Contract Unlinked Webhook Event

Straumur Team

A new Contract Unlinked webhook event is now available. This event fires whenever a merchant contract is unlinked from a partner contract, letting partners react to merchants leaving their agreement.

What's included​

The ContractUnlinked event provides:

  • The partnerContractNumber, ssn, merchantNumber, and contractNumber identifying the parties that were separated

Unlike ContractLinked, this event does not include a terminal list — only the contract identifiers are present in the payload.

HMAC signature​

The HMAC signature for ContractUnlinked is calculated over PartnerContractNumber, Ssn, MerchantNumber, ContractNumber — the same four-field signing path used by ContractLinked.

See the full documentation at Contract Unlinked Event.
