How to list all attachments for a product in Zoho Desk

Retrieving all file attachments linked to a specific product record in Zoho Desk requires a single authenticated GET request to the products attachments endpoint — here is exactly how to do it.

Why this matters

When managing a product catalogue in Zoho Desk, agents and developers often need to audit or display every file associated with a product — think spec sheets, warranty documents, or images. Automating this retrieval saves time compared to clicking through the UI and is essential for integrations that sync product assets to external systems. Knowing the correct endpoint and parameters up front prevents wasted debugging time.

Step-by-step

Step 1. Confirm your OAuth scopes are in place.

Before making any API call, verify that your OAuth token includes the necessary Zoho Desk scopes. At minimum you will need Desk.settings.READ or a broader Desk.settings.ALL scope, along with Desk.basic.READ for organisational access. Without these, the API will return an authorisation error. ^[7]

Step 2. Identify the target product ID.

You need the unique productId for the product whose attachments you want to list. This identifier is typically visible in the Zoho Desk admin panel under the Products section, or you can retrieve it programmatically from a prior products list call. Keep this value handy — it forms part of the request path. ^[1]

Step 3. Construct the GET request.

Send an HTTP GET to the following endpoint, substituting your actual product identifier:

GET /api/v1/products/{productId}/attachments

The endpoint accepts two parameters:

| Parameter | Type | Description |

|---|---|---|

| productId | string (path) | The unique ID of the product record |

| p | dict / query params | Optional pagination or filter parameters |

^[1]

Step 4. Make the call using the Python client (if applicable).

If you are working with a Python-based Zoho Desk client, the method signature looks like this:

def list_all_attachments(self, productId: str, p: dict = None):
    return self.c.request("GET", f"/api/v1/products/{productId}/attachments", p, None)

Pass the product ID as a string and, optionally, a dictionary of query parameters as the second argument. When p is omitted or set to None, the API returns the default attachment listing without additional filtering. ^[1]

Step 5. Parse the response.

A successful response will contain the list of attachment objects for that product. Each object typically includes metadata such as the file name, size, and a reference identifier. Iterate over the returned collection to display, download, or process each attachment as your use case requires. ^[1]

Step 6. Handle pagination if needed.

The p parameter supports pagination controls. If the product has a large number of attachments, pass appropriate page or offset values inside the p dictionary to retrieve subsequent pages of results. ^[1]

Common pitfalls

• Missing or insufficient OAuth scopes. The Zoho Desk OAuth configuration requires explicit scope declarations. If your token was generated without the relevant Desk.settings or Desk.basic scopes, requests will fail with a permissions error. Review your scope list carefully before troubleshooting the endpoint itself. ^[7]

• Incorrect product ID format. The productId must be passed as a string in the path. Passing an integer or a malformed identifier will result in a 404 or similar error. Always validate the ID against a known product record first. ^[1]

• Confusing product attachments with ticket attachments. Zoho Desk has separate endpoints for tickets, contacts, and products. Make sure you are calling /api/v1/products/{productId}/attachments and not a ticket-level attachments route — the two are not interchangeable. ^[1]

What to check

• OAuth token validity: Confirm your access token has not expired and includes the correct Desk scopes before making the request. ^[7]
• Product ID accuracy: Cross-reference the productId you are using against the Zoho Desk admin panel to ensure it maps to the intended product record. ^[1]
• Response pagination: If the returned attachment count seems lower than expected, verify whether additional pages exist by checking pagination metadata in the response and re-querying with the p parameter. ^[1]
