In this blog, we\u2019ll explore both APIs, their key features, and when to use each.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h3 data-pm-slice=\"1 1 []\">What is Salesforce REST API?<\/h3>\n<\/div>\n<div class=\"insight-blog-para\">The <a href=\"https:\/\/developer.salesforce.com\/docs\/atlas.en-us.api_rest.meta\/api_rest\/intro_rest.htm\">Salesforce REST API<\/a> is a web-based interface that allows external systems to access and manipulate Salesforce data using standard HTTP methods. It provides a simple and lightweight way to interact with Salesforce&#8217;s resources and supports common operations like querying, creating, updating, and deleting records.<\/div>\n<div class=\"insight-paralist\">\n<ul>\n<li><strong>Data Formats<\/strong>: The REST API typically returns data in JSON or XML formats, making it easy to integrate with various programming environments.<\/li>\n<li><strong>Supported HTTP Methods<\/strong>: The API leverages standard HTTP methods like GET (retrieve data), POST (create records), PATCH (update records), DELETE (remove records), and PUT (replace data).<\/li>\n<li><strong>Error Handling<\/strong>: The API uses standardized HTTP status codes (e.g., 200 for success, 400 for bad request) to indicate the status of the request, which simplifies error handling for developers.<\/li>\n<\/ul>\n<\/div>\n<div class=\"insight-blog-para\"><strong>Use Cases<\/strong>: REST API is ideal for applications that need simple interactions with Salesforce data, especially when the operations do not require complex relationships or custom aggregations.<\/div>\n<\/div>\n<\/div>\n<div class=\"blog-fact-bx\">\n<div class=\"blog-highlights\">\n<h6>Also Read<\/h6>\n<\/div>\n<p><em><strong>Don\u2019t forget to checkout: <\/strong><a href=\"https:\/\/test.ayaninsights.com\/guestblogs\/tracking-user-activity-in-salesforce\/\">Tracking User Activity in Salesforce: A Complete Guide<\/a>.<\/em><\/p>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h3>What is Salesforce GraphQL API and Why Was It Introduced?<\/h3>\n<\/div>\n<div class=\"insight-blog-para\">The <a href=\"https:\/\/developer.salesforce.com\/docs\/platform\/graphql\/overview\">Salesforce GraphQL API<\/a> provides a more flexible and efficient approach to querying Salesforce data. Unlike traditional REST API endpoints, which require predefined endpoints for specific resources, GraphQL allows you to define the exact data you need in a single query, avoiding unnecessary data transfer.<\/div>\n<div class=\"insight-paralist\">\n<ul>\n<li><strong>Querying<\/strong>: With GraphQL, you can specify the exact fields you want to retrieve for each resource, leading to smaller payloads and optimized performance.<\/li>\n<li><strong>Response Structure<\/strong>: Responses are returned in JSON format and include separate sections for data (the requested fields) and errors (if any issues occurred).<\/li>\n<li><strong>Aggregation and Summarization<\/strong>: GraphQL supports aggregate queries, enabling you to perform calculations like sums, averages, and counts directly in the query, which helps in reducing the need for multiple calls.<\/li>\n<li><strong>Mutations<\/strong>: GraphQL uses mutations to modify Mutations allow you to create, update, or delete records with more flexibility compared to REST API.<\/li>\n<\/ul>\n<\/div>\n<div class=\"insight-blog-para\"><strong>Why It Was Introduced<\/strong>: GraphQL was introduced to address the limitations of REST API in dealing with complex data relationships and performance inefficiencies. It allows developers to request only the data they need, reducing the amount of data sent and improving the speed of data retrieval.<\/div>\n<\/div>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h3>Key Differences Between Salesforce REST API and Salesforce GraphQL API<\/h3>\n<\/div>\n<div class=\"insight-blog-para\">Here\u2019s a quick comparison to highlight the differences between the two APIs:<\/div>\n<\/div>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h5>Field Selection:<\/h5>\n<\/div>\n<div class=\"insight-paralist\">\n<ul>\n<li><strong>GraphQL<\/strong>: Developers can specify exactly which fields are needed, ensuring that only relevant data is returned, optimizing bandwidth and processing time.<\/li>\n<li><strong>REST API<\/strong>: Limited to predefined endpoints and requires additional logic to filter out unnecessary fields, which can increase the data payload.