Integrations & technical
What is an API?
An API (Application Programming Interface) is an interface that lets two software systems exchange data automatically, without manual intervention.
How does an API work?
An API defines a set of rules and access points (endpoints) that let one application send requests to another and receive a structured response back, typically in JSON format.
Why does an API matter for scheduling software?
It removes the need to manually re-enter data between systems and lets you connect scheduling software to an ERP, HRIS, or CMMS already in place at your company.
Real-world example
Through an API, a company can have a new task automatically created in its schedule the moment a new order is logged in its ERP — with zero manual steps.
What are the pros and cons of an API?
An API cuts down data-entry errors and speeds up how fast systems talk to each other. Its limit: setting one up typically requires development skills or the help of an integration partner.
API vs. ready-made connector
| API | Connector | |
|---|---|---|
| Technical skill required | Development needed. | Configuration, no code. |
| Flexibility | High, fully custom. | Limited to pre-built use cases. |
| Setup time | Longer. | Fast. |
Key takeaways
- An interface for automatic data exchange between two software systems.
- Works through structured requests and responses, often in JSON.
- The backbone of integrations between scheduling, ERP, HRIS, and CMMS.

Frequently asked questions
Do I need to be a developer to use an API?
Setting one up typically requires development skills, but once connected, day-to-day use is invisible to end users.
What's the difference between an API and a connector?
A connector is a ready-made integration built on top of an API, requiring no custom development.
Does Visual Planning offer an API?
Yes, Visual Planning offers an API for connecting the schedule to third-party systems like an ERP, HRIS, or CMMS.
Is an API secure?
Yes, as long as it uses authentication (API keys, tokens) and an encrypted connection (HTTPS), which are standard for this kind of integration.
