Hello everyone, We’d like to share an update on rate limiting in the CLI. CLI version 4.4.0 introduces new signatures for local theme development. When you run shopify theme dev, the CLI now attaches specific headers to the requests it sends to your storefront. This gives storefront a clear signal…

Same, completely blocked from working right now, with a go-live deadline tomorrow. VPN does nothing for me.

I’m not using the --password flag. I also just tried shopify auth logout and shopify auth login just in case. Always the first request goes through successfully and then the 429s hit. • 08:18:14 Request » GET 200 / 1252ms • 08:18:15 Request » POST 200 /shopify_pay/accelerated_checkout 244ms •…

I’m also getting waves of 429’s - where I can’t use the cli/dev tool at all, and thus unable to get any work done. When trying to access anything in the browser, it just says “Your connection needs to be verified before you can proceed”. Without any available method of doing that. Tried updating the…

Follow-up: any call to /cart.js or /cart/add.js triggers it… and then I get 429s on everything for 10 minutes plus. Don’t even have to do multiple requests.

Hi @stephanie-shopify , thanks for the response. It is nice to know that the issue is being actively worked on. I am no longer receiving any 429s and am exclusively receiving 403s for everything. I cannot develop at all as I am immediately blocked no matter if I change my IP address or switch to a …

Hi, I’m working on a Shopify app. The flow requires clearing the cart /cart/clear.js and then adding a product to the cart /cart/add.js, which worked perfectly fine last year. However, starting today, I’m seeing a 403 error on the add request with the message: “Your connection needs to be verified b…

Hi, same here. I cannot develop at all like @sanico_software . I’m receiving 403s for almost everything. EDIT: Also, if local works for a while somehow, adding a product to the cart is impossible.