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h5>Data Aggregation:<\/h5>\n<\/div>\n<div class=\"insight-paralist\">\n<ul>\n<li><strong>GraphQL<\/strong>: Supports aggregation directly within the You can use built-in functions like groupBy, count, and sum to fetch summarized data in a single query.<\/li>\n<li><strong>REST API<\/strong>: Typically requires multiple API calls to fetch aggregated data or may involve additional processing on the client side after retrieving the data.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h5>Efficiency:<\/h5>\n<\/div>\n<div class=\"insight-paralist\">\n<ul>\n<li><strong>GraphQL<\/strong>: By allowing the client to specify precisely which data is required, GraphQL minimizes the amount of data transferred and reduces the number of network requests needed.<\/li>\n<li><strong>REST API<\/strong>: Often leads to over-fetching of data (where more data than needed is returned) and can require multiple calls to different endpoints to gather related<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h5>Complex Relationships:<\/h5>\n<\/div>\n<div class=\"insight-paralist\">\n<ul>\n<li><strong>GraphQL<\/strong>: Supports deep relationships and nested queries in one This is particularly beneficial when retrieving related records like Accounts, Contacts, Opportunities, and Cases.<\/li>\n<li><strong>REST API<\/strong>: To retrieve related data, you typically need to make multiple requests to different endpoints, leading to higher latency and complexity.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h5>Introspection:<\/h5>\n<\/div>\n<div class=\"insight-paralist\">\n<ul>\n<li><strong>GraphQL<\/strong>: Supports introspection, allowing developers to query the API for metadata, types, and available This helps explore and understand the API schema dynamically.<\/li>\n<li><strong>REST API<\/strong>: Lacks introspection capabilities, requiring developers to rely on external documentation or manual exploration of the API.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h2>Use Cases for both APIs?<\/h2>\n<h3>Use REST API When:<\/h3>\n<\/div>\n<div class=\"insight-paralist\">\n<ol>\n<li>\n<h5>Simple Operations:<\/h5>\n<ul>\n<li>The REST API is ideal when you\u2019re performing basic CRUD (Create, Read, Update, Delete) operations on individual records, especially when you don\u2019t need to pull complex, related data in one request.<\/li>\n<li>Example: If you need to retrieve a single Account record by ID, the <span style=\"color: green;\">GET \/services\/data\/vXX.X\/sobjects\/Account\/{id}<\/span> endpoint in REST is straightforward and efficient.<\/li>\n<\/ul>\n<\/li>\n<li>\n<h5>Fixed Set of Data:<\/h5>\n<ul>\n<li>REST API is more suitable when you&#8217;re working with a fixed set of data or specific objects where you don\u2019t need to dynamically query fields or handle complex relationships.<\/li>\n<li>Example: A use case where you&#8217;re integrating Salesforce with an external system that only requires basic data like names, addresses, and phone numbers (no complex querying or aggregation needed).<\/li>\n<\/ul>\n<\/li>\n<li>\n<h5>Limited Query Customization:<\/h5>\n<ul>\n<li>REST API supports SOQL (Salesforce Object Query Language) to query records, but the query customization is limited to what is supported in the endpoint.<\/li>\n<li>Example: A simple query like <span style=\"color: green;\">GET \/services\/data\/vXX.X\/query\/?q=SELECT Id, Name FROM Account<\/span> is effective when you&#8217;re just retrieving a few fields without needing complex nested relationships.<\/li>\n<\/ul>\n<\/li>\n<li>\n<h5>When You Need to Work With Standard Endpoints:<\/h5>\n<ul>\n<li>REST API works well when the Salesforce objects and operations you need to interact with are already exposed via standard endpoints.<\/li>\n<li>Example: If you need to update a Contact record, you can send a PATCH request to the endpoint <span style=\"color: green;\">\/services\/data\/vXX.X\/sobjects\/Contact\/{id}<\/span> without needing custom GraphQL queries.<\/li>\n<\/ul>\n<\/li>\n<li>\n<h5>Broad Compatibility:<\/h5>\n<ul>\n<li>REST API is widely supported across different programming languages and tools, making it a go-to solution for many integrations.