title: Plaid Public Exchange Token Response
body: <p>eg from their site
  {
  &quot;access_token&quot;: &quot;access-sandbox-de3ce8ef-33f8-452c-a685-8671031fc0f6&quot;,
  &quot;item_id&quot;: &quot;M5eVJqLnv3tbzdngLDp9FL5OlDNxlNhlE55op&quot;,
  &quot;request_id&quot;: &quot;Aim3b&quot;
  }</p>
  <p>My question is what is &quot;item_id&quot; and why it keeps changing on repeated requests. I understand that &quot;access_token&quot; to change on repeated requests.
  This is what Plaid documentation says
  &quot;item_id - string
  The item_id value of the Item associated with the returned access_token&quot;</p>
  <p>How what should I treat this Item_Id as? InstitutionID?</p>
