Crowdin manages your translations; Slack is where product, localisation and engineering coordinate a release. FlowMattic posts Crowdin's milestones to the right channel: a language is fully translated, a file is reviewed, new source strings need work, an export changed. Release managers know when a locale is ready to ship, and translators hear about new work without checking the project page.

1. TriggerProject Fully Translated2. ActionSend Channel MessageWhen Crowdin fires Project Fully Translated, FlowMattic runs Send Channel Message in Slack with the data from that event.

Each one uses only triggers and actions the two integrations ship today, plus FlowMattic's own tools. Where the library has a ready-made template, import it instead of building from scratch.
Ready-made templateA fully translated project is the signal that a release can include every language. The release channel hears it with the project name, so nobody has to check progress bars by hand.
Project Fully TranslatedSend Channel Message
View the template In file-based projects, each file that is fully translated goes to the proofreaders' channel with its name and language, so review starts on that file while others are still being translated.
File Fully Translated (Specific to file-based projects)Send Channel Message
Exported Translation Updated means the files the app ships with are different. Developers get a note in their private channel to pull the new strings into the next build.
Exported Translation UpdatedSend Private Channel Message
When a proofreader disapproves a suggestion, the translators' channel sees the string and language, so the translator learns the preferred wording and the same mistake is not repeated across files.
Suggested Translation DisapprovedSend Channel Message
A Router reads the task's target language and posts the new status to that team's channel, so the French and Japanese vendors each follow only their own tasks.
Task Status ChangedRouterSend Channel Message
When proofreading finishes for the whole project, the channel topic changes to say it is ready to ship, which is the first thing anyone joining the channel reads.
Project Fully ReviewedSet Channel Topic
At the end, the release channel hears each time a Crowdin project reaches full translation.
Under Connects, add Slack with an account that is a member of the release channel.
Create a workflow with Crowdin's Project Fully Translated trigger and follow the trigger's instructions to link your Crowdin project.
Finish the last strings in a small test project, or wait for a real milestone, so FlowMattic captures the project and language fields.
Add Send Channel Message, choose the release channel and map the project and language into the text. Test it and switch the workflow on.

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.
Crowdin and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.
Release managers see which languages are translated and reviewed in Slack, so a ship date is set from Crowdin's actual state.
New strings, rejected suggestions, finished files and changed exports go to the people who act on them.
FlowMattic runs on your own WordPress site, so a project with thousands of string events costs the same as a small one.
Create a FlowMattic workflow with a Crowdin trigger such as Project Fully Translated, then add Slack's Send Channel Message. Capture a test event, map the project and language into the message, and switch the workflow on.
Yes. Put a Router after the trigger with a path for each target language, each with its own Send Channel Message. This suits teams that work with a separate vendor per language.
Those two triggers only run in file-based Crowdin projects. If your project is string-based, use Project Fully Translated or Project Fully Reviewed instead.
Source String Added runs once per string. To keep the channel quiet, send those events to a dedicated channel, or store them with WP Tables and post a list from a separate scheduled workflow.
