}Frequently asked questions
How do I know when my list is finished?
How do I know when my list is finished?
Poll this endpoint until
status is ready. At that point actual_count holds the real row count, credits_charged holds what you paid, and can_preview and can_download both flip to true.Why is actual_count lower than estimated_count?
Why is actual_count lower than estimated_count?
The estimate is a fast approximation; the actual count is what the query really matched. You are charged on the actual count, so a lower number costs you less.
What are can_preview and can_download for?
What are can_preview and can_download for?
They save you from encoding status rules on your side. Both are
true only when the list is ready — processing, failed and expired all yield false.Authorizations
API key in format tapi_live_[32-char] (live) or tapi_test_[32-char] (test)
Path Parameters
The lead list id.
Example:
