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.
Cookie Matching
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.
