Google Data Manager API v1.9 adds call conversions with hashed phone numbers only
· 2d ago · Originally reported by PPC Land
Google released version 1.9 of its Data Manager API on November 4, adding support for uploading call conversions. Phone numbers must be hashed before submission, and each failed record now reports its position so developers and data partners can debug uploads. Lead IDs are accepted but cannot yet be used for attribution.
Why it matters
Call conversions are a key offline signal for advertisers, and the hashing requirement shows how Google is balancing measurement needs with privacy. The clearer error reporting reduces friction for partners pushing large conversion datasets.
Explain it like I’m new here
It's like the post office now accepts phone-call receipts as proof of a sale, but you have to scribble out the phone number first, and if a letter is rejected they now tell you exactly which one it was.
