Elastic Email Go API Library

Introduction

When you integrate Elastic Email with your application, you can interact with your Elastic Email account directly by our API. You can easily integrate your email flow, manage your contacts and templates, send emails, and track email statistics directly from your app.

This page will help you easily integrate with Elastic Email using the Go library. You can find our whole downloadable Go repository on GitHub. You can also use our comprehensive API documentation.

Elastic Email API v4 uses REST architecture, which allows you to perform various code actions, including directly through your app.

The maximum email size of your entire message or message + attachment cannot exceed 20MB.

The attachment format is the file’s content as a byte array or a Base64 string.

The maximum number of recipients has no limit for one campaign. It depends on the pricing plan.

The API has a limit of 20 concurrent connections and a hard timeout of 600 seconds per request.

On this page, you will find how to authenticate your application and what the requirements for the integration are. You will be also provided with a quick start guide on how to start using API, followed by code samples. 

Authentication

To provide valid authentication and start using our API, you will need an API key. To generate your API key, enter settings on your Elastic Email account and go to Settings -> Manage API Keys -> Create or you can also click on the link: 

Create API key

At this point, you can set custom permissions and optional access for your API key. 

Security tip: The restriction forces the API Key to work only with an IP or IP range that will be specified in this field.

Once you create your API key, keep it safe as it will be used for every API call you make in order to identify you and confirm your account’s credentials. You can create either up to 15 or an unlimited amount of API keys based on your pricing plan. 

Your API key should be sent inside the header with the parameter name ‘x-elasticemail-apikey’ and your API key as a value.
