# ard-004: REST API for communication between UIs and the CRDT sync server

Satisfied by: task-015, task-016, task-017

## Problem

There needs to be an inter-process interface available at a distance between the
CRDT sync server and the UIs.

## Options

- Internet
  - Web
    - REST API
    - GraphQL API
  - Gopher
  - DNS
- Landline
- Carrier pigeon

## Decision

REST API. GraphQL is unfamiliar to me, and REST is adequate. All the other
options are silly.
