Failed to load resource: the server responded with a status of 400 ()

I connect my Zencart to my Square Sandbox using Square_webpay plugin, when I try to make test transaction nothing appends, so I decide to check if there’s any error with CTRL+SHITF+J, I got the following error : Failed to load resource: the server responded with a status of 400 ()

Since this is with the Zencart integration I’d recommend reaching out to the for assistance. The one thing I did notice is that you have a sandbox application ID configured and a production location_id which is ML31PZ0FGC1KM. You won’t be able to with production values configured with a sandbox application ID. You’ll need to make sure that you have all sandbox credentials configured for testing in sandbox. :slightly_smiling_face:

Hi Bryan,

When I try to connect directly with the sandbox, zencart connect status is always yellow.

So what I did, I made the first connection with Production parameters, when connexion is established (green), I change the value of the OAuth for Sandbox parameters.

I didn’t found any documentation to connect Zencart webpay to Sanbox.

maybe you can help, because is bit complicated to understand how everything works

When I check inside API LOG I saw connexion, but square don’t want to turn on inside zencart
