SAP exposes its data and transactions through OData services, REST APIs cataloged in the SAP API Business Hub, and older RFC/BAPI calls on systems that predate full OData coverage. Having an API doesn't mean the integration already exists: turning that access into a working sync with your storefront, CRM, or warehouse system is custom development work, which is what we build.
The SAP API Business Hub catalogs prebuilt APIs across SAP's products, S/4HANA, SuccessFactors, Ariba, and more, mostly built on OData, which exposes business objects as queryable, filterable REST-style endpoints. That catalog is a genuinely useful starting point for seeing what's technically possible before anyone writes a line of code.
Older ECC systems that haven't been fully modernized onto OData often still rely on RFC and BAPI calls instead, the older function-call interface SAP's always supported, or IDocs for document-based exchanges like orders and invoices. Which one you're actually working against depends on the SAP version and how much of it has been upgraded, not just which API the documentation happens to describe.
Authentication adds its own layer on top: OAuth 2.0 for cloud-facing OData services, and for on-premise systems, SAP Cloud Connector to bridge a request from outside the network into SAP without opening the whole system to the internet.
A business running SAP usually has someone who can administer it, configure it, run reports out of it. Writing the code that calls SAP's API correctly and maps the result into whatever system needs it is a different skill, and it's rarely in-house.
Prebuilt connector apps cover common, well-trodden scenarios, Shopify, Salesforce, a handful of others. Anything more specific to how your business actually operates runs straight into OData, RFC, or IDocs directly, and an ECC system that's never been exposed through OData sometimes needs a middleware layer built in front of it before an outside system can reach it at all.
When an ECC system hasn't been exposed through full OData coverage, we build the middleware that wraps its RFC and BAPI calls in a REST interface an outside system can actually use, instead of waiting on an upgrade that may be years off.
We build the integration against SAP's OData services so order status, stock levels, or account data flows automatically into the tool your team already works in, rather than someone running a report and emailing it.
Tell us what you're trying to read or write, and which SAP system it's running on, and we'll map out what's actually reachable.
Give us the SAP system you're running and what you're trying to connect it to, and we'll scope whether it's a standard OData call, an RFC wrapper, or something that needs a middleware layer in between. And if SAP's API isn't actually where your project is stuck, tell us what is, since we build this kind of integration work against plenty of systems that aren't SAP.
Let's talk →Yes, though which one depends on the system and version. S/4HANA and most modern SAP products expose OData services cataloged in the SAP API Business Hub. Older ECC systems often still rely on RFC/BAPI calls or IDocs instead, which is a different technical layer to build against.
It's SAP's public catalog of prebuilt APIs across its product line, S/4HANA, SuccessFactors, Ariba, and others, documented in one place so you can see what's technically exposed before committing to a build.
For anything beyond basic read access, yes. Authenticating correctly, handling OData query syntax or RFC calling conventions, and mapping fields into the format another system expects is real development work, which is the part we take on.
SAP's API is direct access to data and business objects inside SAP. Integration Suite is a separate SAP product, a middleware platform for building and running integration flows between SAP and other systems, including ones that call SAP's API underneath. You can build a custom integration against SAP's API directly without ever licensing Integration Suite.
Yes, through browser automation on the side that doesn't have an API, logging into that system's own interface the way a person would, rather than waiting for it to expose one.
