Improved
New validation rules for name fields in verification requests
November 20th, 2025
Previous validation rules for the first_name, last_name and legal person nameparameters could lead to situations where the verification remained stuck in a pending status.
To address this, we’ve introduced new validation rules for the following endpoints:
-
[POST /verifications/identity_documents] (see API reference)
-
[POST /verifications/bank_accounts] (see API reference)
-
[POST /verifications/proofs_of_address] (see API reference)
Updated validation rules
first_nameandlast_name:
^[('|’)]?[\d\p{L}\p{M}+][-\d\p{L}\p{M}+.'’ ]*$
- legal_person
name(only for the POST /verifications/bank_accounts) : maximum length of 128 characters
Impact of this change
Any verification request not complying with the new rules will now return a 400 Bad Request error.
We recommend reviewing your current integration to ensure compliance with the updated validation rules.
