Bigin creates a new contact on every API create, even for a duplicate email
Two or more contacts share one email
Verified 2026-07-18 · Confirmed by 0 builders · Trust 50/100
Cause
The create endpoint does not deduplicate contacts by email.
Fix
Search by email before creating, and update the existing contact when one is found.
Apply
GET /bigin/v2/Contacts/search?email=<email>; create only when the response is 204
Affects: Bigin API v2 and Make createAcontact, July 2026
