If you provide a business type that isn’t supported for the merchant’s country, we return the unsupported_business_type error code. You need to update the business type to a valid value.
### Create new accounts with the correct business type and company structure
When creating new accounts, make sure to provide a valid business type and company structure for the country. Doing so can prevent you from receiving any errors.
bash
# Correct approach for new accounts
curl -X POST https://api.stripe.com/v1/accounts \
-u sk_test_123: \
-d "country=NL" \
-d "type=custom" \
-d "business_type=company" \
-d "company[structure]=sole_proprietorship"
If you encounter the error on existing accounts, update the accounts to resolve the error.
bash
# Update existing accounts
curl -X POST https://api.stripe.com/v1/accounts/acct_123 \
