[SOLVED] Is there a communication limit for REST Request and Response in Outlook Add-in?

Is there a communication limit for REST Request and Response in Outlook Add-in?

I'm building an Outlook add-in using Office.js, and I'm using REST to communicate with external applications. Are any of the following limitations present in the Outlook add-in?

Capacity of POST requests
Number of REST sends and receives

Solution

OfficeJS doesn't have any limitation on the number of REST calls or capacity. You just need to keep in mind CORS restrictions.

The same-origin policy enforced by the browser prevents a script loaded from one domain from getting or manipulating properties of a webpage from another domain. This means that, by default, the domain of a requested URL must be the same as the domain of the current webpage. For example, this policy will prevent a webpage in one domain from making XmlHttpRequest web-service calls to a domain other than the one where it is hosted. Read more about that in the Addressing same-origin policy limitations in Office Add-ins article.
