403 and no customer or applicant is made —
there is nothing to clean up afterwards.
403
What is checked
The country on the customer being created — an individual’scountry, or a
business’s company.country.
Who controls the list
The allow/deny list is two-tier: a platform-wide list, plus an optional per-partner list layered on top. Both are managed by Endl operations through an internal service API.This is not something a partner can set or read. There is no partner-facing
endpoint for country restrictions. If you need a country enabled, ask Endl
rather than looking for an API.
Handling it
Treat403 from create as a policy decision, not a transient fault — retrying
will not help, and neither will changing another field.
Because the check runs first, a 403 here means the rest of your payload was
never evaluated. Fixing the country may simply surface validation errors that
were waiting behind it.
