VTEX API
VTEX is a Latin American enterprise e-commerce platform exposing REST APIs for catalog management, order orchestration, checkout, customer data, promotions, and fulfillment across multi-account and multi-workspace setups.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
appKey/appToken pairs are long-lived credentials with no built-in rotation mechanism; agents should store them in secrets managers and implement manual rotation procedures. Role-based scoping via License Manager is available but often misconfigured in practice.
⚡ Reliability
Best When
You are operating an enterprise or mid-market retailer in Latin America with complex catalog, multi-warehouse fulfillment, and omnichannel needs that benefit from VTEX's unified commerce model.
Avoid When
You need a lightweight single-storefront solution or are outside VTEX's primary Latin American market where support and SLAs may be less reliable.
Use Cases
- • Sync product catalog and inventory levels from ERP systems into VTEX Catalog API on a schedule
- • Poll VTEX OMS (Order Management System) for new orders and push them downstream to fulfillment or 3PL systems
- • Create and update customer records in VTEX Master Data v2 as part of CRM integration flows
- • Trigger promotional price changes across SKUs by calling the Pricing API in bulk update loops
- • Read checkout simulation results to validate cart pricing and shipping options before surfacing to customers
Not For
- • Businesses outside VTEX's supported markets who need a simpler SaaS cart solution
- • Small merchants who need a low-cost storefront without per-request API complexity
- • Real-time sub-100ms checkout latency requirements where VTEX's multi-service architecture adds overhead
Interface
Authentication
Authentication uses paired appKey and appToken headers (X-VTEX-API-AppKey / X-VTEX-API-AppToken). Keys are generated per account in the VTEX admin and can be scoped with License Manager roles. Legacy APIs also support cookie-based auth but this is not recommended for agent use.
Pricing
VTEX is a closed enterprise platform; access requires a signed contract. Developer sandbox accounts are available but require sales engagement.
Agent Metadata
Known Gotchas
- ⚠ Every API URL must include both the accountName and environment (e.g., {accountName}.vtexcommercestable.com.br) — missing either causes 404s that are hard to distinguish from resource-not-found errors
- ⚠ VTEX has Legacy APIs (v1 Catalog) and current APIs (Catalog API v2, Master Data v2) — they are not compatible and have different auth and pagination styles; always confirm which version is in use
- ⚠ Workspace concept: changes made in a non-master workspace are not live until promoted; agents writing catalog data must target the correct workspace or edits silently disappear from production
- ⚠ Master Data v2 document IDs are caller-supplied UUIDs but the API will silently truncate or reject non-conforming IDs without a clear error, causing data loss
- ⚠ Rate limit 429 responses do not include a Retry-After header in all API families, requiring agents to implement exponential backoff with conservative defaults rather than reading the header
