zi-api-auth-client
A library that supports username-password and PKI authentication methods for enterprise-api
Decision gist · record as of 2026-08-14
Yes, if you are building against ZoomInfo enterprise-api and need a straightforward authentication client. The package has low install friction, permissive licensing, and no known vulnerabilities. However, maintenance is aging (last commit 2025-09-04 with no recent activity), so verify that it remains compatible with current ZoomInfo API endpoints before adopting in new projects.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Private key must be formatted as a properly indented multi-line string; extra leading spaces will cause deserialization errors.
- Low install friction with three standard dependencies (PyJWT, requests, cryptography).
- Maintenance status is aging—last commit was 2025-09-04 but the package has not seen active development; repository is not archived.

What it is and what it does
zi_api_auth_client is a lightweight authentication client for ZoomInfo's enterprise-api. It provides two authentication flows: username/password authentication that returns a JWT token directly, and PKI authentication using a private key and client ID. Both methods produce JWT tokens suitable for subsequent API calls.
The package wraps cryptographic operations (via cryptography and PyJWT) and HTTP requests to handle the authentication handshake. It is designed as a thin client library for developers integrating with ZoomInfo's enterprise services. The main gotcha documented in the description is proper formatting of private keys as multi-line strings to avoid deserialization errors.
Use it for
- Authenticate to ZoomInfo enterprise-api using stored username and password credentials
- Generate JWT tokens for PKI-based authentication flows in enterprise integrations
- Obtain bearer tokens for subsequent HTTP API calls to ZoomInfo services
- Automate authentication in server-side applications that need to call enterprise-api
