PATCH/api/v1/vendors/{id}

Update a vendor

Scope: vendors.update

PATCH validates against the full vendor schema (same as create) — displayName is required in every update, not just changed fields. The MSME block (msmeType, udyamNumber, msmeAgreedCreditDays) is only written when the body names at least one of those fields, and is then replaced as a unit; send msmeType: null to clear it. msmeAgreedCreditDays null means no written agreement (15-day rule); the maximum is 45.

Parameters
