Exact Online API Limits working with App4Sales

App4Sales ensures your data stays fully in sync with Exact Online while respecting API limits. Our integration keeps updates, stock levels, and orders accurate and up-to-date, so you can focus on business without worrying about technical restrictions. It works for both our B2B and B2C e-commerce products. 

Introduction: Working in Harmony with Exact Online’s API Rules

Exact Online’s API limits are part of their standard approach to ensuring the platform remains fast, stable, and secure for all users. These limits define how many times an external system can connect within a given timeframe.

For businesses that rely on integrations, this is simply part of the normal technical framework. The good news? App4Sales is built to work efficiently within these rules, keeping your data accurate without unnecessary delays.

The Challenge: Staying Within API Guidelines

Exact Online’s API rules set a limit on:

  • How many requests can be made per minute
  • How many requests can be made per day


If too many requests are made too quickly, Exact Online will temporarily pause new requests until the limit resets. This safeguard helps maintain system performance for everyone.

Some integrations may require higher-tier packages to stay within these limits, but with App4Sales, most customers don’t need to upgrade — because our approach is designed to stay well within the standard limits.

Our Solution: Smart Synchronization

We’ve built our Exact Online integration to fully comply with these guidelines by:

  • Using sync endpoints provided by Exact Online.
  • Batch processing and using timestamps to fetch only recent changes.
  • Retrieving updates or deletions only after the full dataset is synced.

This approach means:

  • Smooth, uninterrupted synchronization
  • Fully up-to-date data between systems
  • No unnecessary package upgrades

Important to Know: Orders Are Always Prioritized

Even if you reach your daily API call limit, order submission is excluded from that limit. You can always place and process orders through App4Sales without interruption.

Do You Need Exact Online Premium?

With App4Sales, you typically don’t need to upgrade to Exact Online Premium solely because of API limits. The only time an upgrade may be necessary is if you require specific Premium-only features — such as endpoints that don’t have a sync option available.

FAQ – Your Questions Answered

Q: What happens if I reach my Exact Online API limit?
A: Your data sync may pause until the limit resets, but our system is designed to avoid hitting these limits in the first place.

Q: Can App4Sales prevent API limit issues?
A: Yes. Our integration works efficiently with Exact Online’s API guidelines to minimize usage while keeping data current.

Q: Will my orders stop if I hit the API limit?
A: No. Order submission is excluded from the limits, so orders will still go through.

Q: Do I need to upgrade to Exact Online Premium?
A: Not for API capacity alone. You’ll only need Premium if you want specific features without sync endpoints.

Q: How do I know my data is up-to-date?
A: Our integration uses scheduled syncs and timestamps to ensure we only fetch the data changes you need.
