WhatsApp template name does not exist in the translation

I'm using the WhatsApp API to send template messages. Currently have an approved template created for the 'es' language (Spanish), but the API returns 404 every time I try to send it to a phone number.

This has gone on for weeks now and I have been unable to contact the Facebook support team.

Error information:

The error string is:

(#132001) Template name does not exist in the translation

The complete error object:

{
    "error": {
        "message": "(#132001) Template name does not exist in the translation",
        "type": "OAuthException",
        "code": 132001,
        "error_data": {
            "messaging_product": "whatsapp",
            "details": "template name (kindo_welcome) does not exist in es"
        },
        "fbtrace_id": "AukZdjNY1Ahnl_NwJXLmQZx"
    }
}

Request body:

{
    "messaging_product": "whatsapp",
    "to": "{{Recipient-Phone-Number}}",
    "type": "template",
    "template": {
        "namespace": "kindo",
        "name": "kindo_welcome",
        "language": {
            "code": "es"
        },
        "components": [
            {
                "type": "header",
                "parameters": [
                    {
                        "type": "text",
                        "text": "Juan"
                    }
                ]
            }
        ]
    }
}

I don't know if this will help anyone, but the problem for me was that I was trying to send a template that was not part of the number I was using in the WhatsApp Cloud API.

Therefore, if it did not exist in that number, it did not exist in the translation. When I used the number that the template had set, it worked.

I share the documentation about the templates so you can read more about this:
