APIs and integrations

# APIs _and integrations_

Connect your systems and extend what they can do

Connect systems, organise exchanges and track processing in its business context.

[Explore integrations](https://billguard.fr/en/platform/integrations/#integrations) [Discuss your integration](https://billguard.fr/en/contact/?motif=logiciel&source=APIs+and+integrations)

## An open, interoperable ecosystem.

Interfaces connect the software to its environment. Their role, exchanged data and processing responses need to remain understandable.

### Connectors

Connect the tools and services your business uses.

### APIs

Organise exchanges around explicit interface contracts.

### Tailored support

Prepare data, checks and integration tracking.

CONNECTED SYSTEMS

## System families and explicit data flows.

Start with a system family to identify the data, events and responsibilities involved.

-   ### Operators
    
    Service and usage sources.
    
-   ### CRM and sales
    
    Accounts, offers and commercial relationships.
    
-   ### ERP and accounting
    
    Documents and financial records.
    
-   ### Payments
    
    Requests, responses and payment references.
    
-   ### BI and data
    
    Data for analysis and management.
    
-   ### Business tools
    
    Processes specific to your environment.
    
-   ### Third-party services
    
    Interfaces and participants connected to the workflow.

Illustrative system families and flows. Connections are defined around your environment.

## Understand an exchange and handle the response.

An exchange connects a source, processing and a response. If an error occurs, retain the context needed to understand and retry the operation.

Illustrative walkthrough

### Connect responsibilities, not just systems.
