CRM Extension data fetch response time

Developer Support APIs & Integrations
1

Hi,

When we built our first CRM extension, we found that HubSpot had strict requirements for the response time to the data fetch request. If our app didn’t respond within a # of milliseconds, the CRM extension displayed a load error.

Is there any official requirement for the response time of the data fetch? We are loading data from an on-premise system which may take over a second to respond. We want to make sure this won’t be an issue before continuing development.

Hey @lynton ,

The info on this topic should still be valid: https://community.hubspot.com/t5/APIs-Integrations/CRM-Extension-Timeout/m-p/273225/highlight/true#M24823

The CRM data fetch request has a timeout of 5 seconds.
