Salesforce API Integration capabilities are the powers that are provided by Salesforce, we mentioned each API below to know more read the given points one by one.
1. REST API:
This API is the best for web or mobile applications, regarding data formats. It will use XML or JSON, and its works so brilliantly for web or mobile applications. REST uses less bandwidth and is easily consumed by web browsers, REST focuses on multiple data operations like:
- PUT to update
- Patch
- Delete
- Post to create a record
2. SOAP API:
SOAP API was very common and it is used by older systems. This is the best for system-to-system communication and for applications also that require format hand-off contracts between API and the consumer.
3. BULK API:
The BULK API in Salesforce is capable to manage high-volume messages of up to 100 million records per 24-hour timeframe. This will help by increasing stability, and also allows you to control your message, and monitor your jobs.
4. Real-Time Streaming API
A real-time streaming API allows applications to receive continuous data from a server without repeatedly requesting updates. Streaming APIs differ from REST APIs by maintaining an open channel that enables continuous data delivery and minimizes delay.
In this, push technology and protocols like WebSockets or Server-sent events (SSE) is used. Common use cases include live chat, real-time notifications, and live sports or video updates. Examples include Salesforce Streaming API, PubNub, Ably, Kafka streams, OpenAI real-time API, and YouTube live streaming API.
5. Workflow-Driven Outbound Messages
Workflow-driven outbound messages in Salesforce automatically send data to external systems when specific conditions are met, using workflow rules or flows. These messages use the SOAP protocol to transmit data in XML format. We can map Salesforce fields to match elements in the message, ensuring accurate data delivery.
They are used to trigger actions in external systems like web services or other applications. For example, creating a new opportunity can send a message to a marketing platform to launch a personalized email campaign. Outbound messages support seamless, automatic integrations across platforms.
6. External Web Service Callouts
External web service callouts allow Salesforce to communicate with external systems over HTTP or HTTPS. Callouts can follow the REST architecture with JSON payloads or use the SOAP protocol, which requires XML and a WSDL definition. Callouts can be made using Apex code, Flow Builder, or External Services.
Common use cases include fetching third-party data, updating external CRMs, or triggering events. Key considerations include security, callout limits, read-only restrictions, and proper error handling. Testing tools like mock callouts are available to ensure reliability during development and deployment.
7. On-Demand Data Access with Salesforce Connect
Salesforce Connect helps us to access external data in real-time, without importing or storing it within our Salesforce environment. It uses external objects to mirror data from systems like SAP or SharePoint. It allows users to view and interact with that data instantly.
By establishing a live connection, often through the OData protocol, Salesforce Connect keeps data current without replication. This reduces storage needs and ensures accuracy. We can create a seamless system experience and access external data using familiar Salesforce features like list views, record pages, and custom tabs.
8. Data Synchronization via Heroku Connect
Heroku Connect generally allows seamless data synchronization between Salesforce and a Heroku Postgres database. Through this, we can easily link our CRM with custom applications. It supports one-way or two-way synchronization. We can configure which objects and fields to sync, and the service manages the synchronization process automatically.
Developers can access Salesforce data using standard SQL in Heroku apps. This simplifies integration, reduces custom code, and supports secure, scalable app development- ideal for CRM extensions, data warehousing, or securely sharing sensitive data like PHI or PII.
