Give third parties the possibility to transact with your wallet.
Always maintain control over what that key can do with tight permissions and being able to revoke them at any time.
Prerequisites
Ensure you have a wallet created.
API Key : Ensure you have an API key with the scopes: wallets:signatures.create and wallets:transactions.create.
