verify_discord_signature
Script
verify_discord_signature Verify HTTP signatures coming from Discord. public_key should be the Ed25519 public key from Discord, as a hex string body should be the request body as a string. If you have a JSON object as the request body, use JSON.stringify. signature should be the X-Signature-Ed25519 header timestamp should be the X-Signature-Timestamp header
You must return a 401 error and return early if this function returns false, otherwise you will pretty quickly get a big scary warning from Discord that your endpoint has been removed. Note that you'll only be able to add one once you've integrated this correctly. As this function only deals with strings, it doesn't matter whether you use an Express or web endpoint.

pipedream
Script
Pipedream helpers Pipedream offers an Accounts API to handle OAuth for you, automatically, and for free. How to do it is covered in this guide . The helper functions below can make it easier to work with various Google API. For example, I used them like so to get all my free/busy times for this week from all my google calendars: import { pipeDreamGoogle } from "https://esm.town/v/stevekrouse/pipedream";
const accountId = "REPLACE_WITH_YOUR_GCAL_ACCOUNT_ID_FROM_PIPEDREAM";
const calendar = await pipeDreamGoogle("calendar", accountId);
// Function to get free/busy information
async function getFreeBusyTimes(calendarId: string) {
const now = new Date();
const startOfWeek = new Date(now);
startOfWeek.setDate(now.getDate() - now.getDay());
const endOfWeek = new Date(startOfWeek);
endOfWeek.setDate(startOfWeek.getDate() + 6);
const requestBody = {
timeMin: startOfWeek.toISOString(),
timeMax: endOfWeek.toISOString(),
items: [{ id: calendarId }],
};
const freeBusyResponse = await calendar.freebusy.query({
requestBody,
});
return freeBusyResponse.data.calendars[calendarId].busy;
}
const calendars = (await calendar.calendarList.list()).data.items;
const freeBusy = await Promise.all(calendars.map(calendar => getFreeBusyTimes(calendar.id)));
console.log(freeBusy); In order for this to work you need to follow the instructions in this guide to save your pipedream API key into your Val Town Environment Variables under pipedream , then connect the google account you care about to Pipedream, and copy it's Pipedream "account id" into your val code. Let me know if you need any help by commenting on this val!
