# Added source/ATS and company filtering + source ID fields

jobdataapi.com v4.15.1 / API version 1.17.1

---

This update introduces new filtering capabilities and data enhancements to help you better manage job and company data sources.

## New field for Company source/ATS ID

All company object results now include a `source_id` field – an integer identifier representing the original Applicant Tracking System (ATS) or data source for the company. This field will also be included in the company CSV download file starting with next Sunday's weekly export (note: this is a schema change for the companies.csv file).

Example in API response for company object:
```json
{
  "id": 123,
  "name": "Tech Corp",
  "source_id": 42, // New field
  ...
}
```

## New filters for Company source/ATS ID

We've added three new filtering capabilities (**access pro** subscription required):

A new `company_source_id` parameter is now available across the following endpoints:

- /api/jobs/

- /api/jobsexpired/

Similarly for the /api/companies/ endpoint there now is a `source_id` filter parameter to narrow down companies by their source/ATS ID.

Filter by specific source IDs using our multi-ID syntax (pipe-separated values):

```json
https://jobdataapi.com/api/jobs/?company_source_id=42|56
```

## Added company_id filter to expired Jobs API endpoint

Another addition to the /api/jobsexpired/ endpoint is a `company_id` filter parameter that lets you filter for expired jobs by one or more companies:

```json
https://jobdataapi.com/api/jobsexpired/?company_id=12345
```

## Usage Notes
Source IDs are numeric identifiers without descriptive labels – they're primarily useful for:

- Excluding jobs from specific sources you've already processed

- Grouping results by data origin

- Identifying patterns in source-specific data quality

The `source_id` field will appear in all API responses for company objects, including nested company objects within results from the /api/jobs/ endpoint, as well as the companies.csv download file.
