How to verify payments using Talleo daemon.

Payments can be verified using payment ID, wallet address and private view key of the wallet.

The steps to verify payments using the RPC JSON API are:

1. Get current block height using “/getinfo”.
2. Pass payment ID to “/get_transaction_hashes_by_payment_id” to get list of transaction hashes.
   • If supported by daemon, set startIndex to 0 or first block height to include, and set endIndex to current block height – 10, so it won’t return transactions with less than 10 confirmations, includeUnconfirmed should be set to false.
3. Iterate through transaction hashes with “/get_transaction_details_by_hashes”.
   • If your daemon doesn’t support filtering by includeUnconfirmed, check for transactions where inBlockchain is true.
   • Verify that unlockTime is positive number less than current block height and that blockIndex is less than current block height – unlockTime.
4. Check that the blocks containing the transactions are not orphaned using block hashes from step 3 and “/get_blocks_details_by_hashes”.
5. Using “/get_amounts_for_account” check that the transactions contain enough outputs to the wallet, you need transaction hash, wallet address and private view key.
