Previously, attachments relied only on blob_id, which made it possible
to attach blobs across accounts by enumerating IDs. We now require both
blob_id and blob_key, add cross-account validation to prevent blob
reuse, and centralize the logic in a shared BlobOwnershipValidation
concern.
It also fixes a frontend bug where mixed-type action params (number +
string) were incorrectly dropped, causing attachment uploads to fail.
Text in hebrew was broken and incomplete - i have completed the
translation and fixed some annoying terms for better understanding and
user experience.
Description
This pull request updates several Lithuanian (lt.json) translations in
the Chatwoot widget.
The previous versions contained grammatical issues, unnatural phrasing,
and direct machine-translated structures.
The updated translations now follow proper Lithuanian grammar, natural
wording, and are consistent with the tone used across the rest of the
UI.
Fixes: No linked issue (translation improvement).
fixes: #11834
This pull request introduces TikTok channel integration, enabling users
to connect and manage TikTok business accounts similarly to other
supported social channels. The changes span backend API endpoints,
authentication helpers, webhook handling, configuration, and frontend
components to support TikTok as a first-class channel.
**Key Notes**
* This integration is only compatible with TikTok Business Accounts
* Special permissions are required to access the TikTok [Business
Messaging
API](https://business-api.tiktok.com/portal/docs?id=1832183871604753).
* The Business Messaging API is region-restricted and is currently
unavailable to users in the EU.
* Only TEXT, IMAGE, and POST_SHARE messages are currently supported due
to limitations in the TikTok Business Messaging API
* A message will be successfully sent only if it contains text alone or
one image attachment. Messages with multiple attachments or those
combining text and attachments will fail and receive a descriptive error
status.
* Messages sent directly from the TikTok App will be synced into the
system
* Initiating a new conversation from the system is not permitted due to
limitations from the TikTok Business Messaging API.
**Backend: TikTok Channel Integration**
* Added `Api::V1::Accounts::Tiktok::AuthorizationsController` to handle
TikTok OAuth authorization initiation, returning the TikTok
authorization URL.
* Implemented `Tiktok::CallbacksController` to handle TikTok OAuth
callback, process authorization results, create or update channel/inbox,
and handle errors or denied scopes.
* Added `Webhooks::TiktokController` to receive and verify TikTok
webhook events, including signature verification and event dispatching.
* Created `Tiktok::IntegrationHelper` module for JWT-based token
generation and verification for secure TikTok OAuth state management.
**Configuration and Feature Flags**
* Added TikTok app credentials (`TIKTOK_APP_ID`, `TIKTOK_APP_SECRET`) to
allowed configs and app config, and registered TikTok as a feature in
the super admin features YAML.

requests.
* Updated channel icon mappings and tests to include TikTok
(`Channel::Tiktok`).

These changes collectively enable end-to-end TikTok channel support,
from configuration and OAuth flow to webhook processing and frontend
message handling.

# TikTok App Setup & Configuration
1. Grant access to the Business Messaging API
([Documentation](https://business-api.tiktok.com/portal/docs?id=1832184145137922))
2. Set the app authorization redirect URL to
`https://FRONTEND_URL/tiktok/callback`
3. Update the installation config with TikTok App ID and Secret
4. Create a Business Messaging Webhook configuration and set the
callback url to `https://FRONTEND_URL/webhooks/tiktok`
([Documentation](https://business-api.tiktok.com/portal/docs?id=1832190670631937))
. You can do this by calling
`Tiktok::AuthClient.update_webhook_callback` from rails console once you
finish Tiktok channel configuration in super admin ( will be automated
in future )
5. Enable TikTok channel feature in an account

### Problem
Currently, the attachment button visibility in the widget uses both the
SDK's `enableFileUpload` flag AND the inbox's attachment settings with
an AND condition. This creates an issue for users who want to control
attachments solely through inbox settings, since the SDK flag defaults
to `true` even when not explicitly provided.
**Before:**
- SDK not set → `enableFileUpload: true` (default) + inbox setting =
attachment shown only if both true
- SDK set to false → `enableFileUpload: false` + inbox setting =
attachment always hidden
- SDK set to true → `enableFileUpload: true` + inbox setting =
attachment shown only if both true
This meant users couldn't rely solely on inbox settings when the SDK
flag wasn't explicitly provided.
### Solution
Changed the logic to prioritize explicit SDK configuration when
provided, and fall back to inbox settings when not provided:
**After:**
- SDK not set → `enableFileUpload: undefined` → use inbox setting only
- SDK set to false → `enableFileUpload: false` → hide attachment (SDK
controls)
- SDK set to true → `enableFileUpload: true` → show attachment (SDK
controls)

