Are activity types fixed?

[Anonymous]

We are interested in fetching lead activities from marketo with REST API. We are using

/rest/v1/activities/types.json and /rest/v1/activities.json endpints for that purpose. I have following questions regarding to this.

- Are activity types returned from /rest/v1/activities/types.json fixed ? Can they change depending on activated integrations or system configuration?

- Are activity types ids the same for each marketo account ?

Thanks in advance

In the short term, tehse activity type ids will most likely stay constant. Looking at a longer time horizon, it is best practice to decouple the dependence on hardcode variable values. I would recommend polling the  Get Activty Types API to make sure these actitvity type variable values are in sync.

Hi Murtza, 

Thanks for your replay.
Just to clarify, let's say that we have a use case that we want to fetch `Visit Webpage` activities for different marketo instances. Can we assume that `Visit Webpage` activity type id is equal `1` for all instances (like we have right now on our instance) and use it for filtering, or safer is to determine activity id by name from  /rest/v1/activities/types.json endpoint before ?

Generally, yes. The Activity Types returned from this endpoint are static for an individual Marketo instance. I would still recommend calling this endpoint at least once for each Marketo instance.
