Types of fields in the database

Default database fields

This table provides a list of default database fields, their API matches, data types, and examples of values that can be used.

Field in the database	Field name in the API	Field type in the UI	The type of the field in the API	Example of the value
Email	email	Line/Email	string	"example@example.com"
Phones	phones	Phone list	array	["+79001234567"]

Last name	_lname	Line	string	"Doe"
Date of birth	_bdate	Date	string	"2001-12-31" "2001-12-31T00:00+03:00" The time can only be transmitted via the API.
Gender	_sex	Enum	string	"male" "female"
Date of reg.	_regdate	Date	string	"2023-12-31" "2023-12-31T23:59:59+03:00"

Time zone	_tz	Line	string	"Europe/Moscow"
Supplier	_vendor	Line	string	"form #30"

Custom database fields

The type of field determines which operators will be available in segments and in dynamic template variables, so we recommend carefully choosing the type of additional field in the database.

Field type in UI	Field type in API	Example of the value
Integer	int	100
Float	float	100.5
Line	string	"string value"
Date	string	"2024-05-27T12:00:00Z"
Boolean	boolean	true false
Enum	string	"Option 1" You can also pass a value as a number, for example, 1. The number corresponds to the ordinal number of the item in the list.
IP	string	"127.0.0.1"
Tags	array	["Tag 1", "Tag 2", "Tag 3" ]
Object	object	{ "key_1": { "sub_key": "sub_value" } }
Array of objects	array of objects	[ { "key_1": "value_1" }, { "key_2": "value_2" } ]

Acceptable formats and restrictions

The platform expects certain value formats for each type of field. Make sure that the imported data meets the specified requirements, otherwise the system will not be able to process them correctly.

• Email — the format must comply with RFC standards. A regular expression is used for validation:

^[-a-z0-9!#$%&'*+/=?^_{|}~]+(\.[-a-z0-9!#$%&'*+/=?^_{|}~]+)*@((?:localhost|([a-z0-9]([-a-z0-9]{0,61}[a-z0-9])?\.)*([a-z]{1,24})))$

• Phones — the number must correspond to the international format (without spaces, hyphens and other separators, except for the plus sign at the beginning). More information about the standard can be found in this article.

• Dates — are recorded in the format RFC 3339 (ISO 8601) indicating the time zone.

• Country — accepted as a two-letter code ISO 3166-1 alpha-2 or the full name (in any case).

• Gender — acceptable values are described in this article.

• Provider — the length of the string is no more than 26 characters.

• IP — IPv4 format.

• Line — it is not recommended to store more than 100 KB of text in one field.

• Objects and arrays of objects — you can write only peer-to-peer objects or peer objects nested in other objects. If you are using objects with a more complex structure, connect the SQL database and create queries to select profiles. In object field names, only Latin letters (in any case), digits from 0 to 9, the underscore _, and the hyphen - are allowed.

• The limit on the amount of data of one profile in the database is 16 MB, including all metadata. However, it is not recommended to store a total of more than 2 MB in additional profile fields.

Matching of database fields and form elements

If you are configuring profile data import from form fields to database fields, make sure that you are using the correct field type for each form element.

Form element	Field in the database
Short text	Custom field with the “String" type
Email	Default ”Email" field
Phone number	Default field “Phones”
Long text	Custom field with the “String" type
Number	Custom field with the “Integer” type
Yes/No	Custom field with the “Boolean” type
One choice	Custom field with the “String" type
Multiple choice	Custom field with the “Tags" type
Drop-down list	Custom field with the “Tags" type
Date	Default or custom field with the “Date” type
Range	Custom field with the “Integer” type

note

Although you can write all user data in string fields, this will limit the possibilities for further segmentation. For example, if the date is written in a string field, you will not be able to use the comparison operators "date less" or "date more" in segments or templates.