`described_class.new`mocking with proper `GlobalConfigService` stubbing
and real JWT token generation. The old pattern doesn't work in request
specs since Rails instantiates controllers internally.
- User associations: Remove `.class_name('Conversation')` assertion that
fails intermittently due to enterprise `prepend_mod_with` timing in
parallel tests. The class_name is already enforced by Rails at runtime -
if wrong, the app would crash immediately. No need to explicitly test
for this

## Summary
Fixes the issue where double newlines (paragraph breaks) were collapsing
to single newlines in text-based messaging channels (Telegram, WhatsApp,
Instagram, Facebook, LINE, SMS).
### Root Cause
The `preserve_multiple_newlines` method only preserved 3+ consecutive
newlines using the regex `/\n{3,}/`. When users pressed Enter twice
(creating a paragraph break with 2 newlines), CommonMarker would parse
this as separate paragraphs, which then collapsed to a single newline in
the output.
This caused:
- ❌ Normal Enter: Double newlines collapsed to single newline
- ✅ Shift+Enter: Worked (created hard breaks)
### Fix
Changed the regex from `/\n{3,}/` to `/\n{2,}/` to preserve 2+
consecutive newlines. This prevents CommonMarker from collapsing
paragraph breaks.
Now:
- ✅ Single newline (`\n`) → Single newline (handled by softbreak)
- ✅ Double newline (`\n\n`) → Double newline (preserved with
placeholders)
- ✅ Triple+ newlines → Preserved as before
### Test Coverage
Added comprehensive tests for:
- Single newlines preservation
- Double newlines (paragraph breaks) preservation
- Multiple consecutive newlines
- Newlines with varying amounts of whitespace between them (1 space, 3
spaces, 5 spaces, tabs)
All 66 tests passing.
### Impact
This fix affects all text-based messaging channels that use the markdown
renderer:
- Telegram
- WhatsApp
- Instagram
- Facebook
- LINE
- SMS
- Twilio SMS (when configured for WhatsApp)

## Description
1. This PR is an enhancement to
https://github.com/chatwoot/chatwoot/pull/13045
It strips unsupported formatting from **message signatures** based on
each channel’s formatting capabilities defined in the `FORMATTING`
config
2. Remove usage of plain editor in Compose new conversation modal
Only the following signature elements are considered:
<strong>bold (<code inline="">strong</code>), italic (<code
inline="">em</code>), links (<code inline="">link</code>), images (<code
inline="">image</code>)</strong>.</p>
Any formatting not supported by the target channel is automatically
removed before the signature is appended.
<h3>Channel-wise Signature Formatting Support</h3>
Channel | Keeps in Signature | Strips from Signature
-- | -- | --
Email | bold, italic, links, images | —
WebWidget | bold, italic, links, images | —
API | bold, italic | links, images
WhatsApp | bold, italic | links, images
Telegram | bold, italic, links | images
Facebook | bold, italic | links, images
Instagram | bold, italic | links, images
Line | bold, italic | links, images
SMS | — | everything
Twilio SMS | — | everything
Twitter/X | — | everything
<hr>
<h3>📝 Note</h3>
<blockquote>
<p>Message signatures only support <strong>bold, italic, links, and
images</strong>.<br>
Other formatting options available in the editor (lists, code blocks,
strike-through, etc.) do <strong>not apply</strong> to signatures and
are ignored.</p>

