This pull request fixes push notification linking and payload consistency across chat, call, and Apple/iOS notification flows.

What changed

  • Fixed direct chat push linking

    • Corrected the ID used when sending a chat notification to a single recipient so it uses the recipient’s UserId.
    • This ensures chat push notifications link to the intended user correctly.
  • Fixed call push notification title/subtitle ordering

    • Updated legacy Azure push notifications for calls to send the title and subtitle in the correct order.
    • This aligns the notification content shown to users with the intended call message format.
  • Updated Apple/iOS push payloads to include custom data in a body field

    • Added a top-level body object containing eventCode and type in APNS payloads.
    • Applied this change in the bus notification provider, unit notification provider, and Novu provider.
  • Preserved backward compatibility for existing apps

    • Existing top-level and older payload fields remain in place while adding the new body structure.
    • This supports newer iOS/Expo notification handling without removing data relied on by already deployed clients.

Functional impact

These changes improve notification deep-linking and data delivery, especially for iOS/Expo-based apps, so notifications carry the expected metadata needed to open the correct screen or action when tapped.

Review Change Stack

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your current included review allowance is based on your included PR review attempts over the past 7 days.

Next review available in: 1 minute

Limit details: You’ve used all 2 included reviews currently available. Your 57 included PR review attempts over the past 7 days set your current allowance at 2 reviews per hour.

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The change corrects chat notification IDs and call title ordering. It adds nested body data with eventCode and type to APNs payloads across bus and Novu providers while preserving existing fields.

Changes

Notification payload corrections

Layer / File(s) Summary
Notification routing corrections
Core/Resgrid.Services/CommunicationService.cs, Core/Resgrid.Services/PushService.cs
Chat notifications now use UserId values. Call notifications now pass the title before the subtitle.
APNs custom payload contract
Providers/Resgrid.Providers.Bus/Models/APNSPayload.cs, Providers/Resgrid.Providers.Bus/NotificationProvider.cs, Providers/Resgrid.Providers.Bus/UnitNotificationProvider.cs
The APNs model and bus providers now support nested body data containing eventCode and type.
Novu APNs payload construction
Providers/Resgrid.Providers.Messaging/NovuProvider.cs
Novu APNs payload variants now include nested body, eventCode, and type data while retaining existing compatibility fields.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to ef619

A single-recipient chat can fail to send when the recipient lookup returns no result because the code accesses the recipient before checking for null. The PR is otherwise mergeable with explicit owner awareness and follow-up on this bounded delivery issue.

kody code-review Bug high

NullReferenceException risk in Core/Resgrid.Services/CommunicationService.cs: the single-recipient chat path dereferences sendingTo.UserId before the null check, and a missing profile from GetProfileByUserIdAsync can produce recipients.FirstOrDefault() == null from a one-item [null] recipients list. Move the sendingTo null guard before assigning spm.Id and before calling CanSendToUser so SendChat can return false instead of throwing.

var sendingTo = recipients.FirstOrDefault();
if (sendingTo == null)
	return false;

spm.Id = $"T{sendingTo.UserId}";

if (!await CanSendToUser(sendingTo.UserId, departmentId))
	return false;

Use one shared APNs payload contract.

This file adds ApnsPayload and ApnsCustomData, but the supplied graph also shows same-named types in Providers/Resgrid.Providers.Bus/NotificationProvider.cs, Providers/Resgrid.Providers.Bus/UnitNotificationProvider.cs, and Providers/Resgrid.Providers.Messaging/NovuProvider.cs. Those providers resolve their namespace-local types, so this model does not govern the changed payloads. Move the shared types to a common model assembly, or remove the duplicates and reference one explicit contract. Otherwise the body structure can drift.
