Custom API Integration Blueprint

Put a governance envelope around every custom outbound action.

Use Stacksona as a small pre-flight check between your agent runtime and the API, job, webhook, or database operation it wants to perform.

Governance object: outbound action envelope.

Where Stacksona sits

Agent intent

action envelope

Wrapper

Gate request

Reviewer

business decision

Decision

status + id

Downstream

run if approved

Audit

trace linked

The useful integration point is the last safe moment before an external action, privileged read, or customer-visible response occurs.

Implementation steps

Use these steps as the first implementation pass. Start with one high-risk action, verify the reviewer workflow, then expand coverage.

Normalize actionsRepresent each risky operation as an envelope with action, subject, risk, arguments, and correlation ids.
Call Gate before the operationThe wrapper asks for approval before invoking the downstream API, queue, database, or webhook.
Fail closed for risky workIf the decision is pending or rejected, return a safe blocked response to the agent and keep the action from running.
Log correlation idsStore the decision id with your job id, trace id, request id, and user id so audits can connect systems.

Recommended package

Use the Stacksona SDK or API wrapper

For Node.js or TypeScript guard services, start with the live SDK. For Python runtimes, call the same guard through your backend or a small HTTP wrapper.

npm i @stacksona/sdk

Approval payload to send

Keep the payload compact enough for a reviewer to decide quickly, but specific enough to explain exactly what the agent wants to do.

Field	What to include
agent	Stable name for the agent, crew, graph, or workflow that is asking for approval.
action	Human-readable verb such as `send_email`, `issue_refund`, or `execute_tool`.
risk	Use `low`, `medium`, or `high` so reviewers can triage quickly.
subject	The customer, ticket, repository, account, or data source affected by the action.
context	Small, reviewable facts: proposed arguments, policy signals, retrieved sources, role, task id, and links.

Generic HTTP/action wrapper

starter pattern

async function guardedAction({ action, subject, risk, args, run }) {
  const decision = await stacksona.gate.request({
    agent: 'custom-agent-runtime',
    action,
    risk,
    subject,
    context: {
      args,
      traceId: args.traceId,
      requestedBy: args.userId,
    },
  });

  if (decision.status !== 'approved') {
    return { blocked: true, decisionId: decision.id };
  }

  return run(args);
}

Treat this as the shape of the guard. Replace gate_request, stacksona.gate.request, or run_tool with the SDK/API calls used in your runtime.

Practical guidance

Best gate points

Outbound API clients, queue publishers, database writers, webhooks, and admin actions.

Reviewer context

Exact operation, arguments, requester, affected system, and rollback difficulty.

Avoid

Do not spread approval logic across every caller; centralize it in the wrapper.
