How do I get the transactionId from a raw transaction from v2 block explorer

Hi there, I’m having a really hard time trying to figure out how we get the transactionId/transactionHash for a given transaction when querying the block explorer like so

curl https://testnet-api.algonode.cloud/v2/blocks/37782706 | jq

it returns something like this.

  "block": {
    "gen": "testnet-v1.0",

How do I derive the transactionId from this for the given txn? is the only way to construct a Transaction class and use the .txID() method? Surely theres an easier way. (Not using an indexer)

Thanks

I use this to compute the txId from the algod data… vote-coin-indexer/src/algo/computeTransactionId.ts at 4bb4c9c83021bd29152a44b9168c9ca561093bd3 · scholtz/vote-coin-indexer · GitHub

@scholtz How are you using this function? Are you doing data conversion before putting the txn into the function?

when I attempt to pass the respective txn like in the example to that function I get
Error: address seems to be malformed
edit: Transaction.from_obj_for_encoding is expecting an EncodedTransaction I don’t think that passing the txn straight from the api works.

maybe this function is intended for usage with algod

this is where its being used: vote-coin-indexer/src/app.ts at 4bb4c9c83021bd29152a44b9168c9ca561093bd3 · scholtz/vote-coin-indexer · GitHub

yes, and you are using algod as well
