Introduction

Welcome to the 20Echo API!

We have examples for curl and language bindings in Ruby and Elixir. You can view code examples in the dark area to the right, and you can switch the programming language of the examples with the tabs in the top right.

Authentication

To authorize, use this code:

# With shell, you can just pass the correct header with each request
curl -H "Authorization: your api key" "api_endpoint_here"
require '20e'

api = TwentyEcho::APIClient.new('your api key')
api = TwentyEcho.new(key: "your api key")

20echo uses API keys to allow access to the API. Contact support@20echo.com to discuss obtaining an API key.

20echo expects for the API key to be included in all API requests to the server in a header that looks like the following:

Authorization: your api key

Echoes

Get All Echoes

curl -H "Authorization: your api key" https://api.20echo.com/v1/echoes
require '20e'

api = TwentyEcho::APIClient.new('your api key')
api.echoes.get
api = TwentyEcho.new(key: "your api key")

TwentyEcho.Echo.get(api)

The above command returns JSON structured like this:
