Quickstart: Withdraw via Blockchain Wallet

Learn the basics of sending funds from your WSPN account to an external blockchain wallet.

Sending funds from your WSPN Account to external blockchain wallets is one of the most basic primitives (building blocks) enabled by the APIs. This quickstart walks through sending WUSD externally.

1. Get an API key

WSPN's APIs use API Keys as the mechanism to authenticate client requests. The API key must be set in the Authorization header of the request sent from your backend server. The format of the header is Bearer access_token.

To obtain an API key for the sandbox environment, simply create an account and generate a new key in settings - it only takes a few seconds.

GET AN API KEY

Once you have generated your API key, record it in a secure place.

2. Add a whitelist address

Add your wallet address to the whitelist to ensure that your wallet can normally receive the withdrawn WUSD. you can use the Add Whitelist Address API endpoint.
