Aura Frames OpenAPI [unofficial]

This project attempts to map the Aura Frames REST API in use by the iPhone application

This API Currently supports simplistic data access. Accessing your frames, assets and the recursive objects below them.

Installation

Golang

go get github.com/bp1222/auraframes-api/auraframes

Language Documentation

Golang

Development

To build the API you need to install swagger-cli and openapi-generator

MacOS

npm install

Notice

The Aura Frames REST API does not allow for direct uploading of images. That seems to happen over a non-http protocol.

However, each frame has a email_address field which is an email you can send images to upload. Below is basic code to send an image (in the form of a URL) to the frame

import (
	"bytes"
	"encoding/base64"
	"fmt"

	"net/smtp"

	"path"
	"path/filepath"
	"strings"

	host       = os.Getenv("EMAIL_HOST")

	password   = os.Getenv("EMAIL_PASSWORD")
