Response

Lead updated

Code	Returned by	Meaning

STATUS_NOT_APPLIED	POST /leads (201)	The referral was created, but the requested status could not be applied. It stays in the status the message names; finish with PUT /leads/{identifier}.
EXISTING_REFERRAL_NOT_UPDATED	POST /leads (200)	A referral already carried the CRM record you sent and was returned unchanged. The message lists the fields from your request that were not applied.
REWARD_ATTRIBUTION_UNCHANGED	PATCH/PUT /leads/{identifier} (200)	The referral was reassigned to another partner contact, but rewards already calculated still pay the previous contact.
