Why teams connect Apollo.io and Pinecone

Write what Pinecone computes onto the contacts, accounts, and deals in Apollo.io, and feed Apollo.io's records back into Pinecone, in real time and in both directions.

Pinecone turns data into something a revenue team can act on: scores, classifications, summaries, and embeddings. But the customers those results describe live in Apollo.io, where reps and marketers actually work. Intelligence that stays inside Pinecone rarely reaches the record where a decision gets made, and Pinecone is only as sharp as the data it sees, which is also held in Apollo.io.

Stacksync connects Vectors (records), Namespaces, Collections, Backups in Pinecone to Deals (Opportunities), Tasks and calls, Custom fields, Contacts in Apollo.io with bi-directional, real-time sync. Records and fields from Apollo.io flow into Pinecone as the material it scores, indexes, or enriches, and the values Pinecone produces flow back onto the matching contact, account, or deal in Apollo.io, field by field, within seconds. There is no batch export in the middle and no glue code to maintain.

Because the mapping is field-level, you choose exactly which attributes cross and in which direction, so Apollo.io stays the record of the customer while Pinecone stays where the computation happens.

Common use cases

  • 01 Read an index's vectors and per-namespace statistics into a warehouse for auditing what is stored, sizing cost, and detecting drift from the source data.
  • 02 Migrate or clone vectors between Pinecone indexes, projects, or namespaces - or from another vector store into Pinecone - using batched upserts.
  • 03 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
  • 04 Deduplicate contacts across Apollo and the CRM by syncing on email as the match key.

Common sync patterns

Where Pinecone classifies or tags: labels sync onto the record

Categories, sentiment, or intent produced in Pinecone attach to the right contact, account, or deal in Apollo.io, keeping segmentation current as new data arrives.

Where Pinecone indexes records for retrieval: Apollo.io keeps it fresh

Contacts, accounts, and notes from Apollo.io sync into Pinecone as they change, so embeddings or search stay aligned with the live CRM instead of a stale export.

Where Pinecone summarizes or drafts: text where reps read it

Summaries, next steps, or drafted messages generated in Pinecone write back onto the account or deal in Apollo.io, next to the relationship they describe.

What you can sync between Apollo.io and Pinecone

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.

Apollo.io objects Pinecone objects How this pairing syncs
Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. Index statistics Describe_index_stats returns total and per-namespace vector counts, the index dimension, and index fullness; read to size a sync and to detect drift between Pinecone and the source of truth. Custom fields is specific to Apollo.io and Index statistics to Pinecone — each maps to any object or custom field on the other side.
Contacts People saved to your Apollo account, synced with emails, phone numbers, and enrichment fields. Indexes Serverless or pod-based containers holding vectors of a fixed dimension and distance metric (cosine, dotproduct, euclidean); managed on the control plane (api.pinecone.io) via create, list, describe, configure, and delete. describe_index returns the per-index data-plane host. Contacts is specific to Apollo.io and Indexes to Pinecone — each maps to any object or custom field on the other side.
Accounts Company records with firmographic attributes, matched to CRM accounts during sync. Vectors (records) The core data: an id (up to 512 chars), a dense values array, optional sparse_values, and JSON metadata (up to 40 KB filterable per record). Full CRUD on the data plane via upsert, update, fetch, query, and delete, so write is supported here. Accounts is specific to Apollo.io and Vectors (records) to Pinecone — each maps to any object or custom field on the other side.
People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. Namespaces Partitions inside an index; every read and write targets one namespace and vectors across namespaces are isolated. Enumerated with list_namespaces and sized per namespace via describe_index_stats. People (database records) is specific to Apollo.io and Namespaces to Pinecone — each maps to any object or custom field on the other side.
Sequences Outreach cadences (emailer campaigns in the API); enrollment status is read to track which contacts are being worked. Collections Immutable snapshots of a pod-based index that store its data but not its definition; created, listed, and deleted on the control plane and used to recreate a pod-based index. Serverless indexes use Backups instead. Sequences is specific to Apollo.io and Collections to Pinecone — each maps to any object or custom field on the other side.
Deals (Opportunities) Pipeline records that can be read and written to keep Apollo aligned with the CRM of record. Backups Point-in-time snapshots of a serverless index; created, listed, and restored into a new index on the control plane for recovery or cloning. Read as a recovery-asset inventory. Deals (Opportunities) is specific to Apollo.io and Backups to Pinecone — each maps to any object or custom field on the other side.

How changes propagate between Apollo.io and Pinecone

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 Pinecone 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.

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

Pinecone Apollo.io Interval-based propagation

DetectionStacksync polls Pinecone for changes on an incremental schedule, reading only records changed since the previous pass. No webhooks and no native change-data-capture feed.

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.
  • Pinecone: Data-plane operations are capped per second: query, upsert, update, and delete at 100 req/s per namespace, fetch at 100 req/s per index, and list at 200 req/s per index; breaches return HTTP 429. Hard request limits also apply: an upsert is max 2 MB or 1000 records, metadata max 40 KB per record, and query top_k up to 10,000 with a 4 MB result cap.

Pinecone

Integration surface
Two HTTP APIs: a control plane at api.pinecone.io (manage indexes, collections, backups, and, via the Admin API, projects and API keys) and a per-index data plane at the host returned by describe_index (upsert, query, fetch, update, delete, list). A gRPC data-plane transport is available through the official SDKs.
Authentication
API key in the Api-Key request header, scoped to one project; every request also sends an X-Pinecone-Api-Version header (date-based, e.g. 2025-10). The organization Admin API instead uses OAuth2 client-credentials (service accounts) via login.pinecone.io/oauth/token, passing a Bearer token to api.pinecone.io/admin (Enterprise).
Change detection
No webhooks and no native change-data-capture feed. Vectors carry no server-side update timestamp, so Stacksync detects changes by re-reading - paginating vector ids with the list operation (serverless indexes) and fetching by id, or by re-upserting from the source of truth. describe_index_stats bounds a resync with per-namespace counts.
