Querying optin accounts to an application

hernandp · March 12, 2021, 2:37pm

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.

algorand-devrel/hackathon/blob/master/algorandsamples/v2/mypythondemo/pyteal/pyteal_dryrun_stateful_debugger.py

#!/usr/bin/env python3
import datetime
from pyteal import *

import base64
import os
from algosdk import account, algod, encoding, mnemonic, transaction
from algosdk.v2client import algod
from algosdk.future import transaction
from algosdk.future.transaction import StateSchema, ApplicationCreateTxn
from algosdk.v2client.models.dryrun_source import DryrunSource
from algosdk.v2client.models.dryrun_request import DryrunRequest
import json


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:

github.com

algorand/indexer/blob/develop/api/indexer.oas3.yml

{
  "components": {
    "parameters": {
      "account-id": {
        "description": "account string",
        "in": "path",
        "name": "account-id",
        "required": true,
        "schema": {
          "type": "string"
        }
      },
      "address": {
        "description": "Only include transactions with this address in one of the transaction fields.",
        "in": "query",
        "name": "address",

          "type": "string",
          "x-algorand-format": "Address"
        },

Here is an image of the response using postman. There is a run in postman button on this page btw…

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.
