Why teams connect AWS S3 and Lusha

Get the data locked inside Lusha into AWS S3 as live tables, and send results back where Lusha can use them, without writing a pipeline.

Lusha is a read-only source: Stacksync reads its data in real time and delivers it into AWS S3, so AWS S3 always reflects the current state of Lusha — without exports, scripts, or schedulers.

Whatever Lusha is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Common use cases

  • Append firmographic company data to account records before territory or scoring runs.
  • Build prospecting lists from Lusha search results and sync them into the CRM as leads.
  • Export synced operational data to S3 as files feeding a data lake or downstream batch jobs.
  • Trigger incremental sync runs from S3 event notifications when new files land in a prefix.

Analytics on Lusha's data

Records and events from Lusha land in AWS S3 as queryable tables, current within seconds and ready to join with the rest of the warehouse.

Cross-tool reporting

Combine Lusha's data with data from every other synced system to answer questions no single tool can.

Where Lusha accepts updates: operational write-back

Segments, scores, or reference values computed in AWS S3 sync back onto records in Lusha, putting analysis where the work happens.

What you can sync between AWS S3 and Lusha

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

AWS S3 objects Lusha objects
Access Points Scoped network endpoints used to grant a sync narrow access to a bucket. Company Profiles Firmographic records (industry, size, location) appended to account or company rows.
Multipart Uploads The mechanism used to write large export files reliably. Email Addresses Work emails written into CRM contact fields during enrichment.
Buckets Top-level containers a sync targets; region and policy are set at this level. Phone Numbers Direct-dial and mobile numbers appended for outbound calling workflows.
Objects The stored files (CSV, JSON, Parquet); syncs read them as datasets or write exports into them. Prospecting Results Search-based lists of people and companies matching filters, used to seed lead lists.
Prefixes Key-name paths used to partition synced datasets, since S3 has no real directories. Bulk Enrichment Requests Batch lookups that enrich multiple records per request, used to backfill large contact lists rather than one-off calls.
Object Metadata System and user-defined metadata read alongside object contents. Person Profiles Contact-level enrichment results (work emails, phone numbers, title, company) returned per lookup.

How the AWS S3 and Lusha connectors work

AWS S3

Integration surface
REST API (the S3 API), accessed directly or through AWS SDKs
Authentication
AWS IAM credentials with SigV4 signing; commonly a role scoped to specific buckets and prefixes
Change detection
S3 Event Notifications on object create/delete delivered to SQS, SNS, Lambda, or EventBridge; list-based polling as a fallback
Capabilities
read · write · webhooks
Rate limits
Request throughput scales per prefix; sustained high-volume workloads should spread keys across prefixes

Lusha

Integration surface
REST API
Authentication
API key
Change detection
Not event-driven; data is fetched on demand per lookup, so syncs poll or trigger enrichment when source records change
Capabilities
read
Rate limits
Lookups consume credits and are subject to the platform's API rate limits.
