# Migration API Overview

> The Migration API provides a way for partners to import external members, accounts and transactions into the MX platform.

The Migration API provides a way for partners to import external `members`, `accounts` and `transactions` into the MX platform. These \`accounts will have typically been aggregated through Yodlee, Intuit or other third party aggregators prior to moving to the MX platform.

The Create Member endpoint requires a valid MX `institution_guid` be provided as part of the request. The `institution_guid` is an MX-provided value that identifies the Financial Institution the data came from. The list of available `institution_guid` values may be obtained from MX. The list is updated periodically so the list of i`nstitution_guid` values that will be used during a migration should be verified with MX prior to running the migration.

The MX Migration API is organized around REST. It is designed to have predictable, resource-oriented URLs and to use HTTP response codes to indicate API errors.

The Migration API supports both `xml` and `json` encoding of the request and response bodies.
