Hello. Thank you for contacting the Toolset support.
The REST API feature is not completely implemented yet but our developer has build 'Toolset REST', You can find it here:
=> hidden link
Please note that it's a basic Toolset REST API where a bunch of endpoints for:
- Types (fileds, CPTs, Taxonomies);
- Views (Views, Content Templates, VIews Archives);
- CRED (Forms, User Forms and their submission);
- Layouts (fetch Layouts and single layout data).
Most of the functionalities do not require the WP REST API plugin to work, but to have Types full features the plugin is needed. This work wasn't merged in the master branch yet, but as soon as it will be tested and especially documented appropriately it will.
We are working on this feature and we will add this feature to our plugins as soon as possible.
