How to get the list of potentially matching document IDs?

Issue:

I need to get the IDs of all potentially matching documents after reading the sample.

Solution:

After receiving the results of your scan, the system automatically generates a response containing the IDs of the most suitable documents (candidates) in the passport database in our IRS.

Example

Processing the Germany - Passport (2004) Child document.

You will receive:

"FDSIDList": {
 "Count": 3, // number of candidates
 "ICAOCode": "D<<",
 "List": [ // list of candidates
  10878,
  2979,
  15585
  ],

You should take a list of candidates from the processing results and paste it in the FDSIDList:

struct TShowImageData{
 char CountryCode[4];  // three letters country code
int32_t  DocumentType;   // 0 - not defined, 1 - Passport, 2 - AutoDocs, 3 - Currency, 4 - Visas
int32_t  DocumentVersion; // 0 - not defined, 1 - First Document, 2 - Second, ...
int32_t  Illumination;   // 0 - not defined, 1 - Normal Light, 2 - UV 365, 4 - IR 870
int32_t  PageType;     // 0 - not defined, 1 - Cover, 2 - Owner's data, ...
union {
  TFDSIDList *DocIDList;
 char *TextList;
 };
};

By using this method, you are more likely to obtain the most probable candidates rather than just manually selecting them based on their Passport value:
