I need a third-party API fully wired into both my existing web application and its companion mobile app. The goal is for users to enjoy identical, real-time functionality across platforms—authentication, data retrieval, and data submission—without noticing the underlying bridge. Here’s the shape of the work: • Analyse the current codebases, map the points where the API needs to plug in, and identify any refactoring required for clean integration. • Build the calls, handle errors gracefully, and surface meaningful messages to the UI. • Ensure secure storage of tokens/keys and respect rate limits set by the provider. • Deliver concise, developer-friendly documentation (endpoints used, response formats, setup steps) so future updates are painless. • Provide a short walkthrough video once everything is merged and tested. I’ll judge success by seeing the web and mobile builds exchanging live data through the new endpoints with no console errors, no failed test cases, and performance remaining on par with the current release. When you reply, share links or repos that show similar API integrations you’ve completed—real examples speak louder than bullet-point résumés. If any additional access keys or sandbox accounts are needed, just list them and I’ll supply them right away.
