Migrate from the Go HTTP Client to the Atlas Go SDK

Use this guide to migrate from the Go HTTP client ( go-client-mongodb-atlas ) to the Atlas Go SDK ( mongodb/atlas-sdk-go ).

The go-client-mongodb-atlas is deprecated and doesn't receive major feature updates. We strongly recommend migrating to the Atlas Go SDK for the latest changes. You can also migrate partially by using both libraries at the same time.

The Atlas Go SDK ( mongodb/atlas-sdk-go ) is based on the Atlas Admin API V2. The Atlas Go SDK simplifies the complexity of the versioned API by exposing the versioned API as Golang methods. Major SDK releases can introduce breaking changes only in a small subset of the Atlas Admin API endpoints.

The Atlas Go SDK doesn't rely on the deprecated go-client-mongodb-atlas. It changes how API requests are made, but minimizes the changes required for the end users.

The Atlas Go SDK has different methods for the initialization of the clients:

import admin "go.mongodb.org/atlas-sdk/v20231115014/admin"
sdk, err := admin.NewClient(
// Authentication using ApiKey and ApiSecret
admin.UseDigestAuth(apiKey, apiSecret))

Note: Both the deprecated go-client-mongodb-atlas and the Atlas Go SDK use Digest-based authentication. The same credentials apply.

To learn more, see Authenticate using the Atlas Go SDK.

Error handling requires developers to use dedicated methods for casting errors to API error objects:

apiErr, _ := admin.AsError(err)
log.Fatalf("Error when performing SDK request: %v", apiErr.GetDetail())

To learn more, see Error Handling.

The Atlas Go SDK changes the API interface to differentiate APIs from other methods.

Each API method has an API suffix. For example:

sdk.Projects will now sdk.ProjectsApi

Each method now explains the object that is created. For example:

sdk.Projects.create() will become sdk.ProjectsApi.createProject(...)

To learn more, see the Endpoint Documentation.

Model names and properties are formatted in PascalCase format for clarity and predictability of the methods and field names. For example, ClusterAWSProviderSettings will become now ClusterAwsProviderSettings.

The same applies to property names. For example, ID fields will become Id etc.

The Atlas Go SDK improves the clarity for request and response objects. For situations when the endpoint accepts multiple formats of the payload (polymorphism), you can specify instances of the API models that you want to use for a particular request. For example, when creating a cluster you can use one of the dedicated RegionConfigs objects (AWSRegionConfig, GCPRegionConfig, etc.):

//...
RegionConfig{
// Dedicated region config for AWS cloud
AWSRegionConfig: &mongodbatlas.AWSRegionConfig{
//AWS-specific fields are here
RegionName: &regionName,
},
}
//...
