How to send a text message with link preview?

[david-botelho-mariano]

Does anyone have sample code to send text message with preview link?

[david-botelho-mariano]

//load a file as bytes
thumb, err := ioutil.ReadFile("thumb.jpg")
if err != nil {
	log.Errorf("Failed to load thumb: %v", err)
	return
}		

// construct the message
content := &waProto.Message{
	ExtendedTextMessage: &waProto.ExtendedTextMessage{
		Text:          proto.String("Teste123\n\nhttps://litoranea.fm/?p=21445"),
		Title:         proto.String("Entidades debatem formas de combater o uso do Pix em casos de sequestros relâmpagos - Grupo Litorânea de Comunicação"),
		CanonicalUrl:  proto.String("https://litoranea.fm/entidades-debatem-formas-de-combater-o-uso-do-pix-em-casos-de-sequestros-relampagos"),
		MatchedText:   proto.String("https://litoranea.fm/?p=21445"),
		JpegThumbnail: thumb,
		Description:   proto.String("O Centro de Apoio Operacional Criminal (CAOCrim) do Ministério Público do Estado de São Paulo (MPSP) e promotores de Justiça com atuação na esfera criminal reuniram-se nesta sexta-feira (3), na capital paulista, com representantes da Federação Brasileira de Bancos (Febraban) para discutir formas de combater o uso do Pix como pagamento por resgates em sequestros …"),
	},
}

// parse the JID
recipient, ok := parseJID("[email protected]")
if !ok {
	return
}

// send the message
resp, err := cli.SendMessage(context.Background(), recipient, content)
if err != nil {
	log.Errorf("Error sending message: %v", err)
} else {
	log.Infof("Message sent (server timestamp: %s)", resp.Timestamp)
}

Thanks but it did not work for me. Are you positive that the code works? I've tried 'as is' and then adding ThumbnailDirectPath: &resp.DirectPath, ThumbnailSha256: resp.FileSHA256, ThumbnailEncSha256: resp.FileEncSHA256, MediaKey: resp.MediaKey,

All unsuccessful.

I'm sure my code worked because I'm using it in a production environment.

Remember to put the correct link in a similar way to the example and also the "MatchedText" must be inside the "Text" of the "ExtendedTextMessage".

If nothing works, try using my code without any changes so you can see that it works.

Thanks a lot!!!! Your hint did the trick. I was not having the matchedText into the Text !!!!
