Greene Comply + Slack

Pause above-threshold agent transactions and route one-click approve or deny decisions to the team channel where operators already work.

Why it matters

The problem this solves.

Autonomous spend needs a fast human checkpoint when policy cannot safely auto-approve or deny. Greene Comply sends held transactions to Slack with signed approve and deny actions, so teams can verify exceptional spend without leaving the workflow or losing the audit trail.
How it works

The integration flow.

  1. 01

    Agent requests spend

    Your agent calls Greene Comply before executing a payment, subscription, card charge, or API top-up.

  2. 02

    Policy returns held

    Greene evaluates the guardrails and pauses requests that require human verification instead of auto-approving or denying.

  3. 03

    Slack receives the request

    A configured Slack approvals channel gets the amount, merchant, agent context, expiration, and secure decision buttons.

  4. 04

    Human approves or denies

    The Slack buttons use the same one-shot approval token as email links, so the dashboard, transaction, and audit log stay in sync.

  5. 05

    Agent waits for the decision

    The agent proceeds only after Greene records an approved decision; denied requests stop before the payment rail executes.
