# Connect Stamped to AI Agents: Automate Loyalty and Store Data


You want to connect Stamped to an AI agent so your system can autonomously adjust VIP tiers, redeem loyalty rewards, read customer data, and sync e-commerce orders based on real-time events. Here is exactly how to do it using Truto's `/tools` endpoint and SDK, bypassing the need to build and maintain a custom Stamped API integration from scratch.

Giving a Large Language Model (LLM) read and write access to your e-commerce loyalty platform is an engineering headache. You either [spend weeks building, hosting, and maintaining a custom connector](https://truto.one/build-vs-buy-the-true-cost-of-building-saas-integrations-in-house/) to handle specific Stamped object schemas, or you use a managed infrastructure layer that handles the boilerplate for you. If your team uses ChatGPT, check out our guide on [connecting Stamped to ChatGPT](https://truto.one/connect-stamped-to-chatgpt-sync-customers-orders-and-loyalty/), or if you are building on Anthropic's models, read our guide on [connecting Stamped to Claude](https://truto.one/connect-stamped-to-claude-manage-store-catalog-and-vip-rewards/). For developers building custom autonomous workflows, you need a programmatic way to fetch these tools and bind them to your agent framework.

This guide breaks down exactly how to fetch [AI-ready tools for Stamped](https://truto.one/auto-generated-mcp-tools-for-ai-agents-a-2026-architecture-guide/), bind them natively to an LLM using frameworks like LangChain, LangGraph, CrewAI, or the Vercel AI SDK, and execute complex e-commerce workflows. For a deeper look at the architecture behind this approach, refer to our research on [architecting AI agents and the SaaS integration bottleneck](https://truto.one/architecting-ai-agents-langgraph-langchain-and-the-saas-integration-bottleneck/).

## Why a Unified Tool Layer Matters for Agent Safety

Before writing a line of integration code, decide what layer your agent talks to. This choice determines how safe your production system will be when executing actions against live store data.

Direct API tools (one tool per raw Stamped endpoint) look convenient in a prototype, but they push provider quirks directly into the LLM's context window. The model has to remember exactly how Stamped expects points to be debited, that loyalty campaign IDs are strictly required, and that almost every endpoint requires a specific `shop_id` tied to the multi-tenant architecture. Every one of those quirks is a hallucination waiting to happen.

A [standardized tool layer](https://truto.one/auto-generated-mcp-tools-for-ai-agents-a-2026-architecture-guide/) collapses these complexities behind a consistent schema. Your agent sees `create_a_stamped_loyalty_activity` and `list_all_stamped_customers_lookup` with explicitly defined arguments. That gives you concrete safety wins:

1. **Smaller attack surface for hallucination.** The LLM only ever chooses from a strict list of defined function names. It never invents query parameter strings or guesses at Stamped's internal routing IDs.
2. **Deterministic input validation.** Every tool has a strict JSON schema. Invalid arguments are rejected before they hit the Stamped API, meaning a broken tool call fails fast in your agent loop instead of corrupting a customer's loyalty balance.
3. **Decoupled authentication.** The agent never sees OAuth tokens or API keys. It just passes an integrated account identifier, and the underlying infrastructure applies the correct headers.

## The Engineering Reality of the Stamped API

Giving an LLM access to external data sounds simple. You write a fetch request, wrap it in a tool decorator, and move on. In production against complex e-commerce systems, this approach collapses. 

The Stamped API introduces several specific integration challenges that break standard REST assumptions. If you hardcode these interactions into your agent, you will spend your sprints writing defensive integration code instead of improving your model's reasoning.

### The Multi-Tenant Shop ID Requirement

Stamped is designed to overlay on top of existing e-commerce platforms like Shopify, BigCommerce, and WooCommerce. Because merchants can operate multiple storefronts under a single corporate entity, the Stamped API heavily relies on a `shop_id` parameter to route data correctly. 

Standard LLMs struggle with mandatory routing variables that have no semantic meaning to the end user. If an agent tries to update a customer profile but forgets the `shop_id` or hallucinates a Shopify internal ID instead of the Stamped store ID, the request will 404 or fail authorization. Your tooling layer must explicitly define this requirement in the JSON schema so the LLM knows it is non-negotiable for every operation.

### The Append-Only Loyalty Ledger

When a human user wants to "give a customer 500 points," an LLM naturally assumes there is a `points` field on the customer object it can update via a `PUT` or `PATCH` request. 

Stamped does not work this way. Points are managed via an append-only ledger system to prevent race conditions and ensure auditability. You cannot overwrite a balance; you must create a specific loyalty activity that debits or credits points. This requires the agent to understand the difference between adjusting a tier, redeeming a reward, and manually triggering a points rule. If you expose raw endpoints, the LLM will inevitably try to force a `PATCH /customer` with a `points: 1000` payload, which Stamped will reject.

### Complex Nested Cart States

When managing orders, Stamped relies on deeply nested `cartStates` to understand line items, fulfillment status, and pricing totals. If an agent needs to refund an order or update a shipping status, it must submit a highly structured JSON payload that matches Stamped's internal cart schema. Standard LLMs often flatten these structures or omit required fields like `currency` or `discount` arrays, leading to validation errors. Tools must aggressively enforce these nested structures via JSON schema properties.

## High-Leverage AI Agent Tools for Stamped

To safely navigate the Stamped API, Truto provides pre-defined, LLM-ready proxy tools. These tools wrap the underlying Stamped methods, handling authentication and providing the strict JSON schemas required for accurate function calling. 

Here are the highest-leverage tools available for autonomous e-commerce workflows.

### Lookup Customer

Before taking action on a loyalty account, the agent must resolve a human-readable identifier (like an email address) into a Stamped `customerId`. The `list_all_stamped_customers_lookup` tool allows the agent to search across the connected shop to find the exact customer record, returning their current points balance, VIP tier, and identifying tags.

> "Find the loyalty account for sarah.connor@example.com in shop 88472 and tell me her current VIP status and points balance."

### Adjust Customer VIP Tier

Often, support agents need to upgrade a customer's VIP status to resolve a complaint or reward high-value offline behavior. The `update_a_stamped_loyalty_customer_by_id` tool allows the agent to target a specific customer and explicitly set their `tierName`. 

> "Customer 991823 just completed a massive wholesale order via our B2B portal. Upgrade their Stamped loyalty tier to 'Platinum' in shop 88472."

### Trigger Custom Loyalty Activity

The `create_a_stamped_loyalty_activity` tool is the engine for programmatic point adjustments. Instead of updating a balance directly, the agent fires a custom activity rule (identified by `campaignId`). This adds points to the ledger securely and ensures the activity is tracked in the customer's history.

> "Give 500 apology points to customer 991823 for the shipping delay. Trigger campaign ID 'delay_apology_2026' in shop 88472."

### Redeem Loyalty Reward

When building autonomous checkout bots or proactive customer service agents, you need to allow users to cash in their points. The `create_a_stamped_loyalty_redemption` tool allows the agent to select a reward rule and debit the corresponding points from the customer's ledger, returning the generated coupon code.

> "Customer 991823 wants to use their points for a $20 off coupon. Redeem reward ID 'reward_20_off' for them in shop 88472 and give me the discount code."

### Manage Order State

E-commerce platforms rely on Stamped to trigger review request emails based on fulfillment status. The `update_a_stamped_order_by_id` tool allows the agent to modify the order's cart state - updating line items or financial status - ensuring Stamped's post-purchase flows remain synchronized with actual fulfillment reality.

> "Order #10045 was just split into two shipments. Update the cart states for order ID 55421 in Stamped (shop 88472) to reflect the new fulfillment status."

### Manage Product Catalog

To collect reviews, Stamped must know what you sell. The `create_a_stamped_product` tool allows agents managing your inventory system to automatically sync new SKUs, variants, and product imagery into Stamped as soon as they are created.

> "We just launched the 'Summer Canvas Tote'. Create a new product in Stamped for shop 88472 with vendor 'InHouse', status 'active', and pass the image URL."

## Workflows in Action

Exposing tools to an LLM is only useful if the agent can chain them together to solve real business problems. Here is how an autonomous agent uses these Stamped tools in production.

### Scenario 1: Autonomous Customer Appeasement

Customer support teams spend hours manually issuing "apology points" for delayed shipments. You can deploy an agent to read shipping updates and automatically handle the appeasement process.

> "A logistics alert just fired: Tracking number 1Z999 for sarah.connor@example.com is delayed by 4 days. Find her loyalty account in shop 88472, issue her 1,000 apology points, and draft an email apologizing for the delay."

1. The agent calls `list_all_stamped_customers_lookup` passing the email to retrieve the Stamped `customerId`.
2. The agent calls `create_a_stamped_loyalty_activity` passing the `customerId` and the `campaignId` for the standard shipping delay points rule.
3. The agent receives the successful activity receipt and drafts the email to the customer noting their new balance.

### Scenario 2: Offline-to-Online VIP Syncing

Omnichannel retailers often struggle to sync offline wholesale purchases with online VIP tiers. An agent can monitor offline enterprise CRM events and upgrade Stamped records dynamically.

> "Acme Corp just signed a $50k wholesale contract offline. Find their buyer's Stamped account (buyer@acmecorp.com) in shop 88472, and upgrade them immediately to the 'Diamond' VIP tier so their online portal reflects the discount."

1. The agent calls `list_all_stamped_customers_lookup` using the buyer's email address.
2. The agent identifies the `customerId` and current tier.
3. The agent calls `update_a_stamped_loyalty_customer_by_id` passing the specific `tierName` ("Diamond") to force the upgrade.
4. The agent verifies the payload response to ensure the tier was successfully updated.

## Building Multi-Step Workflows

To build these multi-step workflows, your agent needs an execution loop that can fetch the Stamped tools, bind them to the LLM, and execute them reliably. 

Truto provides a generic `/tools` endpoint that outputs standard JSON Schema. Our SDKs (like `truto-langchainjs-toolset`) wrap this endpoint so you can inject tools directly into frameworks like LangChain with a single method call.

### Handling API Rate Limits

When chaining multiple API calls in an [agentic loop](https://truto.one/architecting-ai-agents-langgraph-langchain-and-the-saas-integration-bottleneck/), you will eventually hit API rate limits. It is critical to understand how Truto handles these. 

**Truto does not automatically retry, throttle, or apply backoff logic when an upstream API returns a rate limit error.** 

If Stamped issues an HTTP 429, Truto passes that 429 directly back to your agent. However, Truto normalizes the rate limit headers into an IETF-compliant standard (`ratelimit-limit`, `ratelimit-remaining`, `ratelimit-reset`). Your agent architecture must catch tool execution errors, inspect these headers, and apply the appropriate sleep and retry logic.

Here is how you initialize the tools, bind them to a LangChain model, and construct a robust execution loop that respects rate limits.

```typescript
import { ChatOpenAI } from "@langchain/openai";
import { HumanMessage } from "@langchain/core/messages";
import { TrutoToolManager } from "truto-langchainjs-toolset";

async function runStampedAgent(prompt: string, integratedAccountId: string) {
  // 1. Initialize the LLM
  const model = new ChatOpenAI({
    modelName: "gpt-4o",
    temperature: 0,
  });

  // 2. Fetch Stamped tools from Truto for this specific merchant account
  const toolManager = await TrutoToolManager.from_integrated_account({
    integrated_account_id: integratedAccountId,
  });

  // 3. Bind the Stamped tools to the LLM
  const modelWithTools = model.bindTools(toolManager.get_tools());

  let messages = [new HumanMessage(prompt)];
  
  // 4. Standard Agent Execution Loop with Rate Limit Handling
  while (true) {
    const response = await modelWithTools.invoke(messages);
    messages.push(response);

    if (!response.tool_calls || response.tool_calls.length === 0) {
      // Agent is finished reasoning
      break;
    }

    // Execute each requested tool call
    for (const toolCall of response.tool_calls) {
      let success = false;
      let attempts = 0;
      const maxAttempts = 3;

      while (!success && attempts < maxAttempts) {
        try {
          attempts++;
          console.log(`Executing tool: ${toolCall.name}`);
          
          // Execute the tool against the Truto proxy
          const toolResult = await toolManager.execute_tool(toolCall);
          
          messages.push({
            role: "tool",
            name: toolCall.name,
            content: JSON.stringify(toolResult),
            tool_call_id: toolCall.id
          });
          
          success = true;

        } catch (error: any) {
          // Handle 429 Rate Limits Passed Down from Truto
          if (error.status === 429) {
            // Read the standardized Truto rate limit headers
            const resetTimeMs = parseInt(error.headers['ratelimit-reset'] || '5000', 10);
            console.warn(`Rate limited by Stamped. Sleeping for ${resetTimeMs}ms...`);
            
            await new Promise(resolve => setTimeout(resolve, resetTimeMs));
          } else {
            // Pass standard API errors (like 400 Bad Request) back to the LLM
            messages.push({
              role: "tool",
              name: toolCall.name,
              content: `Error executing tool: ${error.message}`,
              tool_call_id: toolCall.id
            });
            break; // Break the retry loop on non-retriable errors
          }
        }
      }
    }
  }

  return messages[messages.length - 1].content;
}

// Usage:
runStampedAgent(
  "Find the customer test@example.com in shop 88472 and tell me their points balance.", 
  "stamped-account-id-123"
).then(console.log);
```

### The Execution Flow

When the agent runs, the orchestration between your framework, Truto, and the Stamped API looks like this:

    LLM-->>App: "I have successfully issued 500 points."
```

## Moving Beyond the Integration Layer

Building autonomous workflows for e-commerce requires highly structured, deterministic access to the underlying platform APIs. If you rely on hand-rolled integration code, your engineering team will spend their cycles fighting Stamped's shop IDs, immutable ledger mechanics, and cart state validation errors instead of fine-tuning your LLM prompts.

By leveraging Truto's `/tools` endpoint, you [decouple the complexity of the SaaS integration layer](https://truto.one/build-vs-buy-the-true-cost-of-building-saas-integrations-in-house/) from your agent's reasoning loop. Your agents get the exact schemas they need to execute reliably, and your engineers get out of the business of managing third-party authentication and API boilerplate.
