My question was not related to usage of API call. I want to setup lookup keys for each user. When i do this by DreamFactory admin interface, i'm adding a new lookup key, indicate its name (for exmple, "Key1") and value (for example, "1"). And its working.
But, i need to create this key automatically for each user, when user registers. I think, i can do it by SQL trigger in database layer and the result, there is not need to change DreamFactory php-scripts. But when i see lookup keys in database table, which where created by DreamFactory admin interface, i see values like "3BoL5oV75bzrHKdLSyU8Tm75DhA79ScGr9I1l1jIa9o=" and i realise, that value was encrypted.
How can i generate lookup keys automatically for each user?
