Connect Localazy and Slack

Localazy sits between your code and your translators. FlowMattic tells Slack when new source keys arrive for translation, when translators leave a comment, when a release tag is promoted and when the project is published. For developers and localization managers who ship apps or websites in several languages and coordinate releases in Slack.

When Localazy fires Project Published, FlowMattic runs Send Channel Message in Slack with the data from that event.

Localazy and Slack workflows you can build

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 template

Tell the team when a Localazy project is published

The project name posts to the release channel when translations are published, so developers know the new strings are ready to pull into the build.

Project PublishedSend Channel Message

Alert translators when new source keys are imported

Content Imported fires when keys are added, updated or deprecated. Translators see in their channel that there is new text to work on before the release date.

Content ImportedSend Channel Message

Send translator comments to the developers

Translators often ask what a placeholder means or how long a label can be. Posting their comments to the dev channel gets them an answer from the person who wrote the string.

Comment AddedSend Channel Message

Announce promoted release tags

When a release tag is promoted, for example from staging to production, the release channel hears about it, so QA knows which translations are going live.

Tag PromotedSend Channel Message

Log imports that changed nothing in a quiet channel

Content Imported Empty confirms that an upload from your CI ran with no changes. A private log channel shows the sync is alive without disturbing translators.

Set up: publish alerts

At the end, every time a Localazy project is published your release channel gets a message with the project name.

Triggers and actions in this pair

A trigger starts a workflow. An action is something FlowMattic does in the app as a step.

Good to know

Webhooks in Localazy are set per project. Add the workflow's address to each project you want in Slack, or use one workflow per project.
Content Imported can fire on every CI run that changes keys. If that is too often, post to a translators channel rather than the main dev channel.
Event data is small, so the mapping above is an example. Capture an event and use Date/Time Formatter if you want a local time in the message.

Why run this pair with FlowMattic

Localazy and Slack connect through FlowMattic on your own site, with no separate automation account in the middle and no charge per run.

Translators hear about new text

New and changed keys reach the translators channel, so translation starts before the release deadline, not after.

Developers see questions sooner

Translator comments arrive where developers read, which cuts the wait for an answer about context.

Runs on your server

FlowMattic runs on your WordPress site with unlimited runs, so frequent CI imports cost nothing extra.

Common questions

How do I connect Localazy to Slack?

Create a FlowMattic workflow with a Localazy trigger such as Project Published, add the workflow's address as a webhook in the Localazy project, then add Slack Send Channel Message.

Can translators be told when there are new strings?

Yes. Content Imported fires when keys are added, updated or deprecated. Post it to the translators channel with the project name.

What is Content Imported Empty for?

It fires when an import finished with no changes. It is handy as a health check for automated uploads, posted to a quiet log channel.

Can each project post to its own channel?

Yes. Build one workflow per project, or use a Router on the project name so each project's events go to that team's channel.

Can a reminder be set when new keys arrive?

Yes. Add Add Reminder after the Content Imported step so the localization manager checks progress a few days before the release.
