AEM Cloud Service - Get Adobe IMS JWT and AEM Access Token using POSTMan for SSO by Sreekanth Choudry Nalabotu

Abstract

Goal
This article is on using POSTMan requests to generate a long lived signed JWT token and exchange it with Adobe IMS for an IMS Access Token, valid for 24 hours. Using the access token you can make SSO requests to AEM sending the token in Authorization header. Check AEM documentation

var navigator = {};
var window = {};
var PRIVATE_KEY = "-----BEGIN RSA PRIVATE KEY-----\r\nMIIECvfNI=\r\n-----END RSA PRIVATE KEY-----\r\n"
var CLIENT_ID = "cm-pxxxx-exxxxx-integration";
var ORG_ID = "2Fxxxxxxx@AdobeOrg";
var SUBJECT = "31xxxxxx@techacct.adobe.com";
var META_SCOPE = "https://ims-na1.adobelogin.com/s/ent_aem_cloud_api";

pm.sendRequest('http://kjur.github.io/jsrsasign/jsrsasign-latest-all-min.js', (error, response) => {
if (error) {
console.log(error);
} else {
let resBody = new Buffer.from(response.stream).toString()

pm.globals.set("jsrsasign-js", resBody);

eval(pm.globals.get("jsrsasign-js"));

var jwt_payload = {
iss: ORG_ID,
sub: SUBJECT,
exp: Math.floor((Date.now() / 1000) + 3600 * 8),
aud: "https://ims-na1.adobelogin.com/c/" + CLIENT_ID,
META_SCOPE : true
}

var jwtToken = KJUR.jws.JWS.sign("RS256", '{"alg" : "RS256","typ" : "JWT"}', jwt_payload, PRIVATE_KEY);

postman.setEnvironmentVariable("jwt-token", jwtToken);
}
});

Thanks for sharing, I can get the access token via postman.

I have one question, Do you have any document to generate the access token by Java or something like that. I very much appreciate you.

Thank you
