Overview
Nitin investigated a third-party developer report about URL encoding and found repeated encoding in the integration. He made the function idempotent so the issue would not recur across similar developer implementations.
The Story
Nitin investigated a forum report from a third-party developer whose URL encoding function was failing. The immediate issue came from encoding being applied both manually and by default behavior.
Rather than asking the developer to rewrite their integration, he considered the broader support burden. Similar implementations could produce the same failure, and individual outreach would not resolve the underlying product behavior.
He implemented idempotency in the URL encoding function so repeated calls would remain safe. After shipping, the team used the original developer response and the volume of related support queries to assess the change.
The original developer no longer needed to alter their code, and related queries declined sharply.
