Fetch static content

Retrieves the default content of a slot without applying audience targeting, experience evaluation, or experiment assignment. Use it for server-side rendering (SSR) or cache-friendly responses where personalization context is not available.

This is the server-side variant, intended for calls originating from your backend. It authenticates with an API key and applies rate limits tuned for backend traffic. For browser-accessible static content, use the client-side variant instead.

Example

Here is an example of how to fetch static content from a backend:

const response = await fetch('https://api.croct.io/external/web/static-content', {  method: 'POST',  headers: {    'Content-Type': 'application/json',    'X-Api-Key': '<API KEY>',  },  body: JSON.stringify({    slotId: 'home-hero',    version: '1',    preferredLocale: 'en-us',    includeSchema: true,  }),});
const {content, metadata} = await response.json();

Request headers

This endpoint accepts the following HTTP headers:

Content-Type

string

Must be application/json.

X-Api-Key

string

The API key to use for server-side requests.

Keep your API key safe

Never use your API key in client-side code, only in server-side environments.

X-Client-Library(optional)

string

The SDK name and version, such as Croct SDK JS v0.20.0.

Used for usage statistics and feature switching to preserve backward compatibility across SDK versions.

Parameters

This endpoint accepts the following JSON body parameters:

slotId

string

The ID of the slot to fetch, such as hero-banner.

version(optional)

string

The schema version of the slot to fetch, in major or major.minor format, such as 1 or 1.2.

Defaults to the latest version when omitted.

preferredLocale(optional)

string|null

The locale code of the content to fetch.

The code consists of a two-part string that specifies the language and, optionally, the country. For example, en represents English, en-us stands for English (United States), and pt-br for Portuguese (Brazil). It is case-insensitive and supports both hyphens and underscores as separators to accommodate the different conventions used by browsers, libraries, and other systems.

Falls back to the slot's default locale when the preferred locale is unsupported or omitted. Pass null to explicitly use the default.

includeSchema(optional)

boolean

Whether to include the slot's content schema in metadata.schema.

Default:false

Response headers

X-Suspension-Reason(optional)

string

The reason the API returned an empty response.

When the workspace has suspended services, the API returns 202 Accepted with an empty body and this header. Clients should treat this as a traffic control signal, not an error, and fall back to default behavior.

The possible values are:

Value	Description
tracking_and_personalization_suspended	The workspace has suspended services.

Response

This endpoint returns a JSON response with the following properties:

content

object

The slot's default content.

The shape is defined by the slot's content schema, plus a reserved _component field.

_component

string|null

The component identifier and major version, such as hero-banner@1.

Is null when no component is associated with the slot.

metadata

object

Metadata describing the returned content.

version

string

The resolved slot schema version.

contentSource

string

Always slot for static content requests, since neither audience targeting nor experiments are applied.

schema(optional)

Schema

The slot's content schema definition.

Human-readable labels and descriptions are omitted from the returned schema for security reasons, since they may contain sensitive business information.

This property is included only when the request set includeSchema to true.
