401 Unauthorized

Hello guys,
Im trying to create WooCommerce payment gateway for viva payments and getting always 401 error when trying to verify the transaction within my php code, in console it works perfectly.. Also getting 401 when trying using firefox plugin.

Any clue what's going on with this???

Hello @feios

You are getting a 401 (Unauthorized) error because the header you are sending is incorrect.
The firefox plugin is not forming a valid Authorization header.
You can try Google's Postman and choose Basic Auth to enter your API Credentials.

For your php code, you can check the samples here
