# The Marketo SOAP API stops working

Calls to /soap/* on Marketo SOAP API stopped working on July 31, 2026.

On July 31, 2026, the Marketo SOAP API reached deprecation and was shut down. Requests sent to /soap/* fail since that date. The interface is no longer available for any calls.

## What to use instead

Call the Marketo REST API at {munchkinId}.mktorest.com/rest/v1/... using an access token obtained from /identity/oauth/token. This transition requires more than changing an identifier, as the REST API authenticates using a LaunchPoint custom service's client ID and secret, which SOAP integrations do not have.

The REST API authenticates with a LaunchPoint custom service's client ID and secret, a credential the SOAP integration does not have.
