Meta (Facebook / Instagram) Integration

Connect your Everflow account to Meta's Conversions API to automatically send conversion data to Meta, improving ad optimization and performance tracking while gaining powerful analytics to scale winners and kill losing campaigns.

Overview

When you connect Meta (Facebook) to Everflow, you unlock better ad performance and complete campaign visibility. Here's what you get: Everflow automatically sends your conversion data to Meta using their Conversions API, which means Meta's algorithm receives real conversion information to optimize your campaigns. Plus, you get granular tracking and analytics to quickly identify winning campaigns and eliminate money-losing ads.

This integration helps you build accurate audiences faster on Meta while giving you the data insights needed to scale profitable campaigns and cut losses quickly.

This integration refers to what was previously called the Facebook integration.

Prerequisites

Before setting up the Meta integration, ensure you have:

A Meta Business Manager account with admin access
An active advertising account in Meta
A partner and offer created in Everflow
JavaScript tracking implemented (click and conversion scripts on your landing and thank you pages)

A Step-By-Step Guide

Use the Conversions API Gateway method to generate your access token, as this is the recommended and tested approach.

Generate Your Meta Access Token (Conversions API Gateway)

Navigate to Meta Ads Manager → Events Manager

Select your Meta Pixel from the data sources

Go to Settings → Conversions API

Click Generate access token

Copy and save the token immediately - you won't be able to see it again once you close the window.

Create a Partner and Partner User

Set up a dedicated partner for Meta traffic:

In your Everflow Core Platform, go to Partners → Manage

Click Partner

Name it "Meta" or "Meta Ads" (this groups Facebook and Instagram traffic together)

Save the Partner

Create a Partner User for this partner

Note the Partner login credentials

Why this matters: Creating a separate Meta partner helps you filter paid vs organic traffic from Facebook and Instagram, which is key to understanding your funnel's full performance impact.

Connect Meta Integration (Partner Side)

Now switch to the Partner Platform to add the Meta integration:

Log into your Everflow Partner Platform using the partner user credentials or impersonating them

Go to Company Settings → Integrations

Click Add Business on the Meta card

Fill in the form:

Business Name: Choose any name you want

Access Token: Paste the token from Step 1

Click Add

Configure Meta Postbacks (Core Platform)

Switch back to your Core Platform to set up the postback:

In your Everflow Core Platform, go to Integrations → Media Buying → Meta

Click Connect Integration (this redirects you to the postback setup form)

Configure these fields:

Postback Level: Select "Specific" and choose your offer

Meta Business: Choose the business you created in Step 3

Meta Pixel: Select your Pixel ID

Meta Event Name: Choose your primary conversion event (usually "Purchase" for e-commerce or "Lead" for lead gen)

Action Source: Enter where conversions happen (see Meta's documentation)

Event Source URL: Add the webpage URL where conversions occur

Set Up Your Conversion Goal

E-commerce brands: Purchase
Lead generation: Lead
App companies: App Install

Optional: Add Purchase Data (For E-commerce)

Click Add under Meta Custom Data

Add Currency with value {offer_currency}

Click Add again

Add Value with value {payout_amount}

Add User Data for Better Audience Matching

Scroll to Meta User Data

Click Add

Select Fbc as Data Field

Enter this value: fb.1.{timestamp}.{fbclid}

Add as many additional data fields as possible (email, phone, etc.) to improve match quality

Pro Tip!

More user data fields = faster audience matching and better Meta optimization.

DATA HASHING FOR PRIVACY COMPLIANCE

When sending personal information like emails or phone numbers to Meta, you may need to hash the data for privacy compliance. Everflow supports automatic hashing with these formats:

{adv1>LC_SHA256} - Converts to lowercase first, then applies SHA256 hashing
{adv2>LC_SHA256} - Converts to lowercase first, then applies SHA256 hashing
{sub1>LC_MD5} - Converts to lowercase first, then applies MD5 hashing

Available hashing options: SHA1, SHA256, MD5. Use LC_ prefix (like LC_SHA256) when you need to convert data to lowercase before hashing - this is especially important for email addresses to ensure consistent hashing.

Advertisers would typically pass email data in adv1 and phone numbers in adv2, which can then be hashed and sent to partners using these macros.

Set Up Funnel Events

Don't stop at one conversion event. Set up your full marketing funnel to help Meta understand your audience better:

Recommended E-commerce Events:

View Product

Add to Cart

Initiate Checkout

Purchase (primary goal)

Recommended Lead Gen Events:

View Landing Page

View Pricing

View Demo Page

Email Click

Lead (primary goal)

To add these events:

Go to Partner -> Postbacks

Find the Events table (second table after Conversions)

Add each funnel event with the same Meta configuration

Sending your full funnel to Meta allows faster audience identification and enables retargeting campaigns later.

Set Up Campaign Tracking

Use Everflow's Tracking Link Generator to create trackable links:

Go to Tools → Tracking Link Generator

Select your Offer

Choose your Meta partner

Configure Sub IDs to track performance (just examples):

Sub ID 1: Campaign name or sale type (e.g., "BOGO", "Summer Sale")

Sub ID 2: Landing page or creative identifier (e.g., "Quiz", "Ad3")

Good To Know

Include campaign name, landing page, and creative info in your Sub IDs to quickly identify what's working.

Processing Time: While conversions are sent in real-time, Meta may take up to 4 hours to process offline conversions

FAQ

Will Everflow track conversions accurately even if Meta's reporting shows different numbers?

Yes. Everflow tracks conversions through first-party cookies and direct server calls with high accuracy. We also have backup systems that record conversions even if users delete cookies. Our transparent reporting shows exactly how each conversion was attributed.

How quickly will I see improvements in Meta performance?

Most users see improved campaign performance within 24-48 hours as Meta's algorithm receives better conversion data. Full optimization typically occurs within 7-14 days of consistent data flow.

Can I track multiple offers with the same Meta integration?

Yes, but set up separate postbacks for each offer to maintain clean attribution and easier performance analysis.
