TikTok Spark Ads limits: 10,000 per account and 20 codes a batch

TikTok allows a maximum of 10,000 Spark Ads per account, lets a creator authorize up to 20 video codes in one batch, and requires authorization codes from both creators when a post is a Duet or Stitch. If you are producing AI video variants for Spark, the 20-code batch is the limit that shapes your rollout first.

All figures are from TikTok's help article How to create Spark Ads for Smart+ Campaigns in TikTok Ads Manager, read 2026-10-02.

What are the numbers?

The page states them plainly, and each one turns into a planning constraint.

How do I batch AI variants for 20-code sets?

Name and track each variant before you publish, then authorize in groups. Sume jobs take an Idempotency-Key, so using a key per variant keeps a retry from producing a duplicate render. A set of 20 caption jobs at $0.20 each is $4.00 in caption cost for clips up to 60 seconds, plus $0.02 per trim.

for i in $(seq -w 1 20); do
  curl -s -X POST https://api.sume.com/v1/video-captions \
    -H "Authorization: Bearer $SUME_API_KEY" \
    -H "Content-Type: application/json" \
    -H "Idempotency-Key: spark-batch-$i" \
    -d "{\"video_url\":\"https://media.sume.com/artifacts/artf_demo/v$i.mp4\",\"style\":\"slam\"}"
done

Does the same-clip trap apply to AI variants?

TikTok does not say on this page that near-identical variants are penalised, so do not infer a rule from it. Separately, TikTok's content policies on unoriginal content are covered in reused AI video batches; make variants meaningfully different rather than re-captioned copies.

What does Sume not manage?

Sume does not request, store or renew Spark codes, and does not talk to Ads Manager. Poll jobs as in Jobs and results and track code expiry in your own sheet.
