Introduction

The Python Dialogflow CX Scripting API (DFCX SCRAPI) is a high level API that extends the official Google Python Client for Dialogflow CX. SCRAPI makes using DFCX easier, more friendly, and more pythonic for bot builders, developers, and maintainers.

What Can I Do With DFCX SCRAPI?

With DFCX SCRAPI you can perform many bot building and maintenance actions at scale including, but not limited to:

• Create, Update, Delete, Get, and List for all CX resources types (i.e. Intents, Entity Types, Pages, Flows, etc.)
• Convert commonly accessed CX Resources to Pandas Dataframes
• Have fully automated conversations with a CX agent (powerful for regression testing!)
• Extract Validation information
• Extract Change History information
• Search across all Flows/Pages/Routes to find a specific parameter or utterance using Search Util functions
• Quickly move CX resources between agents using Copy Util functions!
• Build the fundamental protobuf objects that CX uses for each resource type using Builder methods
• ...and much, much more!

Built With

• Python 3.8+

Authentication

Authentication can vary depending on how and where you are interacting with SCRAPI.

Google Colab

If you're using SCRAPI with a Google Colab notebook, you can add the following to the top of your notebook for easy authentication:

project_id = '<YOUR_GCP_PROJECT_ID>'

# this will launch an interactive prompt that allows you to auth with GCP in a browser
!gcloud auth application-default login --no-launch-browser

# this will set your active project to the `project_id` above
!gcloud auth application-default set-quota-project $project_id

After running the above, Colab will pick up your credentials from the environment and pass them to SCRAPI directly. No need to use Service Account keys! You can then use SCRAPI simply like this:

from dfcx_scrapi.core.intents import Intents

agent_id = '<YOUR_AGENT_ID>'
i = Intents() # <-- Creds will be automatically picked up from the environment
intents_map = i.get_intents_map(agent_id)

---

Cloud Functions / Cloud Run

If you're using SCRAPI with Cloud Functions or Cloud Run, SCRAPI can pick up on the default environment creds used by these services without any additional configuration!

1. Add dfcx-scrapi to your requirements.txt file
2. Ensure the Cloud Function / Cloud Run service account has the appropriate Dialogflow IAM Role

Once you are setup with the above, your function code can be used easily like this:

from dfcx_scrapi.core.intents import Intents

agent_id = '<YOUR_AGENT_ID>'
i = Intents() # <-- Creds will be automatically picked up from the environment
intents_map = i.get_intents_map(agent_id)

---

Local Python Environment

Similar to Cloud Functions / Cloud Run, SCRAPI can pick up on your local authentication creds if you are using the gcloud CLI.

1. Install gcloud CLI.
2. Run gcloud init.
3. Run gcloud auth login
4. Run gcloud auth list to ensure your principal account is active.

This will authenticate your principal GCP account with the gcloud CLI, and SCRAPI can pick up the creds from here.

---

Exceptions and Misc.

There are some classes in SCRAPI which still rely on Service Account Keys, notably the DataframeFunctions class due to how it authenticates with Google Sheets.

In order to use these functions, you will need a Service Account that has appropriate access to your GCP project.
For more information and to view the official documentation for service accounts go to Creating and Managing GCP Service Accounts.

Once you've obtained a Service Account Key with appropriate permissions, you can use it as follows:

from dfcx_scrapi.core.intents import Intents
from dfcx_scrapi.tools.dataframe_functions import DataframeFunctions

agent_id = '<YOUR_AGENT_ID>'
creds_path = '<PATH_TO_YOUR_SERVICE_ACCOUNT_JSON_FILE>'

i = Intents(creds_path=creds_path)
dffx = DataframeFunctions(creds_path=creds_path)

df = i.bulk_intent_to_df(agent_id)
dffx.dataframe_to_sheets('GOOGLE_SHEET_NAME', 'TAB_NAME', df)

Getting Started

Environment Setup

Set up Google Cloud Platform credentials and install dependencies.

gcloud auth login
gcloud auth application-default login
gcloud config set project <project name>

python3 -m venv venv
source ./venv/bin/activate
pip install -r requirements.txt

Usage

To run a simple bit of code you can do the following:

• Import a Class from dfcx_scrapi.core
• Assign your Service Account to a local variable

from dfcx_scrapi.core.intents import Intents

creds_path = '<PATH_TO_YOUR_SERVICE_ACCOUNT_JSON_FILE>'
agent_path = '<FULL_DFCX_AGENT_ID_PATH>'

# DFCX Agent ID paths are in this format:
# 'projects/<project_id>/locations/<location_id>/agents/<agent_id>'

# Instantiate your class object and pass in your credentials
i = Intents(creds_path, agent_id=agent_path)

# Retrieve all Intents and Training Phrases from an Agent and push to a Pandas DataFrame
df = i.bulk_intent_to_df()

Library Composition

Here is a brief overview of the SCRAPI library's structure and the motivation behind that structure.

Core

The Core folder is synonymous with the core Resource types in the DFCX Agents (agents, intents, flows, etc.)

• This folder contains the high level building blocks of SCRAPI
• These classes and methods can be used to build higher level methods or custom tools and applications

Tools

The Tools folder contains various customized toolkits that allow you to do more complex bot management tasks, such as

• Manipulate Agent Resource types into various DataFrame structures
• Copy Agent Resources between Agents and GCP Projects on a resource by resource level
• Move data to and from DFCX and other GCP Services like BigQuery, Sheets, etc.
• Create customized search queries inside of your agent resources

Builders

The Builders folder contains simple methods for constructing the underlying protos in Dialogflow CX

• Proto objects are the fundamental building blocks of Dialogflow CX
• Builder classes allow the user to construct Dialogflow CX resource offline without any API calls
• Once the resource components are constructed, they can then be pushed to a live Dialogflow CX agent via API
