TikTok API Identifiers: creator and post IDs

Creator IDs

Every creator can be addressed two ways. Both resolve to the same record:

TikTok username — convenient and human-readable, but a creator can change it on TikTok at any time.
Tokfluence creator ID — a stable opaque string we mint and never change. Format: tkc_ followed by 16 lowercase hex characters.

http

# Both of these return the same creator
GET /v1/creators/wwe
GET /v1/creators/tkc_a1b2c3d4e5f6a7b8

Best practice

Use the username for ad-hoc lookups and customer-facing UI. Store the tkc_ id in your database as the canonical reference.

Post IDs

Posts are addressed by their TikTok video ID — the trailing numeric segment of a TikTok URL:

https://www.tiktok.com/@wwe/video/7234567890123456789
                                       ^^^^^^^^^^^^^^^^^^^
                                       This is the post ID

Campaign IDs

Campaigns are addressed by integer IDs scoped to your account. A campaign created via the API and one created via the Tokfluence app share the same numbering — they're the same entity under the hood (a "list" with tracked posts).
