Wait for transaction by hash

GET
/transactions/wait_by_hash/{txn_hash}
curl 'https://api.mainnet.aptoslabs.com/v1/transactions/wait_by_hash/{txn_hash}'

Same as /transactions/by_hash, but will wait for a pending transaction to be committed. To be used as a long poll optimization by clients, to reduce latency caused by polling. The “long” poll is generally a second or less but dictated by the server; the client must deal with the result as if the request was a normal /transactions/by_hash request, e.g., by retrying if the transaction is pending.

This is represented in a string as a 64 character hex string, sometimes shortened by stripping leading 0s, and adding a 0x.

For example, address 0x0000000000000000000000000000000000000000000000000000000000000001 is represented as 0x1.
