destinations to be either enabled or disabled.
timestampDateOptionalThe timestamp of the message's arrival.
traitsObjectOptionalDictionary of the traits associated with the user, such as nameor email

Track

The track call lets you record the user actions along with their associated properties. Each user action is called an event.

A sample track call is shown below:

client.Enqueue(analytics.Track{
UserId: "123",
Event: "Signed Up",
Properties: analytics.NewProperties().
Set("plan", "Free"),
})

The track method parameters are as described below:

NameTypePresenceDescription
user_idStringRequiredThe developer identification for your user
eventStringRequiredName of the event being performed by the user
propertiesObjectOptionalDictionary of the properties associated with a particular event.
contextObjectOptionalDictionary of information that provides context about a message. However, it is not directly related to the API call.
timestampDateOptionalThe timestamp of the message's arrival.
anonymous_idStringOptionalSets the user ID for cases where there is no unique identifier for the user. Either userId or anonymousId is required.
integrationsObjectOptionalA dictionary containing the destinations to be either enabled or disabled.

Page

The page call allows you to record the page views on your website along with the other relevant information about the viewed page.

A sample page call is as shown:

client.Enqueue(analytics.Page{
UserId: "12345",
Name: "Pizza",
Properties: analytics.NewProperties().
SetURL("https://dominos.com"),
})

The page method parameters are as described below:

FieldTypePresenceDescription
anonymousIdStringOptionalSets the user ID for cases where there is no unique identifier for the user. Either userId or anonymousId is required.
userIdStringOptional, if anonymousId is already setUnique identifier for a particular user in your database.
contextObjectOptionalDictionary of information that provides context about a message. However, it is not directly related to the API call.
integrationsObjectOptionalA dictionary containing the destinations to be either enabled or disabled.
nameStringRequiredName of the page being viewed.
propertiesObjectOptionalDictionary of the properties associated with the page being viewed, such as url and referrer
timestampDateOptionalThe timestamp of the message's arrival.

Group

The group call lets you associate an identified user to a group - either a company, project or a team and record any custom traits or properties associated with that group.

A sample group call is as shown:

client.Enqueue(analytics.Group{
UserId: "12345",
GroupId: "1",
Traits: map[string]interface{}{
"name": "Company",
"description": "Facebook",
},
})

The group method parameters are as follows:

FieldTypePresenceDescription
anonymousIdStringOptionalSets the user ID for cases where there is no unique identifier for the user. Either userId or anonymousId is required.
userIdStringOptional, if anonymousId is already setUnique identifier for a particular user in your database.
contextObjectOptionalDictionary of information that provides context about a message. However, it is not directly related to the API call.
integrationsObjectOptionalA dictionary containing the destinations to be either enabled or disabled.
groupIdStringRequiredUnique identifier of the group, as present in your database.
traitsObjectOptionalDictionary of the properties or traits associated with the group, such as email or name.
timestampDateOptionalThe timestamp of the message's arrival.

Alias

The alias call lets you merge different identities of a known user.

alias is an advanced method that lets you change the tracked user's ID explicitly. This method is useful when managing identities for some of the downstream destinations.

A sample alias call is as shown:

client.Enqueue(analytics.Alias{
PreviousId: "12345",
UserId: "45678",
})

The alias method parameters are as mentioned below:

FieldTypePresenceDescription
userIdStringOptional, if anonymousId is already setUnique identifier for a particular user in your database.
contextObjectOptionalDictionary of information that provides context about a message. However, it is not directly related to the API call.
integrationsObjectOptionalA dictionary containing the destinations to be either enabled or disabled.
previousIdStringRequiredThe previous unique identifier of the user.
traitsObjectOptionalDictionary of the properties or traits associated with the group, such as email or name.
timestampDateOptionalThe timestamp of the message's arrival.

For a detailed explanation of the alias call, refer to the RudderStack API Specification guide.
