Create datasorce to specific organisation by api

Hi, I would like to know if you can help me with the following: I need to create a datasource in a specific organization using the api rest, but WITHOUT changing the current organization. If in the json I add orgId when creating the organization, it does not respect me and it takes the current organization id.

I would appreciate any help you could give me to solve this.

I remain attentive to any comments that can be made to me
