We recently introduced the WhatsApp Embedded Signup flow in Chatwoot to
simplify onboarding. However, we discovered two important limitations:
Some customers’ numbers are already linked to an Embedded Signup, which
blocks re-use. Tech providers cannot onboard their own numbers via
Embedded Signup.
As a result, we need to support both Manual and Embedded Signup flows to
cover all scenarios.
### Problem
- Current UI only offers the Embedded Signup option.
- Customers who need to reuse existing numbers (already connected to
WABA) or tech providers testing their own numbers get stuck.
- Manual flow exists but is no longer exposed in the UX
**Current Embedded Signup screen**

/>
### Solution
- Design a dual-path UX in the Create WhatsApp Inbox step that:
- Offers Embedded Signup (default/recommended) for new numbers and
businesses.
- Offers Manual Setup for advanced users, existing linked numbers, and
tech providers.

I've added the account_id filter to the
`get_agent_ids_over_assignment_limit` method. This optimization will
help the query leverage the existing composite index
`conv_acid_inbid_stat_asgnid_idx (account_id, inbox_id, status,
assignee_id)` for better performance.
**Before:**
```sql
HashAggregate (cost=224238.12..224256.27 rows=484 width=4)
Group Key: assignee_id
Filter: (count(*) >= 10)
-> Index Scan using index_conversations_on_inbox_id on conversations (cost=0.44..223963.67 rows=54891 width=4)
Index Cond: (inbox_id = ???)
Filter: (status = 0)
```
**After:**
```sql
GroupAggregate (cost=0.44..5688.30 rows=476 width=4)
Group Key: assignee_id
Filter: (count(*) >= 10)
-> Index Only Scan using conv_acid_inbid_stat_asgnid_idx on conversations (cost=0.44..5640.81 rows=5928 width=4)
Index Cond: ((account_id = ??) AND (inbox_id = ??) AND (status = 0))
```
Deleting large Accounts/Inboxes with object.destroy! can time out and
create heavy destroy_async fan-out; this change adds a simple pre-purge
that batch-destroys heavy associations first .
```
Account: conversations, contacts
Inbox: conversations, contact_inboxes
```
We use find_in_batches(5000), then proceeds with destroy!, reducing DB
pressure and race conditions while preserving callbacks and leaving the
behavior for non heavy models unchanged. The change is also done in a
way to easily add additional objects or relations to the list.
fixes:
https://linear.app/chatwoot/issue/CW-3106/inbox-deletion-process-update-the-flow
The system determines a user’s active account by checking the
`active_at` field in the `account_users` table and selecting the most
recently active account:
```ruby
def active_account_user
account_users.order(active_at: :desc)&.first
end
```
This works fine when all accounts have a valid active_at timestamp.
**Problem**
When a user is added to a new account, the `active_at` value is NULL
(because the account has never been explicitly activated). Ordering by
active_at DESC produces inconsistent results across databases, since
handling of NULL values differs (sometimes treated as high, sometimes
low).
As a result:
- Mobile apps (critical impact): `/profile` returns the wrong account.
The UI keeps showing the old account even after switching, and
restarting does not fix it.
- Web app (accidentally works): Appears correct because the active
account is inferred from the browser URL, but the backend API is still
wrong.
**Root Cause**
- The ordering logic did not account for NULL `active_at`.
- New accounts without active_at sometimes get incorrectly prioritized
as the “active” account.
**Solution**
Explicitly ensure that accounts with NULL active_at are sorted after
accounts with real timestamps by using NULLS LAST:
```ruby
def active_account_user
account_users.order(Arel.sql('active_at DESC NULLS LAST, id DESC'))&.first
end
```
- Accounts with actual `active_at` values will always be prioritized.
- New accounts (with NULL active_at) will be placed at the bottom until
the user explicitly activates them.
- Adding id DESC as a secondary ordering ensures consistent tie-breaking
when multiple accounts have the same `active_at`.

This PR delivers the first slice of the voice channel: inbound call
handling. When a customer calls a configured voice
number, Chatwoot now creates a new conversation and shows a dedicated
call bubble in the UI. As the call progresses
(ringing, answered, completed), its status updates in real time in both
the conversation list and the call bubble, so
agents can instantly see what’s happening. This focuses on the inbound
flow and is part of breaking the larger voice
feature into smaller, functional, and testable units; further
enhancements will follow in subsequent PRs.
references: #11602 , #11481
## Testing
- Configure a Voice inbox in Chatwoot with your Twilio number.
- Place a call to that number.
- Verify a new conversation appears in the Voice inbox for the call.
- Open it and confirm a dedicated voice call message bubble is shown.
- Watch status update live (ringing/answered); hang up and see it change
to completed in both the bubble and conversation
list.
- to test missed call status, make sure to hangup the call before the
please wait while we connect you to an agent message plays

