# Lokalise + Slack integration > Connect translation workflows to real-time team communication by integrating Lokalise with Slack on tray.ai. **Canonical page:** https://tray.ai/connectors/lokalise-slack-integrations/ **Lokalise connector:** https://tray.ai/connectors/lokalise-integrations/ **Lokalise documentation:** https://tray.ai/documentation/connectors/service/lokalise **Slack connector:** https://tray.ai/connectors/slack-integrations/ **Slack documentation:** https://tray.ai/documentation/connectors/service/slack ## Overview Lokalise is the go-to localization platform for engineering, product, and translation teams handling multilingual content at scale. Slack is where those same teams actually spend their day. When the two run separately, important localization updates — new strings, completed translations, reviewer approvals, missed deadlines — get buried in project dashboards that most people rarely open. Integrating Lokalise with Slack on tray.ai means every meaningful event in your localization pipeline surfaces instantly in the right channel, so developers, translators, and product managers stay in sync without chasing each other down. Localization projects are cross-functional by nature — developers pushing new copy, translators working against tight deadlines, QA reviewers checking tone and accuracy, product managers tracking launch readiness across multiple languages. Without a real-time link between Lokalise and Slack, teams fall back on manual check-ins, status emails, or periodic dashboard logins to understand where things stand. That creates lag, missed blockers, and the kind of last-minute scrambles nobody wants before a product release. Automating Lokalise events into targeted Slack channels — and triggering Lokalise actions from Slack — cuts context-switching, surfaces translation issues earlier, and gets localized products out the door with far less coordination overhead. ## Use cases ### Instant Slack Alerts When New Strings Are Added to Lokalise Whenever a developer or product manager adds new translatable strings to a Lokalise project, a Slack notification goes out automatically to the relevant localization or translation team channel. Translators don't need to poll the platform for new work, and strings don't sit unassigned for days. Teams can scope alerts by project, language pair, or tag to keep things signal, not noise. - Translators hear about new work right away, cutting idle time between string creation and translation kickoff - Fewer strings go unnoticed or sit without an assignee - Slack messages can include deep links straight into the Lokalise editor for one-click access ### Slack Notifications for Translation Task Completions When a translator marks a task or batch of strings as complete in Lokalise, an automated Slack message goes to reviewers, project managers, or QA team members to kick off the next stage. The handoff between translation and review is clean and visible. No more manually chasing status updates across email threads or project management tools. - Review and QA cycles start faster because reviewers are notified the moment work is ready - Project managers get real-time visibility into completion milestones without logging into Lokalise - Slack thread replies can be used to acknowledge and claim review assignments ### Escalation Alerts for Overdue Translation Deadlines When a Lokalise task deadline passes and strings are still untranslated or unreviewed, tray.ai sends an escalation alert to a Slack channel and tags the relevant assignees or team leads. It's the kind of proactive catch that stops a localization blocker from quietly derailing a product launch. Teams can set custom escalation thresholds — say, 24 hours before and again at the moment of breach. - Product launches are protected because blockers get caught before they turn critical - Accountability improves with direct Slack mentions tied to overdue assignments - Teams can set tiered escalation rules to match their release cadence and SLAs ### Daily or Weekly Localization Progress Digests in Slack Instead of flooding channels with individual string-level events, tray.ai can aggregate Lokalise project data and post a scheduled summary digest to a dedicated Slack channel — overall translation progress, pending reviews, upcoming deadlines across all active projects. Stakeholders get a clean snapshot of localization health without anyone needing to log into Lokalise. Digests can be scoped by team, language, or project portfolio. - Leadership and cross-functional stakeholders stay informed without touching Lokalise directly - Digest format cuts notification fatigue compared to per-event alerts - Teams can schedule digests to line up with standups, sprint reviews, or release planning meetings ### Slack Alerts When Translations Are Reviewed and Approved When a reviewer approves translated strings in Lokalise, a Slack notification goes automatically to the developer or release manager responsible for pulling the latest translations into the application. It's a clean, auditable signal that translations are production-ready, closing the loop between the localization team and engineering. No more guessing whether it's safe to deploy. - Engineering teams know exactly when approved translations are available for integration - Cuts the back-and-forth between developers and localization leads about translation readiness - Approval events can trigger downstream steps like CI/CD pipeline notifications or file exports ### Notify Slack When a New Lokalise Project or Language Is Created When a new project is created in Lokalise or a new target language is added to an existing one, an automated Slack message alerts the full localization team or relevant project stakeholders. This matters especially for fast-scaling companies that regularly launch in new markets. Stakeholders are in the loop from day one without anyone having to manually broadcast the news. - New localization initiatives are visible to all stakeholders from the moment they're created - Teams can immediately start planning resourcing, timelines, and translation memory setup - Reduces the risk of new projects flying under the radar and missing early-stage planning ### Slack-Triggered Lokalise Actions via