Work with Invitations - Amazon Managed Blockchain (AMB)

Work with Invitations

If you are invited to join a Hyperledger Fabric network on Amazon Managed Blockchain (AMB), you can accept the invitation by creating a member using the invitation ID. You can also reject the invitation. After you reject an invitation, the invitation ID is no longer valid. A new invitation proposal must be approved, and a new invitation ID is required to create a member. If don't accept or reject an invitation before it expires, the invitation lapses. As with a rejected invitation, a new invitation ID is required.

You can see all pending, accepted, and rejected invitations for your AWS account in the AWS Management Console. Alternatively, you can use the AWS CLI or the AMB Access SDK ListInvitations action.

You can set up Amazon CloudWatch Events along with Amazon Simple Notification Service so that you receive an alert when there is an invitation for your account. For more information, see Automating AMB Access Proposal Notifications with CloudWatch Events.

  1. Open the AMB Access console at https://console.aws.amazon.com/managedblockchain/.

  2. Choose Invitations, and then do one of the following:
