Export/Imprt data from One Hubspot Account to Another via API
SOLVE
I want to Export contacts data (Having all activities, notes, calls, emails, meetings etc.) from one Hubspot Account and Import to another Hubspot account.
I came to know from Hubspot team that we should use Engagement APIs
I want to know, does the same APIs perform the Export and Import calls collectively, or I need to perform Get and Post actions differently?
If differently then where we would save the data, after Export?

As @dennisedson said, you'll need to call the GET to query all the engagements from the source portal, then call POST to the target portal for each engagement. You will also need to call the Associations API in the target portal to associate the engagement with the companies/contacts/deals. If you want to save/export the data at the same time, you could write code to save it to a SQL database, CSV file, GSheet, etc.
You run HubSpot export and import automatedly with Help Desk Migration. This service ensures zero downtime and supports custom data migrations, so you can tailor it to your needs. Other possibilities include delta migration, concierge service, scheduled migrations, and demo migration to check how it goes.
