## # Overview

The offers resource is used by an AISP to retrieve the offers available for a specific AccountId or to retrieve the offers detail in bulk for all accounts that the PSU has consented to.

This resource description should be read in conjunction with a compatible Account Information Services API Profile.

## # Endpoints

Endpoints for the resource and available methods.

| Resource | HTTP Operation | Endpoint | Mandatory? | Scope | Grant Type | Idempotency Key | Parameters | Request Object | Response Object
--- | --- | --- | --- | --- | --- | --- | --- | --- | --- | ---
1 | offers | GET | GET /accounts/{AccountId}/offers | Conditional | accounts | Authorization Code | No | Pagination |  | OBReadOffer1
2 | offers | GET | GET /offers | Optional | accounts | Authorization Code | No | Pagination |  | OBReadOffer1

### # GET /accounts/{AccountId}/offers

An AISP may retrieve the offers resource for a specific AccountId (which is retrieved in the call to GET /accounts).

### # GET /offers

If an ASPSP has implemented the bulk retrieval endpoints, an AISP may optionally retrieve the offers in bulk. This will retrieve the resources for all authorised accounts linked to the account-request.

## # Data Model

The OBReadOffer1 object will be used for the call to:

- GET /accounts/{AccountId}/offers
- GET /offers

### # Resource Definition

A resource that contains a set of elements that describes the list of offers available to a specific account (AccountId).

- Generic features (and pricing) for the account product will be not be available via the offers resources. These generic features will be available via the product resource.
- The outcome of any offer (or product feature) uptake will not be reported via the offers resource. The benefits, interest, cash-back for any account will be available via the statements resource (if this is available to PSUs in the existing ASPSP online channel).

An account (AccountId) may have no offers available, or may have multiple offers available.

### # UML Diagram

### # Notes

- Offers (or promotions) for a specific AccountId, which may be viewable in the ASPSP online banking interface, may have a complicated offer structure (which cannot be expressed using a flat Amount, Fee, Rate, or Value structure). In this case, the ASPSP must use the Description field to describe the nature of the offer in free-text

### # Permission Codes

The resource requires the ReadOffers permission. The resource response payload does not differ depending on the permissions granted.
