Fidelity and Third-Party Apps: How Read-Only Access Works

By Sam Davila on 2026-07-10 - 2 min read

Fidelity supports third-party app connections primarily for reading your data, through a consent system it controls tightly. Unlike developer-focused brokers, Fidelity does not offer a broad public trading API, so the realistic expectation for connected apps is portfolio visibility rather than order placement.

Fidelity in one paragraph

Fidelity is one of the largest asset managers and retail brokers in the world, strong in retirement accounts, index funds (including zero-expense-ratio funds), and research. It suits long-term investors first, active traders second, which is exactly why so many people hold Fidelity plus a second, more trading-oriented account.

How Fidelity handles third-party access

  • Consent-based data sharing: Fidelity moved away from password-based screen scraping toward tokenized, consent-driven access (its Fidelity Access program and the Akoya data network it spun out exist precisely for this). You authorize an app on Fidelity's side, and it receives read access without your password.
  • Read-only by design: connected apps can see balances, positions, and transactions. Trading through third-party retail apps is not part of Fidelity's public offering.
  • Revocation: authorized apps are visible in your Fidelity security settings and can be disconnected there at any time.

Why read-only still matters

Most of the value of a multi-account view is informational: seeing total exposure, catching duplicate positions across accounts, and getting news analysis that knows what you hold everywhere. A read-only Fidelity connection delivers all of that; orders simply continue to happen in Fidelity's own apps.

In a multi-broker setup

The classic pairing is Fidelity for retirement and long-term holdings plus an active account elsewhere. Connecting Fidelity to Sentient Logic brings those long-term positions into your combined view, so concentration checks and portfolio-aware news account for the biggest part of your net worth, not just the trading slice. Feature availability varies by broker and can change over time.
