API Endpoint

An endpoint is the specific URL of an API that a system connects to in order to send or receive data. If the API is the contract that defines how two applications talk to each other, the endpoint is the specific entry point where each operation happens: a URL such as https://api.company.com/v1/customers that exposes a single function (reading, creating, updating or deleting a resource).

Each endpoint combines an HTTP method (GET to read, POST to create, PUT or PATCH to modify, DELETE to remove) with a path that identifies the resource. A single API usually exposes dozens of endpoints, one for each action it allows. In the Salesforce ecosystem, for example, there are endpoints to query accounts, create opportunities or trigger flows, and connecting them to your other tools is the foundation of any integration.

When two systems need to exchange information (a CRM and a billing system, an online store and an ERP), they do not connect in a generic way: they do it through specific endpoints. Each endpoint represents an available action and has its own address. Understanding this concept is key to any integration project, because it defines what can be requested, how it is requested and what comes back in return.

How an endpoint is built

A typical REST endpoint is made up of three pieces that together describe a complete operation:

• The HTTP method, which states the intent: GET to read, POST to create, PUT or PATCH to update and DELETE to remove.
• The base URL, which points to the API server, for example https://api.yourcompany.com/v2.
• The resource path, which identifies the object being acted on, such as /orders or /customers/4821.

So a GET to /customers/4821 means "get me the data for customer 4821", while a POST to /orders means "create a new order with the information I am sending you". Many endpoints also accept parameters (filters, pagination, fields to return) and almost always require authentication, usually via an OAuth token that travels in the header of each call.

Why it matters for the business

For an operations or technology leader, endpoints are the map of what a piece of software lets you automate. If your e-commerce platform exposes an endpoint to check the order status, you can show it to the customer automatically over WhatsApp without anyone looking it up by hand. If your CRM exposes an endpoint to create leads, your web form can add each contact in seconds. The number and quality of available endpoints determine how far you can take automation between your systems.

A concrete example (Argentina/LATAM)

Picture a distributor in Buenos Aires that sells through its online store and manages sales in Salesforce. Every time an order comes in, the site makes a POST to the Salesforce opportunities endpoint to record the sale, and then a GET to the inventory system endpoint to confirm availability. If the customer asks about their shipment, an agent queries the carrier's real-time tracking endpoint. Three different endpoints, three different systems, one seamless experience for the end customer.

Endpoint compared with related concepts

The endpoint is often confused with other terms from the world of integrations. This table clarifies the differences:

The difference from the webhook is the most important one in practice: with an endpoint, you go and get the information when you need it; with a webhook, it is sent to you as soon as an event occurs. Many projects combine both: webhooks to learn about changes instantly and endpoints to query the details.

Common mistakes

• Confusing endpoint with API. The API is the whole set; the endpoint is just one of its doors.
• Ignoring versioning. APIs evolve and publish versions (v1, v2 and onward); an integration pointing to an old version can stop working without warning.
• Underestimating usage limits. Each endpoint usually has rate limiting, a cap on calls per minute or hour; exceeding it stalls your processes.
• Exposing unprotected endpoints. An endpoint without proper authentication is an open door; it should always sit behind tokens and permissions.

Mastering the concept of an endpoint does not require being a programmer, but it does require understanding that every integration you ask for translates, under the hood, into calls to specific endpoints. When you evaluate a new tool, asking which endpoints its API exposes usually reveals in advance how far you will be able to automate.
