Many shopping carts have an entity limit in one request. Even if it is said that there is no limitation, you should be careful and not to include too many entities in a single API request since it may negatively affect your system and client’s store performance. It is better to extract data in smaller chunks (4­-50 items), what guarantees a correct result.

Notice that:

• BigCommerce limits the number of entities to 250 in a single API request.
• 3DCart has no official limits set but after the various requests test it is recommended not to exceed 100 entities.
• Shopify’s entity limit includes 250 in one request.
• Volusion has no limitation. However, we recommend not to include more than 50-100 entities.
