A merchant can provide evidence for disputes with the WAITING_FOR_SELLER_RESPONSE status while customers can provide evidence for disputes with the WAITING_FOR_BUYER_RESPONSE status. Evidence can be a proof of delivery or proof of refund document or notes, which can include logs. A proof of delivery document includes a tracking number while a proof of refund document includes a refund ID. For other evidence type, notes and documents can be given. Evidences requested from you can be found by checking the type of evidence for the corresponding source under the evidence section of the show dispute details response. The source will be REQUESTED_FROM_SELLER for evidences requested from the merchant while it will be REQUESTED_FROM_BUYER for evidences requested from the customer. For constraints and rules regarding documents, see documents.
To make this request, specify the evidence in the JSON request body and use the provide-evidence link in the HATEOAS links of the show dispute details response. In case the link is not present in the response, you can't provide evidence for the dispute. For information about dispute reasons, see dispute reasons. ## OpenAPI ````yaml /api-reference/customer_disputes_v1.json post /v1/customer/disputes/{id}/provide-evidence openapi: 3.0.3 info: title: Disputes description: >- Occasionally, something goes wrong with a customer's order. To dispute a charge, a customer can create a dispute with PayPal. PayPal merchants, partners, and external developers can use the PayPal Disputes API to manage customer disputes.
Note: In the live environment, merchants cannot create disputes but can only respond to customer-created disputes. However, merchants can create disputes in the sandbox environment. When you create an app, enable Disputes in the App feature options section.
A customer can also ask his or her bank or credit card company to dispute and reverse a charge, which is known as a chargeback. For more information, see Disputes, claims, chargebacks, and bank reversals.

When a customer disputes a charge, you can use this API to provide evidence that the charge is legitimate. To provide evidence or appeal a dispute, you submit a proof of delivery or proof of refund document or notes, which can include logs.

Normally, an agent at PayPal creates a dispute, updates the dispute status, and settles disputes, but now you can run test cases in the sandbox that complete these operations.

Important: The create, cancel, compute metrics, change reason, and validate eligibility methods are available as a limited-release solution at this time. For more information, reach out to your PayPal account manager.
