File Post-Import Processing Module

The post-import module allows you to modify the strings parsed from your files after the file import. This module works with both the source strings and their respective translations. The pre-import module is especially useful if you’d like to preserve the original file structure and parse it as it is but want to make some changes to source strings, context, string translations or add labels, and maximum length limits for translations, etc.

With the help of the post-import module, you will get a payload with the file content and strings parsed from it. Using the post-import module, you can modify the parsed strings in a number of ways (e.g., split, merge, or add new strings) and return the modified strings. This allows you to customize the strings without directly modifying the file content.

You can grant access to this module to one of the following user categories:

For Crowdin:

  • Only me (i.e., project owner)
  • All project members
  • Selected users

For Crowdin Enterprise:

  • Only organization admins
  • All users in the organization projects
  • Selected users

Properties

key

Type: string

Required: yes

Description: Module identifier within the Crowdin app.

url

Type: string

Required: yes

Description: The relative URL triggered on file import, update, and translation upload.

signaturePatterns

Type: object

Description: Contains fileName and/or fileContent regular expressions used to detect file type when uploading a new source file via UI (or via API without specified type parameter).

Note: fileContent regular expression checks only the first 64 KB of the file content.

Communication between File Processing App and Crowdin

When importing a file, the system detects an appropriate post-import module using the signaturePatterns parameter and makes an HTTP request to the app’s URL ($baseUrl . $url) for further processing containing the extracted strings.

The file processing app will modify the received strings according to your needs. The post-import module allows you to split, merge, add new strings, or edit the attributes of the existing ones. Once the modified strings are returned from the post-import module, they are added to the Crowdin project and become available for translation.
