How to use the SendGrid V3 API
Welcome to SendGrid’s Web API v3! This API is RESTful, fully featured, easy to integrate with, and offers support in 7 different languages.
To authenticate, add an
Authorization header to your API request that contains an API Key.
SendGrid’s Web API v3 supports the use of API Keys. API Keys allow you to use another method of authentication separate from your account username and password. API Keys add an additional layer of security for your account and can be assigned specific permissions to limit which areas of your account they may be used to access. API Keys can be generated in your account. To use keys, you must set a plain text header named “Authorization” with the contents of the header being “Bearer XXX” where XXX is your API Secret Key.
GET https://api.sendgrid.com/v3/resource HTTP/1.1 Authorization: Bearer Your.API.Key-HERE
curl -X "GET" "https://api.sendgrid.com/v3/templates" -H "Authorization: Bearer Your.API.Key-HERE" -H "Content-Type: application/json"
