Hi All 👋

I’ve been attempting to make use of the V3 List Membership API, but I’m coming up against an issue.

```lia-code-sample
const hubspot = require('@hubspot/api-client');

const hubspotClient = new hubspot.Client({"accessToken":"YOUR_ACCESS_TOKEN"});

const listId = "listId";
const after = undefined;
const before = undefined;
const limit = 100;

try {
 const apiResponse = await hubspotClient.crm.lists.listAppMembershipApi.getPage(listId, after, before, limit);
 console.log(JSON.stringify(apiResponse, null, 2));
} catch (e) {
 e.message === 'HTTP request failed'
 ? console.error(JSON.stringify(e.response, null, 2))
 : console.error(e)
}

```

I’m getting this type error

`TypeError: Cannot read properties of undefined (reading 'listAppMembershipApi')`

The auth token is correct, and the listId is also correct. Any ideas what might be causing this?

I know it’s currently in Beta, so maybe it’s just not working?

Many thanks in advance

Hi @EddBrisley,  
Thank you for asking the Community!  
So you are using the [Lists (Beta) API](https://developers.hubspot.com/docs/api/crm/lists), right?  
Which action are you trying to do exactly with this endpoint, please?  
I’d like to invite a couple of subject matter experts to this conversation: Hi @Bob2245, @GRajput and @himanshurauthan do you have suggestions to help @EddBrisley, please?  
Also, if anybody else has anything to add and/or share, please feel free to join in the conversation 🙂  
Thank you very much and have a lovely day!  
Best,  
Bérangère

Hi Bérangère, yeah absolutely, and thanks for your response 🙌

Yes it’s the Lists Beta API. The specific endpoint I’m working on is the list membership endpoint \</crm/v3/lists/{listId}/memberships\>

I’m essentially trying to return a list of deal IDs of the current members of a specific list.

If I try to access the endpoint via something like Postman it’ll work just fine. Also if I structure the API call differently and use the axios library it’ll work too. For example:

```lia-code-sample
 const options = {
 method: 'GET',
 url: `https://api.hubapi.com/crm/v3/lists/${listId}/memberships`,
 headers: {
 Authorization: `Bearer ${hubspotApiKey}`
 }
 };

```

but it’s just odd that you’ll run into a type error when using the standard method shown in the documentation. i.e:

```auto
try {
 const apiResponse = await hubspotClient.crm.lists.listAppMembershipApi.getPage(listId, after, before, limit);

```

Perhaps I’m just showing my inexperience! But i suspect others might run into an issue (?)  
Let me know if I’m just barking up the wrong tree 😅  
Many thanks

Hi, I have exactly the same issue. Did you have found any solution?

Thanks,

Hi @cpradalier  
Yeah I found a solution (if you can call it that) by using the Axios library. Feel free to use the below as a starting point to resolving your issue, and let me know if you have any questions 👍

```lia-code-sample
const axios = require('axios');

exports.main = async (event, callback) => {

 let toObjectIds = event.inputFields['toObjectIds']; // in this example, we're pulling in an array of data from a previous step, for comparison, but adjust this to your needs
 toObjectIds = JSON.parse(event.inputFields['toObjectIds']); 

 const hubspotApiKey = << put your secret here >>;
 const listId = 1111; // this represents the list you're targeting

 const options = {
 method: 'GET',
 url: `https://api.hubapi.com/crm/v3/lists/${listId}/memberships`,
 headers: {
 Authorization: `Bearer ${hubspotApiKey}` 
 }
 };

 let responseData = null;
 let recordIds = [];

 try {
 const response = await axios(options);
 responseData = response.data;
 console.log(responseData);

 recordIds = responseData.results.map(item => item.recordId); // In this example I'm mapping the returned data to an array, but you don't necesserily have to do this. If you don't, it'll simply return as a string literal. 

 } catch (error) {
 console.error('Error:', error);
 throw error
 }

 callback({
 outputFields: {
 responseData: JSON.stringify(responseData)
 }
 });
};

```
