How an integration connects two business apps
This guide explains, in plain terms, how a connection between two common business apps is designed. It uses a worked example and three decisions that any team can review before turning an integration on.
01
Step one: choose the trigger and the action
Every integration begins with a trigger in the first app and an action in the second. Take a worked example: when a customer submits a quote request form, a new contact should appear in the sales team's customer list. The trigger is the form submission; the action is creating a contact. Write this as one sentence before configuring anything. If the sentence needs the word and more than once, split it into separate connections. A single clear trigger and action makes the setup easier to test, explain to colleagues and switch off later.

Step two: map the fields deliberately
Next, decide which piece of information in the form belongs in which place in the list. Name goes to name, email to email, and the free-text message to a notes field. Check formats, because a form may collect a full name while the list expects first and last names separately. Decide what happens when a field is empty and whether an existing email should update the current contact instead of creating a duplicate. Mapping is where most integration problems originate, so review it with the person who uses the list every day.

Step three: test, observe and assign an owner
Run a few test submissions and confirm each appears correctly in the list, including awkward cases such as long messages or unusual characters. Then review the activity record after the first real week to see whether anything failed or arrived twice. Name one person responsible for the connection, and note what to do if either app changes its settings or login. Finally, record how to pause it. An integration is ongoing work between two systems, so a clear owner and a simple review habit keep it dependable over time.
