Each item of `results` is the message exactly as it was delivered to your webhook, with the same `message_id`, `event_type`, `issue_datetime` and `payload` you received. The `message_id` is what tells a message you already processed apart from one you did not. Use it to look up a notification you did not process, or to reconcile what was sent against what you have on your side. Messages are returned newest first, and every filter can be combined. The result is always restricted to your own account. Messages issued before this endpoint was released carry no creation date and no recorded operation: they are listed, but the `date_gte`, `date_lte` and `operation_type` filters leave them out. ## OpenAPI ````yaml crypto-as-a-service/openapi.json GET /api/v1/ipn/messages/ openapi: 3.0.2 info: title: B2B API version: '1.0' description: >- B2B API allows a third party to access different use cases and services inside of Ripio ecosystem. It is organized around RESTful constraints, with requests and responses in JSON format, using HTTP in the standard format and the answer codes. The API is designed to be compliant with OpenAPI Specification v3.0, which is a trusted open source standard for HTTP-Based APIs. The API offers the ability to test it with a simple, yet powerful sandbox that will enhance developer experience and replicate production capabilities in a well isolated and safe environment, giving developers full freedom to try the integration without compromises. # Error Handling If a request to B2B REST API fails, the response will contain an five-digit error code with a corresponding error message to indicate the details of the error. The following code snippet is a sample error response that contains an error code and message pair: ```` { "code": 40001, "type": "NotAuthenticated", "detail": { "message": "Authentication credentials were not provided.", "code": "not_authenticated" }, "status": 403 } ```` ## Error Codes | Code | Error Category | Description | Resolution | | :------- | :------ | :------ | :----- | | 20000 | Validation Error | Raised when there is a semantic error in the payload of the request. | Check the docs for precise information on how to provide correct values for each resource atribute. | | 20001 | Parse Error | Raised when the API receives a malformed JSON document. | Check for syntax errors in the payload of your request.

Currently there is only one supported authentication flow: * **clientCredentials** allows you to access your own B2B account (First-Party Integration) and performs transactions against the public API. This oauth2 flow is well suited for this API, as it allows machine-to-machine communication. Every call to the API has to be authenticated with an OAuth2 Token. In order to request this token, you will need to have sandbox or production API Keys (client id and client secret) that will be needed to generate a credential in order to negotiate an ephemeral access token. Every request must be accompianed by an `Authorization` header with a value that follows the following schema: `Bearer ACCESS_TOKEN` ````
