Google recaptcha v3 always returning error - recaptcha

Question

Following the instructions I get a valid token from my front end (can see in dev tools):
window.grecaptcha
.execute(captchaPkey, { action: 'contact' })
.then((token) => {
// this is what I POST to my API
So in my React front end:
send = (event) => {
event.preventDefault()
this.setState({ busy: true })
window.grecaptcha.ready(() => {
window.grecaptcha
.execute(captchaPkey, { action: 'contact' })
.then((token) => {
// successfully get token
const payload = {
token,
name: this.state.name,
to: this.props.to,
email: this.state.email,
message: this.state.message,
}
// now I'm sending the payload to my API
// My API
update(`${api}/contact/`, {
method: 'POST',
body: JSON.stringify(payload)
}, null)
.then(data => {
this.setState({ busy: false, result: 'Email sent' });
})
.catch(error => {
this.setState({ busy: false, error: error.message });
});
})
})
}
my API controller
async function verifyCaptcha(token) {
return await axios.post('https://www.google.com/recaptcha/api/siteverify', {
secret: process.env.CAPTCHA_PKEY,
response: token
})
}
async function contact({ token, to, name, email, message }) {
const result = await verifyCaptcha(token)
if (!result || !result.data || !result.data.success) {
// always get an error here
throw new Error('Invalid captcha')
}
let targetEmail = 'default#emailaddress'
if (to !== 'admin') {
const user = await User.findOne({ username: to }, { email }).exec()
if (!user) {
throw new Error('User does not exist')
}
targetEmail = user.email
}
// rest of send
}
On my API POST endpoint sends to https://www.google.com/recaptcha/api/siteverify with the body of:
{
secret: process.env.CAPTCHA_PKEY,
response: token
}
Yet I always get "missing-input-response", "missing-input-secret" error. Is this because v3 is new? Still bugs?

Answer 1

Realised in the documentation it states "post params" not post body haha.
