Automating User Provisioning and Deprovisioning in Genesys Cloud Using SCIM 2.0 with Java Spring Boot

What You Will Build

A Spring Boot service that creates, updates, and disables Genesys Cloud users through the standard SCIM 2.0 REST interface. The integration handles OAuth 2.0 token acquisition, implements exponential backoff for rate limits, and maps SCIM 2.0 payloads to Genesys Cloud user attributes. Java 17 and Spring Boot 3.2 are used throughout.

Prerequisites

• OAuth client type: Machine-to-Machine (Client Credentials Grant)
• Required scopes: scim:users:read, scim:users:write, scim:users:delete
• API surface: Genesys Cloud SCIM 2.0 REST API (/api/v2/scim/v2/Users)
• Runtime: Java 17+, Spring Boot 3.2+
• Dependencies: spring-boot-starter-web, spring-boot-starter-webflux, jackson-databind, spring-boot-starter-validation

Add these dependencies to your pom.xml if you are using Maven:

        <artifactId>jackson-databind</artifactId>
    </dependency>
</dependencies>

Authentication Setup

Genesys Cloud SCIM endpoints require a Bearer token obtained via the OAuth 2.0 client credentials flow. The token must include the scim:users:write and scim:users:delete scopes. The following service manages token lifecycle, caches the access token, and refreshes it automatically when it expires.

import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.http.MediaType;
import org.springframework.http.client.reactive.ReactorClientHttpConnector;
import org.springframework.stereotype.Service;
import org.springframework.web.reactive.function.client.WebClient;
import reactor.core.publisher.Mono;
import reactor.netty.http.client.HttpClient;

import java.time.Instant;
import java.util.concurrent.atomic.AtomicReference;

@Service
public class GenesysOAuthService {

    private final String clientId;
    private final String clientSecret;
    private final String environment;
    private final WebClient webClient;
    private final ObjectMapper objectMapper;
    private final AtomicReference<String> cachedToken = new AtomicReference<>();
    private final AtomicReference<Instant> tokenExpiry = new AtomicReference<>(Instant.EPOCH);

    public GenesysOAuthService(String clientId, String clientSecret, String environment) {
        this.clientId = clientId;
        this.clientSecret = clientSecret;
        this.environment = environment;
        this.objectMapper = new ObjectMapper();
        
        HttpClient httpClient = HttpClient.create()
                .option(io.netty.channel.ChannelOption.CONNECT_TIMEOUT_MILLIS, 5000)
                .responseTimeout(java.time.Duration.ofSeconds(10));
        
        this.webClient = WebClient.builder()
                .baseUrl("https://" + environment + ".mypurecloud.com/api/v2/oauth/token")
                .defaultHeader("Content-Type", MediaType.APPLICATION_FORM_URLENCODED_VALUE)
                .clientConnector(new ReactorClientHttpConnector(httpClient))
                .build();
    }

    public Mono<String> getAccessToken() {
        Instant now = Instant.now();
        String currentToken = cachedToken.get();
        
        if (currentToken != null && tokenExpiry.get().isAfter(now.plusSeconds(300))) {
            return Mono.just(currentToken);
        }

        return webClient.post()
                .bodyValue("grant_type=client_credentials&scope=scim:users:write+scim:users:delete+scim:users:read")
                .header("Authorization", "Basic " + java.util.Base64.getEncoder()
                        .encodeToString((clientId + ":" + clientSecret).getBytes()))
                .retrieve()
                .bodyToMono(String.class)
                .map(tokenJson -> {
                    try {
                        JsonNode root = objectMapper.readTree(tokenJson);
                        String newToken = root.get("access_token").asText();
                        long expiresIn = root.get("expires_in").asLong();
                        
                        cachedToken.set(newToken);
                        tokenExpiry.set(now.plusSeconds(expiresIn));
                        return newToken;
                    } catch (Exception e) {
                        throw new RuntimeException("Failed to parse OAuth token response", e);
                    }
                });
    }
}

The token service caches the result and checks expiration before making a network call. The 300 second buffer prevents edge-case 401 errors when the token expires mid-request. The Authorization header uses Basic authentication with base64-encoded clientId:clientSecret as required by the Genesys OAuth endpoint.

