Full dispute lifecycle updates are currently available for Adyen, Airwallex, Braintree, Checkout.com and PayPal. For other supported processors - currently Worldline Connect, Worldline Direct, MPGS, Payplug, Reach, Stripe, and Worldpay - you will only receive a Webhook with a
status of OPEN where the type is DISPUTE.type (Retrieval, Dispute, and Pre-arbitration), and status that depends on the type.
Every time the status or type is updated, a new DISPUTE.STATUS webhook will be sent.

Dispute lifecycle
Visa and Mastercard do not investigate payments before raising a dispute. As a result, these payment methods skip
RETRIEVAL and go straight to the DISPUTE event type.Dispute Types
As in the diagram above, Primer’s disputes framework separates disputes into three different types:RETRIEVAL, DISPUTE and PREARBITRATION
RETRIEVAL
ARETRIEVAL signifies an investigation into a payment has been launched. For cards, this is launched by a card issuer. Depending on the results of this investigation, a DISPUTE may be raised, and the payment can be reversed. This dispute type is not used by all payment methods or card schemes - Visa and Mastercard do not support it.
DISPUTE
ADISPUTE occurs when a payment is reversed by the payment method (card issuer) after a customer complaint.
The end customer will receive money back, and the processor will then debit the merchant the equivalent amount.
For card payments, this is also known as a chargeback.
PREARBITRATION
If a merchant successfully challenges a dispute, but the payment method (usually a card issuer) believes a further review is required, aPREARBITRATION dispute type will be opened.
This is effectively an ‘appeal’ process.
