# Apideck Java SDK Skill

## Overview

The [Apideck Unified API](https://apideck.com) provides a single integration layer to connect with 200+ third-party services across accounting, CRM, HRIS, file storage, ATS, e-commerce, and more. The official Java SDK (`com.apideck:unify`) provides typed clients for all unified APIs.

## Installation

**Gradle:**
```groovy
implementation 'com.apideck:unify:0.30.3'
```

**Maven:**
```xml
<dependency>
    <groupId>com.apideck</groupId>
    <artifactId>unify</artifactId>
    <version>0.30.3</version>
</dependency>
```

Requires JDK 11 or later.

## IMPORTANT RULES

- ALWAYS use the `com.apideck:unify` SDK. DO NOT make raw HTTP calls to the Apideck API.
- ALWAYS pass `apiKey`, `appId`, and `consumerId` when building the client.
- USE `serviceId` on requests to specify which downstream connector to use.
- USE the fluent builder pattern for constructing requests.
- ALWAYS handle errors with try/catch using `ApideckError` as the base class.
- DO NOT store API keys in source code. Use environment variables.

## Quick Start

```java
import com.apideck.unify.Apideck;
import com.apideck.unify.models.operations.*;

Apideck sdk = Apideck.builder()
    .consumerId("your-consumer-id")
    .appId("your-app-id")
    .apiKey(System.getenv("APIDECK_API_KEY"))
    .build();

sdk.crm().contacts().list()
    .serviceId("salesforce")
    .limit(20)
    .callAsStream()
    .forEach(page -> {
        page.getContactsResponse().ifPresent(res ->
            res.getData().forEach(contact ->
                System.out.println(contact.getName())
            )
        );
    });
```

## SDK Patterns

### Client Setup

```java
import com.apideck.unify.Apideck;

Apideck sdk = Apideck.builder()
    .consumerId("your-consumer-id")
    .appId("your-app-id")
    .apiKey(System.getenv("APIDECK_API_KEY"))
    .build();
```

Async client:

```java
import com.apideck.unify.AsyncApideck;

AsyncApideck asyncSdk = Apideck.builder()
    .consumerId("your-consumer-id")
    .appId("your-app-id")
    .apiKey(System.getenv("APIDECK_API_KEY"))
    .build()
    .async();
```

### CRUD Operations

Uses a fluent builder pattern: `sdk.{category}().{resource}().{operation}()`.

```java
import com.apideck.unify.models.components.*;
import com.apideck.unify.models.operations.*;

// LIST
sdk.crm().contacts().list()
    .serviceId("salesforce")
    .limit(20)
    .filter(ContactsFilter.builder().email("john@example.com").build())
    .sort(ContactsSort.builder()
        .by(ContactsSortBy.UPDATED_AT)
        .direction(SortDirection.DESC)
        .build())
    .call();

// CREATE
sdk.crm().contacts().create()
    .serviceId("salesforce")
    .contact(ContactInput.builder()
        .firstName("John")
        .lastName("Doe")
        .emails(List.of(Email.builder()
            .email("john@example.com")
            .type(EmailType.PRIMARY)
            .build()))
        .phoneNumbers(List.of(PhoneNumber.builder()
            .number("+1234567890")
            .type(PhoneNumberType.MOBILE)
            .build()))
        .build())
    .call();

// GET
sdk.crm().contacts().get()
    .id("contact_123")
    .serviceId("salesforce")
    .call();

// UPDATE
sdk.crm().contacts().update()
    .id("contact_123")
    .serviceId("salesforce")
    .contact(ContactInput.builder().firstName("Jane").build())
    .call();

// DELETE
sdk.crm().contacts().delete()
    .id("contact_123")
    .serviceId("salesforce")
    .call();
```

### Pagination

Multiple approaches available:

```java
// Stream (recommended)
sdk.accounting().invoices().list()
    .serviceId("quickbooks")
    .limit(50)
    .callAsStream()
    .forEach(page -> {
        // handle page
    });

// Iterable
for (var page : sdk.accounting().invoices().list()
    .serviceId("quickbooks")
    .limit(50)
    .callAsIterable()) {
    // handle page
}

// Reactive Streams (for Project Reactor, RxJava, etc.)
var publisher = sdk.accounting().invoices().list()
    .serviceId("quickbooks")
    .limit(50)
    .callAsPublisher();
```

### Async Support

Returns `CompletableFuture<T>` for standard operations:

```java
AsyncApideck asyncSdk = sdk.async();

asyncSdk.crm().contacts().list()
    .serviceId("salesforce")
    .limit(20)
    .call()
    .thenAccept(res -> {
        // handle response
    });
```

### Error Handling

```java
import com.apideck.unify.models.errors.*;

try {
    sdk.crm().contacts().get()
        .id("invalid")
        .serviceId("salesforce")
        .call();
} catch (BadRequestResponse e) {
    System.err.println("Bad request: " + e.message());
} catch (UnauthorizedResponse e) {
    System.err.println("Invalid API key");
} catch (NotFoundResponse e) {
    System.err.println("Record not found");
} catch (PaymentRequiredResponse e) {
    System.err.println("API limit reached");
} catch (UnprocessableResponse e) {
    System.err.println("Validation error: " + e.message());
} catch (ApideckError e) {
    System.err.println("API error " + e.code() + ": " + e.message());
}
```

### Retry Configuration

```java
import com.apideck.unify.utils.BackoffStrategy;
import com.apideck.unify.utils.RetryConfig;
import java.util.concurrent.TimeUnit;

Apideck sdk = Apideck.builder()
    .retryConfig(RetryConfig.builder()
        .backoff(BackoffStrategy.builder()
            .initialInterval(1L, TimeUnit.MILLISECONDS)
            .maxInterval(50L, TimeUnit.MILLISECONDS)
            .maxElapsedTime(1000L, TimeUnit.MILLISECONDS)
            .baseFactor(1.1)
            .jitterFactor(0.15)
            .retryConnectError(false)
            .build())
        .build())
    .consumerId("your-consumer-id")
    .appId("your-app-id")
    .apiKey(System.getenv("APIDECK_API_KEY"))
    .build();
```
