Tip

The invalid_format error code will be returned if you make a request to an API endpoint which includes either a route parameter or a query string parameter for format

This error code will be returned, for example, if you make an API call to retrieve a label but provide an invalid or unrecognised format, e.g.:

GET /labels/sp_00982822462453834198775303766026?format=jpeg

The supported format depends on the API endpoint, but generally includes either PDF, pdf, ZPL, or zpl.
