SIDES integration for unemployment claims

Connect HR and payroll data to UI SIDES so separation requests are matched and prefilled. An HR specialist reviews and approves every response. The employer or TPA holds the NASWA agreement and broker ID.

Sample data. Every name and number here is made up.

How it runs.

Separation requests pile up across states, each with its own due date. Keying answers one at a time does not hold up at volume, and paper notices still arrive.

  1. Request from broker

    A connector retrieves separation requests from the SIDES Central Broker.

    Your data

  2. Match and prefill

    Matched to the employee record. Dates and separation details prefilled.

    Automated

  3. HR approves response

    An HR specialist reviews each response, especially separation reason and facts.

  4. Return and record

    Approved response goes back through the broker. Dated record kept.

The rules and limits.

Two official routes
E-Response is a web form for limited claims, with no programming. System Integration is a computer-to-computer link for employers, TPAs and PEOs with volume.
What you sign up for
A participation agreement and broker ID from NASWA. No service fee, but development costs are yours. California also needs a Power of Attorney from TPAs per client.
Testing in California
California's guide requires two rounds: SIDES certification testing of your connector against the broker, then end-to-end testing with the state.
Paper does not end
SIDES reduces paper notices but does not eliminate them. California says a mailed DE 1101CZ is due within 10 days of the mail date.
Security
SIDES uses authentication certificates and encrypted records and files. Requests include Social Security numbers, so access stays limited.

What a person does.

  • An HR specialist approves every response before it is sent.
  • A person decides the separation reason and any misconduct facts.
  • Someone handles paper notices that arrive outside SIDES.

Where we stand: we have not shipped this. It follows our data sync and review-queue patterns. NASWA's developer guide is not public and would come first.

Common questions.

Can you script SIDES E-Response instead?+

No. E-Response is a web tool reached through an emailed authorization code. We could not confirm its terms allow scripting, so this page only covers System Integration.

Who holds the NASWA agreement?+

The employer or TPA completes the participation agreement and gets the broker ID. Public pages do not say how a software contractor fits in, so ask NASWA first.

How long does onboarding take?+

We could not find a published timeline. Expect registration, connector development, certification testing, and California adds end-to-end testing. Some organizations use E-Response in the interim.
