FAQ

Questions about Trello + Asana.

When does Asana + Trello sync make sense?

When parts of the org work in Asana (formal project management) and others in Trello (lightweight kanban). The sync keeps cross-team work visible to both audiences without forcing tool migration.

How do I map Asana sections to Trello lists?

Maintain a (asana_section_gid → trello_list_id) lookup. The workflow consults the lookup at Create Card time. Updating section in Asana triggers Trello Move Card with the new list ID.

Can I sync Asana custom-field values into Trello labels?

Yes. Trello labels have IDs. Maintain a lookup of asana_custom_field_value → trello_label_id. Apply via Add Label to Card. Labels must exist on the Trello board first.

How do I keep Asana and Trello assignees in sync?

Maintain a lookup of asana_user_email → trello_member_id. Apply via Add Member to Card. Asana side: store the trello_member_id back so reverse-sync works too.

How do I avoid duplicate cards/tasks during sync?

Store the foreign ID as a custom field on each side. Asana custom_field "Trello Card ID"; Trello card's custom_field "Asana GID". Upsert by looking up the foreign ID before deciding create vs. update.

Will Asana attachments make it to Trello?

Yes. Loop over Asana attachments, pass each URL into Trello Create Card's urlSource (or call Add Attachment after creation). Trello renders link previews for common image and doc types.
