# Sendinblue API key v3?

 * I have been following [this tutorial](https://www.wpbeginner.com/wp-tutorials/how-to-fix-wordpress-not-sending-email-issue/)
   to the letter. Helpfully, I am using both Sendinblue and my host is Bluehost,
   so the entire tutorial is applicable to me.
 * However, I am getting this error log when sending a test email:
 *     ```
       Versions:
       WordPress: 5.8
       WordPress MS: No
       PHP: 7.4.22
       WP Mail SMTP: 3.0.3
   
       Params:
       Mailer: sendinblue
       Constants: No
       API Key: Yes
   
       Debug:
       Email Source: WP Mail SMTP
       Mailer: Sendinblue
       [unauthorized]: Key not found
       ```
   
 * I have authorised my domain and all three records have validated.
 * I did, however find it strange that the API key that Sendinblue provides me begins
   with a bunch of asterisks… It’s like it is hiding the real key from me. Is it
   because I have a free version of Sendinblue?

 * Hi [@chubacca](https://wordpress.org/support/users/chubacca/),
 * Thanks for reaching out. Asterisks are the masks and not the actual characters
   in the API key. The API key will only be shown once while creating. Please [create a new API key](https://account.sendinblue.com/advanced/api)
   and remember them or copy in the safe place.
 * I hope this helps!

 * Hi Sanjeev,
 * I thought that was the case (re: masks), but I just can’t figure out how to view
   any API keys without the asterisks.
 * The one that I see was already on the API Keys page with these details: **Info:**
   API v3 and **Name:** N°3.
 * I have created a new API key, on the same page as your link, I have named it “
   WordPress” but the API key that is generated is still full of asterisks.

 * Hi,
    I’ve been using WP SMTP and linked to SendInBlue for months now, without
   issues.
 * I’ve now had the same error as the lady above – ever since I installed the actual
   SendInBlue plugin.
 * The WP SMTP test email still actually works – BUT I don’t get the email from 
   the visitor/sender email send from my website to my inbox.
 * Have been in contact with SendInBlue, and they can’t seem to find out why, as
   the SMTP settings are coming from the WP SMTP side, not the SendInBlue side.
 * Have validated senders emails, and have validated TXT, STP, DKIM settings coming
   from my Cloudflare panel are working.
 * Prior to this WP SMTP didn’t show the::
    Email Source: WP Mail SMTP Mailer: Sendinblue[
   unauthorized]: Key not found
 * I have tried a couple of times to delete and get a new key.
    But the error just
   won’t go away, and I don’t get the email.
 * Any ideas?

 * Hi there,
 * The Sendinblue API key now only appears at the time of creation like [this screenshot](https://d.pr/ouBUkL).
   If you’re not seeing this or have other issues with the API key, please contact
   the Sendinblue team. They can check into your account with any issues.
 * I hope this helps!
