Web service - update product returns error 400 BAD REQUEST

[encodia]

I'm trying to update my products via web service (Prestashop 1.5.3.1).

I downloaded the PSWebServiceLibrary.php file and run the examples; after changing

 

const psCompatibleVersionsMax

 

to make it run with 1.5.3.1, I could run the examples.

 

I can read customers or products, but if I try to update one of them, I get a 400 error (Bad Request).

What is the problem?

 

Is there another way to update products? I need to change prices with a batch process.

 

Thank you

Apache error logs doesn't report anything concerning this error.

No one experiencing this problem? Searching on Google there are a lot of questions / bug tracking about this problem, but I couldn't find any solution...

 

Thanks in advance to whoever can tell me anything about this error.

Solved. After enabling 'display_error' in defines.inc.php, the PUT response shows that some field cannot be updated, so it has to be removed from the XML.

Hi there

 

i also downloaded the PSWebServiceLibrary.php but i still get nothing in 1.5.3 can you please help me out and tell me what are the steps or pre requisite to run the web service .

 

what i get is 302 error.

I had the same issue with updating a product through PSWebServiceLibrary.php, here was the problem:

<message><![CDATA[parameter "position_in_category" not writable. Please remove this attribute of this XML]]></message>

If you enable debug on the library it gives you the HTTP responses required to track down the issue.

Same issue here.

Using  version 1.6 but in this case, by eliminating "postion_in_category" parameter, the error is still happening.

Is there any way to find out if any other paramater is causing this issue?

 

Thanks !!

[joelPresta]

Thanks for the solution!

 

Running PS 1.6.0.9 here and had to remove the parameters "manufacturer_name" and "quantity"...

 

PS: I changed PS to debug mode in defines.inc.php:

define('_PS_MODE_DEV_', true);

[stefan2]

same problem here (ps 1.6.0.14)

_PS_MODE_DEV_ = true not helping

 

I PUT very simple XML to change "active" only:

<?xml version="1.0" encoding="UTF-8"?><prestashop xmlns:xlink="http://www.w3.org/1999/xlink"><product><id>115880</id><active>0</active></product></prestashop>

and still have:

HTTP RESPONSE HEADER

HTTP/1.1 400 Bad Request

 

There is all OK with update the customer (with example file) but not with products.

It works! Thanks JoelPresta, you save my day!

I didn't know how to see the error. At the xml information you will see at the end the error information.

Thanks for the solution!