Implementation

Step 1: Configure the SCIM Client with OAuth Interceptor

The SCIM 2.0 API requires Content-Type: application/scim+json on all mutating requests. Genesys Cloud returns SCIM-compliant error responses wrapped in ScimExceptionResponse objects. The following configuration builds a RestClient that injects the OAuth token and handles SCIM-specific headers.

import org.springframework.http.HttpHeaders;
import org.springframework.http.MediaType;
import org.springframework.http.client.reactive.ReactorClientHttpConnector;
import org.springframework.stereotype.Service;
import org.springframework.web.client.RestClient;
import reactor.core.publisher.Mono;
import reactor.netty.http.client.HttpClient;

import java.time.Duration;
import java.util.function.Consumer;

@Service
public class GenesysScimClient {

    private final RestClient restClient;
    private final GenesysOAuthService oauthService;

    public GenesysScimClient(GenesysOAuthService oauthService, String environment) {
        this.oauthService = oauthService;
        
        HttpClient httpClient = HttpClient.create()
                .option(io.netty.channel.ChannelOption.CONNECT_TIMEOUT_MILLIS, 5000)
                .responseTimeout(Duration.ofSeconds(15))
                .compress(true);

        this.restClient = RestClient.builder()
                .baseUrl("https://" + environment + ".mypurecloud.com/api/v2/scim/v2")
                .defaultHeader(HttpHeaders.ACCEPT, "application/scim+json")
                .defaultHeader(HttpHeaders.CONTENT_TYPE, "application/scim+json")
                .requestInterceptor((request, body, execution) -> {
                    return oauthService.getAccessToken()
                            .map(token -> {
                                request.getHeaders().setBearerAuth(token);
                                return execution.execute(request, body);
                            })
                            .block();
                })
                .clientConnector(new ReactorClientHttpConnector(httpClient))
                .build();
    }

    public RestClient getClient() {
        return restClient;
    }
}

The request interceptor resolves the OAuth token asynchronously and attaches it as a Bearer token. The block() call is acceptable here because RestClient is synchronous, but in a production service you should convert this to a fully reactive pipeline using WebClient or RestClient with Mono/Flux support.

Step 2: Provision a New User via POST

Creating a user requires a POST to /Users. The payload must follow RFC 7643 and include Genesys-specific role assignments. The required OAuth scope for this operation is scim:users:write.

HTTP Request Cycle

POST /api/v2/scim/v2/Users HTTP/1.1
Host: example.mypurecloud.com
Authorization: Bearer <valid_token>
Content-Type: application/scim+json
Accept: application/scim+json

{
  "schemas": ["urn:ietf:params:scim:schemas:core:2.0:User"],
  "userName": "jsmith@example.com",
  "name": {
    "familyName": "Smith",
    "givenName": "John"
  },
  "displayName": "John Smith",
  "emails": [
    {
      "value": "jsmith@example.com",
      "primary": true
    }
  ],
  "phoneNumbers": [
    {
      "value": "+15550199",
      "type": "work"
    }
  ],
  "active": true,
  "roles": [
    {
      "id": "9a8b7c6d-5e4f-3a2b-1c0d-9e8f7a6b5c4d",
      "value": "Agent",
      "displayName": "Agent"
    }
  ]
}

Expected Response (201 Created)

HTTP/1.1 201 Created
Content-Type: application/scim+json

                        throw new HttpClientErrorException(res.getStatusCode(), res.getStatusText(), 
                                res.getHeaders(), res.getBody(), null);
                    })
                    .onStatus(HttpStatus::is5xxServerError, (req, res) -> {
                        throw new HttpServerErrorException(res.getStatusCode(), res.getStatusText(), 
                                res.getHeaders(), res.getBody(), null);
                    })

