There are several ways you can get started with the SendGrid API.
These instructions describe how to send your first email using cURL calls. This is one of many ways to send email with the SendGrid API - we also have PHP, Python, Node.js, Java, C#, Go, and Ruby libraries.
Before you can start using the API, you need to do the following:
Your API call must have the following components:
https://api.sendgrid.com/v3/POST or PUT, you must submit your payload in JSON.The total message size should not exceed 20MB. This includes the message itself, headers, and the combined size of any attachments.
SendGrid recommends setting your server host to https://api.sendgrid.com/v3/
and not directly pointing to SendGrid IP addresses. SendGrid IP addresses
occasionally change without notice and hardcoding IP addresses, especially
without a way to regularly check for updates, can cause integrations to break.
Basic Authentication is no longer accepted; you must use an API key.
To Send an email using the SendGrid API:
1curl --request POST \2--url https://api.sendgrid.com/v3/mail/send \3--header 'Authorization: Bearer <<YOUR_API_KEY>>' \4--header 'Content-Type: application/json' \5--data '{"personalizations":[{"to":[{"email":"john.doe@example.com","name":"John Doe"}],"subject":"Hello, World!"}],"content": [{"type": "text/plain", "value": "Heya!"}],"from":{"email":"sam.smith@example.com","name":"Sam Smith"},"reply_to":{"email":"sam.smith@example.com","name":"Sam Smith"}}'
If you have not yet set up Sender Authentication in your account, you may need to check your spam folder for the email you just sent.

All responses are returned in JSON format. We specify this by sending the Content-Type header. The Web API v3 provides a selection of response codes, content-type headers, and pagination options to help you interpret the responses to your API requests.
