The brand
StarzPlay is one of the leading subscription streaming services in the Middle East and North Africa, acquiring subscribers at scale through paid media, with free trials as the key conversion event.
The problem
Free-trial signups happen across a mix of browsers and devices where pixel-only measurement leaks. Meta was attributing fewer trials than the subscription system recorded, so campaign optimization was working from an incomplete picture and the growth team could not trust channel-level ROAS.
What Datahash did
Datahash deployed Meta Conversions API through Signals, sending trial-start and subscription events server-side with SHA-256 hashed match keys and event_id deduplication against the existing Meta Pixel. The setup ran in parallel with the pixel from day one, so there was no measurement gap during rollout.
Results
StarzPlay measured an 11.7% increase in attributed free-trial subscribers with CAPI. Those recovered conversions now feed Meta’s delivery models, improving who the campaigns reach on every subsequent auction.
