-# onboard-verifier
+# OnBoard Submission Verifier
 
-This program runs as a Cloudflare Wrangler worker at https://ysws.limeskey.com. The inital domain redirects to a special Slack Auth link which has my custom bot's Client ID and scopes. Then, after completing a successful Slack Auth, it redirects to https://verify.limeskey.com which takes all this information and does some movie magic to derive the user's Slack ID, Username, and eligiblity status according to the YSWS Unifed Verification Airtable database. Finally, I add I append this data as a URL parameter for the fillout form.
+This program runs as a Cloudflare Wrangler worker at [api.onboard.hackclub.com](https://api.onboard.hackclub.com). It's intended to be used by the Svelte, Rust & WebAssembly frontend at [verify.onboard.hackclub.com](https://verify.onboard.hackclub.com), also hosted by Cloudflare in a Page. 
 
-# Dependencies
-### PNPM
-    `pnpm install`
+This API is used to verify users using Slack and GitHub oAuth codes. The API accepts POST requests with optional Slack and GitHub authorization codes and returns a json struct that includes information about the Slack User and GitHub user, and also checks against the unified YSWS Verification API to see if they're eligible and have verified their ID.
 
-# Build
+### Endpoint
 
-### Wrangler Dev
-    `pnpm wrangler deploy`
+```
+POST https://api.onboard.limeskey.com/api
+```
 
+### Request Payload
 
+The request payload should be in JSON format and can include either or both Slack and GitHub authorization codes.
+
+#### Example Payload
+```json
+{
+  "slack_code": "your_slack_code_here",
+  "github_code": "your_github_code_here"
+}
+```
+
+- `slack_code` *(optional)*: The Slack OAuth code.
+- `github_code` *(optional)*: The GitHub OAuth code.
+
+### Response
+
+If the request is successful, the API will return a 200 response with a URL containing verification information, which includes:
+
+- `secret`: The hashed secret.
+- `slack_id`: The Slack user ID.
+- `eligibility`: The user's eligibility status from Slack.
+- `slack_user`: The Slack username.
+- `github_id`: The GitHub user ID.
+
+#### Example Response
+
+```
+https://forms.hackclub.com/t/9yNy4WYtrZus?secret=5ec501bbb97b6b&slack_id=U04JGJN2B40&eligibility=EligibleL1&slack_user=Ryan+Di+Lorenzo&github_id=LimesKey
+```
+
+### Error Handling
+
+If the request fails, the API will return an error message with the response status.
+
+#### Example Error
+
+```
+{
+  "error": "Request failed with status: 400"
+}
+```
+
+### Example Usage
+
+```rust
+// Example using Fetch API in Rust using wasm_bindgen
+
+#[derive(Serialize, Deserialize)]
+struct ApiPayload {
+    slack_code: Option<String>,
+    github_code: Option<String>,
+}
+
+pub async fn verify_api(slack_code: Option<String>, github_code: Option<String>) -> Result<JsValue, JsValue> {
+    let payload = ApiPayload { slack_code, github_code };
+    let payload_json = serde_json::to_string(&payload).unwrap();
+
+    let mut opts = RequestInit::new();
+    opts.method("POST")
+        .body(Some(&JsValue::from_str(&payload_json)))
+        .mode(RequestMode::Cors);
+
+    let request = Request::new_with_str_and_init("https://api.onboard.limeskey.com/api", &opts).unwrap();
+    let response_value = JsFuture::from(web_sys::window().unwrap().fetch_with_request(&request)).await?;
+    let response_text = JsFuture::from(response_value.dyn_into::<web_sys::Response>()?.text()?).await?;
+
+    Ok(response_text)
+}
+```
+
+### Development
+Build the program using `pnpm install` and run `pnpm wrangler dev` with the required enviornment variables.
