Curios to see what's everyone's workflow these days to handle form submissions on websites hosted on Cloudflare Pages. I am building a new website with Astro JS and planning to host it on cloudflare pages. Ideally, I am looking to store the responses in google sheets and then also sending myself a notification on discord or slack (or a combination of both). I am looking into cloudflare workers and it looks like that's one way to do it, just curious to see if someone has better insights or options (ideally something with no limits and free, I am aware of services like formspree)

Hi folks, what is Cloudflare Workers user agent to be exact? I'm deploying Astro SSR on Workers but when fetching to my WordPress REST API that hosted on shared hosting, its always return 403. However, when I tried to deploy the Astro site on Vercel it works and able to fetch the endpoint.

Maybe I need to allow the Workers user agent or there are others workaround to solve this?

It might be blocking on something else? Workers are designed to be detectable by default, so if your hosting provider doesn’t want Workers to hit their service, that might be it?

Hello, I’m Allie!•5/15/25, 5:10 PM

The neat thing with JSON is that JSON schema validation is native in VSCode(and many other editors). Just add

node_modules/wrangler/config-schema.json

node_modules/wrangler/config-schema.json

node_modules/wrangler/config-schema.json

node_modules/wrangler/config-schema.json in the

$schema
