Billbee API
Documentation of the Billbee REST API to connect a Billbee account to external aplications. ## Endpoint The Billbee API endpoint base url is https://api.billbee.io/api/v1 ## Activation You have to enable the API in the settings of your Billbee account. In addition you need a Billbee API Key identifying the application you develop. To get an API key, send a mail to support@billbee.io and send us a short note about what you are building. ## Authorization & security Because you can access private data with the Billbee API, every request has to be sent over https and must * Contain a valid API Key identifying the application/developer. It has to be sent as the HTTP header X-Billbee-Api-Key * Contain a valid user login with billbee username and api password in form of a basic auth HTTP header ## Throttling Each endpoint has a throttle of max 2 requests per second per combination of API Key and Billbee user. When you exceed these 2 calls, the API will return a HTTP 429 status code
Plan the first integration safely
The access fields below come from the connected directory. Their likely implementation impact is explained without assuming provider-specific behavior.
Authentication
OAuth is reported. Confirm flows, scopes, consent, token lifetime, and refresh rules.
Transport
HTTPS is not confirmed. Do not send credentials or production data until secure transport is verified.
Browser access
CORS is unknown. Treat direct browser access as unconfirmed and test before choosing a client-only architecture.
First-request sequence
- Identify the current base URL, version, and endpoint for the use case.
- Confirm how credentials are issued and where they may be stored.
- Test success, invalid input, throttling, unavailable data, and timeouts.
- Record response fields, pagination, caching, and error shapes.
- Add monitoring, retries with backoff, and an appropriate fallback.
Questions to resolve before production
Pricing and quotas
Confirm current plans, free-tier limits, overages, and request ceilings.
Endpoint coverage
Check that the operations and response fields match the intended workload.
Reliability
Look for uptime history, a status page, support routes, and service commitments.
Data and privacy
Review retention, licensing, regional processing, and compliance requirements.
Versioning
Confirm the active version, change policy, deprecation window, and migration guidance.
Developer experience
Validate SDKs, examples, error formats, pagination, and test environments.
