Overview

Constructs a service interface object. Each API operation is exposed as a function on service.

Service Description

Amazon Managed Blockchain is a fully managed service for creating and managing blockchain networks using open-source frameworks. Blockchain allows you to build applications where multiple parties can securely and transparently run transactions and share data without the need for a trusted, central authority.

Managed Blockchain supports the Hyperledger Fabric and Ethereum open-source frameworks. Because of fundamental differences between the frameworks, some API actions or data types may only apply in the context of one framework and not the other. For example, actions related to Hyperledger Fabric network members such as CreateMember and DeleteMember don't apply to Ethereum.

The description for each action indicates the framework or frameworks to which it applies. Data types and properties that apply only in the context of a particular framework are similarly indicated.

Sending a Request Using ManagedBlockchain

var managedblockchain = new AWS.ManagedBlockchain();
managedblockchain.createAccessor(params, function (err, data) {
  if (err) console.log(err, err.stack); // an error occurred
  else     console.log(data);           // successful response
});

Locking the API Version

In order to ensure that the ManagedBlockchain object uses this specific API, you can construct the object by passing the apiVersion option to the constructor:

var managedblockchain = new AWS.ManagedBlockchain({apiVersion: '2018-09-24'});

You can also set the API version globally in AWS.config.apiVersions using the managedblockchain service identifier:

AWS.config.apiVersions = {
  managedblockchain: '2018-09-24',
  // other service API versions
};

var managedblockchain = new AWS.ManagedBlockchain();

Options Hash (options):

  • params (map) —

    An optional map of parameters to bind to every request sent by this service object. For more information on bound parameters, see "Working with Services" in the Getting Started Guide.

  • endpoint (String|AWS.Endpoint) —

    The endpoint URI to send requests to. The default endpoint is built from the configured region. The endpoint should be a string like 'https://{service}.{region}.amazonaws.com' or an Endpoint object.

  • credentialProvider (AWS.CredentialProviderChain) —

    the provider chain used to resolve credentials if no static credentials property is set.

  • region (String) —

    the region to send service requests to. See AWS.ManagedBlockchain.region for more information.

  • sslEnabled (Boolean) —

    whether to enable SSL for requests.

  • paramValidation (Boolean|map) —

    whether input parameters should be validated against the operation description before sending the request. Defaults to true. Pass a map to enable any of the following specific validation features:

    • min [Boolean] — Validates that a value meets the min constraint. This is enabled by default when paramValidation is set to true.
    • max [Boolean] — Validates that a value meets the max constraint.
    • pattern [Boolean] — Validates that a string value matches a regular expression.

  • systemClockOffset (Number) —

    an offset value in milliseconds to apply to all signing times. Use this to compensate for clock skew when your system may be out of sync with the service time.

Method Details

createAccessor(params = {}, callback) ⇒ AWS.Request

Creates a new accessor for use with Amazon Managed Blockchain service that supports token based access. The accessor contains information required for token based access.

Service Reference:

Examples:

Calling the createAccessor operation

var params = {
  AccessorType: BILLING_TOKEN, /* required */
  ClientRequestToken: 'STRING_VALUE', /* required */
  NetworkType: ETHEREUM_GOERLI | ETHEREUM_MAINNET | ETHEREUM_MAINNET_AND_GOERLI | POLYGON_MAINNET | POLYGON_MUMBAI,

  else     console.log(data);           // successful response
});

Parameters:

  • params (Object) (defaults to: {}) —
    • ClientRequestToken — (String)

      This is a unique, case-sensitive identifier that you provide to ensure the idempotency of the operation. An idempotent operation completes no more than once. This identifier is required only if you make a service request directly using an HTTP client. It is generated automatically if you use an Amazon Web Services SDK or the Amazon Web Services CLI.

      If a token is not provided, the SDK will use a version 4 UUID.
    • AccessorType — (String)

      The type of accessor.

      Note: Currently, accessor type is restricted to BILLING_TOKEN.
      Possible values include:
      • "BILLING_TOKEN"
    • Tags — (map<String>)

      Tags to assign to the Accessor.

      Each tag consists of a key and an optional value. You can specify multiple key-value pairs in a single request with an overall maximum of 50 tags allowed per resource.

      For more information about tags, see Tagging Resources in the Amazon Managed Blockchain Ethereum Developer Guide, or Tagging Resources in the Amazon Managed Blockchain Hyperledger Fabric Developer Guide.

    • NetworkType — (String)

      The blockchain network that the Accessor token is created for.

      Note:
      • Use the actual networkType value for the blockchain network that you are creating the Accessor token for.

        • ETHEREUM_MAINNET_AND_GOERLI
        • ETHEREUM_GOERLI
        • POLYGON_MUMBAI
        However, your existing Accessor tokens with these networkType values will remain unchanged.
      Possible values include:
      • "ETHEREUM_GOERLI"
      • "ETHEREUM_MAINNET"
      • "ETHEREUM_MAINNET_AND_GOERLI"
      • "POLYGON_MAINNET"
      • "POLYGON_MUMBAI"

Callback (callback):

  • function(err, data) { ... }

    Called when a response from the service is returned. If a callback is not supplied, you must call AWS.Request.send() on the returned request object to initiate the request.

    Context (this):

      • NetworkType — (String)

        The blockchain network that the accessor token is created for.

        Possible values include:
        • "ETHEREUM_GOERLI"

        • "ETHEREUM_MAINNET_AND_GOERLI"
        • "POLYGON_MAINNET"

      • KmsKeyArn — (String)

        The Amazon Resource Name (ARN) of the customer managed key in Key Management Service (KMS) to use for encryption at rest in the member. This parameter is inherited by any nodes that this member creates. For more information, see Encryption at Rest in the Amazon Managed Blockchain Hyperledger Fabric Developer Guide.

        Use one of the following options to specify this parameter:

        • Undefined or empty string - By default, use an KMS key that is owned and managed by Amazon Web Services on your behalf.

        • A valid symmetric customer managed KMS key - Use the specified KMS key in your account that you create, own, and manage.

          Amazon Managed Blockchain doesn't support asymmetric keys. For more information, see Using symmetric and asymmetric keys in the Key Management Service Developer Guide.

          The following is an example of a KMS key ARN: arn:aws:kms:us-east-2:111122223333:key/1234abcd-12ab-34cd-56ef-1234567890ab

    • Tags — (map<String>)

      Tags to assign to the network.

      Each tag consists of a key and an optional value. You can specify multiple key-value pairs in a single request with an overall maximum of 50 tags allowed per resource.

      For more information about tags, see Tagging Resources in the Amazon Managed Blockchain Ethereum Developer Guide, or Tagging Resources in the Amazon Managed Blockchain Hyperledger Fabric Developer Guide.
