Title: REST API Update field Last modified: August 30, 2023 --- # REST API Update field * Resolved [Julian Holzmayer](https://wordpress.org/support/users/julholdroid/) * (@julholdroid) * [2 years, 9 months ago](https://wordpress.org/support/topic/rest-api-update-field/) * Hello guys, I have a question according to the REST API for updating a cmb2 field value. * This is the code for the registration of he field and the box: * ```wp-block-code $cmb = new_cmb2_box( array( 'id' => 'hd-object-viewer-mb', 'title' => __( '3D View Scene', 'hd-3d-viewer' ), 'object_types' => array( 'hd-object-viewer' ), 'context' => 'normal', 'priority' => 'high', 'show_names' => true, 'show_in_rest' => true ) ); $cmb->add_field( array( 'name' => 'Test Text Area', 'desc' => 'This is the json data', 'id' => 'hd-object-viewer-mb-scene-json', 'type' => 'textarea', 'sanitization_cb' => false, 'escape_cb' => false, ) ); ``` * I registerd my CPT like this: * ```wp-block-code register_post_type( 'hd-object-viewer', array( 'label' => __( '3D View', 'hd-3d-viewer' ), 'description' => 'Recipe custom post type.', 'public' => true, 'exclude_from_search' => true, 'show_in_rest' => true, 'supports' => array( 'title' ), 'menu_icon' => 'dashicons-admin-site', ) ); ``` * I now want to update the field via the REST API. When i make a GET Request to/ wp-json/cmb2/v1/boxes/hd-object-viewer-mb/fields/hd-object-viewer-mb-scene-json i get the field back (so the field is registered in the API) But when i do a POST request to the same URL i get an error: * ```wp-block-code { "code": "cmb2_rest_no_field_by_id_error", "message": "No field found by that id.", "data": { "status": 403 } } ``` * My POST body is: * ```wp-block-code { "object_id": 49, "value": "other value test", "object_type": "post" } ``` * I also tried it with the “`hd-object-viewer`” (CPT) object_type which results in the same error. * What is the object_id anyways. I considered it as the post id, maybe this is not correct. * For Authentication i used a Application password with my admin User, so i am pretty sure i am authenticated at it would say otherwise. Maybe i don’t have the permission to change the metafield, which would be weird as this is the application password for the admin user. * Any help would be appreciated. * Thanks in Advance.

It covers these routes and what the object_type is. If you still run into issues, let us know.

Try following the recommendation in the docs with the query args. * Thread Starter [Julian Holzmayer](https://wordpress.org/support/users/julholdroid/) * (@julholdroid) * [2 years, 9 months ago](https://wordpress.org/support/topic/rest-api-update-field/#post-17012649) * Thanks you for your reply. * Unfortunately i still get the same error, making a POST Request without any body to this route: /wp-json/cmb2/v1/boxes/hd-object-viewer-mb/fields/hd-object-viewer- mb-scene-json?object_id=49&value=other&object_type=postI use Postman to make the request and the id of the post where i want to change the metafield is 49. * For Authtentication i created a application password for the admin user and passed it with Basic Auth like mentioned [here](https://developer.wordpress.org/rest-api/using-the-rest-api/authentication/#basic-authentication-with-application-passwords) in the request * Ah and by the way i use: - WP: 6.3.1 - CMB2 installed via composer inside my own plugin: “cmb2/cmb2”: “^2.10” * - This reply was modified 2 years, 9 months ago by [Julian Holzmayer](https://wordpress.org/support/users/julholdroid/). - This reply was modified 2 years, 9 months ago by [Julian Holzmayer](https://wordpress.org/support/users/julholdroid/). - This reply was modified 2 years, 9 months ago by [Julian Holzmayer](https://wordpress.org/support/users/julholdroid/). * Plugin Author [Justin Sternberg](https://wordpress.org/support/users/jtsternberg/) * (@jtsternberg) * [2 years, 9 months ago](https://wordpress.org/support/topic/rest-api-update-field/#post-17016713) * When testing this in my API app, Insomnia, I was seeing this same behavior (the POST request not updating the field). It turned out it was because I was using the wrong url (in my case `http` instead of `https` and the server was doing a redirect and changing to a `GET`). See screenshot here: [https://a.supportally.com/i/hBDQ9a](https://a.supportally.com/i/hBDQ9a) Check to see if you’re experiencing the same. * You could also add some logging to your server to see what the request method is when it lands there. E.g. `error_log( '$_SERVER[REQUEST_METHOD]: ' . print_r( $_SERVER['REQUEST_METHOD'], true ) );` * Thread Starter [Julian Holzmayer](https://wordpress.org/support/users/julholdroid/) * (@julholdroid) * [2 years, 9 months ago](https://wordpress.org/support/topic/rest-api-update-field/#post-17016860) * Hello Justin, this did’t solve my problem (there was no redirect at my request happening. So the method allways was POST). * As my plugin’s use case changed I don’t need the REST API anymore. * But thank you anyway for looking into the problem.
