Request Application Tokens | Nuapay Developer Hub

The Request Token RESTful API allows you to generate a token for a specific application resource.

API Details

Use the Request Application Access Token Endpoints to generate an OAuth token which represents access for:

A specific resource.
A set of scopes.

Application Friendly Tokens

Application Friendly Tokens:

Can be used by Mobile Apps to call our APIs directly.
As mobile apps are not considered a safe processing environment for credentials, the tokens will be limited to must-have access scopes that are required to deal with an individual resource.
In most cases these will be used for API calls in read-only mode.

Tip: If you use an application token against the wrong resource, you will be presented with a 401 unauthorized response.

The image below illustrates the flow:

Note that:

No IP Filtering is applied.
You will not be able to create resources using an application friendly token.
Calls contribute to your throttling statistics.
All resource creation is still a server-to-server call.
These tokens are available for the products listed below.

open_banking_pis

Note:

When working with our APIs, please use the Sandbox URI when testing and the Live URI when you move to Production.

LIVE     https://api.nuapay.com/tpp
SANDBOX  https://sandbox.nuapay.com/tpp

If you haven't done so already and would like to do some testing, please Request Sandbox Access

Important: Endpoints and Webhooks may be extended from time to time and any changes we make will follow our Versioning and Backward Compatibility rules. This means that the code that you write today must be designed to be robust enough to handle any future changes (where a new object is added to (or removed from) a specific API response, for example).
