CONNECTIONS / MongoDB

MongoDB + Datahash: your collections become events.

Order history and customer documents sit in MongoDB collections, often behind an application you already run. Signals reads them with a scoped query on a schedule you set and delivers hashed events and audiences to every major ad platform, with no export.

WHAT FLOWS THROUGH MONGODB

The signal MongoDB yields, and receives.

Every kind of signal that moves between MongoDB and the platforms, through one hashed, deduplicated route.

Offline conversions: Every scheduled pass filters a collection down to what changed, and those order and customer documents come out the other side as events, no export required.
Lead conversions: Change streams hand Signals only documents inserted or updated since the last pass, so a growing collection never means a heavier read.
Custom audiences: Every email and phone number in a matched document gets SHA-256 hashed before it moves anywhere else, so plaintext never leaves the read step.
Lead generation inbound: A collection's field names, however inconsistent across documents, still land in the right event fields once the visual mapper sees them.

FAQ

MongoDB questions, answered.

Does Datahash write to my database?

No. Signals authenticates with a role granted read access to the specific collections you choose, never write, update, or delete permissions. Scoping can go as narrow as a single collection, and because the role is fully revocable, removing it at any time leaves the rest of your MongoDB deployment untouched.

Is customer PII stored by Datahash?

Signals hashes emails and phone numbers with SHA-256 as soon as a document is read from the collection, so only hashed values travel any further. Datahash Cloud's host servers never store PII, only the hashed output that results. If data cannot leave your perimeter at all, a self-hosted Core deployment performs that same hashing step internally before delivery.

How often does the sync run?

Pick a cadence anywhere from every few minutes to once a day; change streams mean each run reads only documents inserted or updated since the last pass. That keeps query load on a MongoDB deployment flat even as a collection grows, and different collections can run on different schedules, so an orders collection can sync far more often than a slowly changing customer list.
