Firebase Remote Config SDK for Python

A Python SDK for managing Firebase Remote Config, built as a typed abstraction over the Firebase REST API. This package provides a convenient way to get, validate, update and upload remote config templates.

Features

• Provides SDK for managing Remote Config for mobile clients that is missing from Google firebase-admin package
• Type-safe interface using Pydantic models
• Minimal DSL for building and manipulating condition expressions
• Enables parsing condition expressions into Pydantic models

Capabilities

• Fetch and update Remote Config templates
• Validate template updates before deployment
• List template versions and perform rollbacks
• Add, query, and update conditions and parameters
• Serialize and parse condition expressions to/from structured form

Installation

pip install firebase-remote-config

Requirements

• Python 3.9 or higher
• Firebase project with Remote Config enabled
• Google credentials with the necessary permissions (Firebase Admin / Firebase Remote Config Admin). Any Application Default Credentials work: a service account, workload identity, or local user credentials from gcloud auth application-default login.

Usage

Getting Started

First, initialize the client with your Firebase credentials:

from google.oauth2 import service_account
from firebase_remote_config import RemoteConfigClient

# Initialize the client
credentials = service_account.Credentials.from_service_account_file('path/to/service-account.json')
client = RemoteConfigClient(credentials, 'your-project-id')

# Get current Remote Config template
config = client.get_remote_config()

# Upload template to Firebase Remote Config
updated_config = client.update_remote_config(config)

Authentication goes through google-auth's AuthorizedSession, so any Application Default Credentials work — including local user credentials:

import google.auth
from firebase_remote_config import RemoteConfigClient

# Resolve Application Default Credentials (service account, workload identity,
# or `gcloud auth application-default login`)
credentials, project_id = google.auth.default()
client = RemoteConfigClient(credentials, project_id)

The Remote Config REST API rejects user credentials that carry no quota project with 403 SERVICE_DISABLED. The client handles this by defaulting the quota project to project_id for user credentials; pass quota_project_id to bill a different project:

client = RemoteConfigClient(credentials, project_id, quota_project_id='billing-project')

The constructor also accepts a timeout (seconds, applied to every request; default 30). Pass timeout=None to disable it:

client = RemoteConfigClient(credentials, project_id, timeout=10)

Use Cases

1. Creating and Updating Parameters

import firebase_remote_config as rc

# Add new parameter to the remote config template
new_param = rc.RemoteConfigParameter(
    defaultValue=rc.RemoteConfigParameterValue(value="default_value"),
    valueType=rc.ParameterValueType.STRING,
    description="A new parameter"
)
config.template.parameters["new_parameter"] = new_param

# find parameter in the template
param = config.get_parameter_by_key("new_parameter")
param.description = "My new parameter"

2. Working with Conditional Values

import firebase_remote_config as rc

# Create condition object
condition = rc.RemoteConfigCondition(
    name="ios_users",
    expression="device.os == 'ios'",
    tagColor=rc.TagColor.BLUE,
)

# Create condition in rconfig template
config.create_condition(condition)

# Use newly created condition in a conditional value
config.set_conditional_value(
    param_key="my_parameter",
    param_value=rc.RemoteConfigParameterValue(value="my_value"),
    param_value_type=rc.ParameterValueType.STRING,
    condition_name="ios_users",
)

3. Building Complex Conditions with ConditionBuilder

import firebase_remote_config as rc
from firebase_remote_config.conditions import ConditionBuilder

# Create a complex condition
builder = ConditionBuilder()
builder.CONDITION().APP_VERSION().GTE("1.2.0")
builder.CONDITION().APP_USER_PROPERTY("total_purchases_usd").GTE(5)
builder.CONDITION().DEVICE_COUNTRY().IN(["US", "CA"])
cond_expr = builder.build()

# Serialize condition as string
cond_expr_str = str(cond_expr)
# app.version.>=(['1.2.0']) && app.userProperty['total_purchases_usd'] >= 5 && device.country in ['US', 'CA']

# Create condition in remote config template
config.create_condition(rc.RemoteConfigCondition(
    name="active_premium_users",
    expression=cond_expr_str,
    tagColor=rc.TagColor.GREEN,
))

4. Parsing condition expression

from firebase_remote_config.conditions import ConditionParser

# Parse condition expression
parser = ConditionParser()
cond_expr = "dateTime >= dateTime('2025-01-01T09:00:00') && app.userProperty['my_property'].contains(['abc', 'def'])"
condition = parser.parse(cond_expr)

# Compare string representations of the condition to the original expression
print(str(condition) == cond_expr)
# True

5. Version Management

# List recent versions
response = client.list_versions(page_size=30)
versions = response.versions

# Rollback to a previous version
rolled_back_config = client.rollback(version_number="42")
