Question - SOAP Interface and Marketo

HI Lisa,

Marketo provides multiple API's to "talk" with other apps

• The SOAP API (http://developers.marketo.com/soap-api/) was the first server side API made available by Marketo. Many third party products use it, but it has stopped evolving for a while and lask many possibilities
• The REST API (http://developers.marketo.com/rest-api/) is the most recent server side API, more compréhensive

In both case, it will take a developper to develop the connection to these API's: these are inbound API's, meaning that the other app will have to connect to Marketo and manage the transactions.

There are also some client side API's (that enable to connect to Marketo from a visitor's browser).

The question's a bit vague... Marketo supports inbound SOAP (though that API is deprecated and shouldn't be used for new projects). Marketo's outbound API is webhooks, which traditionally use either form-like/URL-encoded or REST-like/JSON communications but could use SOAP. An intermediate webhook can also be used as a gateway to a (2nd-hop) remote SOAP service.

You should elaborate on your requirements to get a more precise answer.
