#Use OpenID Connect to authenticate users

This feature is available on all SaaS environments and only since v6 for other types of environments.

This is an optional feature in Apps, you can also use your own Authentication.

To authenticate the users coming from Akeneo PIM, you can use the OpenID Connect protocol.

What is OpenID Connect?
OpenID Connect is a simple identity layer on top of the OAuth 2.0 protocol.
See OpenID official website for more info.

Basically, you use the same process as for Authorization, but you request an additional scope and you will receive, alongside the Access Token, an ID Token containing the information of the current user.

#Authenticate during the first Authorization request

If a user is trying to connect your App for the first time, and you want to authenticate him, ask for OpenID scopes during the Authorization Request.
        scope=openid email profile read_products write_products&

You can consult the list of available authentication scopes.

#Authenticate after the first Authorization request

If a user is trying to access your App from their Akeneo PIM, and you want to authenticate him, start an Authorization Request, even if you already are connected to their Akeneo PIM.

During this new Authorization Request, you must request all the scopes your App needs, including the Authorization scopes, in addition to the OpenID scopes.

#Extracting user information from the ID Token

At the end of the OAuth 2.0 process, if your Access Token Request is accepted, you will receive a JSON response with both tokens:

      "access_token": "Y2YyYjM1ZjMyMmZlZmE5Yzg0OTNiYjRjZTJjNjk0ZTUxYTE0NWI5Zm",
      "token_type": "bearer",
      "scope": "openid email profile read_products write_products",
      "id_token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiJ9.eyJpc3MiOiJodHRwOi8vM.XcmmANmSC2RHqWOI"

#Decoding the ID Token

An ID Token is a JWT composed of 3 parts encoded independently in base64: header.payload.signature.

We recommend using one of the libraries listed here with support for RS256 to decode it and retrieve the values inside the payload.

It's not recommended to try to decode and verify the ID Token yourself.


Once you've decoded the payload, it will look like this:

      "iss": "",
      "jti": "c76d558d-d10a-4bac-b320-12c22e36b3db",
      "sub": "c6acd619-8a08-46c2-9a5e-41a175d9149d",
      "aud": "206f450e-09a1-44ed-a0b3-9dd80f980ace",
      "iat": 1643029678.467703,
      "exp": 1643033278.467703,
      "email": "",
      "firstname": "John",
      "lastname": "Doe"
Field Description
iss URL of the token issuer
jti Unique identifier for the token
sub Unique user id
aud Id of the OAuth 2.0 client
iat Timestamp of token creation
exp Timestamp of token expiration
email (optional) Email of the user
firstname (optional) Firstname of the user
lastname (optional) Lastname of the user

Additional information (email, firstname, lastname, ...) are only present if you requested the corresponding authentication scopes and those were approved by the user.

email, firstname and lastname are values that can be edited on Akeneo PIM and are not verified by Akeneo. The only value that will truly identify a user is their unique user id in the subject claim (sub).


The ID Token sent by Akeneo PIM contains a signature, and you must verify it to guarantee that the payload has not be tampered with.

To validate the signature, you must retrieve the public key available at the URL {PIM}/connect/apps/v1/openid/public-key.

Then, follow the instructions of the library you are using.

The pair of private/public keys are regenerated regularly for security reasons. You should always retrieve the latest public key when validating a signature.
