How to use API Keys

The key mentioned in this documentation is your application's API key. You can create or view it in the User Center. Include it in the key header of every request. Keep it secret to prevent loss of funds.

Request method

The query interface uniformly uses the GET method request, and the operation interface uniformly uses the POST method request.

The content-type of the POST request header is:

application/json

Transaction inquiry

If an API response includes tx_id, frozen_tx_id, or a similar field, look up the transaction on TRONSCAN.
