Source Import API enhancements for working with Git LFS

Today we're introducing enhancements to the Source Import API to support importing repositories with files larger than 100MB.

Changes to parameters for starting an import

Starting an import no longer requires a vcs parameter. Please be aware that without this parameter, the import job will take additional time to detect the vcs type before beginning the import. This detection step will be reflected in the response.

New methods

We've added 3 new methods that will enable API consumers to:

  • update the authentication or project choice for an import. If no parameters are provided during the request, the import will be restarted. Please note that this is a breaking change. Updating authentication for the originating URL is no longer supported through the start an import method. Please update your applications to use the new method.

  • set their preference for using Git LFS to import files larger than 100MB.

  • list all the files larger than 100MB that were found during the import.

New attributes for Git LFS

Several new response attributes (use_lfs, has_large_files, large_files_size, large_files) were added to provide details regarding the large files found during the import. You can read more about the attributes here.

As before, to access the API during the preview period, you must provide a custom media type in the Accept header:
