​
API Flow

​
Standard Workflow (3 Steps)

The typical workflow for blockchain transactions:
  1. Prepare: Use POST /prepare-transactions to prepare unsigned transactions
  2. Sign: Sign the returned transactions using your preferred wallet/signing method
  3. Send: Submit signed transactions using POST /send-transactions
All transaction operations are centralized through the prepare-transactions endpoint, which supports multiple methods for different blockchain operations.

​
Simplified Workflow (1 Step) - Token Creation Only

For token creation without transaction management:
  • create-token-on-behalf: Use POST /create-token-on-behalf to create tokens automatically. Brickken handles signing and submission, eliminating manual transaction management.

​
Authentication

All API requests require authentication using an API key in the request headers: 
x-api-key: your-api-key-here
Include your unique API key in the x-api-key header of each request. Contact tech@brickken.com to obtain your API key.
