Why teams connect Apollo.io and Dun And Bradstreet

Run Apollo.io and Dun And Bradstreet side by side with the same accounts and contacts in both, whether they serve different teams or one is replacing the other.

Dun And Bradstreet is a read-only source: Stacksync reads its data in real time and delivers it into Apollo.io, so Apollo.io always reflects the current state of Dun And Bradstreet — without exports, scripts, or schedulers.

Two CRMs in one company is more common than anyone plans for: an acquisition brings its own system, regions or business units standardize differently, or a migration is under way and both are live. In every case, some of the same companies and people exist in both systems, and every day of manual double entry pushes the copies further apart.

Common use cases

  • 01 Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
  • 02 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 03 Pull D&B risk and credit signals (PAYDEX, Failure Score, D&B Rating) into a warehouse for credit-risk, vendor-risk, and third-party-risk analytics.
  • 04 Sync the D&B corporate family tree (parent and subsidiary DUNS) into the CRM so ABM and territory owners see full account hierarchies and roll pipeline up to the global ultimate.

Common sync patterns

Post-acquisition consolidation

Keep both CRMs accurate while the merged team decides on a target system, instead of freezing one and losing months of updates.

Migration with a parallel run

When one CRM is replacing the other, run both fully live until cutover, with no snapshot gap and no data freeze.

Divisional or regional split

Where each CRM serves a different team or region, sync just the shared accounts and contacts so handoffs and cross-sell work.

How changes propagate between Apollo.io and Dun And Bradstreet

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Apollo.io Dun And Bradstreet Interval-based propagation

DetectionStacksync polls Apollo.io for changes on an incremental schedule, reading only records changed since the previous pass. Polling on updated-at timestamps.

DeliveryDun And Bradstreet does not accept inbound record writes, so this direction carries requests rather than records: Dun And Bradstreet's output flows back as field updates on the originating Apollo.io records.

Dun And Bradstreet Apollo.io Interval-based propagation

DetectionStacksync polls Dun And Bradstreet for changes on an incremental schedule, reading only records changed since the previous pass. Polling via D&B Monitoring - register a portfolio of DUNS and pull change notices from the notifications endpoint (retained ~60 days).

DeliveryEach detected change is written to Apollo.io through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • Apollo.io: Rate limits and enrichment credits vary by plan; bulk endpoints are throttled separately from single-record calls.
  • Dun And Bradstreet: Per-contract transactions-per-second cap plus weekly/monthly/yearly quotas; exceeding TPS returns HTTP 429 with error 0045/0046 (0047 on spike arrest). Quotas reset on UTC boundaries.
