create incident with an attachment rest api?

[Kiran Kumar 76]

we have a use case where third party create an incident with an attachment if it has one, I see we have two separate APIs to create incident  and add attachment .

so in this case how to combine these both APIs so that i create an incident and add attachment to the same after creating

The Attachment API requires that it have the sys_id of the record it is associated with so I don't think the two APIs can really be combined because the incident would need to be created first.

However, you can create a Script REST API so that you only need to use one API. https://nowlearning.servicenow.com/lxp/en/now-platform/now-platformname?id=learning_course_prev&cour...