## Description
Fixes an issue where multiple newlines with whitespace between them
(e.g., `\n \n \n`) were being collapsed to single newlines in text-based
messaging channels (Telegram, WhatsApp, Instagram, Facebook, Line, SMS).
The frontend was sending messages with spaces/tabs between newlines, and
the markdown renderer was treating these as paragraph content,
collapsing them during rendering.
### Changes:
1. Added whitespace normalization in `render_telegram_html`,
`render_whatsapp`, `render_instagram`, `render_line`, and
`render_plain_text` methods
2. Strips whitespace from whitespace-only lines before markdown
processing
3. Added comprehensive regression tests for all affected channels
## Type of change
- [x] Bug fix (non-breaking change which fixes an issue)
## How Has This Been Tested?
1. **Unit Tests**: Added 7 new specs testing multiple newlines with
whitespace between them for all text-based channels
2. **Manual Testing**: Verified with actual frontend payload containing
`\n \n \n` patterns
3. **Regression Testing**: All existing 63 specs pass
### Test Results:
- ✅ All 63 markdown renderer specs pass (56 original + 7 new)
- ✅ All 12 Telegram channel specs pass
- ✅ All 27 WhatsApp + Instagram specs pass
- ✅ Verified with real-world payload: 18 newlines preserved (previously
collapsed to 1)
### Test Command:
```bash
RAILS_ENV=test bundle exec rspec spec/services/messages/markdown_renderer_service_spec.rb
RAILS_ENV=test bundle exec rspec spec/models/channel/telegram_spec.rb
```

This PR fixes the HTTP 500 timeout errors occurring when deleting SLA
policies that have large volumes of historical data.
The fix moves the deletion workflow to asynchronous background
processing using the existing `DeleteObjectJob`.
By offloading heavy cascaded deletions (applied SLAs, SLA events,
conversation nullifications) from the request cycle, the API can now
return immediately while the cleanup continues in the background
avoiding the `Rack::Timeout::RequestTimeoutException`. This ensures that
SLA policies can be deleted reliably, regardless of data size.
### Problem
Deleting an SLA policy via `DELETE
/api/v1/accounts/{account_id}/sla_policies/{id}` fails consistently with
`Rack::Timeout::RequestTimeoutException (15s)` for policies with large
amounts of related data.
Because the current implementation performs all dependent deletions
**synchronously**, Rails processes:
- `has_many :applied_slas, dependent: :destroy` (thousands)
- Each `AppliedSla#destroy` → triggers destruction of many `SlaEvent`
records
- `has_many :conversations, dependent: :nullify` (thousands)
This processing far exceeds the Rack timeout window and consistently
triggers HTTP 500 errors for users.
### Solution
This PR applies the same pattern used successfully in Inbox deletion.
**Move deletion to async background jobs**
- Uses `DeleteObjectJob` for centralized, reliable cleanup.
- Allows the DELETE API call to respond immediately.
**Chunk large datasets**
- Records are processed in **batches of 5,000** to reduce DB load and
avoid job timeouts.
## Description
This PR fixes an issue where multiple consecutive newlines (blank lines
for visual spacing) were being collapsed in text-based messaging
channels like WhatsApp, Instagram, and SMS.
When users send messages via API with intentional spacing using multiple
newlines (e.g., `\n\n\n\n`), the markdown renderer was following
standard Markdown spec and collapsing them into single blank lines.
While this is correct for document formatting, messaging platforms like
WhatsApp and Instagram support and preserve multiple blank lines for
visual spacing.
The fix adds preprocessing to preserve multiple consecutive newlines
(3+) by converting them to placeholder tokens before CommonMarker
processing, then restoring the exact number of newlines in the final
output.
## Changes
- Added `preserve_multiple_newlines` and `restore_multiple_newlines`
helper methods to `MarkdownRendererService`
- Updated `render_whatsapp` to preserve multiple consecutive newlines
- Updated `render_instagram` to preserve multiple consecutive newlines
- Updated `render_plain_text` (affects SMS, Twilio SMS, Twitter) to
preserve multiple consecutive newlines
- Updated `render_line` to preserve multiple consecutive newlines
- HTML-based renderers (Email, Telegram, WebWidget) remain unchanged as
they handle spacing via HTML tags
## Type of change
- [x] Bug fix (non-breaking change which fixes an issue)
- [ ] New feature (non-breaking change which adds functionality)
- [ ] Breaking change (fix or feature that would cause existing
functionality not to work as expected)
- [ ] This change requires a documentation update
## How Has This Been Tested?
Added comprehensive test coverage:
- 3 new tests for multi-newline preservation across WhatsApp, Instagram,
and SMS channels
- All 56 tests passing (up from 53)
Testing scenarios:
- Single newlines preserved: `"Line 1\nLine 2"` remains `"Line 1\nLine
2"`
- Multiple newlines preserved: `"Para 1\n\n\n\nPara 2"` remains `"Para
1\n\n\n\nPara 2"`
- Standard paragraph breaks (2 newlines) work as before
- Markdown formatting (bold, italic, links) continues to work correctly
- Backward compatibility maintained for all channels
