Is there a way to disconnect from Podio authentication?

i am currently working on a node.js app which waits for a item.create event in podio and then sends the item data + participation question via Slack to the user. I am using the password auth for testing purposes, which means that i am just storing the emails and pws to log into podio in a mongodb database. To send the data and participation question to the user i am using the mongoose stream function (much like a for loop, i think) to auth in podio with each user and then sending the information. I need to login/auth with each user seperatly in order to send the message to the right person in slack and set the participation for the specific user.

Problem: The sending to all users happens basically at the same time and podio always uses the authentication data was sent at last, as far is I see it. This means that i am just able to set the podio-event participation for the same user over and over again. Each user recieves a message with the participation question but it only effects the same account in podio over and over again. The "looping" happens in the cursor.on function.

I think the solution would be to disconnect every time podio has auth the user and i recieved the participation i need.

Any help would be highly appreciated. Thanks !
