      <description>&lt;P&gt;I am trying to add property groups to a file with&amp;nbsp;&lt;/P&gt;
&lt;PRE&gt;https://content.dropboxapi.com/2/files/upload&lt;/PRE&gt;
&lt;P&gt;and I am getting an error "&lt;SPAN&gt;HTTP header "Dropbox-API-Arg": property_groups: expected list, got string". How is my property groups a string? What am I doing wrong?&lt;BR /&gt;&lt;BR /&gt;&lt;/SPAN&gt;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;

      <description>&lt;P&gt;Hi &lt;a href="https://www.dropboxforum.com/t5/user/viewprofilepage/user-id/1743908"&gt;@toki4004&lt;/a&gt;,&lt;/P&gt;&lt;P&gt;It's a good idea to prototype API call when you are not sure about something. &lt;img class="lia-deferred-image lia-image-emoji" src="https://www.dropboxforum.com/html/@41457EF40051AFF130FDBFE21B496926/emoticons/1f609.png" alt=":winking_face:" title=":winking_face:" /&gt; So you can easy find out all differences and what's wrong. In particular (for &lt;A title="Create a new file with the contents provided in the request" href="https://www.dropbox.com/developers/documentation/http/documentation#files-upload" target="_blank" rel="noopener"&gt;/2/files/upload&lt;/A&gt;) you can take a look &lt;A title="Dropbox API Explorer • upload" href="https://dropbox.github.io/dropbox-api-v2-explorer/#files_upload" target="_blank" rel="noopener"&gt;here&lt;/A&gt;. Click on "Show Code" to see how the call look like. Most valuable for you may be the "HTTP request" form of view (PHP is not supported).&lt;/P&gt;&lt;P&gt;Good luck.&lt;/P&gt;</description>

      <description>&lt;P&gt;&lt;a href="https://www.dropboxforum.com/t5/user/viewprofilepage/user-id/1743908"&gt;@toki4004&lt;/a&gt; As Здравко linked to, the API v2 Explorer is a good tool for prototyping and inspecting how API calls should be formatted.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;I see in your code you're using json_encode on the property_groups value directly. The value is supposed to be a list, but note that json_encode itself returns a string, you're actually sending that parameter value as a string instead of the expected list. It looks like you could do so by removing that first json_encode call and just supplying the $meta variable itself.&lt;/P&gt;</description>

      <description>&lt;P&gt;Thanks, I am a newbie, wondering if you could help:&lt;/P&gt;&lt;P&gt;From the explorer page, I get this error&lt;/P&gt;&lt;PRE&gt;&lt;SPAN&gt;... "Dropbox-API-Arg": property_groups.template_id: '' must be at least 1 characters, got 0&lt;/SPAN&gt;&lt;/PRE&gt;&lt;P&gt;Is the template required? All I am trying to do is save a custom metadata snippet with the file.&lt;BR /&gt;&lt;BR /&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;I tried&amp;nbsp;&lt;SPAN&gt;removing that first json_encode call and just supplying the $meta variable. Now I get the error:&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;SPAN&gt;"... property_groups: expected list, got builtins.dict"&lt;/SPAN&gt;&lt;/P&gt;&lt;P&gt;&lt;a href="https://www.dropboxforum.com/t5/user/viewprofilepage/user-id/10"&gt;@Greg-DB&lt;/a&gt;&lt;/P&gt;</description>

Yes, property group is list/array. The elements of this list are dicts. The fields of each element is list also.&lt;/P&gt;&lt;P&gt;Take a bit more care. 🙋&lt;/P&gt;</description>

      <description>&lt;P&gt;&lt;a href="https://www.dropboxforum.com/t5/user/viewprofilepage/user-id/1743908"&gt;@toki4004&lt;/a&gt; The 'property_groups' parameter on the /2/files/upload endpoint is optional. (You can find that in the documentation for&amp;nbsp;&lt;A href="https://www.dropbox.com/developers/documentation/http/documentation#files-upload" target="_blank"&gt;/2/files/upload&lt;/A&gt;.) You should only set it if you are using the "file properties" feature. If you do set the 'property_groups' parameter though, the 'template_id' field in any given PropertyGroup object is required and must not be empty.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;You can find information on the file properties feature, such as what templates are and how to work with them, in &lt;A href="https://www.dropbox.com/developers/documentation/http/documentation#file_properties" target="_blank"&gt;the documentation for it here&lt;/A&gt;.&lt;/P&gt;</description>

      <description>&lt;P&gt;Where before I was getting en error&lt;/P&gt;&lt;LI-CODE lang="php"&gt;property_groups: expected list, got string&lt;/LI-CODE&gt;&lt;P&gt;now with this change:&lt;/P&gt;&lt;LI-CODE lang="php"&gt;	$meta = array(
		array("cat", "dog")
    );
	

    $fields = array(
        "path" =&amp;gt; "/ba.txt",
        "autorename" =&amp;gt; false,
        "mode" =&amp;gt; "overwrite",
        "mute" =&amp;gt; false,
        "strict_conflict" =&amp;gt; false,
        "property_groups" =&amp;gt; $meta
    );&lt;/LI-CODE&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I am getting:&amp;nbsp;&lt;/P&gt;&lt;LI-CODE lang="php"&gt;property_groups: expected object, got list&lt;/LI-CODE&gt;&lt;P&gt;&lt;BR /&gt;So now it's NOT expecting a list...? I am confused on the format that it wants to receive.&lt;/P&gt;</description>

