ChatWoot Integration Configure WAHA settings with session

[mmojadad]

Hi!
I have encountered an issue at the ChatWoot => WAHA stage, specifically in the Configure WAHA settings with session section. Although no error messages or logs are displayed anywhere, I am not receiving any messages on WhatsApp.

I will explain my question with an example and would be very grateful for further guidance.
We proceed based on the following assumptions:

Worker Name: wk1
Session: session_01jhfxkmfe0vcxwwpf021dtz40
chatId: [email protected]

My question is: with the above initial information, what exact values should be entered in the WAHA parameters section on the n8n side?

Looks like n8n version issues 🤔 Could you try setting it to

1. waha.session
2. waha.chatId

These are values from https://waha-n8n-templates.devlike.pro/chatwoot/WhatsApp___ChatWoot__ChatWoot____WAHA_Messages.json

Hi
Based on my example :

Worker Name: wk1
Session: session_01jhfxkmfe0vcxwwpf021dtz40
chatId: [email protected]

Do you confirm field must set to :

waha.session : chatwoot
waha.chatId : {{ $('Body').item.json.body.conversation.meta.sender.phone_number.replace(/^\+/, '') }}

OR
wk1.session : chatwoot
wk1.chatId : {{ $('Body').item.json.body.conversation.meta.sender.phone_number.replace(/^+/, '') }}
?

Yes, WAHA sends POST request to the endpoint

Hi
I successfully passed the ChatWoot => WAHA stage,
but in the WAHA => ChatWoot stage,
after configuring the nodes,
when testing the workflow on the Create Contact node, I encounter an error message as shown in the image.
I would appreciate it if you could provide guidance.
