Authorization: Bearer YOUR_API_KEYContext Headers
Most API endpoints require a context header to specify which entity (organization) you’re operating on:
x-entity-id— Used for most endpoints (invoices, customers, items, etc.). Specifies which entity’s data you’re accessing. Optional if your API key is scoped to a single entity.x-account-id— Used only for account-level operations like creating, listing, and managing entities. Optional if your user belongs to a single account.
Each endpoint’s documentation shows which header it requires.
