# Introducing ERA last received timestamps

> Stedi's List Enrollments and Retrieve Enrollment API responses now return a 'Last ERA Received At' timestamp for ERA transaction enrollment records.

Product: ERAs & transaction enrollment

Stedi's [List Enrollments](https://www.stedi.com/docs/healthcare/api-reference/get-enrollment-list-enrollments) and [Retrieve Enrollment](https://www.stedi.com/docs/healthcare/api-reference/get-enrollment) API responses now return a [`lastEraReceivedAt`](https://www.stedi.com/docs/healthcare/api-reference/get-enrollment#response.lastEraReceivedAt) timestamp for ERA [enrollment records](https://www.stedi.com/docs/healthcare/transaction-enrollment).

The timestamp contains the last time Stedi routed a production [Electronic Remittance Advice (ERA)](https://www.stedi.com/docs/healthcare/claim-responses-overview#835-electronic-remittance-advice-era) for the combination of [NPI](https://www.stedi.com/docs/healthcare/national-provider-identifier), Tax ID, and payer listed in the enrollment record. For example:

```jsonc
{
  "id": "db6675c5-7bg7-4af9-8c68-a54a336d2911",
  "transactions": {
    "claimPayment": {
      "enroll": true  // ERA enrollment record
    }
  },
  "lastEraReceivedAt": "2026-03-27T05:31:56Z", // Timestamp of last ERA received
  ...
}
```

You can use the `lastEraReceivedAt` field to troubleshoot gaps in a payer’s ERA delivery or find payers that have stopped sending remittance.

## Availability

`lastEraReceivedAt` is only populated for ERA transaction enrollments, not enrollments for other transaction types.

The field is omitted from enrollments that haven't yet received a production ERA.

## Filter by the last ERA received timestamp

You can use the [List Enrollments](https://www.stedi.com/docs/healthcare/api-reference/get-enrollment-list-enrollments) endpoint's new [`lastEraReceivedFrom`](https://www.stedi.com/docs/healthcare/api-reference/get-enrollment-list-enrollments#query.lastEraReceivedFrom) and [`lastEraReceivedTo`](https://www.stedi.com/docs/healthcare/api-reference/get-enrollment-list-enrollments#query.lastEraReceivedTo) query parameters to filter ERA enrollments by the timestamp of the last ERA received. For example:

```jsx
curl "https://enrollments.us.stedi.com/2024-09-01/enrollments?lastEraReceivedFrom=2025-01-01T00:00:00Z&lastEraReceivedTo=2025-03-31T23:59:59Z" \
  -H "Authorization: Key <api_key>"
```

## Sort by the last ERA received timestamp

Use `lastEraReceivedAt` as a [`sortBy`](https://www.stedi.com/docs/healthcare/api-reference/get-enrollment-list-enrollments#query.sortBy) parameter for the [List Enrollments](https://www.stedi.com/docs/healthcare/api-reference/get-enrollment-list-enrollments) endpoint to sort by your most- or least-recently active ERA enrollments.

```jsx
curl "https://enrollments.us.stedi.com/2024-09-01/enrollments?sortBy=lastEraReceivedAt:desc" \
  -H "Authorization: Key <api_key>"
```

## Stedi portal

The **Last ERA received at** field is available in the Stedi portal’s enrollments list view as a filter.

The field also appears in the enrollment detail view.
