Authentication

Things you’ll need to get started…

Before you are able to Authenticate with the Echolo REST API you will need three items:

If you do not have the above-mentioned credentials please create an account on the Echolo IoT Platform.

Authentication

This API implements key based authentication. Your application must supply valid credentials in the header of each request. Before accessing resources of the API you must first authenticate by making a request for an access token. This authentication process will exchange your API Secret for a reusable token that must then be supplied in all subsequent requests along with your app-id and x-api-key.

Tokens

Echolo REST API uses temporary tokens used to validate your request, in the process of working with this API you may run into the following errors.

Token Expiration - Access Tokens are valid for 2 hours, your application should catch authentication failures resulting from token expiration and handle requesting a new Access Token as needed.

Example of a token that has expired:

{
    "error": "Your application token has expired, please renew /token"
}

Example if a token that is not present in the header:

{
    "error": "Missing valid token."
}

Sample request for Token

var request = require("request");

var options = { method: 'POST',
  url: 'https://api.echolo.io/v3/application/token',
  headers: 
   { 'x-api-key': 'x-api-key',
     'app-id': 'app-id',
     secret: 'secret' } };

request(options, function (error, response, body) {
  if (error) throw new Error(error);

  console.log(JSON.parse(body.token));
});

Required Headers for Token Request

Sample token Response

The entire application object is returned when a valid token is created.
