6. API Connectivity

Integration of Open API's in Rasa

To integrate any logical operations in rasa, we need to use Actions.py file

Here we are using open Api's https://apisetu.gov.in/directory/api/cowin/

• Create a new file main.py and paste below code, i was making a Get call here using Lattitude and Longitude values passed by the user in Bot.

import requests

def Dose_Availability_Lon_Lat(Lattitude,Longitude):
    api="https://cdn-api.co-vin.in/api/v2/appointment/centers/public/findByLatLong?lat={}&long={}".format(Lattitude,Longitude)
    return main_task(api)

def main_task(api):
    response=requests.get(api)
    data=response.json()['centers']
    output="*"*30
    # print(data)
    for area in data:
        output+="  Hospital Name:" + area['name'] + "*"*30 +"\n"
        output+='''\
pincode: {}
state_name: {}
district_name : {}
block_name : {}
'''.format(area['pincode'],area['state_name'],area['district_name',
area['block_name'])
            output+="*"*30
    return output

User input Values are stored using Slots.

with Domain.yml you can able to see Slots as Longitude and Lattitude

slots:
  lattitude:
    type: rasa.shared.core.slots.TextSlot
    initial_value: null
    auto_fill: true
    influence_conversation: true
  longitude:
    type: rasa.shared.core.slots.TextSlot
    initial_value: null
    auto_fill: true
    influence_conversation: true

and the connection between slots and the actions.py was done in stories.yml and rules.yml

  - rule: Activate location form
  steps:
  - intent: location
  - action: slot_location_form
  - active_loop: slot_location_form

- rule: Submit location form
  condition:
  # Condition that form is active.
  - active_loop: slot_location_form
  steps:
  # Form is deactivated
  - action: slot_location_form
  - active_loop: null
  - slot_was_set:
    - requested_slot: null
  # The actions we want to run when the form is submitted.
  - action: action_location_submit

after connecting all the things you need to train the Bot again

rasa train

to run actions.py you need to run actions command in seperate terminal

rasa run actions
