Why teams connect Affinity and AWS S3

Sync Affinity into AWS S3 continuously and push warehouse results back onto CRM records, one two-way connection instead of two pipelines.

The CRM feeds the warehouse and the warehouse should feed the CRM: relationship data flows one way, and computed scores, segments, and customer context flow back. Most teams build the first half as a batch pipeline and never quite get to the second.

Stacksync does both with one connection. Notes, Interactions, Reminders, Lists from Affinity land in AWS S3 as live tables, updated within seconds, and columns computed in AWS S3 write back to fields in Affinity. There is no separate ETL and reverse-ETL stack to stitch together and no jobs to babysit.

Common use cases

  • Push enrichment data computed elsewhere into Affinity field values on list entries.
  • Keep introductions and relationship data from Affinity aligned with outreach tools used by the team.
  • Stage bulk loads for warehouses that ingest from object storage.
  • Archive change history from ongoing syncs as timestamped files for audit and replay.

CRM analytics on live data

Accounts, contacts, and activity from Affinity are queryable in AWS S3 moments after they change, so dashboards stop lagging the reality they describe.

Scores and segments back on the record

Lead scores, churn risk, or usage segments computed in AWS S3 appear as fields in Affinity, where the people working accounts actually see them.

A single customer view

Join Affinity's relationship data with billing, product, and support data in AWS S3 to build the customer picture the CRM alone cannot hold.

What you can sync between Affinity and AWS S3

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.

Affinity objects AWS S3 objects
List Entries The membership of a person, organization, or opportunity on a list, carrying its list-specific fields. Object Metadata System and user-defined metadata read alongside object contents.
Persons Contact records enriched with relationship intelligence, synced with CRMs and outreach tools. Object Versions Prior copies retained when versioning is enabled, relevant for reprocessing.
Organizations Company records matched to accounts in other systems by domain. Event Notifications Notifications on object creation or deletion that trigger incremental processing.
Opportunities Deal records tracked on lists and synced with pipeline reporting. Access Points Scoped network endpoints used to grant a sync narrow access to a bucket.
Field Values Custom field data, either global or scoped to a list, mapped field-by-field in syncs. Multipart Uploads The mechanism used to write large export files reliably.
Notes Meeting and call notes synced for record-keeping in other systems. Buckets Top-level containers a sync targets; region and policy are set at this level.
