Why teams connect PagerDuty and Resend

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

Resend 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 Email events, API keys, Emails, Contacts in Resend with Services, Users, Teams, Schedules 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 Sync CRM contact segments into Resend Audiences so lifecycle broadcasts target current data.
  • 02 Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • 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 is the directory or identity source: one set of users

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

Where PagerDuty watches operations: live volumes for visibility

Open items, throughput, and error counts from Resend replicate into PagerDuty, so the operational view reflects what is actually happening in the business.

One shared record across both systems

Where both systems keep records for the same contacts, items, or users, a correction in either updates the other, ending dual maintenance and keeping IDs aligned for every other flow.

What you can sync between PagerDuty and Resend

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.

PagerDuty objects Resend objects How this pairing syncs
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. Domains Verified sending domains with DNS and DKIM status. Users is specific to PagerDuty and Domains to Resend — each maps to any object or custom field on the other side.
Teams Groupings of users, services, and escalation policies; synced two-way so membership mirrors org structure from an IdP or HRIS. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems. Teams is specific to PagerDuty and Email events to Resend — each maps to any object or custom field on the other side.
Schedules On-call rotations built from layers and overrides; read and written so calendar or workforce tools can drive who is on call. API keys Scoped credentials managed per environment for send and read access. Schedules is specific to PagerDuty and API keys to Resend — each maps to any object or custom field on the other side.
Escalation Policies Ordered rules routing incidents to users and schedules; read and written two-way to codify paging logic from a source of truth. Emails Sent messages retrievable by ID with current delivery status. Escalation Policies is specific to PagerDuty and Emails to Resend — each maps to any object or custom field on the other side.
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. Contacts Recipient records with email, name, and subscription state, synced from CRMs or databases. On-Calls is specific to PagerDuty and Contacts to Resend — each maps to any object or custom field on the other side.
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. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments. Notes and Log Entries is specific to PagerDuty and Audiences to Resend — each maps to any object or custom field on the other side.

How changes propagate between PagerDuty and Resend

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.

PagerDuty Resend 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 Resend through its API, with automatic retries and rate-limit backoff.

Resend PagerDuty Sub-second propagation

DetectionResend notifies Stacksync of record changes through webhook events. Webhooks for email lifecycle events.

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

Rate-limit considerations

  • 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.

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
