Get Your Credentials

All users of the HERE platform must obtain authentication and authorization credentials.

For the available authentication options, see the Identity & Access Management Developer Guide.

Credential Options

The snippets below demonstrate different ways of supplying your platform credentials to the Data Client Base Library.

When you initialize a new service client without supplying any credentials as arguments, the Data Client Base Library attempts to find your platform credentials using the default credential provider chain: a platform credentials file in the JVM classpath, the default location platform credentials download location ($HOME/.here/credentials.properties) and the Java system properties in that order.

Set Your Credentials via the Application's Configuration File

This is the recommended approach.

Based on the values in the platform credentials, include the following parameters in your application.conf file:

com.here.platform.data.client.request-signer {
  billing-tag = "example_billing_tag"
  credentials {
    here-account {
      here-token-endpoint-url = "https://elb.cn-northwest-1.account.hereapi.cn/oauth2/token"
      here-client-id = "example-client-id"
      here-access-key-id = "example-access-key-id"
      here-access-key-secret = "example-access-key-secret"
    }
  }
}

com.here.platform.data.client.request-signer {
  billing-tag = "example_billing_tag"
  credentials {
    here-token = "example-token"
  }
}

Set Your Credentials in the Credentials File

The Data Client Base Library can read HERE access key and access secret data from the credentials.properties file.

• The client looks for a credentials.properties file in the Java Virtual Machine (JVM) classpath.

• A fallback location to find platform credentials is in $HOME/.here/credentials.properties

• Alternatively, you can specify an alternate credentials file location in the application.conf file.

  com.here.platform.data.client.request-signer {
    billing-tag = "example_billing_tag"
    credentials {
     file-path = "/path/credentials.properties"
    }
  }

Example of credentials properties file:

  here.user.id = example-here-user-id
  here.client.id=example-client-id
  here.access.key.id=example-access-key-id
  here.access.key.secret=example-access-key-secret
  here.token.endpoint.url=https://elb.cn-northwest-1.account.hereapi.cn/oauth2/token

Set Your Credentials via Java System Properties

To set your credentials via Java System Properties, define the following:

-Dcom.here.platform.data.client.request-signer.credentials.here-account.here-token-endpoint-url="https://elb.cn-northwest-1.account.hereapi.cn/oauth2/token"
-Dcom.here.platform.data.client.request-signer.credentials.here-account.here-client-id="example-client-id"
-Dcom.here.platform.data.client.request-signer.credentials.here-account.here-access-key-id="example-access-key-id"
-Dcom.here.platform.data.client.request-signer.credentials.here-account.here-access-key-secret="example-access-key-secret"

-Dcom.here.platform.data.client.request-signer.credentials.here-token="example-token"

Set Your Credentials Programmatically

To set your HERE account programmatically, include the following in your project:

val someCredentials = Some(
  HereAccountCredentials(
    "some-client-id",
    "some-access-key-id",
    "some-access-key-secret",
    "some-token-endpoint-url",
    Some("some-token-scope <optional>")
  ))
val client = BaseClient(ConfigFactory.load(), credentials = someCredentials)

HereAccountCredentials someCredentials =
    new HereAccountCredentials.Builder()
        .withHereClientId("some-client-id")
        .withHereAccessKeyId("some-access-key-id")
        .withHereAccessKeySecret("some-access-key-secret")
        .withHereTokenEndpointUrl("some-token-endpoint-url")
        .withHereTokenScope("some-token-scope <optional>")
        .build();
BaseClient client = new BaseClientJava.Builder().withCredentials(someCredentials).build();

To set your HERE token programmatically, include the following in your project:

val someCredentials = Some(HereTokenCredentials("some-access-token"))
val client = BaseClient(ConfigFactory.load(), credentials = someCredentials)

HereTokenCredentials someCredentials =
    new HereTokenCredentials.Builder().withHereToken("some-access-token").build();
BaseClient client = new BaseClientJava.Builder().withCredentials(someCredentials).build();
