API
An application programming interface (API) defines how software can request information or actions from other software. In business automation, it can be used, for example, to search for a customer, update an order, or create a task without performing those actions manually on screen.

In business automation
In automation, an API is a structured way to ask a system to read or change information. It enables a connection that does not depend on the location of a button on screen, but it is still subject to permissions and service limits.
Examples
These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.
Business process example
A consultation form is submitted on a website. The process uses an API to search for a customer by email address in the CRM, updates an existing record or creates a new one, and saves the customer ID for follow-up.

- The HTTP Request node can call APIs even when no ready-made node is available for a service.
What to check
- Not every action available on screen is also available through an API. Check the actual action and fields before committing to a connection.
