TL;DR

• Cello integrates with Salesforce via a native Apex Trigger on the Opportunity Object (your pipeline records). No Zapier connector or middleware required.
• The trigger fires when an Opportunity reaches the Proposal/Price Quote stage and the Cello_UCC__c custom field is populated.
• Setup takes four steps: add the Cello_UCC__c custom field to the Opportunity Object, deploy the Apex Trigger, configure the handler class conditions, and validate in Salesforce Sandbox before production deployment.
• Native Apex integration sends referral attribution data to the Cello API in real time, eliminating polling delays and field-mapping errors.

A RevOps Guide to Integrating Cello Referrals with Salesforce Apex Triggers (2026)

Most referral platforms that claim 'Salesforce integration' deliver it through a Zapier connector. Cello does not. Cello's Salesforce integration is native Apex code, it lives inside your Salesforce org, fires in real time on every qualifying Opportunity update, and sends referral attribution data directly to the Cello API with no middleware, no polling delay, and no third-party dependency. As of April 2026, Cello is the only referral platform to publish a dedicated, native Salesforce Apex Trigger integration. No competitor offers this.

Referred customers have a 16% higher lifetime value than non-referred customers (Schmitt, Skiera & Van den Bulte, Journal of Marketing). That advantage only shows up in your pipeline reporting if attribution is accurate, and attribution is only accurate when Salesforce is the single source of truth. This guide shows RevOps and Sales Ops teams exactly how that connection works, and why every alternative falls short.

Why Cello is the Only Referral Platform with a Native Salesforce Integration

Cello is the only referral platform with a published, native Salesforce integration built on Apex Triggers, not a Zapier connector, not a managed package, not a webhook workaround. That matters because connector-based integrations have four failure points that RevOps teams encounter at scale: polling delays before attribution fires, field mapping errors when Salesforce schema changes, no guarantee that third-party middleware executes, and a separate task queue that drops records under bulk load. Native Apex eliminates all four. The integration logic lives inside Salesforce itself. It fires synchronously, handles 200-record batch updates natively, and reads Salesforce fields directly with no translation layer.

What You Need Before You Start

The Cello Salesforce Apex Trigger integration requires four prerequisites: a Cello Scale or Enterprise plan, Salesforce Enterprise or Unlimited Edition, the Cello_UCC__c custom field on the Opportunity Object, and an active Salesforce Sandbox for validation. Confirm each item below before beginning setup.

1. A Cello account on the Scale or Enterprise plan
2. Salesforce org on Enterprise Edition or Unlimited Edition
3. The Cello_UCC__c custom field created on the Opportunity Object: this is the field Cello uses to store the referral tracking code. Setup instructions are in the next section.
4. A Salesforce Sandbox org for testing

How the Cello Salesforce Integration Works (No Middleware Required)

The Cello Salesforce integration runs entirely inside your Salesforce org as native Apex code. There is no third-party connector to maintain, no Zapier workflow to monitor, and no external API layer that can drop records. The full technical setup, with verbatim Apex code, is available. Here is what each step achieves for your RevOps team:

1. Step 1: Add a single custom field (Cello_UCC__c) to the Salesforce Opportunity Object. This is the only schema change required. It stores the unique referral code Cello assigns to each referred user, connecting your Cello referral data to your Salesforce revenue records.
2. Step 2: Deploy the Apex Trigger on the Opportunity Object. The trigger fires automatically after every Opportunity update, real time, no polling interval, no external queue. It delegates to a handler class that applies the attribution logic.
3. Step 3: The handler class checks two conditions before firing: the Opportunity must reach the qualifying pipeline stage, and the Cello_UCC__c field must be populated. Only referred Opportunities trigger an attribution event. Non-referred pipeline is never affected.
4. Step 4: Test in Salesforce Sandbox before going live. Validate that the attribution event appears in the Cello dashboard with a 200 API response. Cello's documentation requires sandbox validation before production deployment to protect live revenue data.

What RevOps Teams Can Track After Integration

Once the integration is live, Salesforce becomes your single source of truth for referral revenue. RevOps teams gain three reporting capabilities that are impossible with connector-based integrations, because those integrations can drop records, fire on delay, or miss bulk updates entirely:

• Referred pipeline by stage: filter any Salesforce Opportunity report by Cello_UCC__c != null to isolate referral-sourced pipeline at every stage.
• Referral-influenced ARR: build a Salesforce report showing Closed Won Opportunities where Cello_UCC__c is populated. This is your referral-influenced ARR figure.
• Automated reward qualification: when the Apex Trigger fires, Cello receives the referral code and Opportunity ID, allowing Cello to automatically qualify and trigger the reward without any manual intervention from the marketing or growth team.

These reporting capabilities are only reliable when attribution fires synchronously, as it does with native Apex, and not through a polling-based connector. Zapier-based integrations introduce delays of up to 15 minutes on free plans (1–2 minutes on paid plans) before attribution fires, and drop records when field mappings break on Salesforce schema changes. Cello's native integration has one failure point: the Cello API. Everything else runs inside Salesforce itself.

Cello vs. Zapier-Based Salesforce Integrations: Why Native Wins

Most referral platforms that claim 'Salesforce integration' deliver it through a Zapier workflow: Salesforce triggers a webhook event, Zapier catches it, Zapier maps fields, Zapier calls the referral tool's API. That chain has four failure points that every RevOps team eventually encounters.
