The brand
Puretech Digital is one of India’s leading independent digital agencies, running paid media programs for large advertisers across categories where audience privacy and data handling are under constant scrutiny.
The problem
As an agency, Puretech had to solve server-side measurement for multiple clients at once, each with its own stack and its own compliance requirements. Building and maintaining bespoke Conversions API integrations per client would have been slow, expensive, and hard to keep consistent.
What Datahash did
Datahash gave Puretech a repeatable Meta CAPI setup on Signals: server-side event delivery with SHA-256 hashing at source, no PII stored on the host server, and pixel deduplication as standard. The same privacy-safe pattern now rolls out per client in a fraction of the time a custom build would take.
Results
Puretech runs Meta CAPI in production across client campaigns, executing with the efficiency the agency model demands while keeping audience privacy and security at the front of every implementation.
