Double opt in doesn't work - Redirection issues

[itsdun]

Hi sendinblue Team,

the double opt in feature is not working for me. The email is sent correctly to the given email address, but when i click the confirmation-button inside mail, i get a blank page and a error in chrome console: Uncaught DOMException: Failed to set the 'href' property on 'Location': 'http://' is not a valid URL.
at HTMLIFrameElement.onload

I've played around with different redirectionUrls and also without this parameter, no success.

Code:

$apiInstance = new \SendinBlue\Client\Api\ContactsApi(
    new \GuzzleHttp\Client(),
    $config
);
$createDoiContact = new \SendinBlue\Client\Model\CreateDoiContact(
    [
        'email' => 'mail@example.com',
        'redirectionUrl' => '<url>',
        'includeListIds' => [2],
        'templateId' => 2,
    ]
);
try {
    $apiInstance->createDoiContact($createDoiContact);
} catch (\Exception $e) {
    echo $e->getMessage(), PHP_EOL;
}

Regards,
Marco

Similar issue here. Clicking the link in the button in the email registers the click on the dashboard but I immediately get redirected to a page that doesn't exist and the contact never gets added to the list.

Hello,

Pinging @jamalofski @shubhamUpadhyayInBlue @ekta-slit @rajatsib

I have the same issue:

• After createDoiContact I receive the email with the confirmation link.
• Clicking on the button in the email opens the browser showing

cijegjf.r.af.d.sendibt2.com sent an invalid response.
ERR_INVALID_REDIRECT

• In my sendinblue account, the contact is NOT created and NOT added to the desired list.

This feature is very important and urgent to me.

Please. Can we get a weight on this issue or, at least, have some feedback? The issue occurs even while using the Curl example, from your own API reference... This definitely needs more attention.

I opened a ticket in the sendinblue application and got the following answer, which worked for me:

• send a request with redirectionUrl (otherwise it still does not work)
• set the doi link in your template to {{ params.DOIurl }}

Hi @itsdun ,
Please use the variable {{ params.DOIurl }} in your template as mentioned here.
https://developers.sendinblue.com/reference#createdoicontact

@skynetsib Where do we have to use {{ params.DOIurl }} exactly ?
Here in the point 4.3.a it's mentioned that {{ doubleoptin }} must be used, I can confirm that I am not even able to select the Default Double optin template in the sendinblue wordpress plugin when {{ doubleoptin }} is not present in the template..

Hi @kevinley

First to create a DOI template

You will need to add an 'optin' tag in the template setup.
You will also need to specify which CTA in your template design follows to the actual confirmation, for this you need to setup the {{ doubleoptin }} placeholder in your CTA link or button.

To create a contact through DOI flow

You will need to replace the {{ doubleoptin }} with {{ params.DOIurl }} in your DOI template design in case you want to specify a custom redirection URL once your contact clicks the CTA. DOIurl is passed as an attribute in the API call and then embedded to the {{params.DOIurl}} placeholder.
