Role of [NERD-METHOD]
Architecture and implementation of the first-party bridge, Telegram and CRM binding, event rules and operational verification.
Connect a CRM stage back to the original ad visit
Preserved context before Telegram and linked it to the enquiry and CRM. Feedback was limited to the confirmed Contacted stage.
Meta API acceptance is dated 27 May 2026. Payment and campaign attribution are unproven.
Evidence as of: 2026-05-27
The original task
In a Telegram-first service, the ad visit, bot conversation and sales work lived in different systems. The task was to preserve the origin of an enquiry and send Meta a signal for one selected CRM stage. A button click and a manager working the enquiry had to remain separate facts.
What we built
A first-party redirect was placed before Telegram. It saves advertising context in a server record and passes a compact token to the bot. The bot binds that token to the subsequent enquiry. The link carries into CRM and is used when handling its webhook, without relying on approximate event timestamps.
How we defined the outcome
CRM stages pass through an explicit mapping. The confirmed active configuration is limited to Contacted. The sender handles original event time, repeated delivery, events that are too old and delivery-attempt records. This separates the business stage from a technical webhook retry.
What was verified
Verification covered context storage before Telegram, the enquiry-to-CRM link and event feedback. Historical project records document Meta API acceptance of a production event on 27 May 2026 without a test event code. This confirms technical event delivery; it does not by itself establish campaign attribution or payment.
What the evidence covers
The evidence is historical. It does not establish current service health, campaign settings, QualifiedLead, Scheduled or Purchase. Contacted denotes the selected enquiry-handling stage; it does not establish qualification, a contract or payment. No sales lift, CPA or ROAS is claimed.
What the project retained
Ownership of the attribution record, the token-to-enquiry link, CRM mapping, diagnostic records and operating instructions. This contract makes one agreed business stage traceable from the original visit to external event acceptance.
