Data standards
Money & timestamps
Two boring details that catch every integration off-guard at least once.
Money#
Always minor units. NGN is in kobo; 1500000 means ₦15,000.00. Display formatting belongs in your client, not the API.
Timestamps#
Pure ISO-8601 UTC for stored timestamps. Local-time fields (e.g. an appointment in Lagos) include the offset explicitly.
