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 
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
