To access Plex APIs, complete following steps:

Request a Plex API Developer Account

A Plex Developer Account is required to access the Developer Portal and call the API.

  1. To request developer accounts, your Plex Champion must submit a case to the Plex support Service Cloud. Include a name and email address for each account that you need created.
  2. Plex will review your request and send a confirmation email to the email account(s) that you requested.
  3. You will be notified via email when your account as been created. Follow the instructions in the email to log in to the Developer Portal.
  4. After you have successfully accessed the Developer Portal, you must create an App in the portal to get your API keys.

  1. Access the Plex Developer Portal at
  2. Click on your account name and select My Apps.
  3. Click +Add a new App.
  4. On the Add App screen, type a name for your App.
  5. For Product, select the API products to which you want access.

Call the API

If you have a Plex API developer account, you can test Plex APIs directly within the Plex Developer Portal.

  1. In the Developer Portal, go to the APIs page.
  2. Click the API operation that you would like to test.
  3. Click a resource to view its details, including the resource URL and the request body.
  4. After the Request Body, in the API Key field, click Set.
    1. ​For Name, type X-Plex-Connect-Api-Key.
    2. For Value, type your Customer Key. (You can retrieve this from the App that you created. See Obtain API credentials.)
    3. Select Header.
    4. Click Ok.
  5. Click Send this request.
  6. The API request is sent. The page will update with the response.
  7. After a successful response, you are ready to use the API. Update your case in the ServiceCloud to confirm that you were able to access the API.  

Error Codes

400 - Malformed request
400 errors generally indicate that the body of the request does not match the resource being requested. 

400 - Validation failure
One or more of the parameters use an incorrect format or are omitted from the request.

401 - Request not authenticated
A 401 error can occur when you try to access the system using an expired api key, an invalid api key, or without an api key at all.
If you receive this error, verify that the X-Plex-Connect-Api-Key header is specified on the request and that the key matches the value in the Plex Developer Portal.

404 - Resource not found
A 404 error can occur when your application attempts to access Plex functionality using an incorrect request URL or if no data exists to return.

500 - Request processing error
500 errors are unexpected. If you can reproduce the error, submit a support ticket to Plex. Include the steps to duplicate the issue, but do not include client secrets, passwords, or subscription keys.

Making API Calls

Request Headers

Subscription Key header

All Plex API requests require a valid subscription key header. The request header X-Plex-Connect-Api-Key is a subscription key which provides access to the API. You can obtain your API key through the Plex Developer Portal.
If you do not include the subscription key header in an API request, or provide an invalid subscription key, you will receive the following response:

"message":  "The request could not be authenticated."


Tenant ID header

Plex API requests are performed in the context of a single default tenant (also called an entity or PCN). The request header X-Plex-Connect-Tenant-Id can be used to execute the request for a tenant other than the default one. The header value to use must be a tenant ID.

Customer ID header

Plex API requests are performed in the context of a single default tenant (also called an entity or PCN). The request header X-Plex-Connect-Customer-Id can be used to execute the request for a different tenant other than the default one. The header value to use must be a PCN value.
If you do not have access to the requested tenant you will receive the following response:

"message":  "The request could not be authenticated."


URL Structure

Managed endpoints have the following form:

https://[tier.]{collection}/{version}/{resource} [/{resource id}]?[filters] 


List Query String Parameters

Some APIs have methods that can accept a list for a query string parameter.
To use multiple values for a list query string parameter, construct the URL with multiple instances of the query string parameter and its value pair.
For example, for a query string parameter Id that can accept a list of values, the URL for the request could look similar to this example:


In this example, three different values are provided for the Idquery string parameter, and the request will use the three parameters that are listed. 

Dates and Times

Coordinated Universal Time (UTC)

Use UTC or UTC+Offset standard data and time formats.

Format String 

Use the following format for any date or time input parameters:




YYYY       Four-digit year (required)
MM         Two-digit month (01 through 12, required)
DD         Two-digit day of month (01 through 28/29/30/31, required)
T          Constant char separator between date and time components (required)
hh         Two-digit hour (00 through 23, required)
mm         Two-digit minute (00 through 59, required)
ss         Two-digit second (00 through 59, optional)
fffffff    Fractional digits of second (0 to 7 digits, optional)
Z          Constant char designation for UTC a.k.a. "Zulu Time" (required)


The following also applies:

  • The seconds component may be excluded.
  • Fractional digits of seconds may be excluded, but when included may not exceed 7 digits. This applies to botj inputs and outputs.
  • Trailing zeros are allowed, but are not required 

The following are not supported:

  • Dates without times
  • Times without a time zone
  • Fractional digits for anything except seconds
  • Using a blank space instead of the 'T' character for date time separator