This PR adds the foundation for account-level SAML SSO configuration in
Chatwoot Enterprise. It introduces a new `AccountSamlSettings` model and
management API that allows accounts to configure their own SAML identity
providers independently, this also includes the certificate generation
flow
The implementation includes a new controller
(`Api::V1::Accounts::SamlSettingsController`) that provides CRUD
operations for SAML configuration
The feature is properly gated behind the 'saml' feature flag and
includes administrator-only authorization via Pundit policies.
There was a fundamental difference in how resolution counts were
calculated between the agent summary and timeseries reports, causing
confusion for users when the numbers didn't match.
The agent summary report counted all `conversation_resolved` events
within a time period by querying the `reporting_events` table directly.
However, the timeseries report had an additional constraint that
required the conversation to currently be in resolved status
(`conversations.status = 1`). This meant that if an agent resolved a
conversation that was later reopened, the resolution action would be
counted in the summary but not in the timeseries.
This fix aligns both reports to count resolution events rather than
conversations in resolved state. When an agent resolves a conversation,
they should receive credit for that action regardless of what happens to
the conversation afterward. The same logic now applies to bot
resolutions as well.
The change removes the `conversations: { status: :resolved }` condition
from both `scope_for_resolutions_count` and
`scope_for_bot_resolutions_count` methods in CountReportBuilder, and
updates the corresponding test expectations to reflect that all
resolution events are counted.
## About timezone
When a timezone is specified via `timezone_offset` parameter, the
reporting system:
1. Converts timestamps to the target timezone before grouping
2. Groups data by local day/week/month boundaries in that timezone, but
the primary boundaries are sent by the frontend and used as-is
3. Returns timestamps representing midnight in the target timezone
This means the same events can appear in different day buckets depending
on the timezone used. For summary reports, it works fine, since the user
only needs the total count between two timestamps and the frontend sends
the timestamps adjusted for timezone.
## Testing Locally
Run the following command, this will erase all data for that account and
put in 1000 conversations over last 3 months, parameters of this can be
tweaked in `Seeders::Reports::ReportDataSeeder`
I'd suggest updating the values to generate data over 30 days, with
10000 conversations, it will take it's sweet time to run but then the
data will be really rich, great for testing.
```
ACCOUNT_ID=2 ENABLE_ACCOUNT_SEEDING=true bundle exec rake db:seed:reports_data
```
Pro Tip: Don't run the app when the seeder is active, we manually create
the reporting events anyway. So once done just use `redis-cli FLUSHALL`
to clear all sidekiq jobs. Will be easier on the system
Use the following scripts to test it

Currently, auto-assignment runs only during conversation creation or
update events. If no agents are online when new conversations arrive,
those conversations remain unassigned.
With this change, unassigned conversations will be automatically
assigned once agents become available. The job runs every 15 minutes and
uses a fair distribution threshold of 100 to prevent a large number of
conversations from being assigned to a single available agent. This will
be customizable later.

We now support searching within the actual message content, email
subject lines, and audio transcriptions. This enables a faster, more
accurate search experience going forward. Unlike the standard message
search, which is limited to the last 3 months, this search has no time
restrictions.
The search engine also accounts for small variations in queries. Minor
spelling mistakes, such as searching for slck instead of Slack, will
still return the correct results. It also ignores differences in accents
and diacritics, so searching for Deja vu will match content containing
Déjà vu.
We can also refine searches in the future by criteria such as:
- Searching within a specific inbox
- Filtering by sender or recipient
- Limiting to messages sent by an agent

There were customer reported issues with FAQs which were generated in a
different langauge than what they were expecting. The reason behind this
was that the language of the account was not considered in the prompt
provided. If the language of the content was say Spanish, and the
account locale was english. The output was not predicable. The output
depends on the model and the execution time.
This PR would update the prompt to behave consistently with the account
locale. Even though the content provided is in a different language, it
would generate FAQs in the account locale.
Changes:
- Updated the prompt to include a detailed expectation of the FAQs
quality along with the language
- Added specs for the services where the prompt generator is called.
Tested the prompt using Phoenix playground across GPT 5, GPT 4.1, GPT
4.0. The reasoning setting for GPT 5 needs to be low so that it doesn't
generate random questions like "What was this updated?"
This PR improves the voice call creation flow by simplifying
configuration and automating setup with Twilio APIs.
references: #11602 , #11481
## Key changes
- Removed the requirement for twiml_app_sid – provisioning is now
automated through APIs.
- Auto-configured webhook URLs for:
- Voice number callbacks
- Status callbacks
- twiML callbacks
- Disabled business hours, help center, and related options until voice
inbox is fully supported.
- Added a configuration tab in the voice inbox to display the required
Twilio URLs (to make verification easier in Twilio console).
## Test Cases
- Provisioning
- Create a new voice inbox → verify that Twilio app provisioning happens
automatically.
- Verify twiML callback
- Webhook configuration
- Check that both voice number callback and status callback URLs are
auto-populated in Twilio.
- Disabled features
- Confirm that business hours and help center options are
hidden/disabled for voice inbox.
- Configuration tab
- Open the voice inbox configuration tab → verify that the displayed
Twilio URLs match what’s set in Twilio.

