I am trying to understand how taiga backend works. while importing data from trello the documentation doesn’t says anything on how data is imported. I also have gone through the codebase but didn’t found anything related to Trello Data import. Can anyone guide me to understand this process? The questions I have:

1. How exactly Taiga requests data from Trello?
2. where the API calls are made? if taiga uses any third party importer then where can I find it in the codebase?  
Thanks any help would be appriciated.

Hi @shakhawat1355

taiga does not use a third party lib, the code is in `taiga.importers` module in the backend.

> <https://github.com/kaleidos-ventures/taiga-back/tree/main/taiga/importers>
>
> //github.com/kaleidos-ventures/taiga-back/tree/main/taiga/importers

There are some common code for all the importers but the specific code with the specific calls is in `TrelloClient` class at [taiga-back/taiga/importers/trello/importer.py at main · kaleidos-ventures/taiga-back · GitHub](https://github.com/kaleidos-ventures/taiga-back/blob/main/taiga/importers/trello/importer.py). This class is instanciated and calle by a task defined at [taiga-back/taiga/importers/trello/tasks.py at main · kaleidos-ventures/taiga-back · GitHub](https://github.com/kaleidos-ventures/taiga-back/blob/main/taiga/importers/trello/tasks.py)

I hope this can help

Best regards

Thanks a lot. I didn’t know this repo existed.
