Change the Default Payment Method {#tms-wallet-change-default-pay}
==================================================================

Use the `TMS` API in your e-wallet app to change the customer's default payment method.

1. To get all payment methods, call: `GET /tms/v2/customers/`*{customerTokenId}*`/payment-instruments`.

   #### ADDITIONAL INFORMATION

   The first result is the default payment instrument. The remaining payment methods are the non-default payment methods.

2. To make a non-default payment method the default, call: `PATCH /tms/v2/customers/`*{customerTokenId}* `/payment-instruments/`*{paymentInstrumentTokenId}* and set the value of the request field `default` to `true`.
