Here are answers to the most frequently asked questions about Marketo REST and SOAP APIs.
Q: What are the main differences between the Marketo REST and SOAP APIs?
A: While the ability to push/pull specific data via REST and SOAP APIs mostly overlaps, there is certain functionality that only exists in either REST or SOAP APIs. In terms of performance, the REST API has better throughput than the SOAP API. In terms of the authentication model, the REST API has an authentication model that uses an expiring token. Our REST API also provides access to Marketo assets.
