Noob question: How to connect Hubspot to other CRM using API


Hello everyone,

since this is my first time doing this, I have some very dumb question.

I was given the task of integrating Hubspot into other CRM through API, and I’m not sure how is this done.
So the basic flow is like from Hubspot part of the contacts should be sent to other CRM and when status on contacts is changed in other CRM it should be also changed in HubSpot.

I have API documentation of other CRM but I’m not sure what to do with it and how to do integration? :confused:


Hi @frankhudson,

For getting and updating contacts in HubSpot, you’ll want to take a look at the contacts API documentation. That’s probably the best place to get started, as it details all the ways you can interact with HubSpot contacts via the API:


I’ve just read that, and also I’ve received Affiliate API documentation from other CRM, but still I’m not quite sure where should I write those functions?


HI @frankhudson,

You’ll have to write/host your code externally, as HubSpot doesn’t host server-side scripts/code. Heroku has a free tier of app hosting that might be a good place to get started:
