SPLIT_TEST_CONFLICT Split Test Configuration Error

Your A/B (split) test setup has conflicting parameters—either the test groups aren't properly isolated, the budget allocation percentages don't sum to 100%, or you're trying to test incompatible variables simultaneously.

What causes this error?

Your A/B (split) test setup has conflicting parameters—either the test groups aren’t properly isolated, the budget allocation percentages don’t sum to 100%, or you’re trying to test incompatible variables simultaneously.

How to fix it

1. Budget split: Ensure test group budget allocations total exactly 100%.
2. Single variable: Only test one variable at a time (e.g., creative OR audience, not both).
3. Audience isolation: TikTok automatically splits audiences for you—don’t manually create overlapping audience targeting between test groups.
