Saves a badge address on your team and answers the team. The badge comes from POST /api/onboarding/generate-badge.

Who: a signed-in player with a team.

Refusals:

  • badge_ipfs_uri must be in format 'ipfs://<cid>': the value does not start with ipfs:// or is shorter than 10 characters.
  • User not found: the wallet has no account.

A wallet without a team gets HTTP 404 with an empty body. If the team cannot be saved on our side, the answer is HTTP 500 with an empty body.
