As part of the effort to streamline the execution of API requests, the available filters usable in API v3 GET /tickets requests have been narrowed down. From version 5.51.5.29 onwards, only those filters available in the panel can be used in API requests to retrieve lists of tickets. Requests that use non-supported filters will either return an error response or ignore the filter and return results as if the filter was not applied.
Required action
If you are utilizing API v3 to retrieve lists of tickets with the _filters parameter in your requests, it is recommended to review all your sources that use our API according to our new article about filtering GET /tickets API v3 results, to ensure you are using the supported filters.
Another way to identify the available filters is to apply the desired filter directly in the panel and inspect the payload of the request using your browser's developer tools.
If you would like to consult your API with our support team, you are welcome to send us an email with explanation and example of your API to support@liveagent.com.
