We need a skilled developer with deep knowledge of the Google Tag Manager (GTM) API and Facebook Ads API/Facebook Pixel to troubleshoot and fix our programmatic advertising pipeline. Our team has built a system that automates Google Ads campaigns, sets up GTM tags programmatically via the GTM API, and places these tags on automated landing pages to track conversions. We’re also using the Facebook Pixel to retarget audiences from these campaigns on Facebook, but something in the pipeline isn’t working as expected.
Your role will be to dive into our existing code, analyze the setup, and identify why the data isn’t flowing correctly between GTM, Google Ads, the Facebook Pixel, and our ad platforms. We’re not looking for a full integration build—just expert debugging and recommendations to get our current system running smoothly.
Responsibilities:
Analyze the Existing Pipeline:
Review our code that uses the GTM API to create and manage tags, triggers, and variables for tracking on landing pages.
Examine how the Facebook Pixel is implemented and configured within our system (via GTM or otherwise).
Troubleshoot Issues:
Identify why audience data from Google Ads (tracked via GTM) isn’t properly syncing for retargeting on Facebook.
Determine why conversions tracked by GTM tags on landing pages aren’t reflecting correctly in Google Ads and/or Facebook Ads.
Debug & Recommend Fixes:
Pinpoint bugs, misconfigurations, or gaps in the pipeline (e.g., Pixel firing issues, API call failures, data mismatches).
Suggest actionable solutions to resolve these issues without requiring a full rewrite (unless absolutely necessary).
Testing:
Validate your findings by testing the pipeline and ensuring data flows correctly between GTM, Facebook Pixel, and the ad platforms.
Documentation:
Provide a clear report of what’s broken, why it’s failing, and how to fix it, including any code snippets or configuration changes needed.
Skills & Qualifications:
Strong understanding of the Google Tag Manager API (e.g., tag creation, triggers, variables) and how it integrates with tracking systems.
Expertise with the Facebook Ads API and Facebook Pixel, including how they handle audience retargeting and conversion tracking.
Proficiency in debugging complex workflows involving RESTful APIs, ideally in Python.
Experience analyzing and fixing issues in digital advertising pipelines (e.g., pixel firing, audience syncing, conversion tracking).
Familiarity with Google Ads API is important, as it ties into our broader system.
Ability to read and understand existing codebases quickly.
Excellent problem-solving skills and a methodical approach to troubleshooting.
(Optional) Experience with landing page tag implementation or front-end debugging.
Deliverables:
A detailed diagnosis of why our GTM-Facebook Pixel pipeline isn’t working.
Specific recommendations (and code/config fixes if applicable) to resolve the issues.
A test confirming the pipeline works as expected after applying your fixes.
A concise report documenting the problems and solutions.
Project Details:
Duration: 1-2 weeks
Budget: [Insert your budget range or state “flexible based on experience”]
Time Zone: Preference for overlap with GMT +8 (Singapore, Hong Kong)
How to Apply:
Please submit a proposal including:
Your experience troubleshooting issues with the GTM API and Facebook Ads API/Pixel (specific examples are a plus).
A past project where you debugged a similar advertising or tracking pipeline.
Your preferred tools or methods for analyzing and fixing API-related issues.
A brief outline of how you’d approach diagnosing our pipeline problems.
Your availability and estimated timeline.
We’re eager to work with a sharp-eyed expert who can get our pipeline back on track.
Looking forward to your application!
