Two factor authentication required. User have to enter a code from SMS or TOTP code generator to pass 2fac. about facebook-java-business-sdk

This happens due to an enforcement on requiring 2fa on generating system user tokens. Right now the only workaround for developers is to generate the access token from the UI: https://business.facebook.com/settings/system-users or you could try to generate access tokens on non system users.

Hello @stcheng

Thank you for the response.

I can not use an access token of a non system user. I want to invite a user to an existing facebook business account:

        new Business.APIRequestCreateBusinessUser("181431399044864",FacebookUtil.createApiContext(request.getAccessToken()))
                .setEmail("[email protected]")
                .setRole(BusinessUser.EnumRole.VALUE_EMPLOYEE)
                .execute();

but it returns me:

{
"error": {
"message": "Application does not have permission for this action",
"type": "OAuthException",
"code": 10,
"error_data": {
"hash": null
},
"error_subcode": 2859030,
"is_transient": false,
"error_user_title": "This Action Is Not Allowed",
"error_user_msg": "Please retry this action in a few minutes",
"fbtrace_id": "AsErZRmD617WCt9yYFZkUZR"
}
}

My App and the access token I am using have the right permission to execute this action. My app has business_management permission (advanced access) and my user has an administrative role, which means I am able to invite the exact new user to the same business manager via facebook ui.

After some investigations I figured out that I can successfully execute the action if using an admin system user access token instead. Now I need to generate a system user access token programmatically.

@Denalda-lab right now we do not provide an official way to generate system user access tokens programmatically. thanks for understanding.

Thank you for the response @stcheng!

My last tentative: Is it any way to invite a user to join a business account by using an admin access token instead of an admin system user access token?

As I have mentioned above I try to make a call as below:

    new Business.APIRequestCreateBusinessUser("181431399044864",FacebookUtil.createApiContext(request.getAccessToken()))
            .setEmail("[email protected]")
            .setRole(BusinessUser.EnumRole.VALUE_EMPLOYEE)
            .execute();

My app has business_management permission (advanced access) and my user has an administrative role.

As a response I get:

{
"error": {
"message": "Application does not have permission for this action",
"type": "OAuthException",
"code": 10,
"error_data": {
"hash": null
},
"error_subcode": 2859030,
"is_transient": false,
"error_user_title": "This Action Is Not Allowed",
"error_user_msg": "Please retry this action in a few minutes",
"fbtrace_id": "AsErZRmD617WCt9yYFZkUZR"
}
}
