How many API calls do I need for PromoStandards inventory monitoring?

The number of API calls depends on three factors: the number of products you track, the number of suppliers you connect to, and how frequently you want updates. The formula is (24 / update frequency in hours) × number of suppliers × number of products. For example, monitoring 20 products from 10 suppliers every 4 hours requires 1,200 API calls per day.

How many API calls does it take to import a product via PromoStandards?

Importing a single product requires approximately 9 API calls: 1 for Product Data, 1 for FOB Points, 2 for Blank Pricing (net and list), 2 for Decorated Pricing (net and list), 1 for Customer Pricing, 1 for Media Content, and 1 for Inventory. So importing 100 products would require about 900 API calls.

What is LAST_UPDATE_SEARCH in PromoStandards Order Status?

LAST_UPDATE_SEARCH is an efficient query method that retrieves all orders updated since your last check with a single API call per supplier, regardless of how many orders you have. This is much more efficient than polling each order individually.

How often should I update PromoStandards pricing data?

We recommend updating pricing data once a week. Each pricing update requires 7 API calls per product: 1 Product Data call, 1 FOB Points call, 2 Blank Pricing calls (net and list), 2 Decorated Pricing calls (net and list), and 1 Customer Pricing call.

Understanding PromoStandards API Usage

Inventory Monitoring

Real-time inventory data is critical for promotional products distributors. PSRESTful connects to the PromoStandards Inventory Service to fetch live stock levels from your suppliers. The number of API calls depends on how many products you track, how many suppliers you connect to, and how often you need updates. Most distributors update inventory every 4 to 6 hours.

Order Status Tracking

Track purchase orders across all your suppliers using the PromoStandards Order Status Service. You can poll individual orders for status updates, or use the more efficient LAST_UPDATE_SEARCH method, which returns all recently updated orders in a single API call per supplier — ideal for distributors managing hundreds of orders.

Pricing Updates

Keep your product pricing accurate with the PromoStandards Product Pricing and Configuration (PPC) Service. Each product update requires calls for FOB points, blank pricing (net and list), decorated pricing (net and list), and customer-specific pricing. We recommend refreshing pricing data weekly to stay competitive without excessive API usage.

Product Imports

Importing a new product catalog uses the Product Data, PPC, Media Content, and Inventory PromoStandards services. Each product requires approximately 9 API calls to fully import all data including pricing tiers, product images, and current stock levels. This is a one-time cost per product.

PromoStandards Services Used

PSRESTful converts complex SOAP/XML PromoStandards calls into simple REST/JSON APIs. The calculator above covers the most common services used by promotional products distributors:
