Ankit reported getting a 202 'Accepted' response from the legacy v1 batch contact update API (/contacts/v1/contact/batch/) but the contacts weren't actually updated. Asked how to find errors.

Joe Conery explained 202 means the request was accepted for asynchronous processing, not guaranteed success. He suggested checking for a status query endpoint (unlikely for v1) or re-querying the data after a delay. Using the v3 batch APIs is recommended for better status handling.
