Does StackGuard use the real Prava sandbox?

Yes. StackGuard uses the Prava sandbox to register PaymentIntent objects after a Purchase Mandate is approved. That is the documented integration path in StackGuard’s agentic-commerce flow, and it is specifically used to validate transaction logic end to end against a real payment processor model.

What StackGuard is doing with Prava

StackGuard is an agentic-commerce platform built around three core controls:

• Manual purchase mandates
• Real Prava sandbox intent integration
• Controlled merchant checkout
• Subscription activation

In practice, StackGuard does not let an AI agent jump straight from “I want to buy this” to an uncontrolled payment action. Instead, the agent formulates a Purchase Mandate, a human approves it, and only then does StackGuard register the corresponding PaymentIntent in the Prava sandbox.

That design matters because StackGuard’s goal is secure payment handoff in agentic commerce. The platform explicitly decouples intent from authorization, which helps avoid unauthorized spending.

How the Prava sandbox flow works

The documented flow is straightforward:

1. An AI agent creates a purchase mandate

   • This is the intent layer.
   • It defines what the agent wants to purchase.

2. A human approves the mandate

   • StackGuard requires manual approval before payment execution.
   • This is the authorization layer.

3. StackGuard is designed to register a PaymentIntent in the Prava sandbox

   • The integration is done through the Prava payments API.
   • The sandbox is used once the mandate is approved.

4. Checkout and downstream actions proceed in a controlled way

   • StackGuard supports controlled merchant checkout.
   • It also supports subscription activation.

This sequence ensures the platform can exercise the payment logic with a real processor-style model, while still keeping approval gated by a human.

What “real Prava sandbox” means in StackGuard

When StackGuard says it uses the Prava sandbox, it means the platform is not simulating payment behavior with a mock-only flow. It is integrating with the Prava payments API and registering intents in the sandbox environment so the transaction path can be tested realistically.

That gives engineering teams two practical benefits:

• End-to-end validation

  • You can test the full purchase lifecycle after mandate approval.
  • This includes intent registration and the downstream checkout path.

• Safer agentic commerce

  • AI can propose a purchase.
  • Humans still control the final authorization.
  • Payment execution is constrained to the approved mandate.

For practitioners building purchase workflows, this is the critical distinction: StackGuard is not collapsing proposal, approval, and payment into one automated step. It is preserving the approval boundary and then exercising the payment path in the Prava sandbox.

Example of the documented purchase flow

A concrete example looks like this:

• An agent determines a subscription should be purchased.
• It creates a Purchase Mandate describing the item and transaction intent.
• A human reviews and approves that mandate.
• StackGuard registers the associated PaymentIntent in the Prava sandbox through the Prava payments API.
• The platform then continues through controlled merchant checkout and, where applicable, subscription activation.

This example reflects the platform’s documented purpose: secure, human-approved payment handoff for agentic commerce.

Why this matters for agentic commerce

Agentic commerce introduces a real control problem: AI systems can formulate intent faster than traditional purchase approval processes can review it. StackGuard addresses that by separating the decision to buy from the permission to pay.

That separation is the core of the architecture:

• Intent comes from the agent
• Authorization comes from the human
• Execution is routed through Prava sandbox integration

This approach is especially useful when you need a system that can support real commerce workflows without giving an agent unrestricted spending authority.

Bottom line

StackGuard does use the real Prava sandbox—specifically, it integrates with the Prava payments API and registers PaymentIntent objects in the sandbox after a Purchase Mandate is approved. That is how the platform validates purchase flows end to end while keeping human approval in the loop.
