REST Incident eBonding with attachments

[John_123_Snow]

I need to do incident eBonding with another ServiceNow instance, so on my business rule I post the incident without attachment.. I get response with the sysID and I need to later use for my Attachment API, because in the Attachment API you need to specify the sysID of the record that has to be attached, hows is this achievable technically? Does it mean that I need to pass the sysID from my response to another post and call the Attachment API from Instance B?

Hi,

I am also facing the same issue without changing any data my new attachments are not getting transferred so if no data has been updated but new attachments getting added those are not transferred to another instance.

do you find any solutions to it.
