Douyin mini-game: ISBN before virtual payment
Douyin Open Platform资质 docs treat the NPPA publication number (版号 / ISBN) as the key credential for opening mini-game in-app purchase; soft著 and operator-name match still apply.
Douyin’s developer FAQ 小游戏审核常见问题-资质篇, opened 20 September 2026, states that creating a mini-game requires the legally required credentials, including the software copyright certificate and the 广电总局版号批文. On 版号 it is explicit: the publication approval is 小游戏开通内购能力的重要凭证 (an important credential for opening in-app purchase). Operators must complete the 网络游戏出版物号 (ISBN) fields in the stated format and bind the 中宣部备案识别码 to the 北京抖音信息服务有限公司 system.
Checklist before promising Douyin IAP UA
| # | Check | Documented rule |
|---|---|---|
| 1 | ISBN / 版号批文 uploaded | Required credential path for opening IAP capability |
| 2 | ISBN string format | Follow the on-page format example for 网络游戏出版物号 |
| 3 | Mini-game display name ≡ name on 版号 materials | Must match exactly, including suffixes such as “游戏软件” where present on the credential |
| 4 | Operating-unit name on 版号 ≡ Douyin subject name | Else upload authorisation under the optional 授权书 entry |
| 5 | Software copyright (软著) present | Separate mandatory upload; one 软著 supports only one live mini-game on the platform |
| 6 | 软著 copyright owner ≡ platform subject (or authorisation) | Mismatch needs authorisation letter |
| 7 | 中宣部备案识别码 bound to Douyin’s designated system | Page requires binding to 北京抖音信息服务有限公司 |
| 8 | Paid UA creatives only after IAP资质 is actually open | Platform page is about audit credentials, not ad-account spend approval |
Limits
The FAQ explains credential audit for mini-game creation and IAP enablement. It does not publish Ocean Engine bid floors, nor does it say an ISBN alone guarantees traffic. Diamond / virtual-payment technical guides are adjacent docs; this checklist stops at the ISBN gate stated on the资质 page.