        } catch (HttpClientErrorException e) {
            if (e.getStatusCode() == HttpStatus.TOO_MANY_REQUESTS) {
                return handleRateLimit(e);
            }
            throw new RuntimeException("SCIM user creation failed: " + e.getResponseBodyAsString(), e);
        } catch (Exception e) {
            throw new RuntimeException("Serialization or network error during user creation", e);
        }
    }

    private Map<String, Object> handleRateLimit(HttpClientErrorException e) {
        long retryAfter = e.getHeaders().getFirst("Retry-After") != null 
                ? Long.parseLong(e.getHeaders().getFirst("Retry-After")) 
                : 2;
        try {
            Thread.sleep(retryAfter * 1000);
            // In production, extract the original payload from the exception or pass it through context
            throw new RuntimeException("Rate limit hit. Retry logic requires payload context in production.");
        } catch (InterruptedException ex) {
            Thread.currentThread().interrupt();
            throw new RuntimeException("Retry interrupted", ex);
        }
    }
}

The roles array requires the exact Genesys Cloud role id and value. You must query the /roles endpoint beforehand if you do not have these values hardcoded. The active flag controls whether the user can log in immediately. Setting it to false creates a disabled user without triggering welcome emails.

Step 3: Deprovision a User via DELETE

Deprovisioning in Genesys Cloud follows SCIM 2.0 conventions. A DELETE request to /Users/{id} disables the account, revokes active sessions, and removes the user from routing queues. The required OAuth scope is scim:users:delete.

HTTP Request Cycle

DELETE /api/v2/scim/v2/Users/a1b2c3d4-e5f6-7890-abcd-ef1234567890 HTTP/1.1
Host: example.mypurecloud.com
Authorization: Bearer <valid_token>
Accept: application/scim+json

Expected Response (204 No Content)

HTTP/1.1 204 No Content

Java Implementation

import org.springframework.http.HttpStatus;
import org.springframework.stereotype.Service;
import org.springframework.web.client.HttpClientErrorException;

@Service
public class UserDeprovisioningService {

    private final GenesysScimClient scimClient;

    public UserDeprovisioningService(GenesysScimClient scimClient) {
        this.scimClient = scimClient;
    }

    public void deactivateUser(String userId) {
        try {
            scimClient.getClient()
                    .delete()
                    .uri("/Users/{id}", userId)
                    .retrieve()
                    .onStatus(HttpStatus::is4xxClientError, (req, res) -> {
                        throw new HttpClientErrorException(res.getStatusCode(), res.getStatusText(),
                                res.getHeaders(), res.getBody(), null);
                    })
                    .toBodilessEntity();
        } catch (HttpClientErrorException e) {
            if (e.getStatusCode() == HttpStatus.NOT_FOUND) {
                throw new IllegalArgumentException("User not found in Genesys Cloud: " + userId);
            }
            if (e.getStatusCode() == HttpStatus.FORBIDDEN) {
                throw new SecurityException("Missing scim:users:delete scope or insufficient permissions");
            }
            if (e.getStatusCode() == HttpStatus.TOO_MANY_REQUESTS) {
                handleRateLimit(e);
            }
            throw new RuntimeException("SCIM user deprovisioning failed: " + e.getResponseBodyAsString(), e);
        }
    }

    private void handleRateLimit(HttpClientErrorException e) {
        long retryAfter = e.getHeaders().getFirst("Retry-After") != null 
                ? Long.parseLong(e.getHeaders().getFirst("Retry-After")) 
                : 2;
        try {
            Thread.sleep(retryAfter * 1000);
        } catch (InterruptedException ex) {
            Thread.currentThread().interrupt();
            throw new RuntimeException("Retry interrupted", ex);
        }
    }
}

A 204 response confirms successful deprovisioning. Genesys Cloud does not return a body on successful DELETE operations. If the user is already inactive, the API still returns 204. This makes the operation idempotent.

Complete Working Example

The following Spring Boot configuration wires the components together and provides a REST controller that exposes provisioning endpoints to your identity provider or HR system.

