Errors

Code	HTTP status	When	What to do
`validation_failed`	400	The tax ID's ID or another field is malformed.	Fix the fields listed in `details.issues` and send the request again.
`resource_not_found`	404	You have no such tax ID (another customer's reads the same).	Check the ID and that your credentials are scoped to the right organization, entity, brand and mode.
`customer_deleted`	400	Your account was deleted by the brand.	Create a new customer for this buyer. Deleted customers stay readable for the records they belong to, but can't be changed.
`version_conflict`	409	Your details changed at the same moment; retry.	Fetch the object again and retry the change.
`livemode_not_allowed`	403	The portal session is in the other mode than the request.	Use test mode, or credentials for the target's mode. Developers need live access granted by an organization owner or admin.
`permission_denied`	403	The caller isn't a customer signed in to this brand's portal (operators and API keys use the customer operations).	Ask an organization owner or admin for a role or scope that allows this action.

It can also return these common errors: api_version_unsupported, invalid_json, unsupported_media_type, authentication_required, api_key_invalid, scope_required, idempotency_key_reused, idempotency_in_progress, dry_run_not_supported, rate_limited, internal_error.
