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.
Q: What features are available in the REST API that are not available in the SOAP API?
A: List of lists API, check if lead is a member of list API, remove a lead from a list API, Usage API, and Error API are only available with the REST API.
Q: Does Marketo plan to deprecate the SOAP API?
A: There is no plan to deprecate the SOAP API.
Q: Are there plans to increase the number of APIs available for the SOAP API?
Q: Are there plans to increase the number of APIs available for the REST API?
A: Yes. REST is the primary focus of Marketo’s API development at this time.
