Non-manual method for creating parties on DAML hub

Questions
1

Hi DAML community,

I’m trying to find a way to create many parties quickly on DAML hub (such as via API calls or a script) but it seems that it’s not currently supported.
May I know if there is an alternate solution to create a bunch of parties quickly without using the manual clicks required in DAML hub, both from the participant and admin view?

Thank you.

You can use the damlhub-cli utility: damlhub-cli - npm

See this part of the example script:

 for name in PartyA PartyB PartyC
 do
   damlhub -j ledger party ${LEDGER_ID} $name > /dev/null
 done
3

Thank you! Will try it out and report back.

Hi gyorg,

I attempted to run this command on an existing ledger on DAML hub :
damlhub -j ledger party <ledgerId> PartyA

after setting my jwt token copied from the identities tab in DAML hub.
I attempted to set the token as both

  • my damlhub account username’s part
  • the admin party manually created

But it returns the below error for both.

Unexpected error: FetchError: invalid json response body at 
https://login.hub.daml.com/auth/ledger/ujw59xsk3hjem7a8/user_grants reason: Unexpected token H in JSON at position 0
    at /usr/local/lib/node_modules/damlhub-cli/node_modules/node-fetch/lib/index.js:273:32
    at processTicksAndRejections (internal/process/task_queues.js:95:5) {
  type: 'invalid-json'
}

Am I wrongly allocating the JWT token?

Thanks,
Julius

Solved: Had to use the jwt token in the account settings for anyone else who may encounter this.