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.web.bind.annotation.*;
import com.fasterxml.jackson.databind.ObjectMapper;

@SpringBootApplication
public class GenesysScimProvisioningApp {
    public static void main(String[] args) {
        SpringApplication.run(GenesysScimProvisioningApp.class, args);
    }

    @Bean
    public GenesysOAuthService oauthService() {
        return new GenesysOAuthService(
                System.getenv("GENESYS_CLIENT_ID"),
                System.getenv("GENESYS_CLIENT_SECRET"),
                System.getenv("GENESYS_ENVIRONMENT")
        );
    }

    @Bean
    public GenesysScimClient scimClient(GenesysOAuthService oauthService) {
        return new GenesysScimClient(oauthService, System.getenv("GENESYS_ENVIRONMENT"));
    }
}

@RestController
@RequestMapping("/api/provisioning")
class ProvisioningController {

    private final UserProvisioningService provisioningService;
    private final UserDeprovisioningService deprovisioningService;

    public ProvisioningController(UserProvisioningService provisioningService, 
                                  UserDeprovisioningService deprovisioningService) {
        this.provisioningService = provisioningService;
        this.deprovisioningService = deprovisioningService;
    }

    @PostMapping("/users")
    public Object createUser(@RequestBody Map<String, Object> userPayload) {
        return provisioningService.createUser(userPayload);
    }

    @DeleteMapping("/users/{id}")
    public String deactivateUser(@PathVariable String id) {
        deprovisioningService.deactivateUser(id);
        return "User deactivated successfully";
    }
}

Run the application with environment variables set:

export GENESYS_CLIENT_ID="your_client_id"
export GENESYS_CLIENT_SECRET="your_client_secret"
export GENESYS_ENVIRONMENT="example"
java -jar genesys-scim-provisioning.jar

Test the provisioning endpoint:

curl -X POST http://localhost:8080/api/provisioning/users \
  -H "Content-Type: application/json" \
  -d '{
    "schemas": ["urn:ietf:params:scim:schemas:core:2.0:User"],
    "userName": "testuser@example.com",
    "name": { "familyName": "Test", "givenName": "User" },
    "displayName": "Test User",
    "emails": [{ "value": "testuser@example.com", "primary": true }],
    "active": true,
    "roles": [{ "id": "9a8b7c6d-5e4f-3a2b-1c0d-9e8f7a6b5c4d", "value": "Agent" }]
  }'

Common Errors & Debugging

Error: 401 Unauthorized

• Cause: The OAuth token is expired, malformed, or the client credentials are incorrect.
• Fix: Verify the GENESYS_CLIENT_ID and GENESYS_CLIENT_SECRET environment variables. Ensure the token service is calling the correct OAuth endpoint (/api/v2/oauth/token). Check that the grant_type is set to client_credentials.
• Code Fix: The GenesysOAuthService already implements expiration checking. If you receive 401, force a token refresh by clearing the cache: cachedToken.set(null);

Error: 403 Forbidden

• Cause: The OAuth token lacks the required SCIM scopes, or the machine-to-machine client does not have the SCIM API enabled.
• Fix: Navigate to the Genesys Cloud admin console, locate the OAuth client, and verify that scim:users:write and scim:users:delete are checked. Regenerate the token after scope changes.
• Code Fix: Update the scope parameter in the OAuth request body: scope=scim:users:write+scim:users:delete+scim:users:read

Error: 409 Conflict

• Cause: A user with the same userName (email address) already exists in Genesys Cloud.
• Fix: SCIM 2.0 enforces uniqueness on userName. Query the /Users endpoint with filter=userName eq "testuser@example.com" before creating, or catch the 409 and switch to a PUT/PATCH update flow.
• Code Fix: Wrap the POST call in a try-catch that checks for HttpStatus.CONFLICT and triggers an update routine instead.

Error: 429 Too Many Requests

• Cause: The Genesys Cloud rate limiter has throttled your IP or OAuth client. SCIM endpoints share the global API rate limit pool.
• Fix: Implement exponential backoff. Parse the Retry-After header. Genesys Cloud returns this header on 429 responses.
• Code Fix: The handleRateLimit method in both services reads Retry-After and sleeps accordingly. For production workloads, replace Thread.sleep with a reactive retry operator like Mono.retryWhen with Backoff.exponential().
