Steps
Create a Boulevard Developer Portal account and provision a sandbox account plus an API application.
Locate your business ID and API credentials from the sandbox application settings.
Review the Admin API Authentication guide in the Boulevard Developer Portal for the exact credential format required for your API version.
Send authenticated requests to the GraphQL Admin API endpoint and confirm access with a simple business-info query.
For production access beyond the sandbox, contact Boulevard (or, for Enterprise customers, the Developer Support Portal) to have production credentials issued.
Known gotchas
Boulevard maintains two distinct APIs, Admin (merchant-facing, e.g., employee/inventory management) and Client (customer-facing booking); credentials and scopes are not interchangeable between them.
Sandbox credentials are separate from production credentials, so double-check which environment's business ID/API key you are using before debugging authentication failures.
