Task - Issue an Identity to a Participant

Issuing an identity to a participant

An identity can be issued to a participant using either the API or the command line. Once an identity has been issued, the identity can then be used by the participant to interact with the business network in the context of that participant.

Fabric Composer issues identities as Hyperledger Fabric enrollment certificates (ECerts). An enrollment secret is generated that should be given to the participant, who can use the enrollment secret to download their enrollment certificate.

Before you start

Before you follow these steps, you must have added a participant to a participant registry.

The procedure below shows an example using the following model of a participant from the Getting Started walkthrough.

namespace net.biz.digitalPropertyNetwork

participant Person identified by personId {
  o String personId
  o String firstName
  o String lastName

The example assumes that an instance, net.biz.digitalPropertyNetwork#mae@biznet.org, of that participant has been created and placed into a participant registry.


  1. Issue an identity to the participant

    • JavaScript API
    let businessNetworkConnection = /* TODO: get a business network connection */
    businessNetworkConnection.issueIdentity('net.biz.digitalPropertyNetwork.Person#mae@biznet.org', 'maeid1')
        .then((result) => {
            console.log(`userID = ${result.userID}`);
            console.log(`userSecret = ${result.userSecret}`);
  • Command line

    composer identity issue -n 'digitalproperty-network' -i admin -s Xurw3yU9zI0l -u maeid1 -a "net.biz.digitalPropertyNetwork.Person#mae@biznet.org"

    The enrollment secret will be printed to the console.

  1. As the participant, test the connection to the business network

    • JavaScript API
    let businessNetworkConnection = /* TODO: get a business network connection */
        .then((result) => {
            console.log(`participant = ${result.participant ? result.participant : '<no participant found>'}`);
  • Command line

    composer network ping -n 'digitalproperty-network' -i maeid1 -s RJJmlOpvNVRV

    The participant ID will be printed to the console, and should match the participant ID that was specified in the composer identity issue command.