Slash Commands or Workflows With tray.ai, teams can configure Slack slash commands or Workflow Builder triggers to act directly in Lokalise — creating a new translation task, fetching the current completion percentage of a project, or reassigning an overdue task to a different translator. Slack becomes a lightweight control surface for localization operations, without needing to switch apps for routine management tasks. - Project managers can handle routine Lokalise operations without leaving Slack - Fewer applications to context-switch between during busy release cycles - Slash command outputs can be shared in-channel, making localization status visible to the whole team instantly ## Templates ### New Lokalise String → Slack Channel Notification Automatically posts a formatted Slack message to a designated localization channel whenever new translatable strings are added to a specified Lokalise project, including the string key, source text, and a direct link to the editor. Connectors used: Lokalise, Slack ### Lokalise Task Completed → Notify Reviewer in Slack When a translator marks a task as complete in Lokalise, tray.ai automatically sends a direct Slack message or channel notification to the assigned reviewer, prompting them to begin the review stage with a link to the relevant strings. Connectors used: Lokalise, Slack ### Overdue Lokalise Deadline → Slack Escalation Alert On a scheduled interval, tray.ai checks Lokalise for tasks or projects with deadlines that have passed or are within a configurable warning window, then posts escalation alerts to Slack, mentioning the assigned translators and project leads. Connectors used: Lokalise, Slack ### Weekly Lokalise Progress Digest → Slack Summary Post Every Monday morning, tray.ai pulls translation completion statistics from all active Lokalise projects and posts a structured digest to a Slack channel, summarizing per-project progress percentages, pending reviews, and upcoming deadlines for the week. Connectors used: Lokalise, Slack ### Lokalise Translation Approved → Notify Engineering in Slack When strings in Lokalise are marked as approved by a reviewer, tray.ai automatically sends a Slack message to the engineering or release management channel, signaling that the latest translations are production-ready and can be integrated into the application. Connectors used: Lokalise, Slack ### New Lokalise Project Created → Slack Team Announcement Automatically broadcasts a Slack announcement to the localization team channel whenever a new project is created in Lokalise, including the project name, source and target languages, and the project owner, so all stakeholders are in the loop from the start. Connectors used: Lokalise, Slack ## Challenges Tray.ai solves ### Mapping Lokalise Users to Slack Users for Targeted Notifications Lokalise and Slack maintain separate user directories, and translator or reviewer names in Lokalise don't automatically correspond to Slack user IDs. Without a reliable mapping, notifications can't reach the right individuals, so teams end up falling back on channel-wide broadcasts instead of direct @mentions. **How Tray.ai helps:** tray.ai lets you build and maintain a user mapping table inside your workflow — either as a static lookup or pulled dynamically from an HR system or spreadsheet — so every Lokalise event reaches the correct Slack user or group with accurate @mentions and direct messages. ### Managing Notification Volume Without Creating Alert Fatigue Lokalise projects can involve thousands of individual string events. Routing every key creation, update, or status change to Slack would overwhelm channels fast, and once people start muting notifications, the whole integration loses its value. **How Tray.ai helps:** tray.ai's workflow logic lets you apply filters, aggregation windows, and conditional branching so only meaningful events — task-level completions, deadline breaches, approval milestones — actually surface in Slack. Digest-style rollups can batch individual events into a single scheduled summary instead. ### Handling Webhooks Reliably Across Multiple Lokalise Projects Teams running many Lokalise projects simultaneously need reliable event delivery from each one, but configuring and maintaining individual webhooks at scale gets brittle — especially when project structures change often as new markets and products are added. **How Tray.ai helps:** tray.ai provides a stable webhook endpoint that can receive events from multiple Lokalise projects at once, with built-in retry logic and error handling so no events get dropped. A single tray.ai workflow can route events from any number of projects to the right Slack channels based on configurable routing rules. ### Keeping Slack Notifications Useful Without Cluttering Messages Raw Lokalise webhook payloads are full of technical fields that make sense to an API but are confusing or irrelevant to translators, reviewers, and project managers reading Slack. Poorly formatted notifications erode trust in the integration quickly. **How Tray.ai helps:** tray.ai's data transformation tools let you reshape Lokalise event payloads into clean, readable Slack messages using Block Kit formatting — bold project names, progress indicators, language flags, clickable deep links — so every notification is immediately actionable for any team member. ### Triggering Lokalise Actions from Slack in a Secure and Governed Way Letting team members trigger Lokalise operations from Slack raises real questions about authentication, permissions, and auditability — especially in enterprise environments where only certain roles should be able to reassign tasks, create projects, or modify deadlines. **How Tray.ai helps:** tray.ai lets you build role-aware workflows that check the Slack user initiating a command against an allowlist or SCIM directory before executing anything in Lokalise. All actions are logged in tray.ai's execution history, giving you a complete audit trail of who triggered what and when. ## Learn more - Intelligent Integration: https://tray.ai/platform/intelligent-ipaas/ - Merlin Agent Builder: https://tray.ai/platform/merlin-agent-builder/ - Agent Gateway for MCP: https://tray.ai/platform/agent-gateway/ - Book a demo: https://tray.ai/contact/
