API specification

Every DSOP solution based on the DSOP Control Common Standard must use this API-specification. The API-specification in Swagger is the technical specification to follow when implementing these API’s.

The API-specification for the DSOP Control Common Standard consist of several API’s, and each API consist of several fields and subfields. All fields are to be provided, delivered (as far as the financial institution has data for the fields) and formatted according to the API-spesification and the description of the fields from the data model, unless otherwise stated for the specific DSOP solution.

A list of the applicable and relevant API’s and the necessary minimum version for each DSOP solution is described in the data model section. The data model also give a full description of the output parameters for the current versions, and specify what fields in each API that should be delivered for each DSOP solution based on the DSOP Control Common Standard.

Link to different versions of the DSOP Control Common Standard is presented in the table below.

Error codes with associated error situations

There are several reasons which can cause errors in the API’s, some of them are:

• Security errors related to access to the API’s.
• Incorrect input parameters either query, header or path parameters
• Invalid combinations of input parameters
• Errors on the Data Providers’ side when they are not able to respond or return data.

The link below describes some of these specific error situations that the Data Consumers may encounter, with http error codes and associated message codes (ACC-xxx) to be returned by the Data Providers. They must be returned in a consistent manner. The intention is to ensure that Data Consumers get harmonized API behaviour across all API providers. The Data Providers will strive to follow the specification as far as possible, and return descriptive messages so that the Data Consumers understand error situations as best as possible.
