1. Install the module
Back office > Modules > Upload a module, choose the modunia-1.1.0.zip file you received by e-mail. The install adds a Modunia AI entry in the left menu.
2. Activate your key
Open Modunia AI, paste the key you received by e-mail, click Activate. On a test copy, no key is asked for.
3. Connect n8n
- In n8n, create a workflow and add a Webhook node, method POST.
- In the node, choose Header Auth, name
X-Modunia-Secret, and a value of at least 12 characters. - Activate the workflow and copy its production URL.
- In Modunia, paste the address, type the same password, tick the data notice, then click Test and save.
4. Choose what leaves
Tick the events your workflows need. Leave "Ignore changes made through the PrestaShop API" on: that is what stops loops when your AI writes back to the store.
5. Send what already exists
The "Send your existing data" section sends what is already in the store once: products, categories, customers, orders. You can stop and resume at any time.
6. Check
The Activity section lists the last sends, with the result and the details of any error. The CSV button exports that list.
If n8n stops answering
Events are kept in a waiting list. After five failures in a row, sending pauses and a banner says so in the back office. Fix the workflow, then click "Send waiting events and resume".
Message format
One POST request per event, in JSON. Headers: X-Modunia-Secret, X-Modunia-Timestamp and X-Modunia-Signature, the last one being an HMAC-SHA256 of "timestamp.body" signed with your password. The body carries the event type and the identifiers concerned; details are read with the PrestaShop API.