# Pull Request Template
## Description
Fixes
https://linear.app/chatwoot/issue/CW-5411/actionviewtemplateerror-activestorageunrepresentableerror
### Problem
API endpoints return 500 errors when conversations contain image
attachments that can't be processed by ActiveStorage (e.g., files with
non-ASCII filenames, corrupted images, or malicious XSS filenames).
Root Cause: Commit 6cab74139 removed the representable? safety check
from thumb_url, causing `ActiveStorage::UnrepresentableError` to bubble
up and crash the API when it encountered a malformed image file.
Fix: Rescue `thumb_url` method to catch UnrepresentableError and return
an empty string while logging problematic names for future debugging.
This ensures the messages/attachments api does not break due to a single
corrupted image file.

WhatsApp templates without parameters (body-only templates like
notifications, confirmations) were failing to send with the error:
ArgumentError (Unknown legacy format: NilClass). This affected all
parameter-less templates across marketing messages, notifications, and
utility templates.
### Summary
Fixed flaky Instagram webhook specs that failed intermittently in cloud
environments due to shared let blocks creating conflicting inboxes. The
Instagram channel factory already creates an inbox automatically, but
tests were adding extra ones in shared contexts.
Moved channel/inbox creation to isolated test contexts to prevent race
conditions between Facebook Page and Instagram Direct tests.
### Testing
```
for i in {1..30}; do
echo "=== Run $i ==="
RAILS_ENV=test bundle exec rspec spec/jobs/webhooks/instagram_events_job_spec.rb --fail-fast || break
done
```
Previously, intermittent failures could be reproduced locally. With
these changes, tests achieve ~100% pass rate.
WhatsApp template message errors were not being properly handled because
the `@message instance` variable was only set in the `send_message`
method but not in `send_template`. When template sending failed, the
`handle_error` method couldn't update the message status due to the
missing @message reference, resulting in silent failures with no user
feedback.
This PR fixes flaky test failures in the Instagram webhook specs that
were caused by Redis mutex lock conflicts when
tests ran in parallel.
### The Problem:
The InstagramEventsJob uses a Redis mutex with a key based on sender_id
and ig_account_id to prevent race
conditions. However, all test factories were using the same hardcoded
sender_id: 'Sender-id-1', causing multiple
test instances to compete for the same mutex lock when running in
parallel.
### The Solution:
- Updated all Instagram event factories to generate unique sender IDs
using SecureRandom.hex(4)
- Modified test stubs and expectations to work with dynamic sender IDs
instead of hardcoded values
- Ensured each test instance gets its own unique mutex key, eliminating
lock contention
## Summary
- handle Twilio failures per contact when running one-off SMS campaigns
- rescue errors in WhatsApp and generic SMS one-off campaigns so they
continue
- add specs confirming campaigns continue sending when a single contact
fails

This update adds support to the coexistence method to Embedded Whatsapp,
allowing users to add their existing whatsapp business number in order
to use it in both places(chatwoot and whatsapp business) at the same
time.
This update require some changes in the permissions for the Meta App, as
described in the Meta Oficial Docs, I'll leave this listed below:
- **history** — describes past messages the business customer has
sent/received
- **smb_app_state_sync** — describes the business customer's current and
new contacts
- **smb_message_echoes** — describes any new messages the business
customer sends with the WhatsApp Business app after having been
onboarded

Database CPU utilization was spiking due to expensive notification COUNT
queries. Analysis revealed two critical issues:
1. Missing database index: Notification count queries were performing
table scans without proper indexing
2. Duplicate WHERE clauses: SQL queries contained redundant read_at IS
NULL conditions, causing unnecessary query complexity
### Root Cause Analysis
The expensive queries were:
```
-- 41.61 calls/sec with duplicate condition
SELECT COUNT(*) FROM "notifications"
WHERE "notifications"."user_id" = $1
AND "notifications"."account_id" = $2
AND "notifications"."snoozed_until" IS NULL
AND "notifications"."read_at" IS NULL
AND "notifications"."read_at" IS NULL -- Duplicate!
```
This was caused by a logic error in NotificationFinder#unread_count
introduced in commit cd06b2b33 (PR #8907). The method assumed
@notifications contained all notifications, but @notifications was
already filtered to unread notifications in most cases.
### The Default Query Flow:
1. Frontend calls: NotificationsAPI.getUnreadCount() →
/notifications/unread_count
2. No parameters sent, so params = {}
3. NotificationFinder setup:
- find_all_notifications: WHERE user_id = ? AND account_id = ?
- filter_snoozed_notifications: WHERE snoozed_until IS NULL
- filter_read_notifications: WHERE read_at IS NULL (because
type_included?('read') is false)

2. Fixed Duplicate WHERE Clause Logic
