# Adds support for Mastercard compliance disputes ## What’s new Adds Mastercard compliance dispute support to the [Disputes API](https://docs.stripe.com/api/disputes.md?api-version=2026-06-24.dahlia). You can identify these disputes when `enhanced_eligibility_types` contains `mastercard_compliance`, or when `payment_method_details.case_type` is `compliance`, and the `reason` is `noncompliant`. The `evidence_details.enhanced_eligibility.mastercard_compliance` object contains a `status` value of either `requires_fee_acknowledgement` or `fee_acknowledged`. To contest a Mastercard compliance dispute, include `evidence.enhanced_evidence.mastercard_compliance.fee_acknowledged` set to `true` when you submit evidence. ## Impact If your integration automatically submits dispute evidence, check for `mastercard_compliance` in `enhanced_eligibility_types` before submitting evidence. For Mastercard compliance disputes, close the dispute without incurring the network fee or update your evidence submission flow to set `evidence.enhanced_evidence.mastercard_compliance.fee_acknowledged` to `true`. After you acknowledge the fee and submit evidence, `evidence_details.enhanced_eligibility.mastercard_compliance.status` changes to `fee_acknowledged`. We collect the Mastercard compliance network fee asynchronously and refund it if you win the dispute. ## Changes #### REST API | Parameter | Change | Resources or endpoints | | --- | --- | --- | |
