well done @jecihjoy ,
will you implement other Operations like Update ,Search etc in a different PR ??

[sherrif10]

This can however be merged to free this PR , And it will leverage code workflow and tracking, Am thinking since this is the initial implementation it would be more clear to track different changes that may come along, cc @mozzy11 we also need to track mappings for appointmentResources FYI cc @ibacher @mozzy11

Hello @sherrif10
There was a decision made in one of the FHIR squad meetings, suggesting this kind of implementation be implemented in the dependant module i.e this code should be moved to bahmni appointments module. Oh! forgot there's already a PR for this here. Perhaps, we should be closing this PR.

@corneliouzbett , Thanks for the updates will follow up with the pr you shared
