Troubleshooting: Error while switching from view-only to a full connection in Airbnb

When upgrading an Airbnb connection from view-only to full connection, you may see an 400 HTTP after you are ready to confirm Airbnb connection to Guesty, and click Confirm on Airbnb. This article explains why this error happens and how you can resolve it.

Fix the issue

The connection flow redirects your browser through global Airbnb website (airbnb.com) to complete authorization. If you have an active session on a regional Airbnb website (such as fr.airbnb.be, airbnb.it, or airbnb.es), authorization fails and the error displays.

Option 1: Log into the correct website

To successfully upgrade to the full connection, we recommend logging in directly on airbnb.com first. Once you're logged in on airbnb.com, upgrade the specific account to the full connection again.

Step by step:

1. Open a new browser tab and go directly to airbnb.com (not your regional site).
2. Log in with your Airbnb credentials.
3. Sign in to your Guesty account.
4. In the side navigation menu, click Marketing and sales to open the dropdown menu.
5. Under Channel management, select Distribution.
6. Click Airbnb.
7. Select the read-only account you want to upgrade.
8. Click Convert to full connection.
9. Complete the upgrade as described in Pre-onboarding an Airbnb account to Guesty (view-only). 

Option 2: Manually edit the URL

Alternatively, you can edit the URL directly in the browser. Make sure you log in to your regional Airbnb website, and follow the steps:

Step by step: 

1. Sign in to your Guesty account.
2. In the side navigation menu, click Marketing and sales to open the dropdown menu.
3. Under Channel management, select Distribution.
4. Click Airbnb.
5. Select the read-only account you want to upgrade.
6. Click Convert to full connection.
7. Complete the upgrade as described in Pre-onboarding an Airbnb account to Guesty (view-only). 
8. Once the error appears, manually replace the regional domain with airbnb.com in your browser's address bar.
9. Press Enter.

If the issue persists

Browsers often redirect you automatically to localized domains, such as airbnb.fr or airbnb.es, based on your location. If the browser keeps redirecting you from airbnb.com to a regional domain, change the Airbnb display language. 

Step by step:

1. Log in to the Airbnb host account as usual.
2. On the bottom of the page, click .
3. In the "Choose language and region" section, select English (United States).
4. Click Save.

Once the Airbnb website reloads and the website address updates to airbnb.com, continue to upgrade the Airbnb connection.

Step by step:

1. Sign in to your Guesty account.
2. In the side navigation menu, click Marketing and sales to open the dropdown menu.
3. Under Channel management, select Distribution.
4. Click Airbnb.
5. Select the read-only account you want to upgrade.
6. Click Convert to full connection.
7. Complete the upgrade as described in Pre-onboarding an Airbnb account to Guesty (view-only). 

Contact support

If the issue persists, contact support, and provide the following details: 

• A screenshot of the error page.

• The Airbnb domain you're currently logged into.

• The URL shown in the browser when the error occurs.

• Confirmation that you were logged into airbnb.com before retrying the flow.
