Document Service API: Selecting fields

By default the Document Service API returns all the fields of a document but does not populate any fields. This page describes how to use the fields parameter to return only specific fields with the query results.

💡 Tip

You can also use the populate parameter to populate relations, media fields, components, or dynamic zones (see the populate parameter documentation).

✏️ Note

Though it's recommended to target entries by their documentId in Strapi 5, entries might still have an id field, and you will see it in the returned response. This should ease your transition from Strapi 4. Please refer to the breaking change entry for more details.
