WebEngage integration with Segment.com is of 2 types: Basic and Advanced. In both these integrations, you do not have to separately integrate the WebEngage SDK.
With Basic integration, you will be able to send all user & events data from Segment to WebEngage for any of your sources – website, mobile apps, server. You will also be able to use the following engagement channels on WebEngage: SMS, On-site, Web Push and Email. The only constraint with Basic Integration is that you will not be able to use Push and In-app engagement channels through WebEngage.
With Advanced integration, you will be able to send all user & events data from Segment to WebEngage for any of your sources – website, mobile apps, server. Also, you will be able to use all the engagement channels: Push, In-app, SMS, On-site, Web Push and Email.
