API Reference

Create entity record

This API is in beta. Endpoints, fields, and behavior may still change, so avoid depending on it in production.

Adds a record to one of the app’s entities and returns it.

Base44 stores only the fields the entity’s schema declares and drops the rest, so a misspelled name is left out of the record instead of failing the call. Base44 also assigns id, created_date, updated_date, created_by and created_by_id, and ignores them if you send them.

Row-level security applies, so an entity whose rls create rule doesn’t cover the record you send fails with a 403.

Don’t pass User as the entity_name. Base44 manages the app’s users through its own endpoints, and a record created here under that name is stored where those endpoints don’t read it.

Creating a record triggers the app’s webhooks and any automation or workflow that listens for this entity.

This endpoint is limited to 140 requests per minute per app.

This endpoint accepts a personal API key belonging to a user with access to the app. A read-only key is refused, and workspace API keys are not accepted.

Authorizations

api_key

string

header

required

Personal API key.

Path Parameters

app_id

string

required

ID of the app that owns the entity.

entity_name

string

required

Name of the entity, exactly as List entity schemas reports it.

Body

application/json

The record's fields, as a flat JSON object using the names the entity's schema declares.

Response

The created record.

One record in one of an app's entities.

string | null

ID of the record. Pass it as entity_id to Get entity record, Update entity record or Delete entity record.

Example:

"6886b8d390dc7e2f4a2c91b3"

created_date

string | null

When the record was created, as a UTC timestamp in ISO 8601 format. A record Base44 has just created carries a Z suffix, and a record read back from storage does not.

Example:

"2026-06-01T09:23:41.481000"

updated_date

string | null

When the record last changed, as a UTC timestamp in ISO 8601 format. A record Base44 has just created carries a Z suffix, and a record read back from storage does not.

Example:

"2026-06-04T14:07:02.115000"

created_by

string | null

Email of the app user who created the record, or anonymous when a visitor created it on an app that needs no login. Apps that hide record authorship leave this field out of the response.

Example:

"jane@acme.com"

created_by_id

string | null

ID of the app user who created the record, or anonymous when a visitor created it on an app that needs no login.

Example:

"6874b0c2e1a94d0031bb77de"

is_sample

boolean | null

Whether Base44 stored the record as sample data while the app was being built. A record you create reports false.

Example:

false
