Why teams connect Apollo.io and GitHub
Sync what happens in GitHub with the customer records in Apollo.io, in real time and in both directions.
The CRM is supposed to be the record of every customer relationship, but customer-relevant information also accumulates in the other tools a team runs. Whatever GitHub holds or produces that touches a customer, whether conversations, payments, replies, enriched data, or notes, the CRM only benefits if it arrives without someone copying it over.
Stacksync connects Users, Labels and Milestones, Repositories, Issues in GitHub to Accounts, People (database records), Sequences, Deals (Opportunities) in Apollo.io with bi-directional, real-time sync. Activity and record changes in GitHub update the matching contact or account in Apollo.io, and CRM data flows the other way wherever GitHub can store and use it.
Common use cases
- 01 Two-way sync of GitHub issues with Jira, Linear, or a support system so engineering and customer-facing teams work in their own tools.
- 02 Mirror repository, PR, and workflow-run data into a Postgres database for engineering-metrics reporting.
- 03 Push CRM opportunity stages back into Apollo so reps see pipeline context while sequencing.
- 04 Land sequence enrollment status and outcomes in a warehouse for outbound performance reporting.
Common sync patterns
Where GitHub handles support or shared inboxes
Tickets and conversations attach to the right contact and account in Apollo.io, so sales sees open issues before the next call.
Where GitHub supplies contact or company data
Enriched fields land directly on records in Apollo.io, and refreshes keep them from going stale.
Where GitHub can store CRM context: fields kept current
Owner, lifecycle stage, or account details from Apollo.io sync into GitHub, so people working there have the context without switching tools.
What you can sync between Apollo.io and GitHub
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 | GitHub objects | How this pairing syncs | |
|---|---|---|---|
| People (database records) Prospects from Apollo's global database, pulled into downstream systems once enriched or saved. | Organizations and Teams Membership data synced with identity systems and HR directories for access reviews. | People (database records) is specific to Apollo.io and Organizations and Teams to GitHub — 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. | Users Author and assignee identities matched to internal directories. | Sequences is specific to Apollo.io and Users to GitHub — 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. | Labels and Milestones Classification fields mapped to statuses and sprints in external trackers. | Deals (Opportunities) is specific to Apollo.io and Labels and Milestones to GitHub — each maps to any object or custom field on the other side. | |
| Tasks and calls Rep activity records synced for activity reporting and coaching workflows. | Repositories Top-level containers whose metadata and settings syncs read to scope other objects. | Tasks and calls is specific to Apollo.io and Repositories to GitHub — each maps to any object or custom field on the other side. | |
| Custom fields Account- and contact-level custom attributes mapped field-by-field in a sync. | Issues Synced two-way with project trackers and support tools, including labels and assignees. | Custom fields is specific to Apollo.io and Issues to GitHub — 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. | Pull Requests Review state, status checks, and merge status feed engineering dashboards and workflow tools. | Contacts is specific to Apollo.io and Pull Requests to GitHub — each maps to any object or custom field on the other side. |
How changes propagate between Apollo.io and GitHub
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 GitHub 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 GitHub through its API, with automatic retries and rate-limit backoff.
GitHub Apollo.io Sub-second propagation
DetectionGitHub notifies Stacksync of record changes through webhook events. Webhooks with a broad event catalog covering issues, pull requests, pushes, and releases.
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.
- GitHub: Authenticated REST requests are limited to 5,000 per hour per user; GitHub Apps scale limits per installation.

FAQ
Apollo.io and GitHub integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Apollo.io and GitHub: authenticate both systems, choose the objects to sync (such as Apollo.io's People (database records) and Sequences), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
GitHub: Webhook deliveries are signed with a shared secret (HMAC), letting receivers verify payload authenticity before applying changes. Apollo.io: Apollo distinguishes between people in its global database and contacts saved to your account; only saved contacts carry your custom fields and sequence history. Stacksync's field mapping accounts for these differences between Apollo.io and GitHub without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Apollo.io and GitHub records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Apollo.io and GitHub connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Apollo.io–GitHub integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Apollo.io and GitHub. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Apollo.io: Polling on updated-at timestamps; webhook callbacks exist only for delivering asynchronous enrichment results, not as a general change-event stream. On GitHub: Webhooks with a broad event catalog covering issues, pull requests, pushes, and releases; polling for backfill. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
