Dr. Chrono API Integration With Salesforce™

import requests

response = requests.get(‘https://drchrono.com/api/users/current’, headers={
   ‘Authorization’: ‘Bearer %s’ % access_token,
})
response.raise_for_status()
data = response.json()

# You can store this in your database along with the tokens
username = data[‘username’]

This is what we used to integrate it in Salesforce™. The next step which we require is to push the data from both sides or simply we can say a two-way integration between Salesforce™ and Dr.Chrono.

So basically we did is a two-way synchronization of Patient and Appointment but for Doctor’s list, we can only sync it from their end. For synchronization, we are using an external Id for each object and on the bases of this external Id we were doing Upsert and insert from both side. For Salesforce™ it is working as an external Id but at their end, it was treated as Id which helps us a lot in reducing the duplicity of records.

Connectivity of Dr.Chrono API with Salesforce™ :

HttpRequest req = new HttpRequest();

               HttpResponse res = new HttpResponse();

               Http http = new Http();

               String Endpoint = ‘/o/token/’;

               req.setEndpoint(BaseUrl + Endpoint);

               req.setBody(BodyString);

               req.setTimeOut(120000);

               system.debug(‘>>>>>Request –>’+req.getBody());

               res = http.send(req);

               system.debug(‘>>>>>Status Code –>’+res.getStatusCode());

               if(res.getStatusCode() != NULL && res.getStatusCode() == 200 && res.getBody() != NULL){

                   System.debug(‘–>>RESPONSE in RefreshAccessToken –> ‘+res.getBody());

                   JSONParser parser = JSON.createParser(res.getBody());

                   while(parser.nextToken() != null) {

                       if(parser.getCurrentToken() == JSONToken.FIELD_NAME && parser.getText() == ‘access_token’) {

                           parser.nextToken();

                           accessToken = parser.getText();

                           customsetting.chrono__Access_Token__c = accessToken;

                           parser.nextToken();

    try{

                               Integer secondsValue = parser.getIntegervalue() – 3600;

                               customsetting.chrono__Token_Expires_On__c = DateTime.now().addSeconds(secondsValue);

                           } catch (Exception e){
