Anrok address requirements Report an error

“Anrok requires a customer address to resolve the tax jurisdiction. If the address Lago sends is missing required fields, Anrok can't determine the applicable tax rate, and Lago emits a customer.tax_provider_error webhook.”
Anrok address fields sent Report an error

“Lago sends address_line_1, city, zip, and country to Anrok. It uses the customer's shipping address first, falling back to the billing address only when shipping address fields are entirely absent.”
Anrok partial shipping address Report an error

“If a shipping address is partially populated, for example only shipping_country set, Lago sends those partial fields rather than falling back to a complete billing address. This is the most common source of unexpected failures.”
Anrok min fields by country Report an error

“US and Canadian customers need zip and country; customers in other countries generally need only country.”
Anrok state not sent Report an error

“state/region is not included in Lago's tax computation request to Anrok, so populating region alone will not unblock a failed tax call.”
Anrok resolve refresh invoice Report an error

“After updating, click Refresh invoice on the draft to trigger a new Anrok tax computation.”
Article not official Report an error
