Think Twice: Customizations That Break Your Integration

When you build data integrations between applications, small details are very important. If you miss them, you might need to rebuild parts of the integration later, which costs time and money.

One common case is when a team asks the client to make custom changes in their system to help sync the data. This might work in the short term, but it can also bring risks if you don’t think it through.

Before you suggest or require such changes, ask yourself:

  1. Will this work for all clients, or just a few?
  2. Does it require an extra license?
  3. Can the client do it themselves, or will they need outside help (for example, a vendor)?
  4. Is it supported in every version of the app?
  5. Could this setting be removed or changed later in the app?

Why this matters:

  1. Scalability –> integrations should work for many clients, not only special cases.
  2. Maintainability –> customizations can break after upgrades and create extra work.
  3. Risk reduction –> planning early helps avoid broken syncs and unhappy clients.

By asking these questions up front, you can save a lot of rework and keep integrations stable in the long run.
