addepy 0.4.0

Unofficial Python SDK for the Addepar API

AddePy

Unofficial Python SDK for the Addepar API.

Installation

Create a venv for your Python project, and then install addepy with:

pip install addepy

Setup

Create a .env file in your project with your Addepar credentials:

ADDEPAR_FIRM_NAME=yourfirm
ADDEPAR_FIRM_ID=12345
ADDEPAR_API_KEY=your_base64_encoded_api_key

ADDEPAR_FIRM_NAME is your URL subdomain: https://{ADDEPAR_FIRM_NAME}.addepar.com

Basic Usage

from addepy import AddePy

addepy = AddePy()  # Reads from .env automatically, or pass in config variables yourself

# List entities - Tier 1 Method
entity_types = addepy.ownership.entities.list_entity_types()

# Execute a portfolio query (submit, poll, download) - Tier 2 Method
results = addepy.portfolio.jobs.execute_portfolio_query(query_dict)

# Run an import (submit, poll, download) - Tier 2 Method
results = addepy.admin.import_tool.execute_import(df, "TRANSACTIONS")

The Import Tool via API is in Beta (as of 12/10/2025), so you may need to request access for your firm. However, this is a great tool... the Import Tool allows data management of almost all resources in Addepar...

Namespaces & Resources

The SDK mirrors the Addepar API documentation structure with three namespaces:

addepy.portfolio    → Market data & holdings
addepy.ownership    → Entity management
addepy.admin        → System & user management

Each namespace contains resources that map to API endpoints:

addepy.portfolio.jobs           # /v1/jobs
addepy.ownership.entities       # /v1/entities
addepy.admin.import_tool        # /v1/imports

Tier 1 vs Tier 2 Methods

Tier 1 - CRUD Operations

Direct wrappers around individual API endpoints.

Pattern	Purpose
create_*	Create a resource
get_*	Retrieve a resource
list_*	List resources (with pagination)
update_*	Update a resource
delete_*	Delete a resource

job_id = addepy.portfolio.jobs.create_job(query_dict)
status = addepy.portfolio.jobs.get_job_status(job_id)
results = addepy.portfolio.jobs.get_job_results(job_id)

Tier 2 - Orchestration

Combine multiple Tier 1 operations into a single call.

Pattern	Purpose
execute_*	Submit → Poll → Return results

# Does create_job + poll for completion + get_job_results
results = addepy.portfolio.jobs.execute_portfolio_query(query_dict)

Use Tier 1 when you need fine-grained control. Use Tier 2 for convenience.

Error Handling

from addepy import AddePyError, AuthenticationError, RateLimitError, ValidationError

try:
    results = addepy.ownership.entities.create_entity(...)
except ValidationError as e:
    print(f"Invalid input: {e}")
except RateLimitError as e:
    print(f"Rate limited. Retry after {e.retry_after} seconds")
except AddePyError as e:
    print(f"API error: {e}")

Logging

import logging

logging.getLogger("addepy").setLevel(logging.DEBUG)
logging.getLogger("addepy").addHandler(logging.StreamHandler())

Example Workflows

Real-world automation examples for wealth management firms:

Bulk Imports

import pandas as pd

# Prepare transaction data
attributes_df = pd.DataFrame({
    "Entity ID": [11111111, 22222222, 33333333],
    "Attribute Name": ["Portfolio Manager", "Trust Advisor", "Account Status"],
    "Attribute Value": ["Michael Scott", "Dwight Schrute", "Closed"],
})

# Execute import with polling
result = addepy.admin.import_tool.execute_import(
    data=attributes_df,
    import_type="ATTRIBUTES"
)

print(f"Imported {result['success_count']} transactions")

Audit & Compliance Monitoring

from addepy import AddePy
from datetime import datetime, timedelta

# 1. Query recent attribute changes on sensitive fields
week_ago = (datetime.now() - timedelta(days=7)).strftime("%Y-%m-%d")
changes = addepy.admin.audit.query_attribute_changes(
    start_date=week_ago,
    attribute_keys=["portfolio_manager"]
)

# 2. Flag changes for compliance review
flagged = flag_for_compliance(changes)  # Your custom logic

# 3. Generate report and notify stakeholders
send_compliance_report(flagged)  # Your email/Slack integration

Prospecting & Client Onboarding Workflows

# Create new client entity
client = addepy.ownership.entities.create_entity(
    entity_type_id="client",
    name="Smith Family Trust",
    attributes={"inception_date": "2024-01-15"}
)

# Create associated accounts
account = addepy.ownership.entities.create_entity(
    entity_type_id="account",
    name="Smith Brokerage Account",
    attributes={"account_number": "ABC-123456"}
)

# Link account to client via position
addepy.ownership.positions.create_position(
    owner_id=client["id"],
    owned_id=account["id"],
    inception_date="2024-01-15"
)

# Map to CRM system
addepy.ownership.external_ids.create_external_id_type(
    external_type_key="salesforce",
    display_name="Salesforce"
)

Rebalancing Analysis, Integrations w/ Trading Systems

# Get target allocations for a portfolio
allocations = addepy.admin.target_allocations.list_allocation_models()

# Compare current vs target
current_holdings = addepy.portfolio.analysis.query(
    columns=[{"key": "value"}, {"key": "weight"}],
    groupings=[{"key": "asset_class"}],
    portfolio_type="ENTITY",
    portfolio_id=12345,
    start_date="2024-12-01",
    end_date="2024-12-31"
)

# Calculate drift from targets
for holding in current_holdings["data"]["attributes"]["total"]["children"]:
    asset_class = holding["name"]
    current_weight = holding["columns"]["weight"]
    # Compare to target and flag if drift > threshold

Integration with External Systems (CRM, Custodians, Trading, etc.)

# Sync Salesforce contacts with Addepar entities
salesforce_contacts = get_salesforce_contacts()  # Your CRM API

for contact in salesforce_contacts:
    # Find matching Addepar entity by external ID
    entities = addepy.ownership.entities.list_entities(
        external_id_type="salesforce",
        external_id=contact["sf_id"]
    )

    if entities:
        # Update existing entity
        addepy.ownership.entities.update_entity(
            entity_id=entities[0]["id"],
            attributes={"email": contact["email"], "phone": contact["phone"]}
        )
    else:
        # Create new entity with external ID mapping
        addepy.ownership.entities.create_entity(
            entity_type_id="contact",
            name=contact["name"],
            external_ids=[{
                "external_type_key": "salesforce",
                "external_id": contact["sf_id"]
            }]
        )

Team Access Management

# Create a new team for junior analysts
team = addepy.admin.teams.create_team(
    name="Junior Analysts",
    description="Read-only access to client portfolios"
)

# Get the appropriate role
roles = addepy.admin.roles.list_roles()
analyst_role = next(r for r in roles if r["attributes"]["name"] == "Analyst")

# Add users to the team
users = addepy.admin.users.list_users()
junior_users = [u for u in users if "junior" in u["attributes"]["email"].lower()]

for user in junior_users:
    addepy.admin.teams.add_team_member(
        team_id=team["id"],
        user_id=user["id"],
        role_id=analyst_role["id"]
    )
