Help in cURL, resending form

I'm having a question about the process of submitting the form with CAPTCHA , I'm trying to get data straight from DENATRAN , we understand what I did.

Get information: I've made a cUrl script along with PhantomJS to get the information from the DENATRAN page.

Process CAPTCHA : I can do the CAPTCHA code verification automation that is present in the form.

My question now is: How can I send or resend what I got from there, since there is a token in the form, can someone give me a help, I know that the form passes 6 parameters (hdnIntRC, hdnMsg, txtCPFCNPJ, txtCodRenavam, txtToken_captcha_serpro_gov_br, txtTexto_captcha_serpro_gov_br).
