Wait for transaction by hash

Description

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.

Authentication

Authentication is via an 'Authorization: Bearer YOUR_API_ACCESS_KEY' header (which you must add to the sample requests).
