How to create participant and there identities via rest API in Hyperledger Composer

+1 vote

How do I create participant, their identities via rest API that generated by composer rest server without importing cards via import wallets? Couldn't find a proper documentation for this.

I searched for hours. This is the only page where I got the answer.
There's no single documentation telling how to create a participant.

I found this link, check it out. Not sure if it helps but here it is anyways:

Hi @Kumar, the link you shared is about adding the participant, there's nothing on creating the participant.

If you have already imported an Identity that can issue ither identities, then you can do the following:


- Browse for your exported admin card eg. netadmin.card and Import it.

- Add a participant, like in the below example:

Post /Trader

  "$class": "",
  "tradeId": "trader1",
  "firstName": "John",
  "lastName": "Doe"

- Issue an identity mapped to that participant above

POST /system/identities/issue:

You should get a business network card in your Downloads folder - from your REST server go to /Wallets

/POST /wallet/import

Import the wallet when prompted. Then set that as the default user if you want to use it in your browser.
