A lead from a Facebook or Instagram form becomes a counterparty and a request in 1С/BAS, and the sale from 1С/BAS tells the ads which leads were worth it
Leads come from Facebook and Instagram forms, but they land in a spreadsheet that someone downloads from the ads cabinet once a day. By the time the manager calls, the person has forgotten the ad; by the time the accountant sees the sale, nobody remembers which campaign brought it. The 1С/BAS ↔ Meta Lead Ads pair closes the loop: each lead appears in 1С/BAS as a counterparty and a request within a minute, with the campaign and form named, and a sale posted in 1С/BAS is sent back to Meta so the ads learn which leads turn into money. Below: what exactly moves, which scenarios we cover and which capabilities of both systems we rely on.
Before the marketer downloads the leads spreadsheet from the ads cabinet every evening, and the manager calls the next morning to people who no longer remember the ad.
After the lead is in 1С/BAS within a minute with the product from the form, and the manager calls while the interest is warm.
Before the cabinet shows the number of forms per campaign, and the accountant shows sales in total; nobody can put the two together.
After every sale in 1С/BAS carries the campaign name, and the weekly report shows which campaigns brought money, not just forms.
Before Meta shows the ad to people who like filling in forms, and half the leads never pick up the phone.
After sales posted in 1С/BAS go back to Meta as quality leads, and the ads are shown to people who resemble those who bought.
Before a regular client fills in a form from every new ad, and each time a new card is created and a different manager calls.
After the lead is matched by phone to the existing counterparty in 1С/BAS, and the request lands with the manager who already knows the client.
For those who want to check: each point links to the official documentation page it comes from.
The official BAS support portal documents its integration technologies under the title «Технології інтеграції 1С:Підприємства 8.3» — BAS is built on the 1C:Enterprise 8.3 platform.

Source: developers.facebook.com ↗ checked 2026-09-28There are two ways to collect leads: reading them in bulk a few times a day, or being notified about each new lead the moment it is submitted — Meta recommends the second for anything more frequent.
Source: developers.facebook.com ↗ checked 2026-09-28Leads from an ad shown on Instagram still belong to the Facebook Page, so one connection to the page covers both networks.
Source: developers.facebook.com ↗ checked 2026-09-28Information about which leads turned out to be quality leads can be sent from the CRM back to Meta, and Meta uses it to optimise the ads for quality rather than volume.
Source: developers.facebook.com ↗ checked 2026-09-28The limits come from both systems. The connection to Meta has to pass their review for two permissions; until then it works in development mode for your Page only, and the review takes time that we do not control. Someone with administrator rights on the Facebook Page has to grant the access. 1С/BAS does not know about ads on its own: the campaign name lives in the lead as a text field, and the sales-by-campaign report is built from that field. 1С/BAS is on the official prohibited software list: we do not take projects for state bodies, critical infrastructure or systems with state data, and with private businesses we discuss the risk openly.
Three steps from a first message to work on your project.
Describe the task in the form — in text or by voice. Budget and timing are optional.
A developer studies the brief, asks about anything unclear and sends an estimate.
Once scope and price are agreed, the work begins.
