Multiple slots in custom action

I am doing payment chat bot for that i am calling lot of API with large number of parameter values so i have to save these parameter values in different slots.So can you please let me know how can i set multiple slots in custom action.

Also if there is any other best way to store these multiple parameters values in slots so that i can access them in different classes please let me know(like inheritance in python class)

Thanks in advance

can any one help me with this

Hi @surya1994. Happy to help. Can you give me an example of what slots you would like to set? That would help me to give you the best advise :slight_smile:

Regarding accessing the slots in different classes - you can access the slots values using the tracker. So if the slots is set, the values should be accessible in any class using the method tracker.get_slot('slot_name')

Thanks @Juste Below is a story in which i will set username and password through forms( user_login_form) here in this story when user_login_form action gets activated it should take username and password and set them in slots instead it is throwing below error and all the actions are also showing same error. I already completed story without forms it is working fine so can you please let me know why i am facing error with forms and with required solution