<\/li>\n<li>Example: If you\u2019re integrating Salesforce with an external system (e.g., a payment gateway) that only understands HTTP requests, REST API is an easy choice.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h3>Use GraphQL API When:<\/h3>\n<\/div>\n<div class=\"insight-blog-para\">Here\u2019s a quick comparison to highlight the differences between the two APIs:<\/div>\n<div class=\"insight-paralist\">\n<ol>\n<li>\n<h5>Fine-Grained Control Over Data Retrieval:<\/h5>\n<ul>\n<li><strong>Field Selection:<\/strong> GraphQL allows you to specify exactly which fields you want returned, minimizing unnecessary data and making your API calls more efficient.<\/li>\n<li><strong>Example:<\/strong> If you only need the <strong>Name<\/strong> and <strong>Phone<\/strong> fields for Contacts, you can structure your query like:<\/li>\n<\/ul>\n<div class=\"blog-grey-box-highlight\">\n<p style=\"color: red;\"><strong>graphql<\/strong><\/p>\n<pre style=\"background: #f4f4f4; padding: 10px; border-left: 5px solid red;\"><code>query { contacts { name phone } }<\/code><\/pre>\n<p>This avoids unnecessary data like <strong>Email<\/strong> or <strong>Address<\/strong>.<\/p>\n<\/div>\n<\/li>\n<li>\n<h5>Complex Queries with Nested Relationships:<\/h5>\n<ul>\n<li><strong>Multiple Objects in One Query:<\/strong> GraphQL allows you to retrieve data from multiple related objects (via relationships like <strong>Account \u2192 Contacts<\/strong>) in a single request, reducing the need for multiple API calls.<\/li>\n<li><strong>Example:<\/strong> If you need to get an <strong>Account<\/strong> record along with its related <strong>Contacts, Opportunities,<\/strong> and <strong>Cases<\/strong>, a single GraphQL query can handle this:<\/li>\n<\/ul>\n<div class=\"blog-grey-box-highlight\">\n<p style=\"color: red;\"><strong>graphql<\/strong><\/p>\n<pre style=\"background: #f4f4f4; padding: 10px; border-left: 5px solid red;\"><code>query { account(id: \"001xxxxxxxxxxxx\") { name contacts { name email } opportunities { name amount } cases { <span style=\"color: red;\">caseNumber<\/span> status } } }<\/code><\/pre>\n<\/div>\n<\/li>\n<li>\n<h5>Aggregation and Summarization of Data:<\/h5>\n<ul>\n<li><strong>Avoid Multiple Calls:<\/strong> GraphQL&#8217;s ability to aggregate and summarize data helps minimize the number of requests, which can be especially beneficial for applications that need to gather large datasets with grouping and ordering.<\/li>\n<li><strong>Example:<\/strong> If you need the total number of <strong>Opportunities<\/strong> grouped by <strong>Stage<\/strong>, a single GraphQL query can be written to aggregate that data:<\/li>\n<\/ul>\n<div class=\"blog-grey-box-highlight\">\n<p style=\"color: red;\"><strong>graphql<\/strong><\/p>\n<pre style=\"background: #f4f4f4; padding: 10px; border-left: 5px solid red;\"><code>query { opportunities(groupBy: \"stage\") { stage count totalAmount } }<\/code><\/pre>\n<\/div>\n<\/li>\n<li>\n<h5>Optimizing Performance with Fewer API Calls:<\/h5>\n<ul>\n<li>GraphQL reduces the need for making multiple requests by fetching all related data in a single call, which leads to lower latency and fewer network round-trips.<\/li>\n<li><strong>Example:<\/strong> In a REST API, fetching an <strong>Account<\/strong> record and all of its related <strong>Contacts, Opportunities,<\/strong> and <strong>Cases<\/strong> would require multiple calls to different endpoints. In GraphQL, this can be achieved in one query.<\/li>\n<\/ul>\n<\/li>\n<li>\n<h5>Dynamic Schema and Metadata:<\/h5>\n<ul>\n<li><strong>Introspection:<\/strong> GraphQL offers introspection capabilities, allowing developers to query the API schema itself to learn about the available data structures, relationships, and queries.<\/li>\n<li><strong>Example:<\/strong> A tool like <strong>GraphiQL<\/strong> (or <strong>Postman<\/strong> with GraphQL support) allows you to explore available queries and mutations dynamically. This can be extremely useful for exploring Salesforce\u2019s data models and understanding available relationships without needing separate documentation.<\/li>\n<\/ul>\n<\/li>\n<li>\n<h5>Real-Time Data and Efficient Mutations:<\/h5>\n<ul>\n<li><strong>Mutations:<\/strong> Just like REST, GraphQL can be used to create, update, and delete records, but it often supports more flexible, compound mutations.