Medplum CRUD Operations with REST APIs: A Lazy Person’s Guide

Quick guide to effortlessly perform Medplum CRUD operations using REST APIs, including implementing FHIR for healthcare data exchange.

Here I'll be talking about implementing CRUD (Create, Read, Update,Delete) operations on medplum server after successfully implementing it

---

Here, I've hosted my backend in my server, so I'll be explaining to you how I'm doing the CRUD operation on that hosted server, if you want to install Medplum on your local setup, please go through the Medplum documentation

To start with, first, we need to Register an account on Medplum.if you're using the application locally you can register it in localhost or go forward with the Medplum site.

You can use these credentials which are offered by Medplum itself

The default username is admin at example.com default password medplum_admin.

After that, create a project in Medplum, and create a Client Application, you can create a client application by going to the /admin/clients route your app.(if you're using localhost the route will look something like http://localhost:3000/admin/client)

If you want to check whether your backend is working, you can go to the route "yourbackendurl/healthcheck"(if your backend URL is api.medplum.com, go to api.medplum.com/healthcheck)

CRUD Operations

Create: POST

To create a new patient using the FHIR standards

http://localhost:8000/patient or your_hosted_backend_link/patient

Content-Type: application/fhir+json
Authorisation: Beared ACCESS_TOKEN

{
 "resourceType": "Patient",
 "identifier": [ { "system": "urn:oid:1.2.36.146.595.217.0.1", "value": "12345" } ],
 "name": [ {
 "family": "Miller",
 "given": [ "John", "Doe" ]
 } ],
 "gender": "male",
 "birthDate": "1964-12-15"
}

You can refer to this link to know how to get the ACCESS_TOKEN for the REST APIs

Read : GET

To read all the patients

http://localhost:8000/Patient

To read a single patient

http://localhost:8000/Patient/123

Update: UPDATE

To update a patient whose id is 123

http://localhost:8000/Patient/123

{
 "resourceType": "Patient",
 "id": "123",
 "identifier": [ { "system": "urn:oid:1.2.36.146.595.217.0.1", "value": "12345" } ],
 "name": [ {
 "family": "Miller",
 "given": [ "John", "Doe" ]
 } ],
 "gender": "male",
 "birthDate": "1964-12-15"
 "address": [ {
 "line": [ "Address line" ],
 "city": "any city",
 "state": "Random state",
 "postalCode": "5000"
 } ]
}

Delete: DELETE

To Delete a patient with ID 123

http://localhost:8000/Patient/123

That's it! With these simple examples, you can perform CRUD operations in Medplum using REST APIs. Lazy, but effective!
