Parameter

A variable passed to an API endpoint to control what data is returned or what action is performed. Example: `GET /contacts?status=active&limit=100&page=2` the parameters filter and paginate the response.

Expert insight

Hardcoding a parameter that should be configurable (a specific record ID, a hardcoded date range) is the single most common reason a "finished" workflow needs to be manually edited the next time someone wants to run it slightly differently, parameterizing the values likely to change turns a one-time script into a reusable workflow.

In a real workflow

A sub-workflow takes the client ID and date range as parameters, so the same report works for every client.

Common mistakes

  • Hard-coding values that should be parameters.
  • Unvalidated parameters causing wrong results.
