## API gotchas

* Klaviyo uses Public API Key and Private API Key to access different endpoints.
* Endpoints that begin with `/api` need to be authenticated with private API key in the header.
* Endpoints that begin with `/client` need to be authenticatd with public API key in the query.
* All API calls must have *revision* as a header to resolve API versions.
