SOAP & REST APIs’ History & Examples

SOAP APIs:

1. Origin in the Late 1990s: Simple Object Access Protocol (SOAP) started in the late 1990s. It helped businesses move structured data across corporate networks.

2. Standardization of Messaging: SOAP defined strict rules. These include the Envelope, Encoding, Requests, and Responses. It ensured every message followed a clear structure.

3. XML-Based Communication: SOAP uses Extensible Markup Language (XML). It supports complex, structured data formats.

4. Protocol Flexibility: SOAP works over HTTP, SMTP, and other network protocols. It allows it to run in different environments.

5. Enterprise Adoption: Large systems rely on SOAP APIs. Enterprises use them in ERP, CRM, and banking applications. They choose SOAP for reliability and strong data control.

REST APIs:

1. Creation in 2000 by Roy Fielding: Representational State Transfer (REST) started in 2000. Roy Fielding created it to simplify data exchange between web systems.

2. Simplified Developer Experience: REST removed the complexity of SOAP. It uses clean URLs and standard HTTP methods like GET, POST, PUT, and DELETE.

3. eBay and Amazon Adoption (2002): In 2002, eBay launched a REST API. Amazon followed the same year. It allowed websites to connect and share data.

4. Social Media Integration Boom (2004–2006): Flickr released its REST API in 2004. Facebook and Twitter followed in 2006. Developers used these APIs to embed and share content.

5. Modern Web Development: Today, developers use REST APIs to build websites and apps. Tools like Postman help them test and share API calls faster.

Basic of Magento REST API for a Magento Developer

1. Setting Up Your Environment

• Install the required tools.

• Use Postman or a similar API client.

• Use a JSON formatter to format responses.

• Get the required authentication credentials.

2. Understanding Endpoint Structure

Magento REST endpoints follow this pattern:
http(s)://<magento-host>/rest/<store-code>/<API-type>/<resource-path>

• <store-code> is the store view code. Use "all" for admin.

• <API-type> is "V1" for most endpoints.

• <resource-path> defines the target resource.

3. Making Your First Request

Use this request to retrieve products:
GET /rest/V1/products?searchCriteria[pageSize]=10

The response includes product data in JSON format:

{

"items": [

`{`

  `"id": 1,`

  `"sku": "product-sku",`

  `"name": "Product Name"`

  `// other product attributes`

`}`

`// more products`

],

"search_criteria": {

`"filter_groups": [],`

`"page_size": 10`

},

"total_count": 100

}

4. Common REST Operations

Use these endpoints to perform basic operations:

• Create a product: POST /rest/V1/products

• Update a product: PUT /rest/V1/products/{sku}

• Delete a product: DELETE /rest/V1/products/{sku}

• Get customer data: GET /rest/V1/customers/{customerId}

• Create an order: POST /rest/V1/orders

5. Advanced REST Features

Search criteria for filtering and sorting:

GET /rest/V1/products?searchCriteria[filter_groups][0][filters][0][field]=price

&searchCriteria[filter_groups][0][filters][0][value]=50

&searchCriteria[filter_groups][0][filters][0][condition_type]=gt

Bulk operations to process many entities:

POST /rest/async/bulk/V1/products

Asynchronous endpoints for long-running tasks:

POST /rest/async/V1/products

How to Work With Magento SOAP API Basics?

1. Accessing WSDL

Magento generates WSDL files for each service. Use this format to access the WSDL:

http(s)://<magento-host>/soap/<store-code>?wsdl&services=<service-name>

Example:

To access the catalog service WSDL, use:

https://example.com/soap/all?wsdl&services=catalogProductRepositoryV1

2. Creating a SOAP Client

Use PHP to create a SOAP client:

$client = new SoapClient(

'https://example.com/soap/all?wsdl&services=catalogProductRepositoryV1',

[

`'soap_version' => SOAP_1_2,`

`'stream_context' => stream_context_create([`

  `'http' => [`

    `'header' => 'Authorization: Bearer ' . $token`

  `]`

`])`

]

);

3. Making SOAP Requests

Call methods using the SOAP client:

php

CopyEdit

$result = $client->catalogProductRepositoryV1Get(['sku' => 'product-sku']);
