Monitor Algorand transactions

Who can guide me I how to monitor transactions. I’m building a Wallet app, I want to send notification to wallet user devices when they received a transaction from other. I didn’t find any post about it.
Please help me.
Thank you so much.

Hi, you have two choices:

  1. period request… see the source code of AWallet payment gatewayExample
  1. create your own indexer with websocket feeds… eg this one feeds graphql and using subscription you can get the notifications right away on new block. See VoteCoin indexer

@thangbk Btw if your goal is to create new wallet, perhaps you might clone/cooperate on AWallet… the first open source community algorand PWA wallet, currently supports multisig, rekeying, payment gateway, making account online …
