Deltek Ajera Python API Client

Deltek Ajera Python client

A typed Python client and command-line interface for the Deltek Ajera API.

Ajera exposes a single JSON-RPC style endpoint; this package wraps it in an ergonomic, fully type-hinted client built on Pydantic models, plus an ajera CLI for quick access from the terminal. Responses are validated and normalized into predictable Python objects so you can work with employees, projects, vendors, invoices, and general-ledger data without hand-rolling request payloads.

Features

• Typed models - every response is parsed into Pydantic models with descriptive fields.
• Python client and CLI - use it as a library or straight from the shell via ajera.
• Sensible defaults - handles session tokens and per-method API versions for you.
• Read and write - list, get, update, and create across the supported APIs.

Installation

pip install ajera
# or, with uv:
uv add ajera

Requires Python 3.12+.

Configuration

Credentials are read from environment variables (or can be passed directly to AjeraClient):

Variable	Description
AJERA_API_URL	The Ajera API endpoint URL for your tenant.
AJERA_API_USERNAME	API username.
AJERA_API_PASSWORD	API password.

export AJERA_API_URL="https://ajera.com/V0000000/AjeraAPI.ashx?..."
export AJERA_API_USERNAME="your-username"
export AJERA_API_PASSWORD="your-password"

For setting up an API user and generating credentials, see the Deltek Ajera Learning Hub API docs.

Quick start

Python

from ajera import AjeraClient

# Reads AJERA_API_URL / AJERA_API_USERNAME / AJERA_API_PASSWORD from the
# environment, or pass url=, username=, password= explicitly.
client = AjeraClient()

for employee in client.list_employees():
    print(employee.employee_key, employee.first_name, employee.last_name)

CLI

$ ajera employees list
[
  {
    "employee_key": 42,
    "first_name": "Ada",
    "last_name": "Lovelace",
    ...
  },
  ...
]

Note: List commands backed by an active/inactive status return only active records by default. Pass --status to override - e.g. --status Inactive, or --status Active --status Inactive to include both.
