Installed Event Communication Flow

When a Crowdin App is installed in the Account Settings the authorization flow takes place during which Crowdin and Crowdin App exchange the authorization data (the authorization code is being exchanged for an access token). In the following illustration, you can see the events that take place during this process.

Let’s examine in detail each step that happens in the illustration:

1. Installation of the Manifest URL - the user pastes in the Manifest URL in the Account Settings > Crowdin Applications and clicks Install.
2. Fetching content from the Manifest URL - the request is sent to Crowdin App.
3. Response: manifest JSON - Crowdin App returns the Manifest JSON that contains the data about the app.
4. Manifest Data Validation - the received content is validated according to the structure and data of the Manifest JSON.
5. Prompt to install - the information about the Crowdin App, as well as the list of permissions and the Install button is displayed to the user.
6. Confirmation of the installation - the user confirms the installation of the Crowdin App.
7. The Installed event - Crowdin sends the Installed event with the authorization code to the Crowdin App for API token generation.

8. Token request - Crowdin App sends the request for API token acquiring:
