Usage with Dynamic Data

You can use workflow data to dynamically update products:

// In a previous ExecuteScript node
ctx.data = {
  product_id: ctx.data.producto.id,
  price: ctx.data.nuevo_precio,
  active: ctx.data.stock > 0
};

Example Workflow: Price Sync

[HTTP Trigger] -> [Get CSV data] -> [Loop] -> [PrestaUpdateProduct] -> [Notification]

1. HTTP Trigger: Receives webhook with price updates
2. Get CSV data: Parses the price file
3. Loop: Iterates over each product
4. PrestaUpdateProduct: Updates price in PrestaShop
5. Notification: Sends summary via email/Slack

Notes

• The module first gets the current product and then applies the updates
• Multilingual text fields (name, description) are updated in the default language
• If no fields are specified for update, the node returns a message indicating this
• The PrestaShop API uses XML internally, but the module handles the conversion automatically

Common Errors

Error	Cause	Solution
”Missing credentials”	Empty urlBase or apiKey	Verify credential configuration
”Product not found”	Incorrect ID or reference	Verify the product exists
”Authentication error”	Invalid API Key	Generate a new API Key
”No permissions”	API Key without permissions	Enable product permissions in the backoffice
