BDP Connector ✨ New and recommended

⭐ Recommended method for connecting BDP to haddock

haddock Connector is a small program that is installed on your restaurant computer and automatically sends sales from BDP to haddock. Once configured, it runs by itself and you do not have to do anything else.

What do I need before starting?

• The computer where BDP is installed must be turned on and running BDP.
• You need access to that computer to install the program. If you are not physically at the venue, you can ask someone there to give you remote access with AnyDesk or TeamViewer - these are free programs that let you see and control the computer from another location.
• Have the BDP username and password and the export profile number handy (if you do not have them, ask your BDP reseller or technician), as well as the haddock authentication code (you will find it in the haddock web app, under Restaurant settings > My integrations > BDP Connector).

💡 Tip: If you do not have all the details or do not feel confident doing the installation, the easiest option is to send everything to your BDP reseller or technician. Share the PDF guide and the haddock authentication code with them - they will be able to do the installation and setup remotely without you having to handle anything technical.

Step 1 - Download and install

1. On the computer where BDP is installed, download the haddock Connector installer.
2. Open the downloaded file. If Windows asks for permission (Windows protection screen), click "More info" and then "Run anyway".

   
   

   
   

   
   

   
   
3. Follow the installer steps:
4. • Welcome screen:

• Select the destination folder:

• Make sure the "Create a desktop shortcut" option is checked.

• Review the summary and click "Install".

4. When installation finishes, make sure "Launch haddock Connector" is checked and click "Finish". The program will open automatically.

   
   

   
   

Step 2 - Configuration

When the program opens, you will see a screen with several fields to fill in:

1. POS System:
Select BDP from the drop-down menu.

2. BDP connection details:

• Login: The user name BDP uses for the connection. Ask your BDP reseller or technician for it (for example haddock_api).
• Password: The password for that user (for example ********).
• Export Profile Number: A number that indicates which data BDP exports. Your BDP reseller or technician will provide it (for example 123).
• Advanced settings: Expanding this option lets you configure the port (default 5555) and other additional settings.

3. haddock Authentication:

• Authentication Code: Go to the haddock web app, open Restaurant settings > My integrations > BDP Connector, and copy the 10-digit code shown there (for example G2807V6VJY). Paste it into this field.

4. Sync Settings & Dates:

• Sync interval: How often sales will be sent to haddock, in minutes. You can leave the default value (30 minutes).
• Sync Dates (Start / End): The period from which you want to import sales history. By default, it retrieves the last year of history.

Step 3 - Connect

Click the blue "Connect" button. The program runs a series of checks and shows them as a list of items that turn green one by one:

1. POS reachable — the connector finds BDP on this computer (or at the BDP server IP you entered).
2. POS credentials valid — BDP accepts the username and password.
3. API license active — BDP's integration module is enabled.
4. haddock cloud — there is a connection to haddock's servers.
5. haddock auth code valid — your authentication code is correct.

When all of them are green, the connection is ready and sales will start syncing. If an item turns red, that is the source of the problem: look up the message the connector shows in the Errors and solutions section below.

How do I know it is working?

Once connected, you will see the status panel with real-time information: when the last sales sync happened, how many syncs have been completed, and a log of recent activity. If you want to sync right away without waiting, press "Sync Now".

Day-to-day use

• The program runs in the background - you do not need to keep it open. When you close the window, it minimizes to the notification area (bottom right of the Windows desktop) and keeps working.
• To open it again, click the icon in the notification area.
• It updates and restarts itself if there is any problem - you do not need to worry about anything.

🔧 Errors and solutions

If a check turns red when connecting, the connector shows a message. Look it up here to see what to do:

🚨 "API not accessible on localhost:5555. Make sure BDP is running on this machine."

(Check 1 — POS reachable)

✅ BDP is not open, is on another computer, the port is wrong, or a firewall/antivirus is blocking the port. Check that:

• BDP is open and running on the correct computer.
• The port under Advanced settings is 5555 (the default). If BDP runs on another machine, enter its server IP in the configuration.
• If opening http://localhost:5555 in the browser on that machine loads nothing, BDP's API is not listening there: contact your BDP reseller.

🚨 "BDP server is reachable but login failed."

(Check 2 — Credentials)

✅ The username or password is wrong. Verify them with your BDP reseller or technician.

🚨 "BDP license is not activated or login credentials are invalid."

(Check 3 — API license)

✅ BDP's integration module is not enabled. Ask your BDP reseller to enable it and to confirm your username, password, and export profile number.

🚨 "Cannot reach haddock cloud."

(Check 4 — haddock cloud)

✅ The computer has no internet access, or a firewall/proxy/antivirus is blocking the secure (HTTPS) connection to haddock. Check the computer's internet connection and that the firewall or antivirus allows outbound HTTPS traffic to haddock. If the message says the cloud "is reachable but rejected the request", it is a temporary issue: try again in a few minutes.

🚨 "Authentication code is invalid" / "Invalid authentication code format."

(Check 5 — haddock auth code)

✅ The code was copied incorrectly or has expired. Go to the haddock web app (Restaurant settings > My integrations > BDP Connector), generate a new one, and paste it in full. Codes expire if they are not used.

🚨 I do not have the username, password, or export profile number

✅ Ask your BDP reseller or technician for them. They manage this data and must provide it to you.

The connector was working and now it fails

• I do not see sales right after connecting: the first sync can take a while if there is a lot of history. Press "Sync Now" in the status panel to force it.
• If you see the "Sync has been failing — please check your configuration" notice with a Reconfigure button, press it and use the list above to see which check is red.
• The connector also shows notifications in the Windows notification area (bottom right) when it has been unable to reach the POS or haddock for a while.
• Check that the POS computer is powered on and that BDP is still running.

Still not working after checking this? See How to fix connection problems with my POS or contact haddock support chat.

My articles look wrong or are missing in haddock

The connector pushes both sales and the article catalog automatically (catalog every ~15 minutes by default). If the catalog still looks broken — wrong names, missing modifiers/combos, or "BARCELO & COCA COLA | BARCELO & KAS LIMON | …" style accumulated names on a single article — you can force an immediate refresh from the haddock web app:

1. Go to Restaurant settings > My integrations > BDP Connector.
2. Click "Refresh".

This queues both an orders resync and a catalog resync that the connector will pick up on its next heartbeat (typically within a minute). The button is rate-limited to once every 24 h per integration.

If after the refresh the catalog still looks wrong, contact support — the issue is on the connector / BDP side and needs investigation.

Integrations may include additional costs not covered by haddock.
