Event Analytics pagination cursor "after" does not work

[Andrea Dielman]

Referring to: GET /events/v3/events/

A successful call to hubspotClient.events.eventsApi.getPage() returns the "paging" object where you find the "after" cursor (paging.next.after). For instance, "

However, if you're trying to paginate through your events, you'll find that any "after" cursors returned do not work, meaning that you're only able to query the first page of events.

I've tried this with several different objects. Every time I try to paginate, the first page contains 20 events, and the next returns 0. I've even tried to insert the cursor as a string directly into my query, resulting in nothing being returned.

Additionally, it appears that the Hubspot client is attempting to interpret the cursor as an ISO date, even though it's in this format: "MTcxMjY5MDQ1MDM2MnwwLTF8NzA4MDM5NjM0NXw2LTI3NTgyNDU5fC03NTgwNjg4Mjk%3D"

Pagination Code

async function getHubspotEvents(eventType, after = undefined) {
  let allEvents = [];
  try {
    while (true) {
      console.log("after", after);
      const apiResponse = await hubspotClient.events.eventsApi.getPage(
        undefined,
        eventType,
        after
      );
      console.log("apiResponse.results.length", apiResponse.results.length);
      allEvents.push(...apiResponse.results);
      console.log("apiResponse.paging", apiResponse?.paging?.next);
      if (apiResponse?.paging?.next) {
        after = apiResponse?.paging?.next?.after;
        console.log("set after", after);
      } else {
        return;
      }
    }
  } catch (e) {
    e.message === "HTTP request failed"
      ? console.error(JSON.stringify(e.response, null, 2))
      : console.error(e);
  }
  return allEvents;
}

(async () => {
  const atcs = await getHubspotEvents("pe8778399_add_to_cart_v3");
  console.log(atcs.length);
})();

Putting the cursor directly into the query

async function getHubspotEvents(eventType, after = undefined) {
  let allEvents = [];
  try {
    while (true) {
      console.log("after", after);
      const apiResponse = await hubspotClient.events.eventsApi.getPage(
        undefined,
        eventType,
        (after =
          "MTcxMjY5MDQ1MDM2MnwwLTF8NzA4MDM5NjM0NXw2LTI3NTgyNDU5fC03NTgwNjg4Mjk%3D")
      );
      console.log("apiResponse.results.length", apiResponse.results.length);
      allEvents.push(...apiResponse.results);
      console.log("apiResponse.paging", apiResponse?.paging?.next);
      if (apiResponse?.paging?.next) {
        after = apiResponse?.paging?.next?.after;
        console.log("set after", after);
      } else {
        return;
      }
    }
  } catch (e) {
    e.message === "HTTP request failed"
      ? console.error(JSON.stringify(e.response, null, 2))
      : console.error(e);
  }
  return allEvents;
}

(async () => {
  const atcs = await getHubspotEvents("pe8778399_add_to_cart_v3");
  console.log(atcs.length);
})();

Hi @andreadielman
The problem is putting after to occurredAfter?: Date(the third param).
after is the eighth parameter in getPage method.
Workable example:

async function main() {
  let allEvents = [];
  let after;
  try {
    while (true) {
      console.log("after", after);
      const apiResponse = await hubspotClient.events.eventsApi.getPage(
        undefined,
        eventType,
        undefined,
        undefined,
        undefined,
        undefined,
        undefined,
        after
      );
      console.log("apiResponse.results.length", apiResponse.results.length);
      allEvents.push(...apiResponse.results);
      console.log("apiResponse.paging", apiResponse?.paging?.next);
      if (apiResponse?.paging?.next) {
        after = apiResponse?.paging?.next?.after;
        console.log("set after", after);
      } else {
        return;
      }
    }
  } catch (e) {
    e.message === "HTTP request failed"
      ? console.error(JSON.stringify(e.response, null, 2))
      : console.error(e);
  }
  console.log(allEvents);
}
