Capsule CRM SDK for Java

Unofficial Java SDK for Capsule CRM's API v2.

Features

Warning: this library is not feature complete. We have only developed the features we've needed internally. As we need more features we will add them to this library. We welcome PRs filling in new features.

What's implemented so far?

• List parties
• Filter parties by tag and type
• Update existing parties
• List tags and fields

Setup

Note: This artifact isn't published to the public Maven repo yet. Interested in using it? Please contact us by opening an issue.

Grab via Maven:

<dependency>
  <groupId>com.cropster</groupId>
  <artifactId>capsulecrm-api</artifactId>
  <version>0.1</version>
</dependency>

or Gradle:

compile 'com.cropster:capsulecrm-api:0.1'

Requirements

• Java 8
• Capsule CRM API Credentials

The SDK uses Retrofit 2 under the hood as a REST client, which uses OkHttp as the underlying http client.

Usage

Quick Start

Create an instance of the API client. It is immutable and thread safe.

final CapsuleClient capsuleClient = CapsuleClient.builder()
        .accessToken(<access token>)
        .userAgent(<user agent>)
        .logLevel(Logger.Level.FULL)
        .logger(log::info) // log can be an Slf4j or log4j logger
        .build();

See the official capsule docs to learn how to get an access token.

A client can perform various operations on different types of resources (Party, Tag, CustomField, etc). The resources are organized into modules:

capsule().parties() // retrieve the parties module

Each module contains a set of methods which can be used to perform various operations on the specified resource type.

Example: Retrieving all parties (synchronously):

List<Party> orgs = capsule()
                  .parties()
                  .all();

See the Examples section below for more examples.

Data Model

This library heavily uses the Immutable Builder pattern to handle data objects.

For example this creates a new party object with only the firstName field:

Party alice = Party.builder().firstName("Alice").build();

// Serializes to the JSON:
{
    "party":  {
        "firstName": "Alice"
    }
}

The alice object is an immutable instance of Party. This means the following does not work:

alice.setLastName("Sanchez")  // DOES NOT WORK:  there are no setters on Party

Instead all changes are performed by building a new object. If you want to give Alice a last name you must use the withLastName() method.

Party aliceSanchez = alice.withLastName("Sanchez");

// Serializes to the JSON:
{
    "party":  {
        "firstName": "Alice"
        "lastName": "Sanchez"
    }
}

If you want to transform multiple fields at once use the toBuilder() method.

Party aliceSanchezCeo = aliceSanchez.toBuilder()
                                 .jobTitle("CEO")
                                 .emailAddress(Email.builder()
                                                .address("[email protected]")
                                                .type("Work")
                                                .build())
                                 .build();

// Serializes to the JSON:
{
    "party":  {
        "firstName": "Alice"
        "lastName": "Sanchez",
        "jobTitle": "CEO",
        "emailAddresses": [
            {
              "type": "Work",
              "address": "[email protected]"
            }
      ],
    }
}

Examples

Retrieving all parties (synchronously):

List<Party> orgs = capsule()
                  .parties()
                  .all();

Retrieve all organisations with a certain tag (synchronously):

List<Party> orgs = capsule()
                  .parties()
                  .ofType(PartyType.ORGANISATION)
                  .withTag("SpecialTag")
                  .all();

Retrieve one party by id (synchronously):

List<Party> orgs = capsule()
                  .parties()
                  .one(50L);

Add a tag to party (synchronously):

Optional<Party> party = capsule()
                        .parties()
                        .add(party, Tag.builder().id(1234L).build())

Update a party (synchronously):

Just like the Capsule HTTP API, when updating a value omitted/null fields are left unchanged.

So if you want to edit the about line of a party and you know its id, then it is as as simple as:

Optional<Party> party = capsule()
                        .parties()
                        .update(Party.builder().id(50L).about("a new about line").build())
