## Notes

- All requests use JSON:API specification
- Timestamps are in ISO 8601 RFC 3339 format
- Resource IDs are strings (often base64-encoded)
- Use sparse fieldsets to optimize response size (e.g., `fields[profile]=email,first_name`)
- Include `revision` header for API versioning
- Use cursor-based pagination with `page[cursor]` parameter
