Hi @EdgarBadilloCruz,

Error Code 131000: “Something went wrong” typically indicates an internal server error at Facebook’s end. Could you please share a short screen recording showing the entire process of adding the phone number to Pabbly Chatflow, and highlight the exact step at which you encounter the issue?

Thank you for sharing the video—the connection process looks correct.

Have you previously connected this number to a BSP or to a different Pabbly Chatflow account?

Community consensus on the Meta Developer Forum indicates that Error 131000 is often tied to a bugged App ID.

• The Fix: Create a new App in your Meta for Developers dashboard.
• Select the "Business" type and re-add the WhatsApp product.
• Reconnect this new App to Pabbly Chatflow and see if that fixes your issue.
