> Track all notable changes to the Grid API

<Update label="February 2026" description="Payment Intent: Fee Config (Breaking Change)">
  ### Breaking Changes

  * **Payment Intent Fee Config**: The `create_payment_intent` endpoint requires a `fee_config` field for non-enterprise tier customers. This field specifies who pays the transaction fee and in which currency. Requests without `fee_config` will return a `missing_fee_config` error.
    * [Create Payment Intent - Fee Config Migration](/grid/v1/api-reference/endpoint/payment-intents/post#fee-config-breaking-change)
</Update>
