Client for the Sendgrid v3 Web API

This client library is used by the other SendGrid service packages to make requests to the Sendgrid v3 Web API. You can also use it independently to make custom requests to the SendGrid v3 Web API and other HTTP APIs.

To be notified when this package is updated, please subscribe to email notifications for releases and breaking changes.



Obtain an API Key

Grab your API Key from the SendGrid UI.

Setup Environment Variables

Do not hard code your SendGrid API Key into your code. Instead, use an environment variable or some other secure means of protecting your SendGrid API Key. Following is an example of using an environment variable.

Update the development environment with your SENDGRID_API_KEY, for example:

echo "export SENDGRID_API_KEY='YOUR_API_KEY'" > sendgrid.env
echo "sendgrid.env" >> .gitignore
source ./sendgrid.env

Install Package

The following recommended installation requires npm. If you are unfamiliar with npm, see the npm docs. Npm comes installed with Node.js since node version 0.8.x therefore you likely already have it.

npm install --save @naturalcycles/sendgrid-client

You may also use yarn to install.

yarn add @naturalcycles/sendgrid-client

General v3 Web API Usage Example

Please see USAGE.md for all endpoint examples for the SendGrid v3 Web API.

Add a Custom Default Header

sgClient.setDefaultHeader('User-Agent', 'Some user agent string');

Change Request Defaults

sgClient.setDefaultRequest('baseUrl', 'https://api.sendgrid.com/');

Overwrite Promise Implementation

You can overwrite the promise implementation you want the client to use. Defaults to the ES6 Promise:
