What is b2c-scapi-shopper?

Guidance for calling Salesforce B2C Commerce Shopper APIs from a headless storefront—a website whose front end is separate from the commerce system. It covers customer-facing tasks such as products, baskets, orders, customer data, and shopper context.

Use it with PWA Kit, Storefront Next, or another headless commerce app when searching products, managing baskets, placing orders, handling customers, or setting shopper context.

It provides patterns for connecting a custom storefront to standard commerce services without guessing how the API interactions should work.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Skill manipulates agent memory, state, or stored context. Memory corruption can alter personality, override safety rules, or cause unpredictable behavior.

Fix: Protect agent memory and state from modification by untrusted content. Use read-only memory for critical instructions and validate all state changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00118	$0.00772
Opus 5.5	$0.00047	$0.00309
Sonnet 5.5	$0.00024	$0.00154
Haiku 4.5	$0.00012	$0.00077

Security

Grade A, and why

b2c-scapi-shopper scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 21d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Shopper Commerce APIs

Build storefront product, basket, checkout, customer, and context flows with SCAPI. For backend management use the b2c-scapi-admin skill.

Tool choice

When B2C MCP is available:

Read skill://mcp/b2c-mcp-scapi/SKILL.md once through resources or skills_read before code-mode tools; pass skillRead: true.
scapi_search with authType: "shopper" discovers bundled contracts offline. Find method/path/operationId first, then selected inputs, response fields, and security. Mixed Admin/Shopper operations can appear in either filter.
Shopper execution is unsupported in scapi_execute; adding a SLAS client cannot enable it. Execute storefront flows through the application's Shopper SDK/client with the appropriate SLAS token flow. Prefer dedicated tools where available.
scapi_schemas_list retrieves live tenant contracts and custom attributes; scapi_custom_apis_get_status checks custom registration. Code mode does not execute custom APIs.
config_inspect reports configured values with masking. docs_search/docs_read answer platform semantics, authentication, and limits; avoid duplicate contract reads.

CLI alternatives: b2c scapi schemas list, b2c scapi schemas get <family> <name> <version>, and b2c setup inspect. These schema commands use live Schemas API access; MCP discovery is offline.

Integration essentials

Reuse configured shortCode, organizationId, and siteId; do not invent identifiers.
Shopper authentication uses SLAS guest/registered flows and client scopes; Account Manager credentials are not a substitute. Keep private-client secrets and token exchange on the backend.
Discover the contract for the selected API version. Examples are illustrative; verify version-specific behavior and limits in official docs.
Preserve basket/order state and handle errors explicitly. Page/filter responses and return only fields needed by the next operation.
For headless payment authorization, inspect the order-PI hooks in the b2c-hooks skill ("Headless Order Payment") and the order lifecycle in the b2c-ordering skill before choosing a placement flow.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
