I searched for a bit but while I could find API limits, I couldn't find limits for interactions with embedded forms or landing pages with forms in them. If there are no form/landing page limits, why is this? I feel like they could potentially be abused just like an API could be.
If we're switching from Marketo forms and landing pages to our own custom build forms and landing pages using the Marketo API, will we have to suddenly worry about going over all our API limits or will things stay mostly the same?
The forms endpoint is limited to 30 form posts per minute per source IP. (This is discussed in a few past posts.)
Naturally this makes forms orders of magnitude more scalable than REST API-based attempts. Consuming REST calls in response to individual end user activities creates a clear DoS vulnerability.
There's no formal rate limit for LP pageviews.
