WalletsHow Payblr works
Your system communicates with Payblr through REST APIs. Payblr serves as the central integration layer, managing processing behavior behind the scenes.
When your system sends requests such as creating or updating a card, Payblr processes the request and returns the result to your system.
For integrations that require requests to be sent from Payblr into your environment, such as authorizations, Payblr supports EHI (External Host Interface). In these flows, your system hosts the endpoint and Payblr sends requests to you.
Event notifications such as card updates, transaction activity, or other supported events can be delivered to your system using webhooks, so your applications remain synchronized with Payblr activity.
Integration methods
Payblr documentation is organized around the main ways your system connects with Payblr.
| Method | Purpose | Client responsibility |
|---|---|---|
| REST APIs | Used by your system to send requests to Payblr and receive structured responses. | Implement the required API requests, authentication, and response handling. |
| EHI | Used for client-hosted authorization flows where Payblr sends authorization-related requests to your environment. | Host and maintain the required endpoint and respond within the expected processing window. |
| Webhooks | Used for event notifications so your system stays synchronized with Payblr activity. | Configure a webhook endpoint, process events, and log relevant identifiers for troubleshooting. |
