API Call to Get Email Addresses on Specific Target List

[boognish]

Hi guys, EspoCRM is such a great piece of software that I hardly ever get to communicate with you guys unless I'm stuck but that's what I am today. Maybe I'm just missing something obvious.


I would like to make a GET request to the API to fetch email addresses on a specific target list and then add to it if the email doesn't exist. The "adding" bit can wait until I figured out the "getting" bit.


If I call the API on entity "TargetList" I get the lists in my system, and can see the entryCount attributes, but how to get the actual email addresses programmatically? I would be calling the API from another application that will allow that client app to take action based on whether or not an email already exists on a specific target-list.

Any ideas would be greatly appreciated as always.

Okay, I see in the network tab in Chrome dev tools the following query string, so I kind of answered my own question here.

primaryFilter=&select=salutationName%2CfirstName%2ClastName%2CmiddleName%2Cname%2Cstatus%2CemailAddressIsOptedOut%2CemailAddress%2CemailAddressData%2CcreatedAt&maxSize=50&offset=0&orderBy=createdAt&order=desc

This will work, I suppose at first glance, but the above query string is a little hard to work with and I'd much rather use the API with a JSON query like what is well documented. But I have run into a snag with the espocrm-api-client.js code provided at the below link:

https://docs.espocrm.com/development...ascript-nodejs


My code snippet:

const client = new Client(
'<MY URL>',
'<MY API KEY>',
);
var params = {
    maxSize: 5,
    where: [
  {
    type: 'equals',
    attribute: 'type',
    value: 'Customer'
  }],
    select: 'id,name',
    };
    client.request('GET', 'Account', params)
    .then(
    (response) => {
    console.log(response);
   }
)

I am getting the following error:

Uncaught (in promise) TypeError:
The "listener" argument must be of type Function. Received type object

EDIT: I should mention that this is from a React component if that is helpful to know. The above code is taken from the example in the docs and not related to my initial query.
