Why teams connect Customer.io and PagerDuty

Connect the tickets, records, and events in Customer.io to the systems engineering runs in PagerDuty, kept current in real time and in both directions.

Customer.io is where customer-facing and operational work happens: the tickets, conversations, contacts, and records a team touches every day. PagerDuty is where engineering runs the systems behind that work — the issue trackers, message brokers, directories, and monitors that keep services moving. The same items, people, and events matter to both, and when the only link between them is a manual hand-off or an overnight export, each side acts on a stale copy of what the other already knows.

Stacksync syncs Deliveries / Messages, Newsletters, People, Objects in Customer.io with Teams, Schedules, Escalation Policies, On-Calls in PagerDuty field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync maps the overlap, resolves conflicts by rules you set, and keeps every copy current, with no middleware to build and no API limits to babysit.

Common use cases

  • 01 Land delivery and engagement events (sent, opened, clicked, bounced) from reporting webhooks into a warehouse for attribution analysis.
  • 02 Keep unsubscribe and subscription-preference state consistent between Customer.io and the CRM to avoid compliance gaps.
  • 03 Write Schedules and Escalation Policies from a workforce tool or source-of-truth spreadsheet so rotations and overrides stay consistent across teams.
  • 04 Mirror Services and their integration keys with a CMDB or service catalog so ownership and tier metadata stay aligned in both directions.

Common sync patterns

Where PagerDuty tracks engineering work: requests become issues

A ticket or request raised in Customer.io opens or updates a matching issue in PagerDuty, and status, comments, and resolution flow back, so support and engineering work the same item instead of retyping it.

Where PagerDuty moves messages between services: activity lands on the stream

Records created or changed in Customer.io publish to the queue or topic in PagerDuty as they happen, so downstream services react to real events rather than polling for them.

Where PagerDuty is the directory or identity source: one set of users

People and accounts in Customer.io stay matched to the users in PagerDuty, so access, provisioning, and org changes propagate instead of being keyed in twice.

What you can sync between Customer.io and PagerDuty

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.

Customer.io objects PagerDuty objects How this pairing syncs
Campaigns Automated workflows whose membership and metrics can be read via the App API. Users Responders with contact methods and notification rules; provisioned and updated two-way to keep the on-call roster aligned with an HRIS or identity provider. Campaigns is specific to Customer.io and Users to PagerDuty — each maps to any object or custom field on the other side.
Broadcasts One-off sends to segments or audiences, triggerable via API. Teams Groupings of users, services, and escalation policies; synced two-way so membership mirrors org structure from an IdP or HRIS. Broadcasts is specific to Customer.io and Teams to PagerDuty — each maps to any object or custom field on the other side.
Deliveries / Messages Per-recipient message records whose lifecycle events flow out through reporting webhooks. Schedules On-call rotations built from layers and overrides; read and written so calendar or workforce tools can drive who is on call. Deliveries / Messages is specific to Customer.io and Schedules to PagerDuty — each maps to any object or custom field on the other side.
Newsletters Recurring email sends with performance metrics available for reporting syncs. Escalation Policies Ordered rules routing incidents to users and schedules; read and written two-way to codify paging logic from a source of truth. Newsletters is specific to Customer.io and Escalation Policies to PagerDuty — each maps to any object or custom field on the other side.
People Profiles with attributes, matched on identifiers like id or email; the main write target of data syncs. On-Calls Computed view of who is on call now, derived from schedules and escalation policies; read-only, ideal for pushing current responders into other systems. People is specific to Customer.io and On-Calls to PagerDuty — each maps to any object or custom field on the other side.
Objects Non-person entities such as accounts or companies, related to people for account-level messaging. Notes and Log Entries Notes are writable to append context to an incident; log entries are a read-only record of every action taken on that incident. Objects is specific to Customer.io and Notes and Log Entries to PagerDuty — each maps to any object or custom field on the other side.

How changes propagate between Customer.io and PagerDuty

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.

Customer.io PagerDuty Sub-second propagation

DetectionCustomer.io notifies Stacksync of record changes through webhook events. Reporting webhooks push message and delivery events.

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

PagerDuty Customer.io Sub-second propagation

DetectionPagerDuty notifies Stacksync of record changes through webhook events. V3 webhook subscriptions push incident.* and service.* events (triggered, acknowledged, escalated, resolved, created, updated).

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

Rate-limit considerations

  • Customer.io: Subject to per-API rate limits documented by Customer.io.
  • PagerDuty: REST API allows 960 requests per minute per token and returns HTTP 429 when exceeded; the Events API is rate-limited separately per integration key.

How the Customer.io and PagerDuty connectors work

Customer.io

Integration surface
REST APIs split by purpose: Track API for data ingestion, App API for campaigns, people lookups, and messages
Authentication
Basic auth with site ID and API key for the Track API; bearer token for the App API
Change detection
Reporting webhooks push message and delivery events; person attribute changes are not streamed and require source-side detection
Capabilities
read · write · webhooks
Rate limits
Subject to per-API rate limits documented by Customer.io

PagerDuty

Integration surface
REST API v2 (plus Events API v2 for inbound alerts)
Authentication
REST API token via the Authorization: Token header (account-level for full access or user-level scoped to the user's permissions), or OAuth 2.0 (Authorization Code / PKCE); the Events API v2 uses a per-service routing (integration) key
Change detection
V3 webhook subscriptions push incident.* and service.* events (triggered, acknowledged, escalated, resolved, created, updated); list endpoints also support polling with updated_at and since/until windows
Capabilities
read · write · webhooks
Rate limits
REST API allows 960 requests per minute per token and returns HTTP 429 when exceeded; the Events API is rate-limited separately per integration key.
