Response Fields

Field	Type	Description
`cohorts`	array	List of LTV cohort records
`cohorts[].cohort_date`	string	First purchase date of the cohort (YYYY-MM-DD)
`cohorts[].customers`	number	Number of customers in the cohort
`cohorts[].periods`	array	Revenue data for each subsequent period
`cohorts[].periods[].period`	number	Period number (0 = first purchase period, 1 = next period, etc.)
`cohorts[].periods[].cumulative_revenue_per_customer`	number	Cumulative revenue per customer up to this period (in account currency)
`summary.average_ltv_30d`	number	Average customer LTV at 30 days across all cohorts
`summary.average_ltv_90d`	number	Average customer LTV at 90 days across all cohorts

Understanding LTV Cohorts

Each cohort represents customers grouped by when they made their first purchase. The periods array shows how cumulative revenue per customer grows over time:

Cohort	Period 0	Period 1	Period 2
Jan 2026	$48.50	$72.30	$89.15
Feb 2026	$52.10	$78.90	-
Mar 2026	$55.20	-	-

Period 0 represents the initial purchase. Each subsequent period adds revenue from repeat purchases, giving you a clear view of how customer value compounds over time.
