Pipedrive powerup integration - Authorization failed

[Jordi Hortal i Reballí]

Hi everyone,

I am currently stuck in an endless loop trying to authorize the official Pipedrive Power-Up in my Trello workspace, and I cannot get past the error screen.

When I click "Link Pipedrive Account" on my Trello board, the authorization pop-up opens correctly. It asks for permission to connect to my Pipedrive company account. However, when I click "Continue to the App" (or authorize), the pop-up closes and Trello throws the following error:

"Authorization failed. Something went wrong. Please try again."

Meanwhile, if I try to trigger the installation from the Pipedrive Marketplace side, it tells me "App already installed", but Trello remains completely disconnected and the Pipedrive icon stays greyed out.

What I have already tried (without success):

• Browser & Cache: Tried both normal mode and Incognito/Private windows. Completely cleared cache and site data specifically for Trello and Pipedrive

• Extensions & AdBlockers: Disabled all ad-blockers and privacy shields

• Third-Party Cookies: Explicitly allowed third-party cookies in Chrome settings

• Clean Slate (Revoking Access): Went to Trello's Settings > Connected Apps and revoked Pipedrive. Went to Pipedrive's Marketplace/Installed Apps and uninstalled Trello. Restarted the process from zero. The error persists

• Permissions: I am the Workspace Admin in Trello and hold Admin rights in Pipedrive

• Identity Sync: I am using the exact same email address and login method for both platforms to avoid OAuth mismatch

It feels like a broken token or a backend desync between Atlassian and Pipedrive. Has anyone experienced this specific roadblock recently, or is there a hidden permission I might be missing?

Thanks in advance for your help!

Thank you so much @Germán Morales!

Changing browser was the key. 

Have a nice day ;)

Hi @Jordi Hortal i Reballí , incognito is still the same browser engine, so it doesn't count as the fix Trello documents for a Power-Up that won't authorize: try it from a genuinely different browser, Firefox or Edge instead of another Chrome window, since once it authorizes there it works everywhere while you're logged into the same account.

Also worth checking, the revoke you did was through the board's Connected Apps, not the account's token list. Go to trello.com/my/account, Applications section, and revoke Pipedrive from there specifically before reconnecting.

If it still breaks after both, the failure is most likely on Pipedrive's side of the OAuth handshake rather than Trello's, so a parallel ticket with Pipedrive support makes sense.
