How to Add a Product Image Using the PrestaShop Webservice API

What will you learn?

In this tutorial, you will master the art of uploading product images effortlessly through the PrestaShop Webservice API. By following these steps and code snippets, you’ll seamlessly integrate images into your PrestaShop store, enhancing its visual appeal.

Introduction to Problem and Solution

Managing an online store effectively involves adding and updating product images regularly. Visual content plays a vital role in attracting customers and aiding their purchasing decisions. However, manually handling image uploads can be time-consuming, especially for stores with extensive product catalogs. PrestaShop’s Webservice API provides a robust solution to automate this process programmatically.

This guide leverages Python, a user-friendly programming language known for its simplicity and readability. By sending HTTP requests to the PrestaShop Webservice with specific parameters and headers, we can authenticate our requests and instruct PrestaShop to add images to products seamlessly.


import requests

prestashop_url = ""
api_key = "YOUR_API_KEY"
product_id = "PRODUCT_ID"
image_path = "/path/to/your/image.jpg"

with open(image_path, 'rb') as image:
    image_content =

response =
    files=[('image', (image_path.split('/')[-1], image_content))],
    auth=(api_key, '')

if response.status_code == 201:
    print("Image uploaded successfully.")
    print(f"Failed to upload image: {response.content}")

In the provided code snippet:

  • Utilize the requests library for simplified HTTP requests in Python.
  • Define variables for PrestaShop URL, API key, Product ID, and Image Path.
  • Open the specified image file in binary read mode (‘rb’) for transmission over HTTP.
  • Use method to send a POST request with necessary data for adding an image.
  • Basic authentication is handled through provided credentials.
  • Check response status for successful or failed upload.

This method not only automates updates but also enables integration with external systems without manual intervention.

    1. How do I find my API key? To access your Prestashop’s WebService API key, navigate through your dashboard: Advanced Parameters > Webservice > Add new web service key.

    2. What permissions are required for uploading images? Ensure your API key has rights set for “GET”, “POST”, “PUT” operations under resources like ‘products’ or ‘images’.

    3. Can I use this method to update existing product images? Yes! By specifying an existing product’s ID and providing new imagery you can replace current visuals according customer needs or stock changes.

    4. Is there any size limit on images when uploading via API? While Prestashop itself doesn’t impose strict limits through APIs beyond server settings; always optimize photos considering web performance best practices.

    5. Do I need special headers when making these POST requests? The example includes basic authentication headers; depending on setup Content-Type may need specification though typically managed by libraries like Requests seamlessly.

    6. What error codes should I look out for during troubleshooting? Common issues may arise due server-side misconfigurations (5XX errors), unauthorized access (401), or invalid data submission (400).

    7. Is it possible automate batch uploads instead one at time approach shown here? Absolutely! Looping through directories containing respective imagery while adjusting product IDs allows mass updates efficiently.’

    8. How secure is transmitting my API key over HTTP Requests? As long as HTTPS protocol secures connection between client-server communications encryption ensures safety against interceptions; however keep keys confidential & regenerate periodically within admin panels if suspicion arises concerning leaks/security breaches.’

    9. Can non-Python languages achieve similar outcomes interfacing with Prestashop’s WebService APIs? Definitely! Any programming language capable handling HTTP Requests authenticated appropriately regardless whether scripting such PHP/Ruby or compiled languages e.g., Java/C# maintain potential achieving same objectives outlined herein.’

    10. Are there limitations regarding formats types supported when uploading pictures?’ Primarily commonly used web formats JPEG/PNG supported ensuring broad compatibility across devices viewing platforms ensure checking documentation specifics could vary version-version basis.’


Automating tasks like uploading product images via APIs revolutionizes online store management by saving time previously spent on manual asset handling tasks�particularly beneficial for stores with extensive inventories requiring frequent updates to enhance customer engagement visually represent merchandise accurately leveraging technological advancements streamlining operational workflows contributing overall business growth strategies longitudinally.’
