Problem: The client is attempting to use a custom translation service with WPML, but it does not appear in the Translation Services list. They have set
WPML_CUSTOM_TRANSLATION_SERVICE_URL
in wp-config.php to point to their custom Translation Proxy API, which implements the WPML Translation Proxy API (JSON:API). Despite this setup, the custom service is not visible under WPML → Translation Dashboard → Translation Services. The client also noted that the “Enable other translation services” button is not visible under WPML → Support → Troubleshooting, and they do not have a Preferred Translation Service set in their wpml.org account.
Solution: We informed the client that currently, there are no plans to make custom translation services available outside of the Partner program. As alternatives, we recommended considering the following options:
Translation Hub: A centralized interface for managing translations and translators.
Automatic Translation: Built-in machine translation with flexible pay-as-you-go options.
We also mentioned that we will soon announce the PTC (Private Translation Cloud) Partnership program for Agency accounts, which will provide benefits for those accounts regarding site translations.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If further assistance is needed, please open a new support ticket.
