This is a function that can be used to validate an access token received from Azure Active Directory. It is particularly useful when you're using a MSAL library to authenticate users on the frontend and you want to verify Microsoft tokens in the API.
For more information about the required props to validate your token and the library itself, please refer to the API Documentation
``js`
yarn add validate-azure-ad-token
npm install validate-azure-ad-token
1. Verify if all required props are passed in.
2. Decode the token using the jsonwebtoken library.
3. Send a request to https://login.microsoftonline.com/{tenantId}/discovery/keys?appid={applicationId} to receive all public keys unique to your applicationId and tenantId. This action is cached after one successful attempt.aud
4. Verify all required access token claims: , tid,iss,scp, appid, exp.
5. If the comparison succeeds, the token is valid.
`js
const validate = require('validate-azure-ad-token').default;
try {
const decodedToken = await validate('YOUR_MICROSOFT_ACCESS_TOKEN', {
tenantId: 'YOUR_TENANT_ID',
audience: 'YOUR_AUDIENCE_ID',
applicationId: 'YOUR_APPLICATION_ID',
scopes: 'YOUR_SCOPES', // for example ["User.Read"]
});
// DO WHATEVER YOU WANT WITH YOUR DECODED TOKEN
} catch (error) {
// ALL ERRORS GONNA SHOW HERE AS A STRING VALUE
}
