Database Persistence

In case the user prefers using database persistence, MySQL can be used. The DB persistence mechanism is the default method in PHP SDK.

• The database name should be zohooauth.

• There must be a table oauthtokens with columns

  • useridentifier (varchar(100))

  • accesstoken (varchar(100))

  • refreshtoken (varchar(100))

  • expirytime (bigint)