      <description>&lt;P&gt;&lt;a href="https://www.dropboxforum.com/t5/user/viewprofilepage/user-id/10"&gt;@Greg-DB&lt;/a&gt;&amp;nbsp;Ah, ok, so the template is required. I guess I'll have to set that.&lt;/P&gt;&lt;P&gt;My end goal is to assign a custom meta data to a file/folder. It sounds like I'll need to set template and then deal with that property.&lt;/P&gt;</description>

      <description>&lt;P&gt;Also don't nest lists one in other directly..&lt;/P&gt;</description>

      <description>&lt;P&gt;&lt;a href="https://www.dropboxforum.com/t5/user/viewprofilepage/user-id/1743908"&gt;@toki4004&lt;/a&gt; The "property_groups: expected object, got list" error is referring to the items in the property_groups list; the items are supposed to be objects of type PropertyGroup, but you're instead supplying a list via `array("cat", "dog")`.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;It should look more like this:&lt;/P&gt;
&lt;LI-CODE lang="php"&gt;    $meta = array(
        array("template_id" =&amp;gt; "ptid:TEMPLATEID", "fields" =&amp;gt; array(array("name" =&amp;gt; "FIELDNAME", "value" =&amp;gt; "FIELDVALUE")))
    );&lt;/LI-CODE&gt;
&lt;P&gt;You'd need to replace the CAPITALIZED values with your actual values of course.&lt;/P&gt;</description>

      <description>&lt;P&gt;I created a template in my app and got a response with a template id. I can also make a call in my app "get_for_user" and view the schema for the new template. BUT when I go to your API explorer, I get nothing back&lt;BR /&gt;&lt;STRONG&gt;templates/list_for_user&lt;/STRONG&gt;:&lt;/P&gt;&lt;PRE&gt;"template_ids": []&lt;/PRE&gt;&lt;P&gt;&amp;nbsp;Also, &lt;STRONG&gt;get_for_user&lt;/STRONG&gt;:&lt;/P&gt;&lt;PRE&gt;{
  "error_summary": "restricted_content/..",
  "error": {
    ".tag": "restricted_content"
  }
}&lt;/PRE&gt;&lt;P&gt;Why am I able to get_for_user via my app but not the explorer?&lt;/P&gt;&lt;P&gt;Also, can you please explain: does the add_template needs to be called only once and then it's stored? If yes, until you delete it?&lt;/P&gt;</description>

Every template is valid for application-user pair (neither for user alone nor application itself). You had created your template in one application (your application) and tried access it in another one (API explorer). &lt;img class="lia-deferred-image lia-image-emoji" src="https://www.dropboxforum.com/html/@41457EF40051AFF130FDBFE21B496926/emoticons/1f609.png" alt=":winking_face:" title=":winking_face:" /&gt;&lt;/P&gt;&lt;P&gt;Hope this clarifies matter.&lt;/P&gt;</description>

&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;And yes, you only need to create the template once per app-user, after which it's recorded on the Dropbox servers so you can use it for that app-user without creating it every time.&lt;/P&gt;</description>

      <description>&lt;P&gt;I've been struggling getting my properties to show. I created a template fine, assigned a property to an item, and now I want to view a folder list with items + see their properties. I get this error:&amp;nbsp;&lt;/P&gt;&lt;UL&gt;"Error in call to API function "files/list_folder": request body: include_property_groups.filter_some: expected list, got string".&lt;/UL&gt;&lt;UL&gt;Here is my code below. What format is expecting for "include_property_group"?&lt;/UL&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;LI-CODE lang="php"&gt;    $meta = array(
        ".tag" =&amp;gt; "filter_some",
        "filter_some" =&amp;gt; "ptid:-ynhqttM3GkAAAAAAAAeOg"
    );


    $fields = array(
        "path" =&amp;gt; "/folder 2",
        "include_property_groups" =&amp;gt; $meta,
        "recursive" =&amp;gt; false,
        "include_media_info" =&amp;gt; false,
        "include_deleted" =&amp;gt; false,
        "include_has_explicit_shared_members" =&amp;gt; false,
        "include_mounted_folders" =&amp;gt; false
    );

    $headers = array(
        'Authorization: Bearer ' . $auth_token,
        'Content-Type: application/json'
    );

    $ch = curl_init();
    curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );
    curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
    curl_setopt( $ch, CURLOPT_CUSTOMREQUEST, "POST" );
    curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers );
    curl_setopt( $ch, CURLOPT_URL, 'https://api.dropboxapi.com/2/files/list_folder' );&lt;/LI-CODE&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

I get this error:&amp;nbsp;&lt;/P&gt;&lt;UL&gt;"Error in call to API function "files/list_folder": request body: include_property_groups.filter_some: expected list, got string".&lt;/UL&gt;&lt;UL&gt;Here is my code below. What format is expecting for "include_property_group"?&lt;/UL&gt;&lt;P&gt;...&lt;/P&gt;&lt;HR /&gt;&lt;/BLOCKQUOTE&gt;&lt;P&gt;Even when you have one property group it should be a list with one entry, not just a single string, as you have passed. If you take a look on 'filter_some', you will see that expected type is list, not something else (list of ids, not just one id itself - even when it's alone). Wrap your id' string with array.&lt;/P&gt;</description>
