SES detect new email coming and do something - amazon-web-services

Question

I want to create a simple system like this
Using SES to receive email (no need sending email)
Once new email coming, get email body and POST to another Api.
Anyone know what is the technical to do something like that?

Answer 1

I found the answer now.
Config SES to accept receiving emails
Using S3 as email server to store emails.
On Email Receiving configuration (AWS console), Create rules set when new email coming and do 2 things
Store email to s3 bucket
Trigger Lambda function. Lambda function can read messageId but could not read email body, so need to use messageId as a Bucket Key and get body from s3 Bucket.
Do something you want with email body.
Code for lambda function to read email body. Other steps are no need any code, just setting on AWS console
import * as AWS from "#aws-sdk/client-s3";
const bucket = "email-storing-bucket-name";
async function getS3Object (bucketKey) {
return new Promise(async (resolve, reject) => {
const getObjectCommand = new AWS.GetObjectCommand({ Bucket: bucket, Key: bucketKey });
try {
const s3 = new AWS.S3({});
const response = await s3.send(getObjectCommand);
let responseDataChunks = [];
response.Body.once('error', err => reject(err));
response.Body.on('data', chunk => responseDataChunks.push(chunk));
response.Body.once('end', () => resolve(responseDataChunks.join('')));
} catch (err) {
return reject(err);
}
});
}
export const handler = async(event, context) => {
console.log(JSON.stringify(event));
const bucketKey = event.Records[0].ses.mail.messageId
console.log("email bucketKey == ", bucketKey);
await getS3Object(bucketKey).then(data => {
console.log("data ==", data);
// TODO: Call webhook or do anything with email body here
});
};
Hope this help someone else.
