WooCommerce REST API v3 problem: woocommerce_api_authentication_error

Hello,
after upgrading my WooCommerce to the latest version all the communications that used the REST APIs stopped working and started to return this error: {“errors”:[{“code”:”woocommerce_api_authentication_error”,”message”:”Invalid signature – The signature does not correspond.”}]}

Searching the documentation I discovered that the APIs were updated from v2 to v3 in the mean time.
The changelist tells me a generic:
v3 fixes the OAuth implementation to be compliant with the Oauth 1.0a specs.

My question is: how do I know what changed? I’m using the php library but it has not been updated after this release, so I have to change my code by hand and it would be useful to know what I have to look for.

Thanks!

You can view commit history on https://github.com/woothemes/woocommerce/tree/master/includes/api

But the auth docs are here http://woothemes.github.io/woocommerce-rest-api-docs/#authentication Just follow the new instructions.

Thank you for your answer!

I followed the guide but I do not see any difference from my script, I cannot isolate what has changed from the previous version.

Here is what is generated from my script:

GET&http%3A%2F%2Fmy.site.com%2Ffolder%2Fwc-api%2Fv3&oauth_consumer_key%3Dck_various_numbers_and_letters%26oauth_nonce%3D21b11ea0026066a6102bbd8905c7848809e6595e%26oauth_signature_method%3DHMAC-SHA256%26oauth_timestamp%3D1442417198

Signature:
NY5NYVAj5j5tfLry5l8Znmv/c1SYXp0gpgT0XbKqRcE=

Does this seem right? Maybe there is some glaring problem that I don’t see. (I have changed the sensible data but the structure is the same)

@mattiarigotti Here’s what has changed ONLY in v3 (see that we don’t change it in v2): https://github.com/woothemes/woocommerce/pull/8415

If you are having trouble authenticate, I recommend using any ready lib that will work now with WooCommerce without any problems or one of our wrappers: http://woothemes.github.io/woocommerce-rest-api-docs/#official-libraries

This was extremely helpful, thanks.
The only thing I needed was to add a “&” after my consumer_secret while encoding, and now it works like a charm.

Thank you again!

MattiaRigotti,

Thank you, & after consumer secret works fine.
