Marketing agencies managing Meta Ads for multiple clients need a scalable, organised approach to Conversion API implementation. We design and build a multi-client CAPI architecture: a shared server-side infrastructure that handles event routing for all clients, per-client Meta pixel configuration, access token management, and monitoring — so your team can onboard new clients efficiently without rebuilding from scratch each time.

Frequently Asked Questions

A single server-side GTM container with per-client workspace or a shared server that routes events by domain. We design the architecture that fits your client count and growth plans.
Client isolation is enforced at the GTM tag level — each client's events only fire to their Meta pixel. We audit this isolation carefully during setup.
Each client's pixel access token belongs to their Business Manager. Your agency account can have access but tokens should be tied to client-controlled assets for security.
We build platform-specific CAPI configurations for each client, which are then managed centrally through your shared sGTM setup.
We set up server-side health checks, Events Manager automated rules for event drops, and a shared dashboard showing event volumes across all clients.