<\/li>\n<li><strong>Example:<\/strong> Instead of making separate API calls to update multiple fields of an object, GraphQL can update multiple fields in one mutation:<\/li>\n<\/ul>\n<div class=\"blog-grey-box-highlight\">\n<p style=\"color: red;\"><strong>graphql<\/strong><\/p>\n<pre style=\"background: #f4f4f4; padding: 10px; border-left: 5px solid red;\"><code>mutation { updateContact(id: \"003xxxxxxxxxxxx\", data: {phone: \"555-1234\", email: \"new-email@example.com\"}) { id phone email } }<\/code><\/pre>\n<\/div>\n<\/li>\n<li>\n<h5>When You Have Complex or Changing Data Requirements:<\/h5>\n<ul>\n<li>GraphQL is ideal when you need more flexibility or anticipate changes to your data requirements over time. The client can adapt to different field structures without needing API updates.<\/li>\n<li><strong>Example:<\/strong> If you\u2019re building a dynamic dashboard where the data displayed changes based on user input (e.g., showing different data fields, grouping, or aggregations), GraphQL allows you to modify your queries on the fly.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n<\/div>\n<\/div>\n<\/div>\n<div class=\"insight-entry-blog\">\n<div class=\"insight-blog-content\">\n<div class=\"blog-entry-heading\">\n<h2>Summary of When to Use Each API<\/h2>\n<\/div>\n<div class=\"insight-blog-para\">\n<table style=\"width: 100%; border-collapse: collapse; text-align: left;\">\n<thead>\n<tr style=\"background: #f4f4f4; border-bottom: 2px solid #ddd;\">\n<th style=\"padding: 10px; border: 1px solid #ddd;\">Factor<\/th>\n<th style=\"padding: 10px; border: 1px solid #ddd;\">Salesforce REST API<\/th>\n<th style=\"padding: 10px; border: 1px solid #ddd;\">Salesforce GraphQL API<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #ddd;\"><strong>Simple CRUD operations<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u2705 Perfect for basic operations like Create, Read, Update, and Delete<\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u2705 Can handle these, but might be overkill for simple operations<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #ddd;\"><strong>Field and Data Selection<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u274c Limited field selection and response customization<\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u2705 Full control over data returned, avoiding over-fetching<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #ddd;\"><strong>Multiple Related Objects<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u274c Requires multiple API calls for related data<\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u2705 Fetch multiple related records in a single request<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #ddd;\"><strong>Aggregation\/Summarization<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u274c Requires multiple calls or custom processing<\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u2705 Aggregate data (e.g., sums, counts) in a single query<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #ddd;\"><strong>Performance Efficiency<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u274c Can require multiple calls for related data<\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u2705 Reduces the need for multiple round trips<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #ddd;\"><strong>Introspection<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u274c Does not support introspection<\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u2705 Introspective capabilities allow exploration of schema<\/td>\n<\/tr>\n<tr>\n<td style=\"padding: 10px; border: 1px solid #ddd;\"><strong>Data Structure Flexibility<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u274c Fixed API endpoints with pre-defined fields<\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u2705 Dynamic queries allow flexibility in data requirements<\/td>\n<\/tr>\n<tr style=\"background: #f9f9f9;\">\n<td style=\"padding: 10px; border: 1px solid #ddd;\"><strong>Real-time or Changing Data<\/strong><\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u2705 Simple use cases<\/td>\n<td style=\"padding: 10px; border: 1px solid #ddd;\">\u2705 Ideal for complex or frequently changing data needs<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Salesforce offers multiple APIs to help developers interact with its platform efficiently.
