I need a clean, reliable bridge between the Meta Marketing/Conversions API and my current CRM (it’s a proprietary platform, not Salesforce, HubSpot, or Zoho). The main objective is sharper customer targeting inside Meta Ads by syncing two data sets from the CRM—demographic fields and key behavioural events—into custom audiences. Here is what the work involves: • Map and push demographic and behavioural data from the CRM to Meta via the Marketing or Conversions API, ensuring every user record stays hashed and privacy-compliant. • Configure the flow so updates in the CRM propagate to Meta in near-real-time (webhooks or scheduled jobs are fine as long as latency stays low). • Validate that audiences created with the synced data are recognised by Meta Ads Manager and can be segmented, excluded, or expanded without errors. • Document the integration steps and deliver source code or low-code scripts so future tweaks are straightforward for an in-house dev. Acceptance will be based on a test campaign that shows the new, CRM-fed audience populating correctly and matching rates inside Meta’s diagnostics above 90%.

Hello Sir, I am also from banglore. My approach: build a middleware service that maps your CRM's demographic and behavioural fields to Meta's Custom Audience and Conversions API schemas, syncing via webhooks where your CRM supports them, falling back to scheduled polling where it doesn't — keeping latency low either way. Match rate above 90% depends heavily on which identifiers you hash and send (email + phone together outperforms either alone), so I'd tune that mapping specifically against Meta's diagnostics during testing rather than treating it as a fire-and-forget config. Delivered with documentation and source code so your in-house dev can extend it. Question: does your CRM expose webhooks, or would this need polling? I have worked here with more than 130+ clients. Available immediately. Best regards, Vishruth

Hi, I can build a secure integration between your proprietary CRM and the **Meta Marketing/Conversions API**, enabling near real-time syncing of demographic and behavioral data to Meta Custom Audiences. The integration will securely hash customer data, support webhooks or scheduled syncs, maintain high match quality, and ensure audiences are ready for targeting, exclusions, and lookalike creation in Meta Ads Manager. I'll also provide clean, well-documented source code and a deployment guide so your team can easily maintain or extend the integration. I'm ready to review your CRM API and discuss the best architecture to achieve reliable syncing with a 90%+ match rate. Best regards, Abhishek

I have had extensive experience working with API integrations, especially in the realm of marketing and CRM systems. Your project seeking an integration between Meta's Marketing and Conversions API and your proprietary CRM sounds right up my alley. I've successfully integrated a variety of APIs, including those specific to targeted audience manipulation, and this project has the potential to further showcase my expertise. To ensure data privacy in compliance with GDPR regulations, I will leverage my skills in hashing user records and utilizing privacy-compliant methods of data transfer. I understand the importance of near-real-time updates and have worked with both webhooks and scheduled jobs to accomplish this. As your project requires documentation and handover for any future changes, I prioritize providing clean and thorough documentation that ensures smooth operations for your in-house dev team. What sets me apart is not just my technical aptitude but also my commitment to results. I see that you aim for population rates above 90% on Meta’s diagnostics - this aligns with my own dedication to delivering high-quality solutions that meet client expectations. My proficiency in Meta Ads Manager will enable me to validate that segments, exclusions, and expansions based on the synced data work seamlessly on the platform. Choose me; choose a solution-oriented developer who doesn't compromise on excellence.

Hi, I hope you're doing well. I understand you're looking to build a reliable integration between your proprietary CRM and Meta’s Marketing/Conversions API to improve audience targeting through accurate customer data synchronization. The key requirement is a secure and maintainable data pipeline that keeps demographic and behavioral information updated while following Meta’s privacy and hashing requirements. I will design and implement the integration flow to securely map CRM data, normalize and hash user information, and send relevant audience and event data to Meta through the appropriate APIs. I will configure near real-time synchronization using webhooks or scheduled processes depending on the CRM capabilities, validate audience creation and matching performance inside Meta Ads Manager, and provide clear documentation with source code for future maintenance and enhancements. My focus is on delivering a secure, dependable API integration with accurate data handling, strong error management, clear documentation, and a smooth handover so your team can confidently manage the solution long term.

Mapping and syncing non-standard CRM data to Meta’s Marketing or Conversions API is only reliable if your CRM exposes clean, granular webhooks or a query API for user and event changes. Demographics are usually straightforward, but behaviour events often need case-by-case mapping for Meta to accept them. I built a direct Meta Conversions API bridge for a bespoke ERP last quarter—privacy-safe hashing, live sync using cron plus webhook fallback, full field mapping, and a test campaign that hit 92% match. Node.js for the connectors, privacy salted in-memory, doc included. Does your CRM allow outbound webhooks per record/event, or will I need to poll for diffs? I can start this week if you share schema samples. Pradeep

The hard part of CRM to Meta sync is not the API call, it is keeping hashes consistent and audiences fresh without leaking raw customer data. That is where this build earns its keep. The flow: map your demographic fields and behavioural events to Meta's schema, hash every identifier before it leaves your system, push via the Conversions and Marketing APIs, then wire near-real-time updates through webhooks from your CRM with a scheduled reconciliation job as the safety net. Audience match rates validated against Meta's own diagnostics before handover. I run Meta platform integrations in production for a consumer brand daily, so the privacy and freshness traps here are familiar ground. Documented handover so your team owns it after. Does your CRM expose webhooks today, or do we start with scheduled sync?

Hi, I can build a clean integration between your proprietary CRM and Meta Marketing/Conversions API to sync demographic fields and behavioral events into Meta custom audiences securely. The best solution is to first review your CRM data structure, available API/webhook access, customer identifiers, and event types. Then I’ll map the required fields, hash sensitive user data before sending, create the sync flow using webhooks or scheduled jobs, and validate that the CRM-fed audiences appear correctly inside Meta Ads Manager. I’m comfortable with API integrations, CRM data mapping, Meta Marketing API, Conversions API, custom audiences, event syncing, data hashing, privacy-safe workflows, webhook automation, scheduled jobs, logging, and integration documentation. Deliverables will include: * CRM-to-Meta data mapping * Demographic data sync * Behavioral event sync * Hashed customer data handling * Webhook or scheduled sync flow * Custom audience setup support * Error logging and retry handling * Audience validation in Meta Ads Manager * Source code or low-code scripts * Setup and handover documentation I’ll focus on a reliable, privacy-conscious integration that keeps audience data updated and easy for your in-house team to maintain later.
