# google-cloud-beyondcorp Python Package Guide

## What This Entry Covers

This entry is pinned to the package version used here `google-cloud-beyondcorp==3.0.0`.

## Canonical Docs For Real Work

Use the service-specific official docs that match the BeyondCorp surface you are calling:

- AppConnections: `https://cloud.google.com/python/docs/reference/beyondcorp-appconnections/latest`
- AppConnectors: `https://cloud.google.com/python/docs/reference/beyondcorp-appconnectors/latest`
- AppGateways: `https://cloud.google.com/python/docs/reference/beyondcorp-appgateways/latest`
- ClientConnectorServices: `https://cloud.google.com/python/docs/reference/beyondcorp-clientconnectorservices/latest`
- ClientGateways: `https://cloud.google.com/python/docs/reference/beyondcorp-clientgateways/latest`

If the project already depends on the old umbrella package, keep the dependency pinned and verify the exact imports in that codebase before changing anything.

## Version-Sensitive Note

An older package reference pointed at `google-cloud-beyondcorp==3.0.0`, but Google Cloud's current official Python docs no longer use a single `beyondcorp/latest` reference as the primary navigation surface. For new code, pick the specific BeyondCorp service first, then use that service's generated client library docs.

That means agents should not assume:

- one package contains every BeyondCorp client
- the umbrella docs URL is the canonical current reference
- examples from one BeyondCorp service page apply to the others unchanged

## Install

```bash
python -m pip install "google-cloud-beyondcorp==3.0.0"
```

For new code, install the service-specific client package that matches the API you actually need. Typical packages are:

```bash
python -m pip install google-cloud-beyondcorp-appconnections
python -m pip install google-cloud-beyondcorp-appconnectors
python -m pip install google-cloud-beyondcorp-appgateways
python -m pip install google-cloud-beyondcorp-clientconnectorservices
python -m pip install google-cloud-beyondcorp-clientgateways
```

## Authentication And Setup

These clients follow the normal Google Cloud Python authentication model:

1. Enable the relevant BeyondCorp API in the target Google Cloud project.
2. Use Application Default Credentials.
3. Run locally with user ADC or in production with a service account.
4. Grant IAM roles on the project and BeyondCorp resources before debugging client code.

For local development, the common pattern is:

```bash
gcloud auth application-default login
```

Then set the project and location you will target:

```bash
export GOOGLE_CLOUD_PROJECT="my-project"
export GOOGLE_CLOUD_LOCATION="us-central1"
```

## Choosing The Right Client

Pick the client by resource family, not by the old umbrella package name:

- Use AppConnections when working with application connection resources.
- Use AppConnectors when managing connector resources.
- Use AppGateways when managing application gateways.
- Use ClientConnectorServices for connector services exposed to clients.
- Use ClientGateways for client gateway resources.

If you are not sure which service you need, start from the resource names already present in the project or Terraform config. The resource collection usually tells you which client page to open.

## Quick Start

This example uses the AppConnections client because it is one of the current official BeyondCorp Python references.

```python
import os

from google.cloud import beyondcorp_appconnections_v1

project_id = os.environ["GOOGLE_CLOUD_PROJECT"]
location = os.environ.get("GOOGLE_CLOUD_LOCATION", "us-central1")

parent = f"projects/{project_id}/locations/{location}"

client = beyondcorp_appconnections_v1.AppConnectionsServiceClient()

for app_connection in client.list_app_connections(parent=parent):
    print(app_connection.name)
```

Use the same overall pattern for the other BeyondCorp services:

- import the matching generated module
- create the service client
- build the `projects/{project}/locations/{location}` parent path
- call the list/get/create/update/delete method for that service

## Core Usage Patterns

### Resource Names Are Fully Qualified

Most methods expect resource names like:

```text
projects/PROJECT_ID/locations/LOCATION_ID/RESOURCE_COLLECTION/RESOURCE_ID
```

Do not pass a bare ID when the method expects a fully qualified resource name.

### Many Mutating Calls Use Long-Running Operations

Create, update, and delete operations in Google Cloud generated clients often return long-running operations. Wait for completion instead of assuming the initial RPC means the resource is ready.

```python
operation = client.create_app_connection(request=request)
result = operation.result(timeout=300)
print(result.name)
```

### Regional Endpoints Matter

The official BeyondCorp service docs note that some clients may require a regional endpoint. If you get endpoint or location mismatch errors, construct the client with `client_options` and use the region-specific endpoint documented for that service.

```python
from google.api_core.client_options import ClientOptions
from google.cloud import beyondcorp_appconnections_v1

client = beyondcorp_appconnections_v1.AppConnectionsServiceClient(
    client_options=ClientOptions(api_endpoint="REGIONAL_ENDPOINT")
)
```

Check the service-specific docs page before hardcoding an endpoint string.

## Common Pitfalls

- The docs URL is not the best current reference. Start from the service-specific docs roots above.
- Package names, import names, and client class names are not identical. Verify the generated import on the exact official page you are using.
- ADC may exist locally but still fail because the account lacks the required BeyondCorp IAM permissions.
- Location is part of the resource path. `us-central1` resources and `global` resources are not interchangeable.
- Generated clients use request objects or keyword arguments with exact field names. Do not invent field names from REST examples or older blog posts.
- For create or update flows, wait on the operation result before reading the resource back or using it in dependent calls.

## Practical Workflow For Agents

1. Confirm whether the codebase is pinned to `google-cloud-beyondcorp==3.0.0` or already uses one of the split packages.
2. Identify the exact BeyondCorp resource type the code needs.
3. Open the matching official service reference, not the old umbrella landing page.
4. Copy the generated client import, parent/resource path helpers, and request field names from that page.
5. Use ADC and verify IAM before treating `PermissionDenied` or `NotFound` as code bugs.
