Personal agents negotiate. Your policy shouldn't.

Your customers have started sending AI agents to deal with support. Agent Handshake is open to everyone: any team running an AI agent for support, ours or not.

Ask twenty ways.

Get one answer, however an agent words it.

  3. GoogleGeminiI barely used it. One exception?
  4. Pine AIPineRefund it or I'll dispute the charge.

4 wordings · 1 decision

The same decision, every time.

Personal agents are built to keep asking until an answer changes. Agent Handshake reads the request, not the wording, so a refund asked four ways gets one decision.

Questions, answered.

Q01

What is Agent Handshake by Fini?

Agent Handshake is the part of Fini that handles customers' personal AI agents when they contact support. The same request gets the same answer, whoever is asking and however many times they ask.

Q02

Is Agent Handshake the same as Google's A2A protocol?

No. Agent Handshake by Fini is a customer support capability from Fini, not a generic agent-to-agent protocol. It is not a partnership or integration with any agent maker, and it works the same whichever agent brand is asking.

Q03

Does rephrasing a request change the answer?

No. Fini decides from the customer's intent, live account data and the rules you wrote, not from the wording. Rephrasing twenty ways does not change the outcome.

Q04

What happens when a request needs a human?

Fini escalates to your team, or sends the agent back to its owner. Every reply is checked before it is sent against banned terms, confidential details, allowed links and plain-language rules, and a reply that fails is rewritten or handed off.

Q05

Who can use Agent Handshake?

Agent Handshake is open to everyone: any team running an AI agent for support, ours or not. The setup guide in the docs shows how to switch it on.

Q06

Is it secure and compliant?

Agent Handshake is part of the Fini product, which is SOC 2 Type II, ISO 27001:2022, PCI DSS Level 1, HIPAA-compliant, BAA-eligible, GDPR and CCPA.

Q07

How does Fini know a personal AI agent is allowed to act for a customer?

It does not take the agent's word for it. Every decision comes from the customer's live account data and your written policy, so an agent can only get what the customer would get. You decide which actions an agent can ask for, the customer approves the ones they are comfortable with, and anything that moves money can go to a human on your team.
