Very crude TypeForm integration for Sanity.io on Zeit’s Now.

get-response.ts

// api/get-response.ts
import SanityClient from "@sanity/client";

const projectId = "<yourProjectId>";
const dataset = "<yourDataset>";

const token = process.env.SANITY_EVENT_TOKEN; // Add to now secrets and .env

const client = SanityClient({
  projectId,
  dataset,
  token,
  useCdn: false
});

// Reformat reponse values
function resolveResponseItem(answer) {
  const { field } = answer;
  if (field.type === "multiple_choice") {
    return answer[answer.type].label;
  }
  return answer[answer.type];
}

export default async (request: NowRequest, response: NowResponse) => {
  const { body } = request;
  const { form_response, event_id } = body;
  if (!form_response) {
    return response.status(404);
  }
  const { form_id, answers, submitted_at } = form_response;
  const res = await client.create({
    _type: "response",
    // Use id path to hide document from public
    _id: `typeform.${event_id}`,
    submittedAt: submitted_at,
    answers: answers.map(answer => ({
      _key: answer.field.ref,
      _type: "answer",
      [answer.field.type]: resolveResponseItem(answer)
    }))
  });
  console.log(res);
  return response.status(200).send(body);
};
