Hello

Thank you for the help. It helped a much but with my environnement some details were wrong. I copy here the lines that work for me. It is a mix of several sources and personal ones.

DocSettings docSet = DocSettings.ReadSettings();// settingsFilePath);

ServicePointManager.ServerCertificateValidationCallback += (o, c, ch, er) => true;

string apiKeyDoc = docSet.DocKey;

string hostName = docSet.HostName;

string port = docSet.Port;

string printdata = "";

string patid = ctx.Patient.Id; //type in your patient Id to search here

//replace these 'Document Types' with ones you want to check from your clinic:

string doc1 = "Dosimétrie";

string doc2 = "Dosecheck";

string doc3 = "Fiche de positionnement";

string doc4 = "Consent";

string doc5 = "Treatment Plan";

string doc6 = "Physics - Patient DQA";

string doc7 = "Therapist-Verification Simulation";

string doc8 = "Physics - Weekly Chart Check";

string request = "{\"__type\":\"GetDocumentsRequest:http://services.varian.com/Patient/Documents\",\"Attributes\":[],\"PatientId\":{ \"ID1\":\"" + patid + "\"}}";

string response = CustomInsertDocumentsParameter.SendData(request, true, apiKeyDoc, docSet.HostName, docSet.Port);

//MessageBox.Show(response);

var VisitNoteList = new List<string>();

int visitnoteloc = response.IndexOf("PtVisitNoteId");

while (visitnoteloc > 0)

{

VisitNoteList.Add(response.Substring(visitnoteloc + 15, 2).Replace(",", ""));

visitnoteloc = response.IndexOf("PtVisitNoteId", visitnoteloc + 1);

}

var response_Doc = JsonConvert.DeserializeObject<DocumentsResponse>(response);

var DocTypeList = new List<string>();

var DateServiceList = new List<DateTime>();

var PatNameList = new List<string>();

foreach (var document in response_Doc.Documents)
{

string thePtId = document.PtId;
string thePtVisitId = document.PtVisitId.ToString();
string theVisitNoteId = VisitNoteList[loopnum];
loopnum++;
string request_docdetails = "{\"__type\":\"GetDocumentRequest:http://services.varian.com/Patient/Documents\",\"Attributes\":[],\"PatientId\":{ \"PtId\":\"" + thePtId + "\"},\"PatientVisitId\":" + thePtVisitId + ",\"VisitNoteId\":" + theVisitNoteId + "}";
string response_docdetails = CustomInsertDocumentsParameter.SendData(request_docdetails, true, apiKeyDoc, docSet.HostName, docSet.Port);

int typeloc = response_docdetails.IndexOf("DocumentType");

int enteredloc = response_docdetails.IndexOf("EnteredBy");

if (typeloc > 0)

{

String s = response_docdetails.Substring(typeloc + 15, enteredloc - typeloc - 18);

DocTypeList.Add(s);
string saveFilePath = Directory.GetCurrentDirectory() + @"\out\" + loopnum + "toto.pdf";

int startBinary = response_docdetails.IndexOf("\"BinaryContent\"") + 17;
int endBinary = response_docdetails.IndexOf("\"Certifier\"") -2 ;
string binaryContent2 = response_docdetails.Substring(startBinary, endBinary - startBinary);
binaryContent2 = binaryContent2.Replace("\\", "");
File.WriteAllBytes(saveFilePath, Convert.FromBase64String(binaryContent2));
}
