Can’t update product using REST API

Hey @barotoardi,

As a test for us, I created a new product with a price of $20.

I then placed a PUT request to that product and updated the regular_price to 40 using Postman app. The REST API response showed that the product price was updated to 40.

The test product on the site also reflected that price change which was carried out via the REST API.

This testing indicates that the WooCommerce REST API itself is working as expected with PUT requests.

With regards to testing API calls, we have some information on testing API calls using an App called Postman and I’ve referenced that app below for you.

https://github.com/woocommerce/woocommerce/wiki/Getting-started-with-the-REST-API

I hope this helps.

I can confirm you that using Woocommerce can receive PUT command using curl:

curl -X PUT https://domain_name/wp-json/wc/v3/products/<<product_id>> \
-u <<customer_key>>:<<customer_secret>> \
-H "Content-Type: application/json" \
-d '{"stock_quantity": "70"}'

and quantity successfully changed to 70.

But I can’t do the same thing using Postman and place customer_key and customer_secret in url query like in https://woocommerce.github.io/woocommerce-rest-api-docs/?shell#authentication-over-https

Hi @barotoardi,

and quantity successfully changed to 70.

This means that REST API and WooCommerce are properly working.

But I can’t do the same thing using Postman

We do not provide support for Postman on this forum. If it’s not working the way you think it should work with that software, I recommend reaching out to Postman support directly. It could be that you have the wrong settings but Postman support will be best positioned to assist you and let you know. You can reach their support center via https://www.postman.com/support/.

I’m going to close this thread now. Feel free to open a new topic if you have any further questions.

Best regards.

In postman I was having the same issue as described of not getting the update done.
After adding the header as below, it was possible to update from postman as well:
Content-Type:application/json

Notice that postman by default adds some headers… and default is Content-Type:text/plain

Hi,
I have resolved my problem by migrating woocommerce to other hosting. I still don’t know which server setup that need to change. But after moving to other server, rest api is working instantly without changing any codes. If any of you have some info about server setup, please share. My old server is using Litespeed

Hi @barotoardi,

Can you try the answer that @chasky wrote about adding the Content-type: application/json header to your Postman request on your old host? I believe what you achieved with using CURL also can be achieved by using Postman, since the curl command you shared does contain that specific header.

Best regards.
