CAPI Overview

Conversion APIs enable server-side event transmission to advertising platforms. Meta Conversions API and TikTok Events API bypass browser limitations, improving conversion tracking accuracy.

With iOS privacy changes and browser tracking restrictions, CAPI implementations have become essential for maintaining campaign optimization and measurement accuracy.

Meta Implementation

Setup Options

Meta offers multiple CAPI implementation paths: direct API integration, partner integrations, and manual configuration through Events Manager.

Partner integrations through Shopify, WordPress, and other platforms simplify implementation for common use cases.

Token Generation

Generate access tokens in Events Manager. System user tokens provide stable authentication for server implementations.

Event Configuration

Configure events matching your pixel events. Standard events like Purchase, AddToCart, and Lead have defined schemas.

Parameter Passing

Pass user parameters for matching: email, phone, external ID, and client IP. Hashed data enables matching while protecting privacy.

Our [paid advertising services](/services/digital-marketing/paid-advertising) include CAPI implementation.

TikTok Implementation

Events API Setup

Configure TikTok Events API through TikTok Ads Manager. Generate access tokens and configure pixel association.

Event Schema

TikTok Events API uses similar event structures to Meta. Standard events cover common conversion actions.

Integration Methods

Implement through direct API calls, partner platforms, or server containers. Choose based on technical capabilities and platform stack.

Pass TikTok click ID (ttclid) for attribution matching. First-party cookie storage maintains click ID availability.

Event Matching

Event Deduplication

Configure deduplication between pixel and API events. Event IDs prevent double-counting when both methods fire.

Match Quality

Monitor event match quality scores. Higher match rates improve attribution and optimization.

Data Enrichment

Enrich server events with data unavailable client-side. Customer database information can improve matching.

Hashing Standards

Follow platform hashing standards precisely. Incorrect hashing prevents matching and wastes implementation effort.

Real-Time vs Batch

Choose between real-time and batch event transmission. Real-time provides faster attribution; batch reduces API call volume.

Testing and Validation

Test Events

Use test event tools before production deployment. Both platforms offer testing interfaces for validation.

Event Matching Verification

Verify events match between pixel and API. Consistent event names and parameters enable proper deduplication.

Attribution Testing

Test attribution accuracy post-implementation. Compare reported conversions against backend systems.

Error Monitoring

Monitor for transmission errors. Failed events degrade tracking accuracy and require quick resolution.

Performance Impact

Measure performance impact on conversion campaigns. CAPI should improve optimization signal quality.

Optimization Strategies

Signal Quality

Maximize signal quality through complete parameter passing. More user data improves matching rates.

Event Priority

Prioritize high-value events in implementation. Purchase events matter more than page views for optimization.

Redundant Setup

Run pixel and API in parallel for redundancy. Either source can provide events when the other fails.

Advanced Matching

Enable advanced matching features where available. Enhanced parameters improve match rates further.

Regular Audits

Audit CAPI implementation regularly. Platform updates and website changes can break implementations.
