How to Set Up Predictive CAPI for Meta and TikTok with Angler AI
A step-by-step guide to connecting Angler AI to your Meta and TikTok ad accounts, enriching conversion signals with AI-predicted LTV data, and building high-LTV lookalike audiences — so ad platform algorithms bid on your best customers from day one.
Workflow steps
Connect your data sources to Angler AI
Log in to Angler AI and connect your ecommerce platform (Shopify, WooCommerce, or BigCommerce) and your CRM or CDP if applicable. Angler AI ingests your historical order data to build its predictive LTV model. The more purchase history you provide, the more accurate the predictions. Allow 24-48 hours for the initial model training on your specific customer base.
Install the Angler AI pixel on your site
Angler AIAdd the Angler AI JavaScript snippet to your website's <head> tag, or install via Google Tag Manager. This pixel captures on-site behavioral signals — page views, product views, add-to-cart events, and checkout initiations — and enriches them with Angler AI's identity graph to improve match rates when events are sent to Meta and TikTok. Verify the pixel is firing correctly using the Angler AI dashboard event debugger.
Confirm the Angler AI pixel is firing on all key pages: homepage, product pages, cart, checkout, and order confirmation. Check the event debugger for any missing or duplicate events before proceeding.
Connect Meta Conversions API (CAPI)
Angler AIIn the Angler AI dashboard, navigate to Integrations > Meta and authenticate with your Meta Business Manager. Select the ad account and pixel you want to enrich. Angler AI will route your conversion events through its enrichment layer before forwarding them to Meta CAPI — appending predicted LTV scores, identity-resolved email hashes, and phone numbers to each event. This improves your Event Match Quality (EMQ) score in Meta Events Manager, which directly impacts ad delivery efficiency.
After connecting Meta CAPI, check your Event Match Quality score in Meta Events Manager. A score above 7.0 is the target. If your score is below 6.0, verify that customer email and phone fields are being passed correctly from your ecommerce platform to Angler AI.
Connect TikTok Events API
Angler AINavigate to Integrations > TikTok in the Angler AI dashboard and authenticate with your TikTok Ads Manager. Select your pixel and ad account. Angler AI will enrich TikTok conversion events with the same LTV and identity data it applies to Meta, improving match rates on TikTok's Events API. This is particularly valuable for DTC brands running TikTok Shop or direct-response video ads where signal quality degrades significantly without server-side enrichment.
Verify TikTok Events API events are appearing in TikTok Ads Manager under Assets > Events. Confirm that Purchase and InitiateCheckout events are being received with a high match rate. Allow 24 hours after setup before evaluating match quality.
Enable LTV-based audience segmentation
Angler AIIn Angler AI's Audiences section, create a high-LTV customer segment using the predicted LTV scores from your trained model. Set a threshold (e.g., top 20% predicted LTV) and push this audience directly to Meta Custom Audiences and TikTok Custom Audiences. This segment can be used as a seed audience for lookalike campaigns, giving Meta and TikTok's algorithms a much higher-quality signal than a standard purchaser list.
Create a lookalike audience in Meta Ads Manager using your Angler AI high-LTV custom audience as the seed. Use a 1% lookalike for prospecting campaigns. Compare CPAs from this audience against your existing purchaser-based lookalikes over a 2-week test period.
Layer Triple Whale attribution on top
Triple WhaleWith Angler AI improving the quality of signals going into Meta and TikTok, use Triple Whale to measure the downstream revenue impact. In Triple Whale's Creative Cockpit, compare ROAS and CPA for campaigns running against your Angler AI high-LTV audiences versus your standard audiences. Triple Whale's multi-touch attribution will give you an accurate picture of which campaigns are driving actual revenue — not just reported conversions — so you can confidently scale the best-performing combinations.
In Triple Whale, create a custom report comparing ROAS, CPA, and new customer rate for: (1) campaigns using Angler AI high-LTV lookalike audiences vs (2) campaigns using standard purchaser lookalikes. Run for a minimum of 14 days before drawing conclusions.
Monitor and iterate
Angler AICheck Angler AI's dashboard weekly to review match rate trends, LTV model accuracy, and audience size changes. As you acquire more customers, retrain the LTV model monthly to keep predictions current. Use Triple Whale's alerts to notify you if ROAS drops below your target threshold, and cross-reference with Angler AI's signal quality metrics to diagnose whether the issue is creative fatigue, audience saturation, or signal degradation.
Set a Triple Whale alert for when 7-day ROAS drops more than 15% below your target. When triggered, check Angler AI's Event Match Quality score and audience size to rule out signal issues before adjusting creative or bids.
