Querying optin accounts to an application

hernandpHernán Di PietroMar 12, 2021

Hello guys, just a question

it is possible from client code to get the accounts that opted-in to a particular appId?

Thanks.

Yes, it is possible. … here is same sample code that goes thru the Application Life cycle. I stopped it after opting in, (if you let it run all the way thru, It will delete the application). This opts in for the creator account and a user account in the example.

def write_drr(res, contents):
    dir_path = os.path.dirname(os.path.realpath(__file__))
    path = os.path.join(dir_path, res)
    data = encoding.msgpack_encode(contents)
    data = base64.b64decode(data)

Here is the REST API endpoint and I did see the info in the response you are looking for…
/v2/accounts?limit=10&application-id=14718513

What language are you using?

The latest REST API file for Indexer can be found here:

Thank you very much, i will explore the indexer API.
However I guess the indexer at BETANET is broken now?

https://api.betanet.algoexplorer.io/idx2/v2/applications?application-id=3248449

Responds with:

{"applications":[],"current-round":8914539}

Thanks!

Are you sure this is a valid application ID?
Can you show the transaction ID creating it?

BetaNet Indexer has been unable to process new blocks since the first of two recent consensus updates, I would recommend developers work in TestNet or their own local DevNet.
