npm SDK

The SDK lives in the Reachase monorepo under sdk/ and is published as@reachase/sdk. It works in Node.js 22+ and edge runtimes with fetch.

npm install @reachase/sdk

Initialize the client with your API key and the ingest base URL. Use resource methods to list forms, submit data, list bookings, and book meetings.

import { Reachase } from "@reachase/sdk";

const reachase = new Reachase({
  apiKey: process.env.REACHASE_API_KEY!,
  baseUrl: "http://localhost:3001",
});

const forms = await reachase.forms.list();
const submission = await reachase.forms.submitByApiUuid(forms[0].apiUuid, {
  name: "John Doe",
  email: "[email protected]",
  message: "Enterprise inquiry",
});

• reachase.forms.list() — list forms for the authenticated organization.
• reachase.forms.submitBySlug(orgSlug, formSlug, fields) — public embed-style submit.
• reachase.forms.submitByApiUuid(apiUuid, fields) — authenticated API submit.
• reachase.bookings.list(params) — list bookings with optional filters.
• reachase.schedule.availability(orgSlug, eventSlug) — open scheduling slots.
• reachase.schedule.book(orgSlug, eventSlug, input) — create a booking.

Use verifyWebhookSignature to validate X-Reachase-Signature on incoming webhook requests.

import { verifyWebhookSignature } from "@reachase/sdk";

const isValid = verifyWebhookSignature(
  rawBody,
  request.headers.get("x-reachase-signature") ?? "",
  process.env.WEBHOOK_SECRET!
);
