SunLicense

itch.io ​

itch.io doesn't send purchase webhooks, so buyers come to you: they paste their download link on your redeem page, SunLicense checks it with itch.io's API, and shows their key. Asking again returns the same key.

Setup ​

  1. itch.io Settings → API keys → Generate new API key.
  2. SunLicense: Integrations → itch.io → Connect. Paste the API key and your game ID (from the game's edit page URL, or GET https://api.itch.io/profile/games). Map * to the policy buyers should get.
  3. Link the integration's redeem page from your game page, the download notes, or a README inside the download.

What buyers do ​

They paste the link from their purchase email or itch.io library (https://you.itch.io/game/download/<key>; the key alone works too) and the email they want the license under.

SunLicense calls GET /games/<game id>/download_keys?download_key=<key> and only accepts keys for your game. One license per download key.
