Square Authorization Flow and OAUTH Tokens Explained.

Square Authorization Flow and OAUTH Tokens Explained.

All our Square gateway integrations require Authorization in SuitePOS before transactions can take place.  This is known as the "obtainToken flow".

The following steps are involved using Square Authorization in the POS Settings Screen :
  • Get an Access_Token by logging into your Square Account from SuitePOS.
  • This Access_Token is then used to obtain a Refresh_Token. 
  • This Access_Token is then used to get the "Authorization _Code "which is then used for subsequent transactional SDK calls.
On every sync (at least once a day), SuitePOS will get a new "Access_Token" using the "Refresh_Token". The "Refresh_Token", under the "obtainToken flow", never expires.
Because tokens are stored in the secure Apple Keychain, these tokens persist through application removal and re-installs on the device.
