Merge Java Library

The Merge Java SDK provides convenient access to the Merge API from Java or Kotlin.

Documentation

API documentation is available at here.

Installation

Gradle

Add the dependency in your build.gradle:

dependencies {
    implementation 'dev.merge:merge-java-client:0.x.x'
}

Maven

Add the dependency in your pom.xml:

<dependency>
    <groupId>dev.merge</groupId>
    <artifactId>merge-java-client</artifactId>
    <version>0.x.x</version>
</dependency>

Instantiation

MergeApiClient mergeClient = MergeApiClient.builder()
    .accountToken("ACCOUNT_TOKEN")
    .apiKey("API_KEY")
    .build();

Request Options

Every endpoint has an overloaded equivalent which takes RequestOptions that allow you to override the account token and api key.

import com.merge.api.MergeApiClient;
import com.merge.api.resources.ats.types.Candidate;
import com.merge.api.resources.ats.candidates.requests.CandidatesRetrieveRequest;
import com.merge.api.core.RequestOptions;

MergeApiClient mergeClient = MergeApiClient.builder()
    .accountToken("ACCOUNT_TOKEN")
    .apiKey("API_KEY")
    .build();

Candidate candidate = mergeClient.ats().candidates().retrieve(
    "<CANDIDATE_UUID>", 
    CandidatesRetrieveRequest.builder()
            .includeRemoteData(true)
            .build(), 
    RequestOptions.builder()
        .accountToken("OVERRIDE_ACCOUNT_TOKEN")
        .build());

Usage

Below are code snippets of how you can use the Java SDK.

Create Link Token

import com.merge.api.MergeApiClient;
import com.merge.api.resources.ats.types.CategoriesEnum;
import com.merge.api.resources.ats.types.LinkToken;
import com.merge.api.resources.ats.linktoken.requests.EndUserDetailsRequest;

import java.util.List;

MergeApiClient mergeClient = MergeApiClient.builder()
    .accountToken("ACCOUNT_TOKEN")
    .apiKey("API_KEY")
    .build();

LinkToken linkToken = mergeClient.ats().linkToken().create(EndUserDetailsRequest.builder()
    .endUserEmailAddress("[email protected]")
    .endUserOrganizationName("acme")
    .endUserOriginId("1234")
    .categories(List.of(CategoriesEnum.ATS))
    .build());

System.out.println("Created link token", linkToken.getLinkToken())

Get Employee

import com.merge.api.MergeApiClient;
import com.merge.api.resources.hris.employees.requests.EmployeesRetrieveRequest;
import com.merge.api.resources.hris.types.Employee;

MergeApiClient mergeClient = MergeApiClient.builder()
    .accountToken("ACCOUNT_TOKEN")
    .apiKey("API_KEY")
    .build();

Employee employee = mergeClient.hris().employees().retrieve(
    "0958cbc6-6040-430a-848e-aafacbadf4ae",
    EmployeesRetrieveRequest.builder()
        .includeRemoteData(true)
        .build());

Get Candidate

import com.merge.api.MergeApiClient;
import com.merge.api.resources.ats.types.Candidate;
import com.merge.api.resources.ats.candidates.requests.CandidatesRetrieveRequest;

MergeApiClient mergeClient = MergeApiClient.builder()
    .accountToken("ACCOUNT_TOKEN")
    .apiKey("API_KEY")
    .build();

Candidate candidate = mergeClient.ats().candidates().retrieve(
    "521b18c2-4d01-4297-b451-19858d07c133", 
    CandidatesRetrieveRequest.builder()
        .includeRemoteData(true)
        .build());

Filter Candidate

import com.merge.api.MergeApiClient;
import com.merge.api.resources.ats.candidates.requests.CandidatesListRequest;
import com.merge.api.resources.ats.types.PaginatedCandidateList;

import java.time.OffsetDateTime;

MergeApiClient mergeClient = MergeApiClient.builder()
    .accountToken("ACCOUNT_TOKEN")
    .apiKey("API_KEY")
    .build();
    
PaginatedCandidateList candidate = mergeClient.ats().candidates().list(
    CandidatesListRequest.builder()
        .createdAfter(OffsetDateTime.parse("2007-12-03T10:15:30+01:00"))
        .build());

Get Contact

import com.merge.api.MergeApiClient;
import com.merge.api.resources.accounting.contacts.requests.ContactsRetrieveRequest;
import com.merge.api.resources.accounting.types.Contact;

MergeApiClient mergeClient = MergeApiClient.builder()
    .accountToken("ACCOUNT_TOKEN")
    .apiKey("API_KEY")
    .build();

Contact contact = mergeClient.accounting().contacts().retrieve(
    "c640b80b-fac9-409f-aa19-1f9221aec445", 
    ContactsRetrieveRequest.builder()
        .includeRemoteData(true)
        .build());

Create Ticket

import com.merge.api.MergeApiClient;
import com.merge.api.resources.ticketing.tickets.requests.TicketEndpointRequest;
import com.merge.api.resources.ticketing.types.TicketRequest;
import com.merge.api.resources.ticketing.types.TicketRequestStatus;
import com.merge.api.resources.ticketing.types.TicketStatusEnum;
import java.time.OffsetDateTime;

MergeApiClient mergeClient = MergeApiClient.builder()
    .accountToken("ACCOUNT_TOKEN")
    .apiKey("API_KEY")
    .build();

mergeClient.ticketing().tickets().create(TicketEndpointRequest.builder()
    .model(TicketRequest.builder()
        .name("Please add more integrations")
        .creator("3fa85f64-5717-4562-b3fc-2c963f66afa6")
        .dueDate(OffsetDateTime.parse("2022-10-11T00:00:00Z"))
        .status(TicketRequestStatus.of(TicketStatusEnum.CLOSED))
        .build())
    .build());

File Download

import com.merge.api.MergeApiClient;
import com.merge.api.resources.filestorage.types.PaginatedFileList;
import com.merge.api.resources.filestorage.files.requests.FilesListRequest;
import com.merge.api.resources.filestorage.types.File;

import java.io.InputStream;
import java.io.OutputStream;
import java.io.FileOutputStream;
import java.io.IOException;

MergeApiClient mergeClient = MergeApiClient.builder()
        .accountToken("ACCOUNT_TOKEN")
        .apiKey("API_KEY")
        .build();

PaginatedFileList fileResponse = mergeClient.filestorage().files().list(FilesListRequest.builder()
        .name("<FILE_NAME>")
        .build());

File file = fileResponse.getResults().get().get(0);
String fileId = file.getId().get();
InputStream fileContents = mergeClient.filestorage().files().downloadRetrieve(fileId);
byte[] buffer = new byte[1024]; // Set the buffer size to your desired value
try (OutputStream outputStream = new FileOutputStream("/path/to/file")) {
    int bytesRead;
    while ((bytesRead = fileContents.read(buffer)) != -1) {
        outputStream.write(buffer, 0, bytesRead);
    }
} catch (IOException e) {
    throw new RuntimeException(e);
}

Staged Builders

The generated builders all follow the staged builder pattern. Read more here.

Staged builders only allow you to build the object once all required properties have been specified. For example, to build an ApplicationEndpointRequest the Merge SDK will require that you specify the model and remoteUserId properties.

Contributing

While we value open-source contributions to this SDK, this library is generated programmatically. Additions made directly to this library would have to be moved over to our generation code, otherwise they would be overwritten upon the next generated release. Feel free to open a PR as a proof of concept, but know that we will not be able to merge it as-is. We suggest opening an issue first to discuss with us!

On the other hand, contributions to the README are always very welcome!
