Set up

To interact with Lattice using the Lattice SDK, set up your authorization tokens and environment endpoint as system variables, then install the SDK in a language of your choice. Lattice provides the following canonical REST SDKs:

If you want to use the Lattice SDK for gRPC, see Generate the Lattice SDK for gRPC.

Before you begin

• If you do not have access to Lattice Sandboxes, or an existing Lattice deployment configured by Anduril, request to join the Lattice SDK developer program.

• If you are using Lattice Sandboxes, complete the steps in Developing with Lattice Sandboxes to create an environment and generate your authorization tokens.

• If you are using another deployment of Lattice, verify access to Lattice using your environment endpoint. If you can’t access the environment, contact your Anduril representative for help.

Set system variables

$
export LATTICE_ENDPOINT=$YOUR_LATTICE_ENDPOINT

$
export ENVIRONMENT_TOKEN=$YOUR_ENVIRONMENT_TOKEN

$
export SANDBOXES_TOKEN=$YOUR_SANDBOXES_TOKEN

$
echo $LATTICE_ENDPOINT
>
<environment_id>.env.sandboxes.developer.anduril.com

Get the SDK for REST

Lattice provides REST SDK support in the following languages:

$
go version

1
go get github.com/anduril/lattice-sdk-go/v2

1
package main
2
3
import (
4
    "github.com/anduril/lattice-sdk-go/v2/client"
5
    "github.com/anduril/lattice-sdk-go/v2/option"
6
)
7
8
func main() {
9
    client := client.NewClient(
10
        option.WithToken("LATTICE_TOKEN"),
11
        option.WithBaseURL("LATTICE_URL"),
12
    )
13
14
    client.Entities.GetEntity(
15
        context.TODO(),
16
        "ENTITY_ID",
17
    )
18
}

Generate the SDK for gRPC

To generate your own gRPC artifacts, choose a language from the Lattice SDK Buf Schema Registry. For additional information of using the Buf Schema Registry, please refer to their guide

For example, to generate the gRPC client and required server stubs in Go, do the following:

$
go mod init lattice-sdk-go-example

$
go get buf.build/gen/go/anduril/lattice-sdk/grpc/go@v1.5.1-20250716223851-f58576d79c34.2

1
package main
2
3
import (
4
    "buf.build/gen/go/anduril/lattice-sdk/grpc/go/anduril/entitymanager/v1/entitymanagerv1grpc"
5
)
6
7
func main() {
8
    client := entitymanagerv1grpc.NewEntityManagerAPIClient(conn)
9
10
    response, err := client.GetEntity(ctx, &entitymanagerv1.GetEntityRequest{
11
        EntityId: "<ENTITY_ID>",
12
    })
13
}
