I am trying to: retrieve data via WP API from a page that uses a repeatable field group

Link to a page where the issue can be seen: N/A private development environment

I expected to see: JSON output similar to your documentation (https://toolset.com/documentation/programmer-reference/toolset-integration-with-the-rest-api/#formatted-output-for-single-and-repeatable-fields).

For example:

"toolset-meta": {
"hero-banner-repeating-component": {
"type": "field_type_slug",
"raw": [
"a",
"b",
"c"
],
"repeatable": [
{
"raw": "a",
"formatted_value": "a_formatted"
},
{
"raw": "b",
"formatted_value": "b_formatted"
},
{
"raw": "c",
"formatted_value": "c_formatted"
}
]
}
}

Instead, I got: An empty JSON array element. For example:

...
"toolset-meta": {
"hero-banner-repeating-component": []
},

...

Hello. Thank you for contacting the Toolset support.

Repeatable field groups are actually managed as hidden custom post type under the hood and establish hidden one-to-many relationship to the parent post type.

- Parent post where repeating field group is displayed (parent) can have many items of repeating field group (child).

Toolset does not offer a built-in way to publish relationships through REST API. You will need to extend the WordPress API and query the data using the relationship API.

- https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/

Maybe following related ticket will help you to understand how it should work:
