What can you do with Crowdin on Tray.ai?
Crowdin is a localization platform where teams upload source files and strings, run translators and machine translation over them, and export the translated versions. Tray.ai connects to Crowdin through the HTTP Connector, so your workflows can call the Crowdin API alongside the rest of your stack.
- When Crowdin sends “Project translated”, start a release build in your CI pipeline.
- When Crowdin sends “Task added”, notify translators in your team chat.
- Add a file whenever developers merge new source strings into your main branch.
- Build project translations before each scheduled release so your app ships in every language.
- Connects through
- HTTP Connector
- Authentication
- A bearer token or OAuth 2.0
- Base URL
- https://api.crowdin.com/api/v2
Set it up
Connect Crowdin to Tray.ai
Each step uses Crowdin's own API details, from its documentation.
Step 1
Save Crowdin's API token
Save the token Crowdin issues as a Tray.ai authentication. The HTTP Client sends it as a bearer token on every call. The token stays out of the workflow and out of the logs.
Step 2
Point the HTTP Client at the API
Add an HTTP Client step and use https://api.crowdin.com/api/v2 as the base URL. Or paste a cURL example from Crowdin's API docs, and Tray.ai fills in the method, URL, and headers.
Step 3
Start with “List projects”
It's one of 22 documented actions, under Projects. The response comes back as data the next step can map into your other apps.
Step 4
Start workflows from Crowdin events
Give Crowdin the URL of a Tray.ai webhook trigger. “File added” can then start a workflow, and so can 11 other events.
